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
I run 38/36 in my Diablo Corsa 3. Tryed 35 up front the day and that was okay. Didn't notice a differance.
I want to run more in the back but they end up feeling squimy around 40 so I just leave it at 38. It's getting squared up.

Thanks! That's some mighty low tire pressure, I don't even run that on the track!

You should try it.
Tire life isn't optimal, but traction is.
Depends on the tires too.
I run 31/33 F/R with my diablos, but I'm about 160# without gear, on pretty good roads.
People seem to like running the Pilot Powers higher, which makes sense as they're a pretty light carcass.

If 32/34 is higher, then I agree.
36 front and rear, it seems to work fine and is easy to remember.
32/34 on mine. [thumbsup]

that's what my suspension guru set me up with for street riding. i got no complaints with grip, compliance and mileage.
I was using the pressure that is stated in my 07 S2R owners manual.
2.1bar up front (+.3bar to handle rough/bumpy roads) or 35.3psi and 2.2bar or 32.3psi for the rear.
Then I noticed that on the frame there is this silver sticker. [roll] What do ya know! The front and rear tire pressures are listed on it. :o
32.7psi front and 36.9psi rear
If this is like its four wheel brethern. That sticker lists the recommended pressure for the tires that came on the bike when it left the factory.
It is more recent than the manual.
So, if your bike is new look at that sticker.
If your bike is an older model, and the sticker is still on the frame, then you can use it as a reference point. Since you probably don't have the same tires on now that came with it. If that sticker is long gone, well, there is always the owners manual.
As a rule I don't go higher than 3psi less than the max cold pressure,
What ever pressure you use just make sure it is not more than the max cold pressure on the side of the tire.
Hope this helps

That's what I'm running now and the thing is on rails. I think I'll try the lower pressure and see how it feels, if I don't like it I'll go back to 36/36.
Also, this is the first Monster I've owned so forgive my ignorance, but this is the first time I've heard of a lower front tire pressure then the rear tire pressure.
Since the steering is handled by the front wheel, you want that the tire in the front slightly harder to do all the tracking and steering and the rear softer so you can get better grip/drive out of corners.
At least that's what I've run on my R1 when using Bridgestone's or Dunlops on the track.
What's the adjustment for weight generally? Say for someone around oh 130-135 pounds... with gear.....
After thinking about this post I decided to go halfway between the recommended range which equates to 37 psi for the front and 42 psi for the back on Stradas. I'll see how the bike feels, since I don't take it to the track I think it will be fine.
So I went out this morning to the local canyons and tried the recommended tire pressure. 31pst front and 32psi rear (as listed on the frame of my bike). The bike is on Michelin Pilot Powers.
In short, lowering the pressure caused my bike feel really bumpy. Places that I didn't know had bumps because very apparent. It seems that suspension was doing more work then normal so I'm not sure I dig the "recommended" PSI.
I'll be setting the pressure back to 36F/36R and take it out again and see if I'm imagining things or if indeed the lower psi had that much of an effect on the bike.
If it did have that effect, I don't like it. Recommended or not. [drink]

Afterwork I headed up to the local canyons to test out the bike running the higher PSI on my Pilot Powers and sure enough, all the bumpiness and cadillac suspension feelings I experienced on Sunday were all gone.
Now, I realize this may not work for all of you, but I'm at 6'1 and 215lbs so a higher pressure makes for a better ride (for me).
I'll be sticking to 36/36 [moto]
QuoteTire life isn't optimal, but traction is.
+1. I would rather have the confidence that comes from the extra grip and the extra cost of changing out my tire a bit earlier. In his book "Smooth Riding" Reg Pridemore recommends 32psi for front and back for all tires on the street. I don't weigh much so I run 34/33 and it works out fine.
QuotePilot Power 2ct- 32/32 summer and 34/34 winter.
Why would you run a lower PSI in the summer?
The theory being that the tires will get hotter in the summer and raise the internal pressure. In the winter it's pretty hard to get any rear heat in the tires (if you have a winter)
Next time you go for a ride on a warm day - bring a tire guage with you. Take your pessure when the tires are cold, and then right after you finish up some twistys. You'll find the pressures gone up a few psi.
In the summer the pavement is hotter and the tires get hotter resulting in better grip. If anything you would need less PSI in the winter to get better grip.

Just what I needed.
My manual quotes tire pressure in bar and kg/cm2
The tire wall has it in psi
I went to the garage yesterday and the guy's pressure gauge is in KPa! :o

I'd say about 160 big macs [bacon]
So long as the tire pressure is not higher than the maximum listed on the sidewall and no so low that the tire folds in on itself, you're fine. Nuff said. OEM recommendations are for the following
1) OEM Tires
2) To cover the company from getting sued for safety violations. Thats it
I have found the recommended pressures to be perfect too. 32/30
The Pilot powers will run fairly well with far less pressure though. I rode home some 20 mi. with about 5 psi on two days last week due to punctures.
If you're going to defer to anyone, it makes sense to defer to the manufacturer.
