4 performance Goodyear Fierce Instinct Zr tires for sale on Icon rims. Tires were purchased in July 2013 and were taken off first snow fall. Treads and rubber are like brand new. These tires are phenomenal in rain and stick to any kind of pavement. Tires are rated for 150mph +. I have nothing but praise about these tires! I sold the car, and these tires dont fit on my new one.
