I own a 1999 CBR600 F4 which has a front Michelin Radial Pilot Power wheel (120/70ZR-17) and a back Michelin Radial Power wheel (180/55ZR-17). In my service repair and maintenance manual: HONDA CBR600F4 1999-2003 (published by Primedia) it says to inflate the front wheel to 36psi and the back wheel to 42psi. However, my Michelin wheels say to inflate the back tire to 42psi (it actually says "At 290 kPo (42psi) COLD) and the front tire to 42psi (it actually says the same thing as the back tire). My question is whether I should go off what the tire says to inflate the front tire or what my manual says.

thanks,

Andrew

 

Go with whats on the tire. The values listed in a manual are likely for stock OEM rubber.

 

Will do, thanks.

 

Thats the MAX cold pressure it should be at. I run 32/32

 

I'm close to the same. I run 32 front 30 rear.

But like Nauree said, thats the max the tire should see. In fact, that rating is for isif yourbike is at its max load, then the tire should be inflated to that pressure. So unless your a 400lbs dude, you dont need the max psiin thetires.

There are a couple of problems you can have by having your tire pressure at its max. Your bike will ride harsh as the tires have less give to them. During acceleration or cornering, your tires will conform to the road less and you will loose traction easier.

If your not a very aggressive rider, you probably dont have to worry about the tire pressure being too high. But, if you are aggressive, you may want to consider tire pressure at lesser psi.

as a rule of thumb, I never go below 30 psi. But thats just me. I'm sure some out there go less than that.
