TIRE PRESSURE

Check

sidewall

of

tire

for

manufacturer’s

recommend­

ed maximum tire pressure. If this information does not

appear on your tire, maximum tire pressure under any

circumstances

is

30

p.s.i.

Equal

pressure

should

be

maintained on both tires.

INSTALLATION OF TIRE TO RIM
