Advantage radials to Bias Plys

Rose Racing · 07-07-2020, 06:12 PM

How large is the advantage of a radial to a Bias Ply? I know of all the advantages of a Radial tire but in reality how big is the gap especially on a slow U/SA? I know its rare to see an Auto car with slicks nowadays..... How large is the gap in ET/Speed? Can you still win a National or Division on Bias Plys are they consistent enough to compete at a high level?

Worth at least a tenth to twelve hundreds on my N/SA Mustang. I guess a lot would depend on how high air pressure you can get away with in your bias tires.

I found about a tenth with a lot of that in the 60'. Also helped reaction times a bit, less wrap up.

I went 2.43 under with the bias ply slicks and was afraid to run the radial.

Had both on U/SA olds wagon. No difference other then the air pressure
