First, thanks for all the input . Just to clarify things a little, he did put 4 new tires on. These were the 4 they had available in our small town tire shop that would fit. The info I was seeking has been answered to my satisfaction, which means I will start over with a new matched set and keep a good spare . I didn't make it clear but he actually did this a couple years ago. I just got around to paying attention to the brands a little while ago. Anyway, thanks again. Sorry about the can of worms .
