No more than 1800 mm-Hg for street riding, depending on the type of riding.
Much lesser so for track, around 1600 mm-Hg.

Adjust for ambient temperature.

It is more relevant to ask what pressure to run for a specific tire than for a specific bike. The specific tire, how much weight it's carrying and what you are doing are more important in determining tire pressure.

If my memory serves me right. Manufacturer spec for my bike is 38 front 42 back. Tire spec is max load and psi, not to exceed?

Yeah, that's max pressure for maximum load capacity. I would never run a sportbike rear tire at 42psi , unless you are carrying a 200lb passenger.:dowhat

Interesting. I have always used what was on the swingarm for street riding. Most tire manufacturers always suggest to use OEM pressures also. It seems strange that they wouldn't give you the recommended standard pressure and max then.

What if you are the 200lb passenger.. :dowhat

Use max psi listed on tire for street riding. Track riding is another story...

I still wouldn't run 42psi..unless your had another 150 lb passenger on there with you.

Why would you want the max PSI if you are not loading the tires to the max load rating? Higher pressure is just going to wear out the center of your tire faster and possibly keep your tires from coming up to optimal temp quickly. I agree you should run higher pressures on the street than the track, but not max psi listed on the tire.

Sorry....failed attempt at sarcasm :laugh

Yeah...on the street I'm more inclined to run 37-38 in the back and 33-34 in the front...obviously I adjust to temps/riding conditions

Keeping your street tires inflated as recommended will reduce wear and prolong the life of the tires. That is because a low pressure, tire gets to a higher temp and wears them much faster. This will give better grip, but for street riding it's not necessary. now if you decide to ride out to the canyons, then by all means drop the PSI *ssome*. It's very rare anyone will push their tires beyond its grip on the street if your doing it right.

For street riding, I guess when in doubt, go with OEM settings and that's 36/42. I'm sure 34/40 would be fine as well. There are many articles written on this that can be found on the internet and almost all point to saying "go with what your manufacturer states unless you are tracking then go lower to give more contact patch and help heat up the tire faster".

If you have them inflated to the max tho, you are going to wear out the middle more because you aren't squishing them down as much (instead of distributing the wear of the throughout a larger section of the tire, you're putting it all in a small band in the middle). If you don't have it loaded to max, you shouldn't have it inflated to max.

You will also be limiting your grip. Since you aren't squishing the tire down because it's inflated so much, you won't have as much surface area of the tire in contact with the pavement.

You will get less life and less grip out of the tire if you have it over-inflated

Dunlop recommends 32 psi front/30 psi rear for the Q3's. Those are the pressures I run on the street and on the track, and I usually get 8K - 10K miles out of a set. Maximum pressure is only for maximum weight. If you run maximum pressures without the extra weight, you are more likely to slide around when braking (especially the rear).
