Along with my regular crawling under Mustangs to install various parts and do a variety of maintenance, I have two vehicles that have winter tires on rims that I have been jacking up, one wheel at a time, twice a year to do the change over, that will be much easier, and quicker to do. Given the vehicles I have, I don’t think I will need the extensions, but I think I will buy the hangers to store them on the back wall of the garage. Most of the reviews are good, once you tighten the fittings enough to stop any leaks. One of the biggest complaints in the reviews is how heavy they are, but I think there are wheels on one end.
