I got Tire Shades from Zip Dee. I have a '02 Safari, tandem axle. They custom make the covers to fit your unit. They attach to the side of your unit with snaps, which they send you. Know the height of the shades you want before you call. They will make them to match your awning with the same material. Mine are 29''x 74" to fit tandem axle. The cost was $143 without shipping.
I think they are well worth the price. Zip Dee 800-338-2378.
