I started this thread (almost five years ago) three months before my Overlander hit the road for it's first trip after a 23 year hiatus from active camping. While there were many obstacles to looking good on the road, the spare tire cover was important to me, and I was quite pleased with my original solution since I paid what I thought was too much money for it.
My first solution was an aluminum-color, diamond-plate pattern, spare tire cover made especially for Jeeps. It looked good, and I thought it would last forever.
Two years or so later, it proved to be UV-non-resistant. After yet ANOTHER exhaustive search for the best cover, and failing in the quest, I asked Santa for another cover like I had, and my mother-in-law obliged. Two years later that cover too also proved un-sun-worthy.
Six months ago, I renewed my search and found nothing but the same-ole same-ole, and decided to wait until next season to do something about it. Then, the opportunity to actually
attend the upcoming
Texas Vintage Rally presented itself. All those polished Airstreams

- the least I could do was to have a decent spare tire cover.
I finally entered the right keywords into Google - A non-related search revealed that the best exterior coverings are made with Haartz-brand fabric. Checking their site, I found that the Haartz company specializes in fabic made for convertible tops & marine coverings.
Bestop.com uses their fabric in the production of spare tire covers.
Number Two Son was kind enough to get out in our frigid 40 degF weather to pose with the old & new covers. Look out Texas, Kim & I are coming and we're looking good
