What are the largest diameter wheels that can fit a 2005 STI? I'm looking to do 18"x8.5" (17"x8" is stock).

Then, I want to put on a wider tire... but still keep the overall tire "diameter" the same with a lower profile tire.

Any suggestions?
=============
This is assuming no rubbing issues.....
=============
that shouldn't be a problem.

If you wanted to roll the rears you could fit a 18x9.5 with a 255/35 assuming your car isnt slammed and has a bit on camber. Some people seem to be able to fit these with no fender mods at all, and some need some help
=============
i have 18x8.5 +48 with 255/35/18s on my 04 with rce yellows and no problems. a slight rear fender roll was all i needed. clearance with the strut is about 1-2mm at most though :)

I have 18"x8.5 with a 245 tire on my 04 sti....it rubs when i take corners in the rear only if i have 3 ppl sitting in the back. other than that its great

Just so you dont become anymore confused...........stock sti rims are 17x7.5 NOT 17x8

I'm not so sure.... I was told they are 17x8 for the 2005 model year.

2004 STi has 17x7?

2005+ STi has 17x8.

My 2004 STi is running 17x8?with 245/40-17.

Anyone know if you can fit a 235 series without rubbing? Looking at 235/40/18 Dunlop Direzza Star Specs, just want to be sure I won't have any rubbing issues before I buy the tires.
=============
I just got back from a track day. Guys with Sti's are running 275's. Wow, did that look good. Are they using special deep dish wheels to fit?
=============
on a 18x8.5 rim with a mild offset, you'll do just fine with a 235 or 245 tire.

How can you go wider than 245, without a lot of major surgery?
=============
do you need anything larger than 245?
=============
Yes....... for the track. I have 225's now and they seem grossly inadequate. Some of the Evo and STi guys are running 275 and 285's. I know. . . . way to large for my needs.... BUT, I'd like to get MORE than 245.

Nice. I think I saw something like that downtown last week.

I run an 18x9 with 265/35/18 rubber and dont rub, with minor modifications.
=============
what's your suspension setup?
what are your alignment settings?

Those two factors significantly determine what size you can run.
