bought this to tie down car on auto hauler; car has 17" wheels; straps and ratchets are fine. Issue is the strap on the non-ratchet end. Unless you have a 2nd ratchet that end does NOT have a very tight connection; the tire friction prevents the front ratchet from being able to pull the strap tight on the non-ratchet end of the strap so that end is not providing the full support it should. Just a thought as I haven't tried it; but if you put a tarp or something that the full tire loop could slide on while being tightened
that might solve the problem.
