Cupping of tires indicates many of things depending upon where the cupping is. Center tread cupping is a sign of under inflation or bad shock absorbers while cupping on the edges can indicate bad wheel bearings, bad ball joints or bad steering.
Yes, it can but cupping can also have other causes. Over inflated tires can tend to bouce more, especially when combined with weak/worn shocks or struts. When tires bounce cupping can occur when the tires strike the road. Cupping can also be caused by the tire/wheel assembly being out of balance (which can also cause the tires to bounce). Cupping is just one of several types unusual wear on tires.
Bad shocks, ball joints bad, tires out of balance. More then likely shocks.
Yes, cupping is caused by defective shocks/struts.
Assuming you mean wear of the edges of the tires, and not the middle, this is an issue of UNDER inflation of the tires.
A tire cupping can be caused by tread being lost. A tire cupping means that it should be replaced as soon as possible. You do not want a cupping tire to be used while you are driving. Air can escape and cause a flat.
Cupping causes blood to be drawn to the surface of the skin, which can cause red marks, swelling, and bruising.
Check the tires for cupping. If you have had an alignment problem the tires could be cupping and will make quite a lot of noise. It could also be a wheel bearing.
make sure that the tires are all properly inflated. If they are, then you may need to have the front end aligned.
Improper rotation or worn shocks or struts
Hey Bob==Ever since 1982 tires have had a tendency to cup and I really don't know of what causes it. I have heard all kinds of diagnoises but none that I find are true. Some brands of tires are worse about cupping than others. I think the manufacturers changed the rubber compound formula but I can't get any one to admit to that. Rotate the tires every 7ooo miles and make sure they are balanced is all I can say. GoodluckJoe
Cupping is caused by lack of regular tire rotation and proper air pressure. Check the owner's/service manual for frequency of tire rotation and correct air pressure for your vehicle.
Tire cupping can be caused by worn out shocks or struts, weak springs, bad wheel bearings, loose parts, defective tire, or a tire out of balance.
