Looking to upgrade your Ford Transit stock tires for larger diameter to improve ground clearance and traction? We were too! Here is the data we gathered during our research.
Let’s get straight to the point. Before we took possession of the van, we upgraded immediately to BF Goodrich KO2 All-Terrain tires.
The KO2 are all-terrain, snow approved (there is the snowflake on it) badass tires.
BF Goodrich KO2 tire.
First of all, what does all those number means?
LT225/75/R16E
- 225: The first 3 digits are the tire width in millimeters (225mm tire diameter)
- 75: The second 2 digits are the tire aspect ratio in percentage (ratio of the sidewall height to its width). (75%)
- R16: The is the diameter of the wheel the tire is intended to fit. (16″ wheel diameter)
- LT: Light Truck metric size intended for vehicule capable of carrying heavy cargo or towing large trailers.
- E: Load Range / Ply Rating. (D = 8 plies, E = 10 plies). Check this article for more info.
What is the Ford Transit stock size tires?
Our 2016 Ford Transit came equipped with stock tires Continental VancoFourSeasons 235/65/R16C. They are 28″ diameter.
What KO2 tires can be installed on factory wheels?
| Tire Size, Load Index & Speed Rating | Rim Width Range (Min/Max) | Section Width on Measuring Rim Width | Overall Diameter | Max Load, Single (lb @ PSI) | Tire Weight | Buy Link |
| LT255/70R16/E 120 S | 6.5″ – 8″ | 10.2″ on 7.5″ | 30″ | 3085@80 | 47.7 | amzn.to/2yvGLGG |
| LT225/75R16/E 115 S | 6″ – 7″ | 8.8″ on 6″ | 29.2″ | 2680@80 | 42.4 | amzn.to/2R6qeQq |
| *LT245/75R16/E 120 S | 6.5″ – 8″ | 9.8″ on 7″ | 30.4″ | 3042@80 | 48.9 | amzn.to/2R9TZzK |
Notes:
- The LT225/75R16/E 115 S don’t need modification and is a good size if you intend to use snow chains (we tested it), but the weight rating is lower than the Ford Transit GVWR. Some installers will refuse to install them because of that. If you still decide to go with the LT225/75R16/E 115 S, it is your responsibility to ensure you don’t overload them. This size fits in the Ford Transit spare tire carrier.
- The LT255/70R16/E 120 S don’t need modification and the weight rating is within range. We haven’t try them with snow chains yet, we will report back after 2018/2019 winter!
- * The LT245/75R16/E 120 S can be installed on factory wheels and the weight rating is within range, but some modifications are required to the van; see Morey’s in Transit How-To. This size fits in the Ford Transit spare tire carrier of the 148WB extended-length body only (or check out how the Morey’s made it work with their 148WB regular length body).
What size did we actually try?
1- LT225/75R16/E 115 S
We got 44k miles out of them, including the spare in the rotation (so 5 tires). It’s not a lot, but keep in mind they’re made for traction not for wear life!
How is the clearance with the LT225/75R16/E 115 S?
Note that for the front tires, minimum clearance is achieved when wheels are fully turned. The clearance shown below is for straight wheels.
Front:
Rear:
How about snow chains with LT225/75R16/E 115 S?
We used THULE/KONIG XG-12 PRO SIZE 245 (amzn.to/2SkfbVh) snow chains with them. Here is our full review:
2- LT255/70R16/E 120 S
We loved our first set of BFGoodrich KO2 so we stick with them for our second set. This time, we are trying the LT255/70R16/E 120 S because the weight rating is higher, the diameter is slightly larger and no modification to the van is required; we’re curious to find out if we notice any difference!
Matching Snow Chains: THULE/KONIG XG-12 PRO SIZE 255 (amzn.to/2qcMLQ6)
Wait for it! We are about to install them in the upcoming weeks (November 2018). We will report back with clearance, snow chains and all when we can…
Why did we choose larger, all-terrain, BF Goodrich KO2 A/T tires?
- All Terrain tread to get us to the trailheads
- Winter approved
- To increase ground clearance
- Great reviews on the Interwebs
Larger tires will affect speedometer reading
The larger tires will decrease the speedometer reading of about 3-4 mph. For example if the speedometer reads 55 mph, our true speed is 58-59 mph. We have to keep that in mind to avoid speeding tickets!
How are the KO2 in snow?
They are great. In fact, we spent last winter snow chasing all over the place: Utah, Wyoming, Washington, Montana & British Columbia (see our Fifth and Sixth month report). We went to ski resorts but also to remote places for backcountry skiing. We drove on all kinds of conditions: dry pavement, black ice, hard pack snow, fresh fluffy snow, you name it. We could go everywhere we wanted (keeping in mind we’re not a snowmobile) and we didn’t have to use the snow chains (except once where it was mandatory) or the Maxtrax. We made it!
Here is more info about living in the van during winter (4×4, snow chains, LSD, maxtrax, etc):
Conclusion
The BFGoodrich KO2 have superior traction in sand or in snow, they look great on the van and the rolling noise is very acceptable for all terrain tires. We highly recommend them!

Out of curiosity, did you consider the 245/70/16 when you were looking at getting new tires at all? Just curious because i’m torn between your old size and the 245/70 as they are just slightly bigger and wider, trying to figure out if i want skinnier or wider. Both fit the chains but of course different sized chains.
Comment by Antoine
Antoine November 13, 2018 at 4:06 pm
I don’t feel like trimming the pinch weld, so I haven’t consider them. Check the Morey’s post for more info (link above in the article)

I noticed you have the Quigley 4×4 lift on your van. Do you think the LT255/70R16 would fit on a van with stock suspension or does the lift factor into the tires that will fit? I currently have LT225/75R16 installed but it’s time to replace them. It seems I have about the same tire clearance as you do. Also thank you so much for your blog. I used it quite a bit during my build and highly recommended it to others!
Thanks!

Hi Brandon,
In fact we DON’T have the 4×4; we have the stock suspension and factory wheels 🙂 So we think the LT255/70R16 will fit! We’ll give them a shot in a few weeks when our LT225/75R16 are worn out.
Have a good one,
antoine

Any idea if the LT255/70R16/E 120 S will fit in the spare tire holder? We have a 148WB regular length.
Comment by Antoine
Antoine November 5, 2018 at 9:42 am
I doubt it (since you have the regular length), but you could replicate what the Morey’s have done (link in article).

Comment by Sepehr Dijouri
Sepehr Dijouri August 29, 2018 at 8:56 am
Correct me if I am wrong, but that tire size (LT225/75R16 LRE) does not hold the same weight as the OEM tires…
The Continental tires max load is 3195lbs @ 90psi, That is what the tire is capable of. A diesel ford transit requires 52PSI in the front and 71 PSI in the rear. 3195lbs/90psi = 35.5lbs per psi is what the Conti holds. If you Multiply the front and rear psi you will get what the transit holds out of the factory.
Front @52psi will hold 1846lbs
Rear @71psi will hold 2520.5lbs
The BFG tires max load is 2680lbs @ 80psi = 33.5lbs per psi. So the new tire pressure should be Fronts 55psi, rears 75psi to hold the same weight out of the factory
So it will hold what the factory holds, but you are limited to 2680lbs @ 80psi…
Comment by Antoine
Antoine September 1, 2018 at 11:20 am
It’s true that they hold less than the factory tires.
I don’t know about your calculations (xxlbs per psi), but you could have your van weighted fully loaded (front and rear axle) to determine exactly what’s the load on each tire; then you can be sure you’re not above the tire capacity. If that’s the case, you could look into the 245/75R16 as they have a higher load rating.
Cheers!

I kept getting stuck in the snow, so put these tires on my transit this winter. If you are in a state where you get any snow. They fit. I love them, have had them around 7 months. I put them on my Jeep also. Thanks for posting this. I know more about tires and load ratings than I want to. BF Goodrich KO2 are the best, and they look cool also.

Cat May 2, 2018 at 7:05 pm
Re: the KO2 tires- did availability of tires factor into your decision (i.e. getting a flat when out and about and being able to replace it relatively easily) Also, are you in a situation where if you have to replace one tire, you have to replace all of them? (happened with my subaru even with relatively new tires).
thank you for all the details, specs and links! your website is a trove of info nd guidance!
Comment by Antoine
Antoine May 3, 2018 at 11:11 am
Hi!
We didn’t factor availability, but the KO2 are popular and very easy to find. The KO2 can be installed on any wheel; so you can change only one tire.
Good luck!

Hi, I love your website. Very informative. I just bought a 2017 ford transit van and am very excited to take delivery of it but I am sooooooo overwhelmed. I do not have any experience with this type of work plus the van took a lot of my money. I want to raise the roof and, of course, build it out inside. I will be coming back to you site over and over again for help. The cheapest fiberglass roof I’ve found is about 2K. Any other suggestions?

Sorry we haven’t look into roof so we’re not much help on that topic… Good luck!

Thanks for all the great info. I love the idea of going with the BF Goodrich KO2 LT225/75/R16E All-Terrain tire. How well are they wearing? I find the stock tires struggle to get 50k miles.
Comment by Antoine
Antoine April 8, 2018 at 11:57 am
We’re at 32k miles and I’m pretty sure the tires will make it to 50k. The reviews we read online were positive about the wearing. We will buy the KO2 again after ours wear out!

Slavomir March 18, 2018 at 2:51 pm
Hi guys, we just ordered our van! Since you’ve been on the road for a while, if doing it again, would you buy the same tires? How is the road noise on them? We also want to get nice looking rims, but between Discount Tire and Les Schwab only 3 show up as options and I was wondering if there is some catch with this. Thanks for running this amazing website! We plan to use a bunch of your links once the build begins.
Comment by Antoine
Antoine March 19, 2018 at 11:15 am
Hi and congratulation for the van!!
We would buy the same tires. We don’t noticed road noise (especially since the van is insulated) and they do the job in summer/winter.
We don’t know about the rims; we just use wheel covers on the factory wheels.
Good luck and THANKS in advance for using our links 🙂
Cheers!

Any chance you know what you paid the dealer for the tires/installation. I just received a price from my dealer for $967.

Don’t recall, sorry. You could inquire at 3-4 places and compare.

Comment by Bruce
Bruce March 8, 2018 at 12:47 pm
The one thing that I didn’t like about the Transit was the design of the rims so to hide them I ordered the silver hubcaps but plan on painting them all black with Plasti Dip to match the black van that I just ordered.
Comment by Antoine
Antoine March 8, 2018 at 1:08 pm
We have wheelcaps too, but didn’t paint them. This will look good for sure!

You know Nokian makes a tire that meets the weight specs for the transit it’s call a Hakkapeliitta C3 (with studs) or CR3 (studless).

Matthew Morey January 10, 2018 at 9:22 pm
Did you guys also replace the spare tire with the KO2 LT225/75/R16E? Does it fit the spare tire spot?
Comment by Antoine
Antoine January 11, 2018 at 9:42 am
We did, it fits in the spare tire spot.
We include the spare into tires rotation and we learned the spare doesn’t have a tire pressure sensor… the van computer is constantly showing a “Tire Pressure Sensor Error” and that’s annoying (we can’t see outside temp, MPEG, etc). Next time we change our tires, we will install a sensor in the spare!
Cheers!

Justin January 6, 2018 at 4:42 pm
Do you know of any problems or have any concerns about the larger tires affecting the shift points of the transmission due to the slight change in the speedometer?
Thank you! Your website is great!
Comment by Antoine
Antoine January 7, 2018 at 9:52 am
We have the 4.1 transmission ratio, but the Transit can also be ordered with the 3.73 ratio. With our larger tires we’re probably somewhere in between 4.1 and 3.73, so I doubt it’s a problem. Also, many people have installed larger tires with no issues.
cheers!

We are planning on being gone for as long as… as long as we can hike, walk and drive!
One other question for you. When building… in what order did you do insulation and wiring? What wiring did you use? It looks flat…
Perhaps we will meet up some day!
Cheers!
Comment by Antoine
Antoine December 8, 2017 at 8:33 pm
We did insulation first, then wiring. This way the wiring is more accessible for modification later (if needed…).
It looks flat because it comes with the positive wire (red) and negative wire (black) into a white protective sleeve; it’s called duplex. For example duplex AWG 14 is referred as 14/2: http://amzn.to/2B48Qau .
Hope that helps!

Hi Guys,
Just got our used 2015 Transit T250 HT 148. Very excited and you should be getting a huge kick back from all my purchases. I really want to put the 245s on but am a bit nervous with the rubbing possibility. Planning to hit the road for good in March. West Coast up to Alaska then next fall and from then on Central and South Americas. Do you know of anyone who did install the 245s? Thanks in advance.
Comment by Antoine
Antoine November 17, 2017 at 6:30 pm
Wow, sounds like a plan!! Solid itinerary! How long are you planning for?
I don’t know someone personally, but I’ve read on the discussion forum (here) that it can be done and there should be no rubbing.
THANKS for using our links 🙂
Have a good one!
Comment by Eric
Eric March 2, 2018 at 12:36 pm
Hi dos Chicas, I have 245/75/16 installed and I really like them. I have a 4 bike rack on the back and it the added height allows the rack to fully extend to the ground so the rear doors can open. The larger tires also look more natural than the small skateboard wheels that come stock. I do recommend eventually changing your gears from 3.31 to 3.73. Once you do this there is no change to the speedometer since the gears make up for the change in tire diameter.
Comment by Antoine
Antoine March 2, 2018 at 8:50 pm
Hi!
Thanks for the input!
`But we have the 4.10 transmission ratio because of the 3.7L engine and the extended-length.
Cheers 🙂

Hey there!,
First off your website is the bomb.com! Second off and the point of this reply to your post is I’m nearly finished with my van build and winter is a comin! Sooo I need new tires (rear wheel drive is fun until you have to drive in a straight line) for ski season. I live in the front range of Colorado and plan to drive about 15k miles this winter with a big trip up to Banff/Revelstoke for several weeks, a Montana trip, Wyoming, Utah, okay you get the picture LOTS OF STOKE CHASING, gas burning, coffee drinking road trips are in my near future. *Insert snow dance here*
So, originally I was planning to go with your idea and buy K02’s with chains for when I have to hit the ‘oh sh*t’ button. Annddd then I read the post from Lifeakimbo that you have a link to in this page.. So in your opinion should I stick with the K02 idea with chains or go with studs and no chains?
Your opinion is much appreciated!
Comment by Antoine
Antoine November 5, 2017 at 10:48 pm
Hi!
We got the KO2 because we’re travelling full time and we didn’t want having to swap the tires for winter/summer during our trip. If we were weekend warriors (with a house as a home base), we would probably install studded winter tires during winter, then swap for A/T tire during summer. It’s probably the best thing to do!
Hope that helps!
Comment by Yann
Yann October 27, 2017 at 2:27 pm
Bonjour,
Pourquoi avez-vous choisi LT225/75/R16E?
Ford me dit que le Transit 250 est offset de 4% avec ctte taille et peut endommager les suspensions.
Ils recommendent LT215/70/R16C
Comment by Antoine
Antoine October 28, 2017 at 1:03 pm
Des pneus plus gros donne une meilleure traction et un plus grand dégagement avec le sol (pour le hors-route).
En effet, nous avons observé que l’odomètre est environ 4% offset, mais ça ne nous dérange pas vraiment…
Pour la suspension, j’en doute. Plusieurs personnes installent même des LT245 (et même 265). Évidemment le concessionnaire Ford ne vous conseillera pas autre chose que ce qui est “standard”.
Voilà!
Au plaisir, antoine

Hi do you have any troubles with rubbing on any part of the vehicle, with the tyres. And did you have to have any modifications to fit them
Comment by Antoine
Antoine October 2, 2017 at 9:47 pm
No rubbing, no modification. The tires are mounted on the stock rims. Some folks installed bigger tires (245) without rubbing.

We JUST got our van on Friday and I asked about bigger tires but we were so excited, my wife and I both forgot to follow up before driving off…
Did Ford do the tire swap or did you have to do it elsewhere? Were you able to exchange or did you have to sell the tires?
Thanks for a great blog.
Comment by Antoine
Antoine September 18, 2017 at 12:36 pm
Ford did it before we took possession of the van, but didn’t exchange them (we had to pay for tire install). We then sold the old tires on Craiglist (as new tires since they have no mileage on them).
Good day!

Are the tire chains in your link (KONIG 12mm XG12 Pro Deluxe SUV/Crossover Snow Chain, Size 245) the correct size (245s) for the BF Goodrich (LT245/75/R16E) that you purchased?
I have studded ice tires on my Fiesta ST for winter fun – virtually like on rails – I couldn’t be happier!!! The BF G T/A’s are certainly top choice for my van. Another blogger said he lost about 1 mpg with the T/A”s from his stock tires on his van.
Comment by Antoine
Antoine August 9, 2017 at 9:41 pm
We installed the KO2 right from the beginning, so we haven’t measured the actual MPG loss; 1 mpg sounds about right.
Here is the link for the Konig fitting chart:
https://konigchain.com/fitguide-consumer/
(hint: click on “I can’t find my car” to go by tire size). Using this guide, i got König XG-12 PRO 255 for the 245/75R16 tires.

Did the BFG AT reduce your MPG?
Comment by Antoine
Antoine July 7, 2017 at 5:17 pm
We installed them from the very beginning, so we can’t tell. That being said, i’m sure badass AT tires reduce the MPG…
With the conversion 95% finished, high-roof, extended-length, 4.10 Transmission ratio, 3.7 engine, our MPG is at about 15.
