18X8.5 ET 30, spacer ?

pittsy · 10-14-2008, 09:40 PM

Do I need spacers on the rear?? I know the front is ET29 so 30 is almost perfect but the rear is ET23, will that require a spacer?

Winter set up?

10mm in the rear with 18 x 8.5 et30 should work well. Don't forget the longer bolts.

i don't think it won't work, but if you want it to look good get a spacer

no winter set-up, just a set i have that i want to put on the car. Also, what is the biggest tire you can fit over an 8.5?

I wouldn't recommend running something that narrow in the back, but I'd space an 8.5 +30 at least 15mm on my own car. The problem is, you're getting into bolt on spacer territory at that point, and many people aren't comfortable with running bolt ons.

I'd run no more than a 255 width tire on an 8.5" wheel.

^ Agreed. If you just simply want to push them out a bit then 10mm is fine but you could run up to about 20mm+ if you like.
