They go very well with my tandems (you provide your own shock cord). Considering that I have upgraded my wheels and tires (Sendel T07) they keep both wheel and tire clean as my trailer is not in constant use and can get very dirty in there. I also have a set of these (single) wheel and tire covers for my RV. I highly recommend protecting your wheels and tires from dirt build-up, as well as from harmful UV rays that damage tire sidewalls.
