When a manufacturer orders tires, he might order 10K. He then might use only 4K. He does not throw the unused inventory away, he stores it. He might not even use up the rest next year, or the year after that.
Now, tell me how you leave a stoplight...
I agree!
Stoplights are the biggest factor in tire wear. If you do fast starts off a light you will wear you tires much faster then if you take off slowly. There are also different compounds for tires too. You can look for a harder tire, this will wear longer then a tire that is used for hard cornering and heavy performance. Many manufactures make duel compound tires, hard in the center for longer wear and soft on the side for hard cornering. Check out the brand that you like and see if they have these types. I use Donlop and am quite happy with them.
I found that old tires tend to get greasy. They will slide easier then fresh. I don't agree on what he says about the age of new tires. Whenever I buy new tires I make sure that they are less then 1 year old. You can tell the age of tires check out the following. Here is info on tire date code:
Taken from MotoTireGuy
Every US Department Of Transportation (DOT) approved automotive and motorcycle tire has the tire date of manufacture stamped sidewall. The format of this date appears in a WWYY format, as in week/year. For example the manufacture date code of 4407 translates to the 44th week of 2007. Tires produced prior to the year 2000 use a three digit code. For example the manufacture date code of 378 translates to the 37th week of 1998. New tires should be less than 3 years old. I recommend discarding used motorcycle tires after 8 years of age.
