SAFER TIRE JACKING - TIRE CHANGE RAMP in Garages, Trailers, and Towing Posted September 6, 2009 PLASTIC RAMP TO RAISE ONE WHEEL AT A TIMEOver the years, I have had more occasions than I like to recall, to have to jack up a trailer. Either it was a tire change on the side of the road, coming home from a faraway tour, or brake and bearing service, or the oddball repair you run into after years of trailering.Unsure if it would work on my new torsion axle trailer, I bought a really neat, light-weight reinforced plastic ramp. It is made to drive, or back-up one axle of the trailer, so that the other axle's wheel is suspended.IT WORKS !!! It cost less than $ 40. Now I don't have to crawl under the trailer when it is on a floor jack --- always use a jack stand for safety ! Be sure to break-loose the lugs of the wheel you wish to remove before using the ramp.You may wish to place a mat under the ramp to prevent it walking on paved surfaces.There were two types - one has an additional hard rubber surface riveted to the top curve to give an extra inch or so of height. I bought this one, and it's extra height was not really necessary, but works great.I found an additional use - It came in handy for adjusting the brakes and packing the wheel bearings on the trailer --- HOW OFTEN DO YOU REMEMBER TO PACK/GREASE THE WHEEL BEARINGS AND ADJUST BRAKES?
