Kurt... Yes, hope to see your car some time. May look you up next time I am in town.
I think your Avons were the vintage treaded Bias tires. Agreed that they are seemingly fine when new, but go south quite quickly. The Avons on my car are the CR6ZZ's. Wonderful tires. They are on my GT now for the third season. Still seem as good as new. I would like to replace the Hoosier DT's on my Cobra at some point. Thinking Avons for that as well. But wondering how the TD's would work.
