are they retreads or recaps? the differences are , retread has the tread cut into the the tire, recaps are another piece of rubber with tread on it, bonded onto the tire . either way i'm with the others. the tires are cheaper, but less reliable . i have them on my work truck (recaps, no choice of mine) but you are subjected to slow leaks and the risk of throwing the cap off if not bonded well. and also you get what i call 30mph hump(the whole vehicle bounces up & down). where i am they are not legal for the front, tells me that they are not so safe. you half to remember that the core already has high miles on them, sometimes that's all they have been designed for. as always it's you're choice but as for me i'm on the negative side, hope this helps.
