Your vehicle’s frame and wheels have coil springs situated in between them. Whenever you pass by a bump or something other than a smooth surface, your car moves in an up and down motion since it bounces on said springs. Because bouncing is an unavoidable issue, your ride’s shocks (or struts) prevent it from continuously doing so, ensuring that you and your car remain connected to the road.
But like any other automobile component, these shock or bounce absorbers also have a limited life span. This is why you should know more about tire cupping, which is a common sign of worn shocks and/or struts. Old Town Shell explains the most important hows about this particular tire issue.
How to spot it
When assessing your tires for cupping, look out for hills and valleys in an alternating pattern. Cupped tires also typically have smooth patches in random places all over.
How it happens
Worn out shocks and/or struts no longer have the ability to prevent a vehicle from continuously bouncing. This then leads to the tires leaving the surface of the road, even if it’s just for a moment. And when it goes back down, the area that comes into contact with the road receives more force and pressure.
Not only does this leads to the gouging out of some portions of the rubber; it can also put you in a serious safety hazard.
Note that incorrect balance with your tires or wheels can also lead to this common tire concern.
How to deal with it
You can conduct a self-diagnosis for tire cupping since in most cases, it’s easy to determine the kind of pattern it comes with. However, you need to be very careful, as heel-toe wearing or feathering can exhibit the same symptoms, appearance wise.
It’s best that you have a professional mechanic take a closer, more experienced look at your tires since these people have a more in-depth knowledge of tire issues, including cupping.
