Well, it's time for the final update on my original set of Roadsmart 2's that I installed at 8K when the OE Bridgestones were worn out. I now have 32K on Traveller and am replacing the front tire tomorrow. 24K life for the front tire ain't too shabby and it will be replaced with another Dunlop Roadsmart 2. The rear tire had a puncture when it had 8K on it and I repaired it with a mushroom plug. It went another 10K with the mushroom plug and began to leak. I had a long trip coming up and decided to replace it rather than replug it, but there were still many miles left in it when I replaced it with another Roadsmart 2. As far as performance, I am a year-round rider and have not had a single complaint about handling, traction, etc. I will admit that I am a very cautious, conservative (read, chicken) rider. A lot of the miles are interstate miles and I do have a TPM system which allows me to maintain the TP's meticulously. I know that many riders on this forum are Michelin fans, but IMHO if you are looking for a solid alternative, try the Roadsmart 2's.
