yea i seen the options of 3.5 4.5 and 5.5 and i had no idea

 

yep 5.5 is it.... for the back

 

ight thanks again for tclearing that up

 

the back spacing means the distance from the inside of the rim where it mounts to the hub to the inside lip of the rim. If a 9" wide rim with a 5.5 backspace fits just right, if you want a 8" wide rim, you will need a 5" backspace for it to fit the same as the 9" with a 5.5, or a 8" with a 5.5" backspace with a 1/2" spacer. If you ran the 8" rim with a 3.5" backspacing, you will have 4.5" of rim past the hub where you should try and keep it around 3"...you would have issues.

 

ok damn man u bout had me lost there lol . but went and checked my wheels and thought they were 5.5 but they dont look that deep . so does that mean my wheels prob 15x8's and would a 265-50 fit on 8" rim ? thought for sure mine were prob 9's but now said all that and looked at mine think maybe they are 8 's i dont know ...

 

that tire will fit on a stock rim...so an 8" is a no brainer....alot of guy do as follows

15 x 8 x 5.5" bs
15 x 9 x 6.0" bs
15 x 10 x 6.5bs

 

If guys are running 275/50/15 on a 7" rim, you can surly get 265/50/? on an 8" rim

Sorry, I got carried away..LOL

 

well i know damn good in well mine arent 7" wheels lol . cause they dont make a deep dish 7 " wide wheel so i know its least 8 or 9 hell i dont know im gonna take one off tomorrow and check to see what says on back . and damn a 7 " wide wheel with a 275-50 wow thats gotta look fckd up lol. tire would be like 3 times size of the wheel ...
