Ok...after reading all the good info on tire fitment in this forum, I think it be best for me to go with a 305/55R20 (If I did my math thats = to 33x12x20?).

I currently have 275/55R20 on a 20x9.5 rims with approx 5.5 to 6 inch BS....this setup gives me roughly 1 1/4 inch space between 275's inner wall and upper control arm.

The 305/55's should fit ok right? Shouldn't rub upper control arm should it?


Only Tire I found in a 305/55 R20 are the NITTO TG and the Micky Thomson AT....anyone know of more in this size?

 

heres a few
bfg,nitto tera grapler,toyo open country a/t,cooper zeon ltz

the cooper zeon ltz is a really good looking tire and is only offered at discount tire i think

hope this helps

 

I believe the Mickey Thompson ATZ and Pro Comp Xtreme AT are also available in 305/55-20.

 

Hey Wandell...so is a 305/55R20 same as a 33x12.50X20??

 

That is correct! I will be going with 305/55/20 Nitto TG AT's soon.

 

actually the 305/50/20 is the 33x12.50x20
the 305/55 is slightly taller

 

305/55/20 is only 12" wide.

 

305/55/20 Cooper Zeon LTZ

 

305/55/20 Nitto TG's on 8.5" wheels. Not sure on backspacing but there is no rubbing. I do have the AS leveling kit up front.

 

A 305/50-20 is approximately a 32x12.50 tire. A 305/55-20 is approximately a 33x12.50 tire. If you want the exact height and width, look at the manufacturer's websites.

 

Moveqik....Nitto's looks nice!! do you think you couldve went with a 33x13.50 R20?

 

Thanks! Opinions may vary but I don't think I could go any bigger with the wheels that I have. I'm certainly not the expert so other wheels may net you a different result.

My wheels are 20x8.5 MB Yuma's. You can check with Discount on the offset if that would help.

 

Hey moveqik,

What's the backspacing on your wheels? I'm looking at some new wheels and the ones I want are 20x8.5 with 6" of backspace. I want to make sure that those will fit on 305/55/20 Nitto TG's with my AS 2.5" leveling kit.

 

Again....not sure about the backspacing. Sorry! They are MB Yuma's from Discount. I would check with them. They should know.
