Just got my '08 this week and while cleaning it and stuff I decided to take a look at the tires and discovered they are from 2008. On my sport bike I've always been fanatical about my tire condition, wear and age, going by the general rule that if it's not worn out in 5 yrs it should be replaced anyway. Does this hold true fro Dual Sport tires as well? I'm not going nearly as fast...
