Will a 315/35r20 on a 20"x10" fit in the rear?

[softballnrd27]

I am looking for a fat tire and wheel combo for the rear of my truck. I have found a 315/35r20 that is a 27" tall tire, and a 20x10 with 5.5"bs. Do you think it will fit or will i have to widen the tubs?

[Cherub]

that tire will be more than 12" wide

[softballnrd27]

Tire Specs:
Section Width 12.6" on an 11" rim. Rec rim- 10.5-12.5"
28.7" tall not 27"
I think it will be close, I read on here somewhere that they had this size tire on a 20x10 and it was close but they don't say if they modified the tubs or anything.

It will fit. I'm running a 20x12 w/6" bs. with a 315/35/20 lowered with a flip kit. I had to trim the fender lip about 1/2"
Just get your backspacing perfect!!

I had 295-40's on 20x10 TT2's w/5.00"bs & then some Coy's w/5.50"bs w/approx 8" of rear drop . The 5.50"bs put the 295's pretty close to the inner tub wall. The 315's would come even closer since they are dimensionally wider but would still prob clear. I would imagine they would rub occassionally & you could always run a small .250" spacer to help (the 5.00"bs is ideal).

IMO, 315's need an 11" wheel minimum.

I have been thinking of a 20x12 as well but those wheels(Vintec) are a little more expensive than I wanted to spend. I really want the Vintec soft lip dish in 20x12 and 20x8.5 so i am probably going to just wait a little bit longer and get the wheels I really want. I am looking at the Eagle 225s that are a little cheaper but I don't like them as much as the Vintecs. I am not against adding some width to the tubs but I would like to keep the rear-end at a stock length. I will just have to wait until I get home and do some measuring to see what I can fit.

I'm currently running a 295/40/20 on 20x10 Boss 338s. I'm lowering the rig another 2 inches which will bring me down to 7.5 in the rear. I'll have to run a spaced and extended studs, shave the inside of the bed and inside of my fender to fit a 305/35...good luck Bro.

I am going to save for some 20x8.5 and 20x12 Billet Specialties SL Dish Vintecs.

I need to see some pics of your set up, I am planning the same for mine

How much did you have to space out the Boss 338 20x10's to work in the rear?

Stock C10 10 bolt?


Thanks!!

The Boss is 6.25" BS if I remember right. Showwheels have a 5.5" rear backspace, and we are running a special for April (10% Off).

mmmmm very tempting

I already bought my Boss 338's for another project, or I'd be all over them.

Right on..... should look good on the truck, just need that spacer. The 305 & 315 look killer on these trucks.

I originally went with 275/40/20's on my Boss 338's, but they were bald within a year. I didn't like the tire stretched look anyway. I am using a set of 1.25" thick billet spacer/adapters to center the wheel in the housing and get the effective backspacing to 5.0".

Just bought a pair of 315/35/20's. They are mounted, balanced, and on the truck now. Looks like I might be rolling and/or trimming the inter lips to clear when hitting bumps. The truck is down until I complete the turbo setup. I thought about getting a set of 1.0" billet spacer/adapters in order to 'suck' the wheel closer under the truck since I have more room to move inside.
