Ok, so after 4,000 miles my rear tire needs to be replaced (yes I've ridden this tire hard). Used this one for practicing sitdown wheelies, stand ups etc.. I just replaced my front tire with a Metz as well, about 200miles ago. I would like to try the Pilot Power, but not sure if the compounds are too different or not. I've never been one to always run the same type tire, just always made sure I used same or similar compounds...nothing like having a soft rear and hard front for some squirrelly mountain twisties (or simple to/from work rides). Whats the masses say about PP in rear and Metz up front, or should I stick with another Metz in the rear until the fronts ready to be replaced?
