As a part of my TriStar project, I will be installing 225/75R16 tires (29.2" tall) and the Fast Forward lift kit. Below is photos of a 225/75R16 being test fitted on our TriStar and a floor jack simulating a lift kit as we do not have this installed as of yet.
What is the BIGGEST size of tire that you can install on a
As you can see from the above photos, minor fender trimming is needed to accommodate tires larger than 29.25" tall. I would have to say with the 32" tires installed that you would have to do a little more trimming again.
There are a few other factors to consider when running larger tires and the biggest one is the hit on performance you will take. The bigger the tire the more sluggish the van will feel unless you change you gearing or upgrade the motor with something with more power. My Syncro Westfalia Joker has stock gearing but the stronger 112hp European 2.1L motor and I have no problems with my 215/85R16 tires. I have run 29" tall tires with stock 2.1L 90hp engines and have found the performance to be acceptable.
