Thanks for the information! I have learned a few things from a couple of different alignment shops, as well. I now know how to tell how old tires are. There are 4 digits at the end of the dot stamping on them. The first 2 are for the month & the last two are the year. I am trying to locate a shop that has the wheel balancer that has the 9700 number on it? From some posts in the forum they are supposed to be the best ones. If it warms up some this weekend I will try to get it jacked up and do some visual inspection.
