Same here. Plus our winters aren't so severe normally to warrant leaving them on all season and chewing up our bare driveway most of the time, so I can just swap them on/off as the forecast/conditions call for it. They'll also last for pretty much the life of the vehicle at this rate. The savings from not paying a shop to do it will pay for a nice floor jack in about 2 changeovers. The first time was a bit of a grunt, but since I've done it a few times now and added an impact driver to my tool arsenal, it's down to only a 2-beer job (or just 1 if I'm in a hurry, but I prefer to enjoy the 2nd beer while I'm at it because I don't want to make it look too easy and thus not win as many pts w/ the wife ~ this is one of those scenarios where the 2nd beer is actually to my advantage...).
