How to Fix Tire Cupping
Suspension components like shock absorbers, struts, bushings and others wear out with miles travelled. The result can be a tire that is no longer able to roll smoothly down the road; instead, it bounces slightly. This bouncing creates uneven points of pressure on tires, leading to tire cupping.
Tire Noise: You may notice a rhythmic sound, louder than your usual road noise, if your tires are cupped. This is due to those unevenly worn patches of tread rubber causing odd noises while rolling. Vibrating or Shaking: You may feel some excessive vibrations either in the steering wheel or in your seat as you drive.
Tire cupping can be the result of either poor vehicle alignment, manufacturing defect, or improper inflation. Tire cupping causes may vary also. If the cupping is not that severe, you could still fix it.
Uneven tire wear – When your vehicle’s shocks and struts are worn out, the car can bounce, causing a reduction in road holding force. This bouncing can also cause accelerated tire wear including cupping or scalloping of the tires (when pieces of rubber are gouged out of the tire).
cdu8 said: Only if it’s caused by some fault of the car and not just bad alignment or tires. I had cupping on my left front tire. Dealer found the cause was a worn strut and replaced it under warranty.
If the tires are “cupped” or have high and low spots (particularly on the outer areas), that is a possible indication that the tires may need to be rotated more frequently, the shocks or struts are worn, the tires are out of balance, or unusual road conditions or driving habits are present.
Many car tires come with a prorated mileage warranty, also called a tread-life warranty, that is often used as a selling point. Think of that mileage limit, generally somewhere between 30,000 and 100,000 miles, as a figure highly influenced by a marketing department.
The straightforward answer is “it depends.” A normal set of tires should last for 60,000 to 75,000 miles, or about four to five years. But there are a few key factors that will affect your tires’ lifespan. Keep scrolling to learn more.
If your new car came with a set of Michelins, Michelin made the tire but they made it to the specifications set by your car manufacturer. These tires are referred to as OEM (original equipment manufacturer). This is because virtually all auto manufacturers specify very soft rubber which means they wear out too fast.
“Warranty coverage provides protection on replacement cost. You may be able to get the coverage you want bundled in with the tires. In some cases, such as when you get a great deal on tires themselves, but they do not include a road hazard warranty, it may be worth paying extra for that protection.”
$250 per tire, $1,000 maximum per Service Contract period. Covers the cost of wheel repairs up to $150 or if non-repairable, the cost to replace a damaged wheel(s) up to $500 per wheel, $2000 per Service Contract period.
