A: In many cases you can, but it’s easier with the wheel off. A socket and simple prying tool can help seat or remove caps without damage.
Q: Are chrome center caps worth the extra cost?
A: If aesthetics matter or you’re upgrading a show-trailer, chrome caps provide a premium look and corrosion resistance. For rough, utilitarian use, a budget cap can perform just as well.

A: Check the product specs for EZ Lube compatibility. Many caps list this clearly; if in doubt, consult the manufacturer’s fitment guide or contact support.
Q: How many dust caps should I buy?
