Dallas and J.D.,
I have often heard people make that comment but am not smart enough to figure out why it happen's.
Is it the loss of torque, or perhap's the fact that you no longer are pushing as hard into the air, or a change in the attitude of the car?
My friend Harvey Stackhouse is a engineer with Michelin Tire and believes most of it has to do with the bias ply tires most of us run.
By the way, I sent Harvey over to talk with Tom Burkland and when he came back he said of Tom, "That is one very smart guy who know's more about tires than most Tire manufacturer's".
Harvey helped develop the Space Shuttle's tires, and is now the head of Michelin's aircraft tire division.
He is very interested in our sport but say's it is very unlikely that any tire manufacturer in today's world will be willing to build a brand new "radial design" tire for us because of cost and liabiblity issues, aka Lawyer's..................... Bob
