I used to but I don't have any good pictures to show how "skinny" they are.....on a 7.5" rim, a 235/40 tire is REALLY beefy

The Volks I just got are 18 by 7.5 with 235 tires and I think its just the right amount of rim protection.

By contrast my 18 rs4 reps are 8.5 running 235's. and are Just the right amount of stretch to maximize the tire.

235's on 8.5's. Dont have very good pics, but you can see how it fills out the rear very well..

lol, he will get what he wants.. If he wants to fill out and make it flush, well that is why they make spacers. I have a pic of my 7.5 wheels somewhere, ill dig it up.

yes spacers will prob be ordered later on. it is a 2.8 tip so its not a huge performance machine and i dont NEED more tire on the road per say :( and i did just pick up a dedicated auto x car,

Don't the skinnier wheels usually have a lower offset to have it stick out the right amount?

The 7.5's in my thread have a et30 and they sit just about flush with the fenders.

JaVa

these are et35 still, but the back spacing is diff.

andyrew
01-19-2009, 09:19 PM
So you'll need a 5mm spacer to get the ET30 backset.

^^ your not doing it right. Yes it will be an et30 rim, but 18x7.5 et 30 and 18x8 et30 will fit completely different. The 18x8 rim will stick out 6mm more and will be in 6mm farther. Your 18x8.5 et35 will stick out 8mm farther then the 18x7.5 et 30.. He will need about 15mm spacer to get it somewhat flush.

JaVa

well it depends on the backspaceing on the diff rims

^^ the "back spacing" as you call it is really the "offset".

edit: maybe this will help you out, should help you understand things a bit more.

so here is waht tire rack says for the 18x8.5
Offset: 35mm

Backspacing: 6.18"
Bolt Pattern: 5-112


and the 18x7.5
Offset: 35mm

Backspacing: 5.70"
Bolt Pattern: 5-112

Yes, because one rim is 8.5" wide and the other 7.5" wide, which is why they are different. It is referring to your inner clearance, which changes with diff. width wheels and offsets. Obviously the 7.5 will have a bit more space since it is a skinnier rim. You can't "change the backspacing" of the rim without changing either the width or offset. I wouldn't pay attention to the "backspacing" simply because all you need to knwo is the width and offset. That will tell you exactly where the rim will sit.

Make sense?
