I'm with Bugman, you have no idea of the quality of the carcass. Lots of logging trucks in my area used to run Bandags but not on the front axle, they're high quality long wearing caps. Years ago I had used them off and on but finally blew out one on my pickup in mountain country while pulling my horse trailer. The cap didn't separate, but the sidewall blew out and I wasn't even close to the tire's max weight rating. Never again.
In the US they're one in the same, never heard of recutting tread, if the tires worn out and you recut new tread you'd be well into the cords.are they retreads or recaps?
