Tire Size for my wheels ....

[OffTheEdge]

I just put on some M-pars, used my old tires since they have at least 75% tread left but I don't like the fact that the rears (265/35 18 on 9.5s) roll in and the fronts (245/40 18 on 8's) are square and taller than the rear. After hours of research, I came up with this combo ..... 275/35 rear and 235/40 front. they will both have same O.D. and should have the same roll off the rim edge so does anyone else have this setup?

tires now, I don't like the look of the front being taller.

The 235/40R17 front would actually be a little shorter than the rear 275/35R18. BMW would actually match the 275/35R18 with the 245/40R18 on the front.

Thanks for the response. After calling Continental they gave me some direction. They actually said the same as you if i go with 275/35's on the rear but I decided I'm keeping my 265/35s on the rear and putting 225/40's on the front. the rear is 25.3 O.D. and the front will be 25.1 O.D. Plus they will have the same profile and roll in on the lip. that was I can lower the car with no issues.
