Im doing a lift on my 2500HD pickup, 3" in front and 2" in the back. Will Nitto 315 75 R16's fit on it? they come out to a diameter of 34.5".

 

What year? My 03' has a 6" lift and the 325/65-18's (34.5's) still rub the back of the fender opening when the tires are turned and hit a bump just right. It also depends on the width of the rim, mine are 10" wide, on a 8" wide rim you might make it, it's gonna be close.

 

it's a brand new 05 2500HD. It's a 8" wide rim. I'm hoping to maybee get about 3 1/2" out of the front key locks im doing. It's gonna be close i know.

 

It all depends on the backspacing of your rims...anything less than 5 inches and your going to be moving the bumper forward or trimming it. My buddy has a '01 2500HD with "green" keys and a 2" block out back...this morning we mounted some 315's on 16x7 with 4.5" backspacing, .....no go unless he moved or cut his bumper...now if they were on the factory rims or say a H2 wheel he would have cleared them no problem...as of now he's running 295/75-16's with just the airdam trimmed. As far as getting 3.5" out of keys...yeah it can be done, but make an appointment now with your dentist and chiropractor cause she's a gonna ride like a brick.

 

My wheels are 16X8's with 4" backspacing, Im gonna get the most out of the keys up front and it will ride like crap. Ive had to trim on my last 2 trucks with 295 nitto's with just the torsion bars cranked up. Im guessing i will end up cutting a little fender and it wont be the best ride in the world, but im only 18 and it doesnt bother me.
