Speaking of trailer tires, what pressures are recommended for them?  Do you
use the max pressure stamped on the sidewall?  I bought a used trailer and
the tire pressures were all under 30 psi.  I raised the pressures, but still
not to the max stamped on the tires.  It is a two-axle open car hauler.
Race car plus trailer probably weighs around 4000 lbs.

Also, the tires on the axle which has the brakes have a cupped wear pattern
on them.  What causes this?  On a car this usually indicates bad shocks, but
the trailer has no shocks.  Maybe the tires are bouncing under braking?

Thanks,
Brad Burns
