Ever wonder what the best tire pressure for your bike is. Obviously everyone doesn't ride the same, weigh the same and always go out when its 75 degrees and sunny, so how could the same pressure work for all of us, all the time? There are way to many variables to pinpoint a specific pressure thats perfect for every one here.

so what the heck are we supposed to do? Question Question

Idea OK, the easiest way to find the proper pressure (no, its not looking on every site asking 'experts') is to do the following.

1. set the tire pressure at both ends to the factory recomended level.(36fr 42 rr on 95 YZF600 not sure on later bikes but prolly the same) as a baseline.

2. Go out and ride the bike as you normally ride for about 45 minutes.

3. Pull over and immediately check the pressure, using the same guage that you used for the baseline setting.

4. Do a little math...the 'hot' pressure should be as close to 10% greater than the cold pressure as possible. This will give the best life/performance combination possible for your bike/tire/riding style.

If your pressure rises more than 10% from cold try adding 1-2 psi pressure. if it rises less than 10 drop a pound or so.

Remember, this only works when comparing cold to hot but spending a day heat cycling the tires aint a bad way to go (park in shady area and it will take about 1 hr for tires to cool.)

!0% is prolly the best overall compromise with pressures that you will find.
gains as much as 15% will work great for extra grip but tire life will suffer way more than grip improves. for track days go somewhere betwen 20-25% gain (all above based on real world experience and tech seminars with tire reps.)By testing for the magic 10% in a variety of conditions you will quickly find a setup that works for you and whatever type of riding you plan to do that day.
