for my 92-95 civic, its 35 mm. But here is how you can figure out your needs. I used the www.discounttire.com site. I did a seach for new wheels for a specific model. The orig and opt. wheel size choices will be shown. Then select a size. The search returns will show size in diameter, width and offset. www.tirerack.com has some info on wheel tech if you need some tech details explained.
