Try these......

Scotti when u you mean scrub line issues i assume your talking about the trailing arm now sitting lower due to the blocks, and the arm possibly rubbing on the ground.

My question is what in the world does wheel diameter have to due with it. Don't u mean overall tire diameter?

Example; I run 16 inch rims w/ 235/85 tires ....31.7 inches in diameter!!!!

Most 18 inch wheels w/low profile tires (35-40 series) are now where near that
tall ....It all has to do with aspect ratio of the tire. Even a 70 series 15 inch wheel tire would be close if not taller than lets say a 40 series 18 inch wheel

Wheels are solid material so the OD of the wheel does not change in the event of a flat. A 29" tall tire on the other hand can go flat winding up much shorter thus making that wheel diameter the one thing that keeps you above the scrub-line.

Got it Scoti ....wasn't taking in the account of the flat tire scenario ........

"if it aint broken ....break it ....then you have an excuse to mess with it"
