general problems of the 1997 Mercury Mystique

I am an owner of 97 Mercury Mystique GS, VIN 1melm65l7vk621379. When I drove my car for service, the mechanics told me two of firehawk gta p205/60r15 rear tires have a lot of crackles and I should not drive my car on highway before I have them changed. I had the same problem with the two front tires about one year ago, when I changed them at my own expense. This recalled me recent firestone tire recalls. Unfortunately, this type of tire is not included in the recalled models. Now I think this kind of defective is not individual case. My car has only 26452 miles as of today. I would like to suggest you investigate this type firehawk tires too, firehawk gta p205/60r15, for the safety of millions of Ford vehicle drivers. ( dot number: tire size: p205/60r15 ).
