It was recommnded to me to go with 245x60x15 on the front and 255x60x15 on the back. The 255x60x15s fill out the rear wheel well very nicely with plenty of clearance. Haven't gotten the 245x60x15s on the front yet but they look very nice on the 8" snowflakes. Since they are a bit smaller I'm not expecting to have any clearance issues.
btw - BFG TA Radials all around.
