I don't need a golf cart but I must question your decision regarding the current tires on your trailer. I have had trailer tire blowouts on interstate highways twice now and it is a horrible experience. One such blowout actually ripped the fender right off my trailer before I realized I had a problem. Chancing such a drive on known questionable tires either with or without a load just so you can save a few $$ when/if you make it home makes no sense to me. I was on I-95 and the drivers side trailer tire blew. Changing the spare on the interstate with cars and truck wizzing past me at 70-80 MPH was the most dangerous thing I think I have ever done. My trailer and the tires were all new and in great shape but I hit some junk on the road and it punctured the tire. You could never get me on a major highway with trailer tires not up to snuff for any dollar amount. Be safe Fred, I am going for new trailer tires today and both have plenty of tread on them but are weather checked and showing signs of age cracking so they are junk IMO and I doubt the tires have more than 500 miles on them yet they sit around on grass and wet pavement baking in the sun or freezing in the snow 340 days every year. Dragging my boat from Lake Ontario back to home I hit a pothole and broke the leaf spring on the trailer which caused the tire to get nearly ripped right off. It cost me $175 for the flatbed tow and another $250 for the repair and new wheel and tire not to mention the 8 additional hours on the road for a 4 hour trip.
