Ford Transit Larger Tires Upgrade

.

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 LT225/75/R16E All-Terrain tires.

First Ride Avila

 

The KO2 are all-terrain, snow approved (there is the snowflake on it) badass tires.

How is the clearance?

Note that for the front tires, minimum clearance is achieved when wheels are fully turned. The clearance shown below is for straight wheels.

Front:

BF Goodrich KO2 on Ford Transit Clearance (2) BF Goodrich KO2 on Ford Transit Clearance (4)

 

Rear:

BF Goodrich KO2 on Ford Transit Clearance (3) BF Goodrich KO2 on Ford Transit Clearance (1)

 

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 was equipped with stock tires Continental VancoFourSeasons 235/65/R16C. They are 28″ diameter.

VancoFourSeasons

 

What is the largest tire diameter that can be installed without rubbing?

(data gathered from FordTransitUsaForum)

  • Stock factory tires diameter: 28″ (235/65/R16C)
  • Best compromise and enough clearance for chains: 29.2″ (LT225/75/R16E)
  • Largest diameter without rubbing, probably no clearance for chains (to be confirmed): 30.4″ (LT245/75/R16E)
  • We’ve seen people installed larger tires, but some has reported rubbing, some not…

 

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!

    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.

    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!

      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?

    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 Reply 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!

    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.

      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!

    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.

      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).

    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 Reply 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!

    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 Reply 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 Reply 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.

      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!

      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.

        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!

      Antoine Reply 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!

    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 Reply 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

      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.

      Antoine Reply 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 Reply 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.

      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.
