im runnin a 235/60/14 on a 14"centerline now and it looks kinda small the tire width is good but i would like to go taller 15"preferably

right now i have 235/70-15's on 15x6.5 steels (4.125 bs)

i have about an inch on both sides (rolled lip 1/2") and im getting 15x8's with 4.5 BS so i can use about an 1/8" shim to fit a 28x9 slick under it...

so i would say 255 width 28" tall max
