What tire size for 17x7.5 wheel? -

M3Fanatic · 11-07-2008, 03:42 PM

I want to get front tires for my E36 M3 and was wondering what size tires to get. From the factory the front 17x7.5s are fitted with 225/45s and I was wondering if it would be okay to fit 235/40s. Tirerack does say that 235/40s on 17s should be fitted on 8-9.5 wide wheels, but do you guys think it will be okay for 7.5s?

Thanks in advance

I have 235's on my 7.5's. No problems.

235 will be fine. Slight bulge though. 225 will look great on a 7.5 Have you checked to see the true section width? Some "235" tires really are more like a "225" from other manufacturers...

I currently have 225/40 and they do look great but I would like some more grip upfront.

Tirerack says the section width is 9.5

Will I be fine, or should I just do 225/45?

I've got Yoko Advans on my 7.5's and they look perfect. No bulge. Section width is 9.6
I say go for it. You'll be fine IMO.

edit - just noticed there's a big difference in the tire's tread width which will affect how it looks, but I still say you'll fit fine.

Good to hear, I'm going with the Eagle F1s though.
Thanks guys

i would suggest staying with 225s, but getting the stickiest compound you can live with/afford. that will take you further than and extra 10 mm of width.

+1. The 235 should work fine but it's not really going to buy you much in terms of contact patch.

235/40 all around

Any reason? If you're looking for more grip look into better tires. The Neovas that were linked are very good. So are Dunlop Z1s, Bridgestone RE-01R, Falken RT-615, Kumho XS, and Michelin PS2.

I hope you plan to match the brand of tires in the rear.

235/40-17 is the stock size on '95 M3's with thier 7.5" rim.

+1, I have Eagle F1's on the R right now, and they are a good tire, they give good dry grip, very good wet grip, but they are pretty expensive, and they have soft side walls. I need a new set of tires soon, and i'm going to be switching to the Dunlop Direzza Z1 Star spec's.
