Its extremely affordable to get decent all season tires, from a reputable automaker, with an average of a 60,000 warranty and decent traction and performance.
You dont at all, have to trade traction, and or performance for longevity.
Dont buy the cheapies, and dont spend 500bux per tire either. Its very easy to cross shop the major tire chains, Sears and or NTW, to find a decent tire.
Cause when ya gonna need it is when you're in the rain slidin around... or in the snow and your front end is all over the place.
