I know that they are light and are good for mud and loose dirt, but how is the wear life? Do they last longer then the stock tires that come on the early 90's trail boss? because they wear down real quick.

 

Depends greatly on how you treat them, get em hot riding a hard rocky trail and they'll wear quite hard. A general rule of thumb is mud tires dont last a real long time outside of using them in mud. (they are usually a relatively soft compound).

 

The answer is yes they do last longer than the stock tires. They will wear quite fast (like all ATV tires) if they are ridden on pavement. This an excellent choice for a replacement tire.
