I need to replace my front tires (goodyear rs-a). The rears (michelin symmetry) have only 10k on them. Although the Symmetry tires are okay, I'd like to get some killer all-season shoes for the front b/c that's where the power's at! Something like Michelin Pilot Sport A/S. Then eventually they'd move to the rear and I'd get a second pair of Mich A/S. Is there anything wrong with this approach?
