I am looking to replace two rear tires of '04 Honda S2000. The current front and rear are Falken FK 452, sizes: 225/45-17 Front and 255/40-17 Rear. The tread life of FK452 is rated at 300 but the rear are almost at wear bar only after 12-13k miles. I'm looking for longer tread life tires, the one that can lasted about 20-25k miles, I'm tired of replacing the two rear tires every two years or 15k miles. The size 255/40-17 with speed rate W or Y is expensive, more than $300 for two for most brands. Kelly Fierce UHP can be purchased online for less than $100/ea and mounting+balance is less than $20/ea so that the total is less than $250 for two. The tread life is rated at 420 so that it may lasted more than 20k miles. Your experiences with Kelly Fierce UHP is appreciated.
