20x10 -12 in 35/12.5r20 M/Ts on a 6" Lift.
Same rims in 275/60r20 A/Ts on 2" level.
Shop initially installed 305/55r20 A/Ts when I first did the level. Fronts rubbed lower valance, crash bar, and oem mud guard that's why I made them go back to stock size. With the 6" lift, rubbed the lower valance (that was already cut to accommodate the 275s) so I did the active air dam delete and trimmed off the lower 1.5" trim of the valance. Still rubs the corner valance or the mud guard when reversing during hard braking.
