I bought these to tie down my RZR 1000 on a trailer. Wheel tie downs are the only way to go with a long travel vehicle. Tying down the frame just results in loose straps. You can also damage the seals on your shocks by smashing them down and driving. These rubber cleats slide onto the the 2" ratchet straps you place the ratchet strap around the tires and tighten it up. The RZR doesn't even move anymore, these are great and pretty cheap insurance. You could use the ratchet straps on the tires without cleats but it doesn't hold as well and really wears the strap webbing fast. These cleats are also hard to find.
