I've decided after a previous post I made to not go with 275s on the front of my car. However I'm going to be getting 9" wide rims for the front. I don't want the tire to appear "stretched" so I was thinking of going with the 255/40s instead of the 245/45s. The only problem I see with this is a 245/45/17 is 25.7" in diameter, and the 255/40 would be 25.0". I'm running 315/35/17s in the back which are also 25.7". Would running a smaller diameter tire in the front throw anything off? (Like ABS) Or would it look weird?
