I have a 97 f150 4wd with a fabtech lift (6") glassworks fenders up front and stock rear fenders.

Wanting to try to fit in 37x12.50 (or 13.50) on 16x8-16x10 wheels. Truck is being built up now so wanting to order wheels and tires. I was just curious on why the fabtech lifts say 35x1250 max. What rubs? where, why..

I think the problem with running 37's is the tire will probably come into contact with the firewall if you hit a bump. Another problem with the bigger tires is that they are goign to wear out your steering components faster. In the rear you would probably need to pull the bedsides to make sure that ther rear tires would not rub when the suspension is compressed. You may also want to ask this question at Race Dezert and click on dezert people then post a ? in the shop section. The guys there are good people and KNOW all about what you have and the good and bad of 37's.

 

thanks a million. I didn't look at the firewall issue much was considering just radiusing it in a little bit.

Thanks for your time

i really can't say for sure but i think it would be close to what i have setup 37x13.50r16's x-terrain's with a 4" pro comp,1" TT and a 3" body lift i know i have about 2" more lift in the front but u also have glass so i say try it if u want 37's and if they do rub too bad than give it a 2" body lift i don't know just my 2 cents

 

1" tt?? what is that? I might have seen it but don't know what it is called.

I think he means he adjusted his torsion bars to give him an extra inch. I got about 1.5" of front end lift from my torsion bar adjustment. With 6", you'd be cutting it close for 37s. I'd say get a 2" body lift (or 3"since they are the same price) and be sure. I've had friends who fit 36x14.5R16 with only a 4" and some adjusting. But each truck is different. If you get 37s, I'd definetely go with a 10" wide rim. This will widen the track and will make it fit better in the rear. With a 6" and some torsion bar adjustment in the front, you can probably get 37s under there, but under moderate->heavy compression (like light offroading) I would bet there would still be some rubbing. I'd grab a 3" body (or 2") and then you'll be fine for sure.

 

Well looks like a body lift is going under the truck I just am not fond of them thats the only reason i am leary of them.

Thanks again all for the help. Need to think if I really need to go with 37's or if 35's will do for now hummm

I don't think that you really need to go with a 37's. They are just going to be harder on your suspension and steering. I like the way the 35's look on my truck and they look plent mean. Heck if I really wanted to I could park my truck on one of thoses lowered ricers cars that are so plentiful out here in So Cal. As far as definatley going with a 10" wide to give more of a front track I would say that should not really be a factor in this equation. You may pick up at most 2" over a 8" rim, in the big picture not really that much and now your rims may be more likely to be damaged due to less bulge of the tire. If you want to go larger than 12.5" tires in the future though you need to go with a wider than 8" rim. I would go with whatever looks the best in your eyes.

 

I agree with Crazy4Ford about the 10" rim not being a necessity. However, if you are going to get 37s, an 8" will make the tires seem very tall and not very wide. If you are getting 35s that changes everything.

There are several people on here with 37s and some with 35s. I have 35s and I love my truck. But man, the ones with 37s look soooo sweet too.
