I went to Sam's today in hopes of getting my tire repaired. No such luck. And not only can they not repair the tire, I got the bad news that I need four, not just one. This car (formerly a rental) that I have had since April 23rd, needs 3 new tires. I was advised that it is not a good idea to put only 3 on, since the next time they need to be rotated and balanced, the older one will have much less tread than the others. It makes sense, but I am wondering what my bad karma is (or should I say carma?).
