Post your wheel and tire combos.

REAR: 255/60/R15, BS 4.25(?)

I don't see getting any bigger.
I have the air shocks up as far as it takes to keep them from rubbing (and of course they still do on occasion). I would like to put a set of slicks on the back (keeping the S/S rims), any idea as to the max size to keep them under the wheel wells? I can get a good deal on a set of GY in 26.5x10x15......what do you all think about that size? Like to keep them tucked inside the wheel wells and let the shocks down some.

FRONT: 235/60/R15, I am assuming the BS is 4.25 on all 4. They rub on the right front a little sometimes.
