How Long Can Wheel Hub Paint Last Without Peeling?
3 Answers
Wheel hub paint can last for about half a year. Below is a partial introduction regarding automotive tire dynamic balance: Main reason: A car wheel is an assembly consisting of a tire and a wheel hub. Due to manufacturing factors, the mass distribution of various parts of this assembly is not uniform, which leads to dynamic imbalance when the wheel rotates at high speeds. The driver will feel significant steering wheel vibration. Solution: The most effective method is to add counterweights to the wheel under dynamic conditions to correct the balance at various edges of the wheel. Other reasons: Shock absorber failure, frame deformation, excessive meshing clearance of the main and driven gears of the final drive, etc.
Last time when helping a friend with wheel hub painting, I specifically asked the technician. How long this job lasts really depends on several key factors. The painting process needs to be solid - three layers of primer, three layers of color paint, and then three layers of clear coat is the most reliable. Like my car which was baked in a high-temperature curing booth, it hasn't peeled for four to five years. You need to be careful when washing the car - avoid strong alkaline cleaners, especially in the first three months after painting. My neighbor went for a cheap option at a roadside shop, and the paint chipped after just two highway runs during rainy season - now the rims look like they have psoriasis. If you're driving through construction sites or coastal areas daily, even the best paint won't withstand erosion from gravel and salt. It's best to choose neutral tire wax, as inferior wax can really corrode the paint surface.
I've tried three wheel color modification solutions, and baked paint is the most durable. Right after spraying, it should feel as smooth as ceramic glaze, and this type of paint layer isn't afraid of asphalt. The biggest fear is wheel deformation from hitting curbs. Last winter, my car ran over a frost heave bump, and the wheel rim directly chipped off a piece of paint. In summer, avoid blasting the wheels with high-pressure water when washing the car, especially on hot brake discs, as thermal expansion and contraction can cause the paint to crack. Last time, the 4S shop mentioned that unstable tire pressure can also accelerate paint cracking, so remember to check the tire pressure monthly, ensuring the error doesn't exceed 0.3 bar. Usually, park away from green belts, as tree sap is harder to clean than bird droppings. With normal use, it should last four to five years without issues.
