On a regular basis, check your tires all around. Rotate tires completely and make sure there are no objects penetrating them. If you find anything, do not ride until you have your motorcycle dealer inspect the tire and replace it if necessary.
Check the sidewalls for signs of cracking and never use sidewall treatments or dressings, which can actually accelerate tire cracking.
Checking tire pressure is the most important maintenance function you can perform. Maintaining correct air pressure is crucial to rolling efficiency, steering, grip, wear and load-carrying capabilities—for every 4 psi a tire is underinflated, you could lose up to 80 pounds of load-carrying capacity.
You're not only riding on your tires, you're also riding on the air in them, so check cold air pressure as often as possible with a high-quality air-pressure gauge, and have it calibrated once a year.
If storing your motorcycle for the winter and/or storing spare tires, try to avoid frequent extremes of temperature. Don't keep tires next to sources of heat; they'll age more quickly.
Don't store tires where electric motors are present; high concentrations of ozone will accelerate tire cracking.
Make sure you select tires that can carry your expected load, including the total weight of the motorcycle, the rider(s), luggage and any equipment. Always match front and rear tires.
After installation of new tires, make sure the arrows on the sidewall are pointing in the correct direction of rotation, and that the balance dot on the tire is lined up with the valve stem.
