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.

First of all, what does all those number means?


  • 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.



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, except when we are driving on a soft-packed layer of snow over a layer of ice; just like a pickup truck (no 4×4), the rear of the Transit is light and tires will spin easily even with the Limited Slip Differential. We see that happens in ski resort parking lots and such (not on paved road).

For this reason, we carry Thule (now Konig) XG12 PRO snow chains ( See our post on snow chains here:

Wait for it!

Many people opts for studded winter tires and swear by it. They truly are effective on ice. Lifeakimbo installed Nokian Hakkapeliitta LT2; you can read about it here.

Hello! We’re Isabelle and Antoine, a couple dreaming of being on the move and we’re seeking for the ride of our life. We bought a Ford Transit van, converted it to a campervan, sold our house and hit the road full-time to make our dream a reality. We are sharing this in hope of inspiring and helping others to follow their dreams too!

    When you put the larger tires on did those fit on the factory wheels?

      Yes, we mounted the larger tires on the factory wheels!

    Can the speedo be recalibrated for the larger tires?

      We heard of many people who tried at their Ford dealer, but I don’t think anyone had a positive response. We learnt to live with it!

    Did the BFG AT reduce your MPG?

    • Comment by Antoine

      Antoine Reply 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.

    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.

      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:

      (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 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!

    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 Reply 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.
