What causes rear tires to cup?
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 front tires to scallop?
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.
How can you tell if your tires are cupped?
The most noticeable signs of cupped tires are a scalloped treadwear pattern and noise. The tread looks like it was scooped in 3- to 4-inch bits all across the tire, in the middle, or on the edge. This is a result of the wheel bouncing, which means the tire doesn’t touch the surface evenly.
Do I need to replace cupped tires?
TOM: Unfortunately, it’s really not safe to drive on cupped tires. They have indentations in them. So every time the tire rotates, there are high spots that aren’t touching the road. But if they’re not, you want to replace them too, before you cup another set of tires.
Will an alignment fix tire cupping?
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.
Can over inflated tires cause cupping?
Typically no, but over inflated tires will cause the area of cupping tires to shift to the center of the tire. An over inflated tire will wear down more heavily in the center of the tread.
What causes tires to dip in the middle?
If your tires are wearing down rapidly in the center of the tread, you may be driving on tires that are consistently over-inflated. When your tires are filled over the recommended pressure, they’ll ride along the center of the tread”this makes the center of the tread wear down much faster than the rest of the tire.
Is tire cupping covered under warranty?
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.
What causes high and low spots on tires?
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.
Why are my front tires wearing out so fast?
Wheel Alignment This is the most common culprit when it comes to tires wearing out unevenly. If your wheel alignment is off, then the individual wheels and tires are taking different levels of stress as you drive.
Why are my 2 front tires wearing out so fast?
Lack of tire rotation Not rotating your tires in a timely manner can cause two of your tires to wear faster than the other two. On a front wheel drive vehicle, the front end of your car is heavier than the back end, Your front wheels are also the “drive wheels”, meaning they pull the car down the road.
Should your better tires be on the front or back?
According to Tire Review, new tires should always go in the back. Although new front tires will spread water and maintain traction, worn tires in the back will hydroplane and may cause the vehicle to spin out, says Tire Review. This is the same for vehicles with rear-, front- or all-wheel drive.
Which front tire wears faster?
Front tyres tend to wear faster, up to 2.5 times faster on some cars. The left front tyre has it the hardest. It is the most heavily loaded and responsible for transmitting most of the steering during right hand turns.
