Will these fit my vehicle's tire valves?

The 45MM size fits standard tire valve stems found on most vehicles. If your valves are oversized or custom, measure your stem diameter before ordering to confirm fitment.

Do these caps need any prep or painting?

These come finished in purple and ready to install as-is. No painting or prep work required.

Will the purple color fade over time?

Polyurethane holds color well under UV exposure, but like any exterior trim, extended sun exposure will gradually lighten the finish. Applying a UV protectant spray periodically extends color vibrancy.
