| Re: Re: How does front tire width affect car characteristics? Quote:
Now how about this A car with an 8" and 8.5"rear setup ran fine and was balanced in and out of a turn. Now the driver got new wheels in the back and is now running a 8" and 10" in the back. Since the rear traction patch is larger it will slide less and will hold a desired line in and out of a turn, however there is no change up front, therefore causing the car to understeer. Is this neccesarily true?

| Ya I thought of that, its bad enough with 195's up front with no power steering. On the chart that Postmaster posted under the E30 link, it said that the more downforce through aerodynamic adjustment in the front will lead to understeer and the more downforce on the rear will lead to oversteer. I thought the exact opposite ![]()

| I run 255/35/18's on 18x9's up front w/ 12mm spacers. That's A LOT more width/track than stock 225's on a 7.5" rim. Wider is better. Handling is phenomenal for a street car. Great turn-in, precision, feel, etc. No downside, except for increased tram-lining and bump-steer on bad roads. |

| If ur talkin about street tires... I run a 205-50 on the front of my 02 and a 225-50 on the rear.. same setup for hoosiers and autox.. works great.. the steering is a bit heavy but no toe helps..... the track car sits on some nice 0 offset zender 15x8's... deep dish.. with what would be like I guess a street tire 245-50 sized race slick on it.. once moving the car handles well.. I don't see why you need a 10" wide tire in the back.. even with 220+HP in this 4 cylinder it's hard to generate rear traction issues

| I got my 215/50/15 a month ago and im really happy with it. braking is better and response too. Also its a better match up with my 225/50/15 rears and with my new adjustable front coilovers, it fills the fender gap A LOT better than my 195's. Also my front is not dropped anymore so there is less weight there at level sitting. Thanks guys, this thread helped. Im not really going to have 10" rims in the back, i just used that as an example.
