Searched the forum and could not find a clear answer on this. I have a 2003 140" T1N regular high sprinter with factory 225/75r16s. Can I go up to a 235/85r16 without a problem?

Thx, Wade

I only know the 215/85R16 will fit nicely and correct your speedometer. To me this is the ideal tire size for a T1N 140". With 235/85r16 you might get rubbing - I don't know.
If you end up getting the 235/85R16 please report back how well they fit.

I've read rubbing before. Certainly NOT good if you travel anywhere that might get mud or snow in the wheel wells, because they'll rub for sure then.

I just put a set of 235/85 16 on my 2005 T1n

An extra set I had laying around

The rears fit just fine.

The fronts needed some inner wheel well areas cut clear with a grinder. Minor
Also had to trim the front mud flaps.

So far fine. Max load so far has been 2k. A little rub if you go into parking lots too fast. Seem to be on the front mud flap area. I also may have to cut the front fender back a little. Maybe will have to just remove the mud flaps altogether for the summer.

It is a very tight fit, too tight for me. I will not keep them on after the summer.
Snow pack in the wheel wells will be an issue. Does not look like it will work for winter driving

Rides fine. 55 psi in front and 70psi in rears.

Just ordered front and rear Konis. I imagine this will help the ride considerably from what I read.

Thanks guys. I'm going to stick with stock sizing.

One more problem you might have to deal with is the spare. The cage that holds the spare is only so big, so you probably wouldn't be able to get a 235/85 tire to fit. Because of this, your stock sized tire on one wheel and three other wheels with the larger ones will throw the van into limp mode quick.
I say this because I'm in the same boat with my 18" wheels and larger than stock tires.

Eric has this size tyres on one of his 4x4 T1Ns. Bare in mind there is about 2 inches more lift in the suspension on the factory 4x4 T1N, and he still had to cut the guards front and rear to stop rubbing. (front of rear arch, rear of front arch)

It might be ok if you are just on roads, but if you use all of your suspension travel and steering lock then you will rub on uncut guards even on the rear. This is a pic of his van with that 235/85R16 size and cut guards.

What about 245/75? They would be wider but have a smaller aspect ratio (17mm less height). Anyone use those?

Typo in the above. I meant 245/70. Anyway. I decided to stick with stock 225/75. The 245/70 would definitely fit but they were $40 more expensive per tire in the model I wanted. I didn't think it was worth it for 20mm more tread width.

wider tires have less traction* and use more fuel.
*unless you need to disperse your weight, such as driving on sand

Hey all, I went with the stock size 225/75R16. I'll post a pick, but I think they look pretty good. A little narrower than I'd like but not bad at all. Plus this size was $40 per tire cheaper than the next width up.
