Very pleased. I did 3 centuries in October with nary a problem. Not cheap, but you get what you pay for.
The Grand Prix 5000 AS TR is a great tire. Puncture-resistant and wearing well. Also, they have a good grip on the decents. Will purchase again. AAA +++
I think these tires are an upgrade to the Grand Prix 4000s that I hav e been running. Great handling, puncture resistance and wear!
