Protect tandem tires from sun and weather with covers made for double axle setups. Measure your tire diameter and check the gap between tires; if your axle spacing is longer than usual, go with single-wheel covers instead. For a snug fit in wind, secure them with straps or bungees, and take a moment during installation to set the height for drainage and airflow.
Not always. Some are sold for one side only, so confirm the quantity to cover both sides of your trailer. If no strap or bungee is included, plan to use your own through the rear grommets to secure them.
Use the grommets to draw them tight and add bungee cords for extra hold. Some sets don't include bungees, so plan to supply your own. Covers can loosen in the sun, so recheck tension after they've been on a while. In storms, unsecured covers can blow off, so strap them down.
Measure your tire diameter and pick a cover that matches the listed range. Check the gap between your tires; a 6" or less gap is typically needed for a good Double Axle fit. If your tandem spacing is long, like around 42" on-center, use single covers instead. Set the cover slightly off the ground to help drainage and airflow, and snug it with the grommets.
They help protect tires from sun, but in strong sun some covers stained and became brittle after a couple of years. Inspect seasonally and replace if you see cracking or tearing. Keeping a snug fit with the grommets and bungees can help them sit better over time.
Often no. If the gap between tire treads is more than 6" or your axles are about 42" on-center, Double Axle covers can fit weird or loose. In that case, use individual covers for each tire. Measure center-to-center spacing and tire diameter before choosing.
