Looked in the both the owners manual, on the tires, and on the forums but can't get really solid recommendation for tire pressure on my '07 America.

My riding is about 75% on city/surburban roads - sometimes bumpy, and about 25% interstate. Tires are the stock Metzlers. I've got two medium size saddle bags but don't put too much stuff in them. My weight is on the heavy side, at 220.

Can anyone recommend the right tire pressure for my setup?

Thanks!
