 With 29,000 miles on the original (junk) equipment tires, I read several tests and found a very good replacement tire for the Mazda3.  Try: Continental Extreme Contact DWS (Dry,Wet,Snow) They transformed the car, with much improved wet and light snow traction, much less road noise, better steering feel and much better tar strip and rough road performance.  Have 5000 miles on them so far. A very good all performance season tire.  Also much cheaper than replacing the factory original (GY) rubbish.
