Man, I love having my own tire machine! LOL I've got a set of 245's on 7" wide rims. BTW, for those looking for the ultimate tire combination and don't mind a little modding to get them to fit- 245/45/16 on SSR GT1's

. 5mm spacer and fender rolling required in the rear and no mods needed up front. Talk about putting some meat on the ground.
BTW, I use a little bit of armor all on the beads to get them sealed up. Worst trouble I've had was 235/35/17's to get mounted up. IIRC we had about 55-60 PSI getting the bead to seat up, also use a rubber mallet on the sidewall lightly to get the bead to slide a little since it's just friction holding it in place and a good bump will get it moving the right way.
