Let's all just hug.......
In all seriousness, IIRC the general rule (I have no idea who made the rules) is that after anywhere from 2 - 4 years, tires should be replaced. How often depends on several factors, including how much you ride (wear) and where it is parked (UV damage from the sun). Look for the manufacture date on the side of the tires, it should be in month / day format. Anything older than 3 years (my personal opinion) should be replaced, because new rubber is cheap compared to the alternative.
