ET 26 Maybe
I had et 23 on my 18x8 Comps.

225/45 would fit nicely, a lil stretched too.

17X9 front or rear. I run a 17X8.5 with 235/40's et22. No flares, just rolled fenders and stiff springs. no more room up front, i will be going 9.5X17 with 265/35's after fall (s50 conv.) My 9.5's will be either 20, 22, 25, or 30mm offset. Probably leaning towards 20, but all of them will fit. Early e30 rear fender arches ROCK.

I thought the et for a 9" wheel was supposed to 15-20 for a e30.

I'd go for 17x9" et25mm. It may not be enough offset, but it would leave you with the option to run a 5mm (=20mm) or 10mm (=15mm) spacer for any offset you want. If buy an et20mm wheel and it sticks out too far you are screwed!

It doesnt matter how wide the rim is... It's the width of the tire you have to worry about. You can have a lil bit of stretch in the tire.

This pic shows a slightly stretched tire on a 9x16 wheel.

Well, I don't want to split hairs but I can't totally agree. The effective section width of a 215/40/17 tire will be wider on a 9.5" wheel than on a 6" wheel! So, whilest rim/wheel width isn't the only factor, it is important to consider it when choosing the offset.

damn, now i'm more confused....

i remember andre saying with a 16x9 rim with a set offset of et15 he needed to run 10mm spacers making it an et5 ?

You are incorrect.

Guys, if you have an et15mm wheel and you add a 10mm spacer you end up with an et5mm wheel.

This is why I suggested getting et25mm wheels. Spacers are available all the way up to 35mm which would leave you with a -10mm offset....crazy stuff!

Fair enough, but when you want to go maaaaaad phat with crazy wheels there is often some guesswork involved ;)

Seriously though, feel free to PM me for more info, but I'd get either 20mm or 25mm wheels. You can't even notice a 5mm spacer behind the wheels.

i agree with you the owner must be sooo cheap and sooooooo dumb, another dumb ass EUROPEAN, no wonder they made EURO TRIP to make fun of stupid Europeans, why in the world would he put a 215/40 on a 16X9" wheel :confused:

He has those tires because otherwise it will rub.

My position remains the same. I would get a 17x9" with either an et25mm or et20mm and space out from there if nesessary, but it probably won't be.
