NOTE:
Wheel-to-hub optimization is important. Clearance between
the wheel and hub can be used to offset or neutralize the Road Force® or
run-out of the wheel and tire assembly. For every 0.001 inch of
wheel-to-hub clearance, the Road Force® can be affected between 1 and 3
pounds depending on the tire stiffness...
