I bought a used red 2001 GZ 250. The tires are original and tread is fine with only 2450 miles. I am replacing tires due to age (11 years old). I only ride recreationally and want a good safe tires as I am a beginner. Please offer suggestions on tires and why you think they are good and where can I get tires at a reasonable price. Any help or suggestions is appreciated. Thanks. Nita in Nashville
