Q: What about the importance of tires and tire pressure?

Answer:

Check your tire pressure once a week, and stay within the guidelines on the sidewall of the tires.  Change tires when they get down to 3/32 of an inch of tread.  If you are an average rider, no burnouts and such.  You should get about 6,000 miles on a rear tire, and about 8,000 miles on a front tire.    Another rule of thumb is two rears to one front.  Most people run tires too long.
