The RE050As are the o.e. tire on my '08 MX-5 Miata 6-sp Touring PRHT. These are the best o.e. supplied tires I've encountered on a new vehicle and I'm very pleased with them; both dry and wet performance. Ride quality/noise is acceptable for a max performance summer tire on a roadster. I'm not sure what I might replace them with when the time comes; marginal wear to date with 7.7k miles including one track day and autocross. On my previous '99 Miata, had o.e. Michelin's, Bridgestone RE-71's, another Bridgestone, Toyo T1-S, and 2 Yokohama tires, the last being the S Drive. I am as pleased with the RE-050A as all previous mentioned tires; they provide better wet performance than most and exceptional dry performance with good steering response. Worthy of considering replacing with with same tire.
