    18x9 Tire Size

    Hi all,

    I have asked before about running into any issues with a 245/35/18 and that seems to be ok. I'm 98% sure that I will be buying Super Sports for them. That being said, which is preferable? 245/35/18 or 255? I'm wondering what the pros/cons will be with these sizes.

    They will be on a square set of Apex EC-7 et 42.

    Thanks!

    I would do a 245/35/18 unless you want more tire up front.

    I'm very happy with my 245/35/18 square with SS. Not sure of the pros/cons of the 255s but they fit. I guess 1 con is the price on the 255s w/b higher.

    18x9 Tire Size

    On a 9" wheel? I would probably run 255 minimum. I'm running 245 on a 8" wheel
