Essential UTV Tire Bonnet Tie Down Kit SpeedStrap's innovative UTV tire bonnets keep your vehicle secure on the trailer. Each bonnet wraps around and over the vehicles tire to keep the wheel grounded to the trailer. Unlike other tire bonnets that can only fit a certain size tire, SpeedStrap’s tire bonnets have an innovative design that sucks in against the tire when pulled tight. The top strap has 3 size slots, so it can adjust to fit approx 26 in. - 36 in. size tires. On most trailers, it’s rare to have anchor points that are set perfectly on either side of the tires (unless you have E-Track), so we made the front strap of our tire bonnet adjustable and with extra length so that you can reach more anchor points on your trailer. Rated at 1,300 lb. Safe Working Load (SWL) and a 4,000 lb.
