The proper way is to remove the tire and wheel, inflate the tire to the manufactures specified pressure as stated on the tire, submerge the tire/wheel into a water bath to locate the leak, inscribe a mark on the wheel to indicate the leak areas, inscribe a mark on the tire at the valve stem to indicate the orientation of the tire to the wheel, remove the tire, scuff the inside of the rim surface at the leak area, use general purpose cleaner to clean the leak area, apply 3 mm (0.12 inch) thick layer of adhesive/sealant to the leak area, allow for the adhesive/sealant to dry, align the inscribed mark on the tire with the valve stem, install the tire, inflate the tire to the manufactures specified pressure, submerge the tire/wheel into a water bath in order ensure the leak is sealed, balance the tire and wheel, and install the tire and wheel.

You must not heat wheels in an attempt to soften them for straightening or repair damage from striking curbs, etc., and must not weld wheels. The alloy used in these wheels is heat-treated and uncontrolled heating from welding affects the properties of the material.

The use of tubes in tubeless tires is not a recommended repair because speed ratings are greatly reduced.

Aprotective clear coating covers the surface of the original equipment's cast aluminum wheels. Surface degradation may develop if frequent automatic car wash cleaning wears off the factory-applied protective clear coating.
