I traded cars and went from a 14inch tire to a 17inch tire and I needed new straps for a larger tire. I purchased the $37 dollar Demco style basket straps to use on my Demco dolley and was completely satisfied. They were just like the oem Demco straps and worked great.
If your straps are coming off you’re not strapping them down right.
When I first started using the dolly I strapped the toad down as Demco recommended by pulled the toad all the way forward to the front wheel stop but I found that the straps came loose & I even had one strap come all of the way off. I then realized that the straps won’t slide over the wheels as they are tightened so they remain a little loose behind the wheels and when you started pulling the Toad it slips back leaving the straps loose on both sides of the wheel.
With this in mind, I now pull the toad all of the way forward then back about an inch & strap it down until the tires squish. As the straps tighten the wheels is allowed to roll forward and the strap tension equalizes on both sides of the wheel. Since I started doing this (over 33,000 miles ago) I’ve never found a strap loose enough to cause a problem. I still check them within 50 miles of start and again each time I stop (about every 2 to 3 hours).
I talked to Demco about this procedure and they have no problem with it but have chosen not to change the guidelines in their manual.
1. If your dolly is a little wider than the RV watch those right curbs when parking. I ground the lettering off of the right dolly tire before I realized this.
2. Make sure that you allow plenty of front end room when parking along a curb. If you have to turn too sharply when pulling out the rear of the RV swings in the opposite direction pulling the dolly into the curb causing the dolly wheels to scrap or roll over the curb.
