i just got my car back from having 3.73's installed, and i cant get any traction! i have nankang 245/40/18 tires all around now, which suck, in any condition. i really want a good hooking tire, that still makes me feel a little safe in the rain. Im only looking to get two for the back right now, most likely in 275s. what will get me the traction i crave??
