What is the largest tire I can fit with a stock suspension? 2001 F250 crew 4X4. Im thinking 305/75.. I plan to put a leveling kit up front after I get the tires.

Unfortunately, trucks aren't made on a precision CNC table so, the exact place where the hub ends up in the wheel opening has some differences from truck to truck. It probably has more to do with the body mounts than the diff on the frame. But this means that what works on somebody else's truck won't necessarily work on yours...

BUT, I think a 305's gonna be tight. My 285's come within 3/4" in one inside corner in full lock.

I run 305/65r17's on my 00. Minor rubbing on the plastic wheel liner when at full lock on uneven ground. I do have about 1/4" of extra spacing due to the Dynatrac kit. Back spacing on the wheels will also be important.

I ran 305/75/16 on stock wheels and stock 4x4 truck. Minor rubbing but I was happy.

My buddy runs a 285/75/16 MT on stock wheels, no leveling kit on his '99. It rubs at full lock but not too bad.

Air Dog 150, ITP reg. return
Bulletproof oil bypass system

Ride rite air springs in the rear
EGT, boost, and fuel pressure gauges by DiProcol on the pillar

Plus a few other odds and ends...

I've run 285's and 35/12.50/16.5's on my red truck, no rubbing with the 285's, but deffinitly with the 35's... had to trim the bumper, and heated the inner fender at the rear of the wheel well to push it back a little to clear, then added a leaf in the front. Running the 35's now, only rub once in a while, on a bind.

Like they said, each truck is diffrent... my yellow dually, the 245's on it rub the inner fender, it's stock and sagged bad in the front.
