That's pretty close. All its going to do is pull the sidewalls together and bulge the center of the tread out when you're properly inflated. You can probably combat this by running a lower pressure, but that will affect MPG and the life of the tires.

Its so close though that i'd almost say just go for it. Rims aint cheap, and I seriously doubt the cost of new rims would be made up for by the little bit longer tire life you're going to get by running the "correct" width.

good luck,

I do it on my truck in the winter. I have 35x12.5 BFG Mud TAs that are on 18x9's in the summer and on the stock wheels in the winter. No problems at all. So far they have about 45000 miles on them and are wearing great. I do rotate them every oil change

 

I run 37x12.5's on my stock 17's theyre doin fine!!

 

there are lots of people around my area the run the toyo mts on stock 18s, you should be fine

damn, you have 45k on bfg muds??

 

Thanks guys I appreciate the quick responses.

Yeah I usually get about 50-55k on them and sell them with about 25% tread left. Like I said I rotate them every 3000 miles and keep the truck aligned. The 33's that I ran on my 97 seem to last a little longer than the 35's on my 06. I don't know if I'm going to get 55k out of them and still have enough left to sell them

 

Should be fine.

I run a 325/60R18 (wider than a 35/12.5) on the stock 18x8s with no issues.

 

That is awesome. I had BFG muds on my old grand cherokee and loved them, but got sticker shock when i priced a set for the SD.

 

Well I put my DR 2.5 leveling kit and 35x12.50-18 Toyo Open Country MT's on the stock 18's today. Overall, the look is great and ride is pretty good too. All I need to do now is get an alignment and I will be good to go. :thanks:

 

I've been thinking of doing that to my 07 6.0. Do you have any pics so I can see what it looks like?

 

:nopics


inquiring minds and fellow 06 F350 owners want to know how it looks

 

As soon as I get the chance I'll get a picture posted.
