How to ensure your tires are properly inflated
Start with the motorcycle manufacturer's recommended
pressures. Do not exceed the tire manufacturer's recommended pressure. That
value is printed on the sidewall. Now that you have your boundaries, I recommend
using the 10% rule to dial in the correct pressure for your riding style and
your bike. Consistently using the same tire pressure gauge which you have deemed
reasonably accurate, check your tire pressures when they are cold. After you
have ridden a bit and have gotten them up to temperature, one of your normal
rides, stop and immediately check the tire pressures. Don't wait too long after
you stop to take the readings. Do it before you even take off your helmet.
If your cold tire pressure was correct, your hot tire pressure will be
approximately 10% higher than your cold tire pressure. If your hot tire pressure
is more than 10% higher than your cold tire pressure, that means your side walls
are flexing too much because your cold tire pressure is too low. If your hot
tire pressure is less than 10% higher than your cold tire pressure, that means
your side walls are not flexing enough because your cold tire pressure is too
high. Next time your tires are cold, make the necessary adjustments and repeat
the exercise. The results will vary depending on whether you are riding solo,
two up, solo with gear, interstate or twisties, summer or winter, high altitude
or sea level. Eventually you will end up with a reference log for the different
conditions.
If you do this, you will optimize the combination of tire life, performance and
gas mileage.
