Bias ply tires do not separate as often as radial ply tires (has to do with the angle of the plies to the carcass). Probably the most famous example was the Firestone 500 in the late '70s

https://en.wikipedia.org/wiki/Firest...Rubber_Company While the cause was never proved, it is believed that the failure of bonding cements, used by Firestone to hold the tread to the tire carcass, may have allowed water to penetrate the tire which in turn may have caused the internal steel wire to corrode.
Differing from the case(s) of the FORD EXPLODER where the automobile manufacturer recommended lower than optimal PSI to accommodate a "softer ride."

Bridgestone is not a sister company to Firestone, Bridgestone ACQUIRED Firestone in 1988 making Bridgestone the Parent.

Don't now). I replaced the tires on the Judge even though they showed little wear, they were 20 years old. Big (255x70x15) muscle car tires are getting hard to find, may need to go to 17s for the next set.
But back at the nylon cap. Nylon bonds well to both steel and rubber plus it adds and additional ply of strength to the tire. By adding a nylon overlay/cap/ply (all mean the same thing) the tire is made both stronger and more resistant to separation.
Could go deep into ply angles and such. Won't. Only advice: for a single axle trailer like the TM I would only consider a LRD or E and only with a nylon cap.
