Dunlop has discontinued the Sport 5000! My first set lasted 46,000 miles, the second set lasted just over 25,000. Dunlop will not make an adjustment, as they say the tire is rated for only 25,000 miles. In 3 months and just 2500 miles the apparent "soft" tires lost 3/32 tread, making the tires "illegal" to drive. I bought the same tire, with good luck the first time around, and their only response is that I was Lucky!
