Here's what i was told: Find out how much weight is on the wheel (weigh it somehow) for your normal riding conditions and add a bit onto that for when you have a few too many burritos for lunch. Read on the sidewall of the tire what it's maximum weight carrying capacity is at full pressure. Calculate what percentage of that maximum capacity the wheel is actually carrying (from when you weighed it) and multiply that percentage times the maximum pressure written on the sidewall. The result is the pressure you should be running. If you increase what you are carrying like loading up for a trip or riding two up for any distance, increase pressure accordingly. At least that's how it was explained to me by a guy that started riding around the time god was born.
what?

Always go with what it says on the TIRE. No matter what vehicle you're dealing with.Check tire pressures COLD.

Avoid using winter air though.

Read the book again. They give two readings. One for solo...one for 2 up. The 42 is for 2 up.

The manual is your best reference. I run a few pounds softer in the rear like your dealer said. The bike rides a little smoother. Dont go so soft it affects handling. To little air pressure will cause a build up of heat and blowout. To much air will cause over pressure and blowout. I run the front tire at what the manual recommends the bike handles best. Never go over the pressure on the sidewall for oem or non oem tires.

So the sidewall will give you the max pressure. The manual is a recommendation from the manufacturer and you can play with a few pounds for your comfort.

Clear as mud right?

Michelin states in their literature to refer to the owners manual. Maybe they are the exception, but they design their tires to spec to factory.

I like to take care of my ride, so I may hike up to the top of a mountain and bottle up some air and store it at home for just such an occasion.
