Re: [Chrysler300] 300F

I would not make a decision solely based on that story - while the tire 
technology of that day was not what it is today, the tires were no doubt 
fresh and possibly even the special high speed tires designed for the 
competition. I know from personal experience we could generally get a 
set of freebees for car show and display purposes from Goodyear as they 
wanted to show off their latest and best at any publicity opportunity.

But I digress - my point is this - the low production nature of the bias 
wide whitewalls makes them more likely to be older stock and older 
production methods using hand labor rather than automated technology 
used for higher production bias ply in their day or the current high 
precision methods used in radials. This combined with age can lead them 
to be more problematic at speed. Even radials with significant age 
(defined by various groups as "anywhere over 5" to "10 or more" years 
old) have issues. And tires parked for long periods of time typical of 
antique cars left can develop memory type flat spots.

If you are going to drive the car at speed - defined by me as 60 mph +/- 
or sustained trips, make sure the tires are up to it - and the tread 
left is probably the least significant factor for most of us. And I 
choose 60 +/- MPH because that is speed where harmonics come into play 
with respect to any imperfections of balance or roundness and tire 
problems tend to be aggravated. Its also a speed where a blown tire can 
do a lot of damage to you, the car, and potentially others around you. 
Trailering or lower speed short distances to car shows may be another 
matter where old tires are less of an issue.
