Hi Chet,
Welcome to the Corvette Action Center!! We're happy to have you here.
People with Corvettes wearing runflats end up having to make decisions as to whether to replace the original runflat tires with more runflats or go with non-runflats. My husband's '02 reached that point last summer, and we chose to buy Michelin Pilot Sports (runflats). We wanted that little bit of security that the runflats bring, and the Michelins are great tires...good handling, much more quiet than the old GYs, and less expensive.
Sounds like others have given you good advice about plugged tires. Now, get out and enjoy that 2000!!!
