Tubeless tires have some degree of self-sealing ability if they are punctured.
However, because leakage is often very slow, you should look closely for
punctures whenever a tire is not fully inflated.
Always check air pressure when your tires are "cold"
has been parked for at least three hours. If you check air pressure when your
tires are "warm'' even if your motorcycle has only been ridden for a few
miles the readings will be higher. If you let air out of warm tires to match the
-
recommended cold pressures, the tires will be underinflated.
The recommended "cold" tire pressures are:
front
rear
Refer to Safety Precautions on page 72
Whenever you check the tire pressures, you should also look for:
Bumps or bulges in the side of the tire or the tread. Replace any tire that has a
bump or bulge.
Cuts, slits, or cracks in the tires.
Replace the tire if you can see fabric or cord.
Nails or other foreign objects embedded in the side of the tire or tread.
Excessive tread wear.
