tire pressure

[norcal1]

A few months ago I got a new pair of Michelin PR2's.

The shop set the air pressure in both tires at 35 psi. I can't find anywhere what is Michelins recommended pressure.

The tires ride great,much better than the stock ones.

Any suggestions? What do you run your Pilots on?

35 is a little low. Most here will probably recommend 38-40 in front, and 40-42 in rear. I weigh 190lbs and ride solo. I set mine at 39 front and 42 rear.

I'm 200# and run 40 front, 42 rear

With all due respect, this thread wound up right where it deserved to be. NEPRT. And quickly too. A quick search would have been easier.

I really thought the tire itself would have the max pressure info on the sidewall. Are you certain it is not there?

I run 41-42 psi both front and rear. Yes it will ride smoother at 35 psi but it will wear out faster as well.

I run 38/40 since I ride without bags installed and am only 180 pounds. I do not like the rough ride at 40/42, but that is just me.

180# with full gear, 40/43 in BT-023GT tires. Long tire life, even wear and still good grip. I drop maybe 1/2 lb pressure if it is hot and most of the riding is going to be up in the mountains or in canyons.

+1, 40 F & 42 R

The other question...why would a M/C shop send you out with under inflated tires when the recommended pressures are clearly displayed on the swing arm.

I'd find a new shop...

This.

42/42! I weigh 225 often ride long trips loaded, camping gear, etc... Check my tire pressure cold, before "Every" ride and adjust accordingly! PR 3's

 

[Top_Speed1]

PR2's; 42F | 44R

Exceptional long life (well at least what I think is @~10K), I'm 235lbs, ride mostly 1up w a mix of spirited and smell da flowers riding. Avoid slab when I can.

the shops around south Louisiana are used to servicing cruisers, and they tend to run lower pressures. I had to train my tire changing guy to put higher pressures in my tires when mounts my tires. I have a buddy that is a HD certified mechanic,and still insists that 32-35 lbs is the correct pressure, but since he only rides and works on Harleys, he basically don't know jack about motorcycles. I will continue my quest to educate him.

Go by what the book says. Many shops will just guestimate and send the bike out the door

Doesn't matter who blows up my tires. I'd recheck and adjust to my preferences as necessary anyway, and I wouldn't expect any shop to know what that is.

Mostly 42F/44R.

Just about every motorcycle tire has a max allowable pressure printed on the tire of 42 PSI. This is not a recommended pressure for any bike; it is max safe pressure specified for the tire. The max pressure on the tire and the recommended pressures provided with or on the bike assume the pressure is measured at 68 degrees F. You can assume about a 1 to 1.5 PSI change for every 10 degree change in temperature. Putting 44 PSI in a tire is probably not a good idea, especially if it is done at a temperature significantly below 68 F.

I mount my own tirers...39F/41R.

Ol' RaY is a frost-back from Kanada, he dreams of days when it gets up to 68º.

OK, you are kneeled down putting 42 psi in your tires. Now you and your pillion get all geared up, stow your stuff in the bags and climb aboard. With all the extra weight, what happens to the tire pressure that was set on an unloaded bike? I rode a bike with a TPMS and I know what happened on this bike as well as what happens when the tires get hot too.

 

[Pterodactyl]

'Below' was correct. Of course the pressure in the tire will rise as they become warmer. The 42 PSI at 68 degrees (considered a cold tire) is a standard that accounts for tires being used at the max specified load at a max assumed tire temperature. So a tire that was inflated to 42 PSI in your garage may be operating at a significantly higher PSI as you cruise at 70 MPH with a fully loaded bike. The 42 PSI at 68 F standard is a way to ensure the tire does not fail at the max performance levels (weight , speed , temp) specified for the tire.
