The stock wheels are 7" wide. The 305s are kinda pushing it on stock wheels. The wheels are narrower than the reccommended widths so you may run into warranty issues with the tire manufacturer. Thats why I used to run 285s and not 305s, the tire store wouldn't even sell them to me unless I got some 8" wheels or I had to sign a waiver signing off on any warranty on the tires.
I assume your truck is a 4x4. If it is then you can crank the torsion bars up a little bit. Follow the bars back to the crossmember and there will be a bolt on each side. Jack up the truck and turn each bolt about the same number of times. Do it about 1/2 a turn at a time.

hey there Smokey, your supercrew looks AWESOME with those rims and tires. Did you have to crank the bars? Do you get any rubbing with those rims and tires. I just have a regular 01 4x supercrew, I wonder if it makes a difference with the tire size. Im want to to run a BF Goodrich 305 70 16 on 16x8 Ultrawheel En4cer's, but the tire guy said that if i go any higher than a 285 it will rub. Think I can go with the 16x10 with the 305's?
Anyone else?

Yes you are right it is personal perference on Big (Wider) rim & tire set up or the Taller tire & narrow rim set up. But one thing need to keep in mind is that most of the tire manufactures do not recomend installing bigger tires on the narrow rim (ie 305s or larger on the factory 7.5" rim). Safety issue as well as warrenty issue.

Yes you are correct. I based my decision on the tests 4wheelparts conducted on the f series trucks with the 33" Procomp tires. They concluded that the 33/12.5/17 Procomp tire (either MT or AT) is acceptable to run on a 97-up f-150 with the stock rim even though the tire states an 8" rim is needed.
A taller tire will have better results than the shorter one because the sidewalls will flex more. So I concluded that the 35" would be better than the 33".
I could care less about a tire warranty. First off the MT doesn't have a warranty and secondly, those companies just screw you around with warranties anyways. All that warranty does is lock you into having to purchase the same tire again and again. With their pro-rating system based on retail price, you end up paying just as much for the tire even under warranty. I just went through all this stuff with my wife's honda. Finally I said screw it with her car, I dumped the dunlops I had and went with goodyears which were actually on sale and cheaper than the prorated price on the dunlops!!
I had no problem getting these tires mounted. THey fit nicely on the rims. I run 32 psi up front and 28 psi in the back and have a nice smooth contact area. I have noticed that people with 8" rims and wider wheels run similar pressures.
