I think the problem is as follows:

This is a Panaracer Pasela 700 x 35 mm tire that is listed on the tire itself as having a max pressure of 90 PSI.

The specs on the Nashbar website list it as having a max pressure of 75 PSI.

I've been running it at 85 PSI that is probably too high, and it's stretched out.

I carefully inspected it and don't see any broken nylon strands on the inside but do see some cracking in the rubber on the outside.

The front tire is the OEM 1990's Cheng Shin that is also starting to crack.

Time for new pair of tires I guess. I was thinking Vittoria Randonneur Road Tire but they're a little pricey.

Any suggestions or comments?

Thanks for the input!
10psi over the nominal rating shouldn't create the problem you describe. I routinely run my 90psi tires at 110psi without issues or undue wear. I think you got a defective tire there.

The Vittoria Randonneur 700 x 32 or 700 x 35 would be a good, tough tire: http://www.biketiresdirect.com/produ...andonneur-tire . It's going to be somewhat heavier than the Pasela, though.
