Performance Tire Plus has a great sale on many Nitto performance tires for the next week (thru 6/30). I just picked up a new pair of NT-05 rears for my car. They also have free freight (with a small boxing and handling charge). I don't know if they have other brands on sale as well - I didn't check. If you're in the market for tires, check them out.
