Does anyone know why the front PR2's tread looks like it's running backwards? It seems counterintuitive and to me it looks like it would direct water to the center. I know what was said in the other threads, 'Michelin tire engineers must know what they're doing and it does work well in the wet'. I was hoping for a little more than that...I checked the directional arrow...twice now...and for some reason they just don't look right - thanks
