What's the type of terrain you're "mostly" riding in...i.e.,grass/loamy,sand/mud,rocks/hardpack??
If you throw on a fresh sand/mud tire,and start riding in all kinds of hardpack and rocks,you're gonna kill the tire almost instantly.
It almost sounds like you want to find a good Intermediate tire since you're kinda into alot of different areas.
Here...take a look at some of these,and read the reviews(if there are any to ones that interest you).On the left side you can pick from several different types.
