As I have posted before, Some years ago I was at a Vintage Sports Car event
at Sears Point and was looking at the Dunlop 18 inch tires. The Dunlop rep
that I spoke to assured me that the tires are made with the same material
and methods as current race tires. And that they are safer then any 20 or 30
year old tire. After that I bought mine and found that some others had been
using them for a while before me. To much pickyness and book reading may
change things in the future.
