Tire Pressure question

Hopefully not opening a can of worms here but I jut got a set of Michelin PR3's and I was wondering, only because it's not listed in the owner's manual as a type of tire for this bike (not invented at time of factory roll out), should I still run the recommended 36 front and 42 rear? The buys at the store sent me out with 36F/40R.

Note: I am riding for longevity of tire and will do spirited rides occasionally, but mostly back road loping.

 

Go with the recommended pressure to get acquainted with your new tires. Once your comfortable maybe play with pressures a bit & see what feels best for you. A couple psi either way can make a noticeable difference in handling.

 

+1 to what Arnzinator said. Use the factory recommended for slab/touring and drop a few PSI when your in the twisty stuff, but remember to check/set air pressure when the tires are "cold".

 

I run 33 f and 36 Back-seems to ride nice like that-. too much air makes it want to fall over and is bad on bumps.:snowman:

 

Well, I did find this:

I run 33 - 38 works the best for me . I use to run the 36 - 42 But I don't think the bike handles as well . much better with the 33 - 38 .
You will have to play with it and find your sweet spot .

 

The tire manufacturers all have websites. If you don't find one, you wouldn't want to run their tires anyway. Lots of tire info on the company sites.

 

Michelin doesn't make any mention of pressures on their PR3 page.

That is exactly what one would expect from a bunch of French fags who eat frogs and snails and other shit like that.

 

Go to Michelin website for motorcycle tires. Click on Advice, then FAQ's. They recommend bike makers spec's. There is also a link for recommened pres for track applications.

 

With pilot road 3s I run 36/42 for maximum tread life.

 

What is the recommended pressure on these if two up?

I think the max tire pressure on the side wall is the recommended for 2 up.


Dunlop prints specific tire pressure for hot and clod for their slicks. GPA 211 - Hot is 33 front 23 rear
Cold is 31/21. Always thought these were odd numbers but trusted them. Works great.

 

From Michelin's website:

WHAT PRESSURES SHOULD I PUT IN MY TIRES FOR NORMAL ROAD USE?

For use on the road, it’s essential to use the tire pressures recommended by the manufacturer of your motorbike.
You’ll find it in the bike’s handbook or on the machine itself.

The inflation pressure stated in these documents is the pressure when the tires are cold.

NB: The maximum pressure indicated on the tire is never to be considered for road use. This is the pressure corresponding to the tire’s load index.

 

I am so glad everyone agrees. We may have reached a new plateau where the hot air is rarefied.

 

I run 36/36 and the bike handles perfectly like that. I don't ride 2 up or have luggage though. The tire shop put 36/42 when I left and I Immediately felt the awkwardness so I deflated them to 36 and has been well since

 

My tires say: "made in spain" on the side...

 

Michelin is a French Co & has facilities around the world.

 

I used to own a 2004 FJR1300, it wore the exact same tires as my VFR. The manufacturer stated tire pressure for the FJR was 32-36 (f-r). Now that bike is a much heavier, more powerful steed. So I have wondered about just how the mfrs. come up with tire pressure specs, do they look at tire mileage, ultimate handling, or what. We can all guess, but I would love to hear from someone at American Honda, or similar credentials. Failing that, I feel OK trying tire pressures anywhere in the zone, and have settled on 33-36.

 

Dunlop has very specific info. Good read.
