I am going to run 11.00R16 Michelin tires on my 1982 chev 4x4 dually crewcab and can get the tires worn-out(worded funny). I would like to get them retreaded and run them. I have two new tires to run on the front and the retreads will only be on the rear. What should I be aware of before doing this and is this even a good idea? Why or why not? Anybody ran something like this before?
