Why are my rear tires 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.
What causes tires to cup on the inside?
Tires cup on the inside due to severe suspension issues. More rarely, such a pattern is caused by bad wheel bearings, loose ball joints, damaged control arm or steering linkage. You need to go to a repair shop and run a full diagnosis on the suspension and other parts that connect the wheel to the car.
Will cupped tires fix themselves?
Provided that you’ve replaced the worn shocks, bushings or relevant suspension component, driving on a cupped tire will eventually smooth it out to some extent. Considering the likelihood and consequences of tire failure after cupping, you’re best off replacing the cupped tire sooner rather than later.
What causes cupped or scalloped tires?
Cupped or scalloped dips appearing around the surface of the tire tread wear could indicate loose, worn or bent suspension parts. Shocks and struts are the most likely culprit because they provide damping force to control tire movement. When the tires move excessively, the scalloped pattern can appear.
What to do if tires are cupping?
Is It Possible To Repair Tire Cupping?
- Park the vehicle and put it on the emergency brake.
- Find the cupped tire by looking at the tread of all four tires.
- Push on the vehicle and see how much it bounces, and if it does considerably, the shocker absorbers are most likely the main issue.
What do cupped tires feel like?
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.
How big are the tires on a VW Alltrack?
Alltrack’s tire size is a pretty rare size, so as this VW model comes in for its first round of tire replacement, there will be a little bit of Googling, hair-pulling and general head-scratching while owners look to source 205-55-17 tires.
Why are Alltrack tires so hard to find?
I’ll put it simply: Alltrack tires are hard to find because of the size. I chose a favorite tire — Continental ExtremeContact DWS — over the “correct” factory tire specs because I value something I know over getting the specs right.
Why are the treads on my back tires cupping?
If even one setting is slightly out of alignment on the rear wheels of a front-wheel drive car, the tread will cup. Back tire cupping also occurs when the front and rear tires aren’t parallel to each other, or if the toe angles are misaligned. In this case, wear will be diagonal around the whole tread.
How often do you need to replace a cupped tire?
When any small part of that system is bent or worn, it becomes loose, allowing the wheel to bounce. Aside from a bumpy ride, such an issue also causes cupped tires. Shock absorbers have to be replaced every 50,000-60,000 miles, struts every 60,000-90,000 miles. Suspension bushings have a longer lifespan – 100,000-150,000 miles.
