Over the weekend we had to make use of some emergency finds.
As we were going out on Saturday night we ran over a nail and got a flat tire, just as we were going into a left turn lane with a red light. It was a two lane turn so we weren't really blocking traffic.
I turned on the hazard flashers and set out the triangle (lesson learned: put it far enough over so people will avoid you and not just the car.)
A friendly police officer pulled in behind us just as I was getting the jack set and offered to help, which was fine, as that let me unpack the spare and everything else.
A big plastic bag is great for putting the dirty old tire on to keep things cleaner in back.
I had noticed that one of the tires was getting a bit low in tread back on the equinox, so I have been looking into new tires. I figured I had a couple of more months but this forced the issue. Actually two of the tires were bad and needed replacing.
Tires are pretty much a commodity at the low end, and with more then 100,000 miles on the car I am not going to put really great tires on it. Depending on the sales you may be able to get a good deal but mostly the real variation is in service and other fees.
The real thing comes down to trust. I eliminated one store outright because they were hard selling me when I came to look, and I did not like them.
