The GMC CCKW

Can somebody give me some guidlines on evaluating tire quality?
We can't do the penny test on these tires.
Can NDT's be retreaded?
How many and what size cracks make a tire unsafe?
Is holding air any indication of tire quality?

Neil

Ability to hold air....Good ...but you really are only testing the "tube " and not the tire
Even only ONE age/stress crack at max air pressure....BAD...dangerous...and TEX DOT won't approve
The gov't reccapped tires.....but ...why would you want to?
The tire companies ( retreaders ) will reject older casings any way.They are unsafe as steer tires also.
BE safe...Be smart...Buy NEW
Wallace Wade is near you anyway...or ...try Joel Gopan ...I think I saw some "Norwegian " tires during my last visit.

Hope this helps
