To the OP... It wouldn't hurt to check with FMCA for prices. Hopefully you will be able to find a reputable service center.
I ordered my new Michelins 5 weeks ago at the cost of about $680 a tire plus tax and mounting.
I had everything planned and organized to have my FMCA tires put on today. I arrived at the service center just before 8 AM for my 8:30 appt. I asked the manager to check the date codes and two of the 8 tires were from December 2012 and other other 6 were from Feb. 2013. I specifically asked for all "NEW" tires, I was madder than a wet cat. I refused all the tires.
Maybe my 7 yrs. old Michelins will get me through another year. I'm sick of service people who will tell you one thing and do another. I'm not a happy camper.
I'm in California and will start back to Tennessee in two weeks, I just may check there for new tires.
