My girlfriend had a flat on her trailer with horses on board. She had a TrailerAid but we had a really hard time getting the lug nuts started. Put the lug wrench on (big "X" style) and she balanced it while I stood up on it. Jumped up and down (holding onto the trailer of course) to loosen the lug nuts. Worked a treat, as the Brits say, and we got the lug nuts off, drove the trailer up onto the TrailerAid and changed the tire. Not one person passing by on the road even looked at us struggling with the tire, never mind stop to offer help - - - until we were putting the lug nuts back on, when a couple stopped and the woman called out to us, "Do you gals need help?" We told her we were just about done and saw her husband heave a sigh of relief. She shouted out, "Go West Virginia women!"

The Trailer Aid is the answer but also, be sure you have a lug wrench that fits your lugs. Be sure your lugs haven't been done up too tight. Be sure you have some reflecto triangles to set up in the road to steer on coming traffic away from you. Be sure you have a good stand-alone flashlight. Be sure your spare has air in it. Be sure your USRider is up to date and best of all, get your flat on ANY highway in New York State. They have roaming highway good samaritans who show up almost before you can get out of your truck. They change your flat and disappear into the night faster than lightning. Heavenly. O, and no, do NOT take your horses down out of that trailer if you can POSSIBLY avoid it...
