How we handle alloy wheel refurbishment at Hackbridge
Assessment happens with the tyre off, which is the only way to see the inside of the rim. Corrosion on the bead seat is the usual reason a wheel loses a few psi a week, and it is completely invisible with a tyre fitted. The barrel is checked for cracks, particularly around the spoke junctions and the valve hole, and each wheel is checked for runout rather than eyeballed, because a buckle large enough to be felt through the steering is usually far too small to see.
Preparation decides how long the finish lasts. Where the old coating has lifted it comes off back to clean metal rather than being feathered and sprayed over, because paint or powder laid across corrosion lifts again from the same edge within a year or two. Diamond cut wheels bring a further decision at this point. Machining takes material off the face every time it is done, so a wheel already cut more than once may not have enough left to take another pass, and we will say so rather than removing metal from a wheel that then has to be replaced.
You choose the finish before anything is stripped, gloss level included, because a satin black and a gloss black in the same colour look like different wheels once they are on the car. Wheels are photographed as they arrive, tyres go back on with the sensors checked, each wheel is balanced, and everything is tightened to the torque figure for your car. We will not cosmetically refinish a cracked wheel and we will not weld one for road use. If a wheel fails the inspection you hear about it before any work starts, and you have lost nothing.
