If you're like me, you're tired of the wheel covers popping off your car. Especially when they're wheel covers that you can't replace with a catalog. Even with bias-ply tires, hubcaps have a tendency to work themselves loose and pop off. With radials it's worse. Recently I tried out a solution using a product I found in the grocery store for less than $2.00 a pack. Two packs will give you more than enough to do all your wheels. Ready to have a good laugh? Stick-on Velcro! Yes, I'm serious. Step 1. Stick a strip of Velcro onto the portion of your rim where your hubcap's "teeth" usually contact, centered on the valve stem. I prefer to put the "hook" side here. If your rim has a little surface rust, it could help to clean it up just a bit with a wire brush or sandpaper. Step 2. Stick the other half of the velcro on your hubcap's teeth, centered on the hubcap's valve stem hole. I prefer to use the fuzzy side here. Where the hubcap teeth bend back toward the outside, tuck the Velcro underneath. You may want to trim this strip so that it doesn't poke out between the hubcap and the rim. Step 3. Put the valve stem through the hole in the hubcap and attach the Velcro. Then pop the hubcap on the rest of the way. BOOM. Now you're ready to cruise with no worries. I've driven my Pontiac a few hundred miles with the hubcaps held on with the Velcro, and none of them have even come loose yet. Before, I couldn't go 10 miles without losing one. Your wheel & hubcap might be different ... Test this out on your crappiest spare first! So this little trick definitely works. Here's my understanding of why. As the car hits bumps, the tire and rim flex to a certain degree. The hubcap isn't attached to the rim as firmly as the tire, so the hubcap flexes less, and rotates just a little bit with each bump. A lot of times, if you look at your valve stem, you'll notice it's bent over because the valve stem hole has been creeping around. Now think about a strip of Velcro ... it's a lot easier to pull the two strips apart than it is to pull one strip sideways across the other. The Velcro holds well and prevents the hubcap from rotating in the rim (blue arrow), and eventually scooting its way outward and off (red arrow). So as long as the adhesive holds to your rim & hubcap, the Velcro will hold strong. Happy motoring!
