I use to run on the Diamante Pro Lights but they too wore out too fast. I went to the Diamante Pro because of its claims of durability (within its class).
Like the first reviewer said, I didn't expect these lightweight tires to be tough as nails but I also didn't expect to see the tire form a bulge after 2 rides (about 60 miles total). I liked the feel of these tires and it they were more durable, I'd be a loyal fan.
I think I'll need to look elsewhere.
