Hey guys I ride a lot of rocky trails & some coal hills once in a while (aswell as a variety of dirt & mud along the way). I have a set of STI MXC's on the front is holding up well but the rear is pretty shot already after only 3-4 rides. Another few rides and its ready for a new one. Was wondering if theres something that I might get a few more rides out of? Want to try some different tires to see what I like best. What would you guys recommend for my type of trails? 110/90-19 if it matters.
