Hey I was wondering what the biggest size tires I could get without a lift. I dont want to pay like 600 to get the lift on and then raise up the bumper so that big space isnt there. But what is the biggest size tires can i get w/o a lift? in both ???/??R17 ??x??R17 in both ways, thanks

 

If you keep the stock wheels and crank up the torsion bars, you can fit a 315/70-17 (35x12.50). However, this is an extremely tight fit and the secret appears to be using the stock 17x7.5 inch wheels. Personally, I wouldn't go that big unless you plan on a lift in the future. I think you would be better off staying with a 285/70-17 (33x11.50) or a 33x12.50-17. That way, if you choose to go to a wider aftermarket wheel in the future you can do it without a lift.

 

The man knows what he's talking about. I have the 315/70/17s on my stock 01 4x4 SCrew and am playing he!! trying to find an aftermaket custom wheel that will fit that tire without lifting my truck.....

 

The wheels that i have now are aftermarket wheels so they are 16, they are 17s but i dont know how wide they are. So when i get new tires, i just tell them to crank up the torsion bars? How high do I crank them? And i can fit 33x12.50R17 without a lift? and 33x12.5R17 is the same as 285/75R17 right?

 

285/75/17 is a 33.8x11.2x17.....Are your wheels 16s or 17s? You say both in the first line of your last post.....

 

No one makes a 285/75-17. A few people make 285/70-17's which are approximately a 33x11.50-17. You can fit these on a stock 4x4.

 

i meant to put they arent stock rims so they arent 16 they are 17. (sry about that) So if i dont get the lift i should just got with 285/70R17 and that is it my rims are 17x?.

 

Do you still have the same rims that are pictured on your truck in your gallary? If you do, they are OEM Ford 17x7.5 inch wheels. If you have those wheels, I would go with a 285/70-17 or a 33x12.50-17. If you have different wheels, I would still go with one of those sizes.

 

Cranking up the torsion bars will work, but it makes for a rough ride. You can goto www.central4wd.com they have a torsion leveling kit for your truck which is just 2 new torsion keys that are cut different so that they will lift your truck 1 1/2" while maintaining the factory ride, they're easy to swap in. I have them on my 2002 F150 Supercrew FX4 and the 305/45/22" Cooper XST's are 32.8 inches tall, they don't look that tall in my gallery pics, but they are, and they don't hit anywhere even with the 22x9.5" rims. The new torsion keys are about $120, but worth every penny if you want to keep the factory ride. Just an option.

The aftermarket keys do the same thing as cranking up your torsion bars. You are just increasing the preload on the torsion bars. 6 of one, 1/2 dozen of the other.
