Hi - I'm replacing my existing bias ply tires with new radials after many years of good service. I purchased my originals from Coker Tires many years ago and they performed well. I'm also looking at the Diamondback tires and they recommended the 820R15 as a good replacement.

My 1949 Cadillac Shop Manual specifications indicate the 8:20x15, so that looks like a good match if comparable.

Does anyone recall if radials will result in a deduction of points when entering your vehicle into the Club's national judging competition? If so, I guess you would need to swap out the tires. Thoughts?

G'day Ken,

Don't forget that following the change to radials, you will need to have a wheel alignment to get the best from the Radials.

The Factory Specifications are not fully compatible with Radials.

An older Wheel Alignment facility, or one with reasonably-aged operators should know what is required, as one can't simply go by the computer directions.

Jay is correct for all cars entered in Primary Division Classes. In Touring Division Classes, there is no longer a deduction for radials on cars originally equipped with bias-ply tires; the radials must be the equivalent size as the original (or optional) bias-ply tires. The Touring Division Class also allows conversion from 6-volt to 12 -volt and conversion from drum brakes to disc brakes. These changes were all first in effect in 2019.
