245 is the maximum recommended size for a 7" rim. I'm running 235/60 on the front of mine.

Actually 255 is the max recommended for a 15X7" rim in a 60 series. That's what I got on my rear, but my front's are 14X6 with 70 series 225's which works out to the same 26" diameter.
This is my long winded way of saying the 15", 60 series, 245's will work up front.
