Ed,

This has been covered a few times before. What they told you is technically correct, however, they're telling you that for liability reasons. A good plug shouldn't cause you any problems provided that you don't take the car to excessive high speeds since that plug renders the Z rating ineffective. But, it doesn't mean that the tire isn't still useful.

I honestly wouldn't worry too much about it. If you want to get new tires, fine, but feel free to do it at your leisure.

Also, I'm a HUGE fan of Tire Rack (online). I ordered 4 new tires this past Friday - they arrived on Monday - installed on Monday. I saved myself a BOATLOAD of money and got exactly the tires I wanted. Seriously, I can't rave enough about that site.

Good luck.
