finally tried out my Harbor Freight Tire changer. Not real impressed. Did the front first, had a few difficulties and learned a few things: -the top arm of the changer is useless, so I removed it -use straight dish soap as a lube rather than a mix of water and soap -bolt the stand directly to floor to get more leverage rear tire -Studded tire was extremely tough to remove due to the inner street tire liner stiffening the tire. -put the new tire under the hood of a running truck for twenty minutes to warm/soften/make more pliable. -use a c-clamp to keep the unworked side from sliding back off/on. No pinched tubes on either one. Not real impressed with the changer. The stand worked well for holding the tire at a workable height in place. The holders were fairly difficult to get between the rim and tire for tire removal and were also difficult to remove after remounting a tire. The long tire iron tool that came with it was the best part of the package. I think my money would have been better spent on one of the other stands that have been discussed on this site.
