what is the correct tire pressure for a M750 monster?  I weigh 210lbs.  I was reading that you shouldnt go by whats on the tires.

It really depends on how you ride. If you don't ride the bike too hard, and you'd like a little more life out of your tires, try 40 front/40 rear.

Generally as you lower pressure, tires get hotter and stickier. This is of course within reason, when you go too low, the sidewall will fold, and you'll have all kinds of issues. The downside to this is that stickier tires leave a lot more rubber stuck to the road, so tread life can go down dramatically.

I usually run 38/36 or so.

There's not good answer, since each tire manufacturer does things a little differently.  What might be a good pressure for one tire might be too low for another etc etc.  Most manufacturer will have the recommended pressures listed some place.  Some have different pressure specs for track vs street vs whatever.  So I'd go hunting around the tire manufactures web site

Why wouldn't you go by what's on the tires?  I would hope that the tire makers aren't just putting crap on their tires for the fun of it.  But, the numbers on the tires are probably the maximum pressure rating, as opposed to 'optimal' pressure for performance/traction that you're probably looking for

i've got a '00 M750 and i run about 32lb front , 34-35lb in rear.

The numbers on the tire sidewall are for max inflation...not recommended inflation.

That pressure is determined by the vehicle manufacturer...same for cars.

Ducati recommends 32 front 34 rear for Monsters.

+1 on dp's comments

probably the best thing for you to do is start at the recommended settings and then go up or down and see what feels right for you and your style of riding.

I run my 750 at 32.5/36.5

I'm with Yuu on this one.  Tire pressure depends on the tire you have on the bike.  Michellin Pilot Powers have a recommended tire pressure of 36 front and 36 rear.   Their pilot power race tires are 32 front 22 rear (huge difference).

Take a look at what tires you have on there now, see the max PSI for that tire and try the recommended setting and go out for a spin.

Remember, always set your tire pressure with COLD tires.

I have been trying different pressures and I am good at 33front (pot holes where I live) and 36 rear I am at 6500 miles on my current set of tires my rear is just starting to go bald down the center. The front looks fine lots of tread left

thanks guys, ive been running 34 front 32 rear, just checking to make sure.

Where did you get that info?

I called Michelin and asked for their recommended pressure and they specifically said they had none and to use Ducati recommended pressures for the street.

Also my Michelin guy says 30 for a power race.

I run 32front/34 rear though, i dont know the correlation between PSI and tread/traction.

Im assuming the trend is.

Higher pressure = less tread wear, but less grip
Lower pressure = more tread wear, but more grip

Now, for say a sport tire such as a Pilot Power, ive heard 32 is the lowest you want to go while maximizing tread life and grip. So  from 32psi to 33psi, to 34,psi, to 35psi, and up, whats the percent increase of tread life when my riding is consistent?,

I got that from the West Coast Michellin rep.  Now, I'm didn't ask them "What is the recommended tire pressure for a 2007 Ducati Monster? when using the Pilot Powers and or the Pilot Race tires?"

So take that for what it's worth.

from the 2007 s4r shop manual

Front Tyre pressure (Cold) 2.1 bar - 2.3 kg/cm2

Rear Tyre pressure Cold 2.2 bar - 2.4 kg/cm2

Same info is found on the maintenance manual, now if someone could tell me just what that means I'll be a happier person 

1 bar = 14.7 psi

So, 2.1 bar is 30.9 psi
2.2 bar is 32.3 psi
