What tire size should i get on a 17x8 wheels? Recommended tire size is 215/45/17 and i'm thinking i want a little more rubber on the tire and so i figured 225/45/17.
Thoughts on this? __________________ 98 Avus Blue 318 ti Active

Keith,
I would recommend 225/45/17 or 235/40/ 17 for two reasons; contact patch and rim protection (I run 225/40/18 for the street and for the track 235/40/17). Although with 215/45/17 you might not have to roll the rear quarter lip now that your dropping the ride height.
Btw, did you decide on any wheels?

Thoughts on this? | I have the 225/45/17s on 17x8s. They don't rub and I don't have rolled fenders. __________________

So with 225's i'm gonna have to worry about rubbing on the fenders depending on the offset? The OZ wheel is a 40mm offset. __________________ 98 Avus Blue 318 ti Active

Different tires have different tread and section widths although they are the same size; ex: 225/40/18 Dunlop Sp Sport 9000 has a 9.1" section width. A Conti Sport Contact 2 has a 8.9" section width for the same size tire. Tirerack has all this info when you look at the tire specs. I belive the BFs are 8.9 for 225/45/17. It also depends on the ride height (springs) you install. Cheers, __________________

If you go with the 235/40/17s do you have to roll the fenders for sure? | | | | | 03-07-2006, 08:58 PM | #9 | | Senior Member Join Date: Apr 2005 Location: Great White North! Posts: 701 |

I have 215/45/17 in the front and 235/45/17 in the rear
and my fenders aren't rolled, and i get no rubbing. | | | | | 03-14-2006, 03:14 AM | #11 | | Junior Member Join Date: Aug 2004 Location: Oklahoma Posts: 21 |
I am running 225/45/17 all around on 17x8 40mm offset. I got a good deal on the set, but really like how the tires feel.(no rubbing for me) Next time I plan to get some 235/40/17, only for a wider look. | | | | | 03-14-2006, 03:27 AM | #12 | | Senior Member Join Date: Dec 2004 Location: Muncie, Indiana Posts: 1,551 |
I have 215/40/17 on an 8.5 inch wide rime with a 42 mm offset and 12mm spacers. With a 2.5 inch drop there was no rubbing, but after going to 3.1 I had to roll both front and rear fenders. | | | | |
