I don't have lugnuts yet, so I couldn't put the car down...
18x10.5 +15 RPF-1 (19 pounds!)
285/30/18 Hoosier A6
Rear fenders rolled and pulled lightly, -2* camber
Front fenders pulled lightly (not much to roll), -3* camber
Pictures are at full droop on the lift.

People have these same wheels on street tires fitting... so I think they'll be OK.
I am planning on raising the front though. There's not enough room for larger bumps on my street tires, these will hit the fender liners or fenders for sure.
