Truck rarely use retreads anymore as it does not pay... the price of tyres has come down a lot for trucks and the time lost on the freeway stuffing about with treads flying off far outways the cost of putting proper tyres on.

This is from a conversation I was having the other week with an owner of a trucking company with 10 trucks in his fleet.... so if I am wrong its cause I am a sucker.. bwa !!!!!!!
