My tire has the following information on it:

665kpa, 6.7 bar, 95 PSI

So I have two questions:

1.) I'm a heavier dude...260 lbs. Is it better to inflate the tire to 95 PSI? I don't know why, but for some reason I've been riding on 80 PSI. The rides been good, but 1) I wonder if it could be better and 2) if I'm causing or may cause damage to the wheel by under-inflating.

2.) Just read online that it's better to use less pressure on the front wheel (so 90 PSI?) because it'll give you "better traction?" Is there any truth to this? Should I go with 95 in the back and 90 in the front? Or stick to what I've been using? About 80 front, 80 back?

Any comments/suggestions would be greatly appreciated.

Thanks!
