• Check condition of wheels and
rims. Especially look for cracks,

inflated, no serious cuts, bulges,
tread wear or any signs of
misalignment; valve stems not
touching wheels, rims or brake
drums; valve caps in place and
no objects stuck between the

no obvious leaking on outside or
inside wheel.
Suspension
• Check condition of springs (leaf
or air), spring hangers, shackles
