Correct Tire Pressure...

[021Lucky]

I've had it drilled into me since I was a brand new rider that correct tire pressure is *muy-importante*...

Last year I bought an '89 CB-1... the owner before me had replaced the OEM tires with a harder compound touring tire. I have no idea what the original OEM tire was. Does anyone here know?

In the owner's manual, Honda spec'd the correct PSI as 33F/36R. This applies ONLY to the OEM tire.

So, this past weekend I put new tires on - Michelin Pilot Powers. I just called Michelin to find out what the correct PSI should be. The customer service rep helping me seemed all too eager to get me off the phone. He said I should use whatever Honda spec'd in the owner's manual.

How can that be correct? The new tires are a completely different compound, profile and not to mention size - my OEM rear tire was a 140 - Pilot Powers start at 150, and so, since I wanted more of a performance tire - I moved up to the 150.

The more I think about this, the more complex it all seems... correct tire pressure has to do with the tire, the rider, the bike, the type of riding...

and since I spent a pretty penny on the premium rubber... I'd like to protect my investment and have these tires last as long as possible.

Thoughts?

It does not matter what the pressures were for the stock tires.  You only need to know what the pressures are for the tires you bought.  Customer service is very important to me.  I would have asked to speak to a manager, the second that kid finished saying, talk to Honda!  UNACCEPTABLE!  After getting the correct pressures from the manager, I would have informed him what the kid said, then informed him that this would be my first and last set of Michelins that I would purchase.  Thats just me...

K.I.S.S  Keep It Simple Sir!    Dumb people, like that kid, is what makes things complex.  Every set of tires have their own specific tire pressures.  You bought Pilots Powers for your CB-1, and the set you bought has specific tire pressures.  Period.  Once you set those pressures, you are good to go.  The ONLY time you would need to adjust those pressures, is if you experience extreme weather/temp changes.

Welcome and enjoy your new "shoes"!

The pressures listed on the chain guard on my 1990 are:

90kg (~200 lbs) and under - 33 front, 33 rear
91kg (~201 lbs) and over - 33 front, 36 rear

Hope this helps,

I was raised on 34 all around.

[X.A.]

32 PSI (2.25 kg..)  BT45Front
36 PSI (2.50 kg..)  BT45Rear

On TAG on frame.
OK rear but maybe not so good front, looking the way it wears.
