Hey guys

I've been on this site for a few months and finally registered, now I just need a digital camera! Anyhow I have an '05 FX4 SCAB with a 2.5" leveling kit. I want to run some 20's with an AT tire. What is a good setup (sizes, backspacing, etc.) that doesn't require cutting or trimming. I've been trying to figure it out from reading stuff on the net but thought I'd just ask someone who knows! Thanks!!!

 

On my '04 SCAB I have had 305/50/20 on 10x20 rims and now have 305/55/20
on the same rim. They both rub at full turn in reverse on the lower end of the fender flare. I didn't do any trimming. I have a 2.5" AS leveling kit with Nitto terra's and I think it's the perfect fit. When you get them send some pic's.

I'd go with a set of 305/55-20's (33x12.50) on a set of 20x9 inch wheels with 5 to 6 inches of backspacing.

 

I agree. Thats your best bet.

 

thanks for the replies guys! i think i've decided on black kmc rockstars, but do i get the 20x8.5 or 20x10? what are the advantages/disadvantages of the sizing and what backspacing should be used on either application. i think also i'm gonna go with a 305/55/20 nitto terra any other tire suggestions? thanks in advance......you guys are great!

 

What is the backspacing on the two sizes?
