Tire Pressure?

Hi All;

Just wondering if tire pressure is best determined by the tire or the bike. I have a new Continental Road Attack 3 on the back of My V7 III Anniversario and it feels a little soft to me.

I have searched a lot online and some people say to go by the marking on the tire, others say to never go by the marking on the tire. Some say to go by the pressure noted by the bike manufacturer and some by the tire manufacturer. I cannot find the information of the Continental website. What do you folks recommend?

Thanks
 
The juggle of this relies on many factors... your weight, the ambient air temp, how much mileage vs. traction do you want or need (is always the question). Lower range tire pressures give you better traction, more wear. The more you raise the pressure, the longer life of the tire, but less traction you'll get. How much load the bike will carry is the other component. Heavier riders or loads will require higher pressures. I've road-raced on as little as 19 psi in very cold temperatures, and as high as 38 psi. My recommendations for solo riders of average weight on the RA3's is 34 front, 36 rear. Those can be equally varied 2~4 psi depending on load and temps. Max pressure stamped on the tire is for max load per Guzzis recommendations. I can't say I've ever run it regardless of the load I carried (2-up with full luggage, never more than 38 psi).

Sure someone will try and make me wrong... but there you go.

Agreed. I ride the manual recommended 36 front and back on my v7III Special solo and 85kg - Michelin Pilot Activ. Gives good feel and good wear. Even ok two up for trips. Try +/- a couple of psi until you find what feels best for you.
 
The pressure on the tire is the MAX tire pressure it is rated for. Unless you are running it at maximum load that pressure is not the correct pressure. In general, the tire pressure the bike is rated for is a great starting point. But differences in tire construction, as well as differences in tire size (larger tires generally need less air pressure to properly carry a given load) can require adjustments to that tire pressure.
