Hi all. I was wondering if anyone knew a quick fix to give the drive wheels on my G3 more grip on the carpet short of replacing them for now. I had a second machine I was going to pirate the wheels from but had to leave it behind when we moved last month. That machine had other problems but good wheels, this one runs smoothly but the rear wheels have lost most of that rubbery coating so when it goes in reverse they do more spinning than pulling.
