Ways to Prevent Back Tires Cupping Make sure none of your tires lose air more than the others and check their pressure every week. Rotate your tires regularly. Rotation every 5,000-8,000 miles will prevent tire-related causes of back tire cupping, plus other types of uneven wear. Buy new tires in time.

cupping and scalloping are almost always caused by shocks that are going bad.

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.

The cause of tire cupping can vary, but if it’s not too severe it can be fixed.

Yes! Cupping tires can be very dangerous. When your tires are cupping, the tire is not making constant contact with the surface of the road due to bouncing. This contact then loss of contact will happen many times per second as the wheel spins.

Tire cupping is an uneven wear pattern, which occurs due to irregular up-and-down motions of a wheel (bouncing). Cupping, also known as tire scalloping, refers to when a car or truck’s tire tread moves from high to low in random spots.

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.

A cupped tire will make a similar noise to that of a bad wheel bearing. Tire cupping noise will sound like a humming or roaring coming from either the front or the rear of your vehicle. The noise depends on the affected tire and or wheel bearing.

Tires make strange noises when they are low or damaged. Second needs to be the brakes. A bad brake, warped caliper or rotor, or issues with the parking brake can all cause noises related to the tires rotating. Look for a dragging or damaged brake pad or shoe, and inspect all hardware.

Cupped or feathered tires would not cause death wobble, but they would cause some pretty bad vibrations and shimmies. They could trigger death wobble if something else was up with your front end.

The Warning Signs Of Worn Shocks And Struts The movement may be slight, but you notice it. Vehicle “tips” to one side in turns. When taking a sharp turn or an off-ramp, your vehicle leans or “tips” to the outside of the turn and feels wobbly. The front end dives more than expected during hard braking.

Death wobble is often blamed on a failed steering stabilizer or shocks and struts. Worn tie rods, idler arm, track bar, wheel bearings, pitman arm, steering center link and shaft, ball joints, alignment and even tire pressure can combine to cause the death wobble.

4 Signs of Worn Shocks and Struts

1. The Vehicle Bounces. Coil springs are responsible for dampening the transfer of energy when a vehicle drives over bumps, potholes and uneven roads.
2. The Front End Dives and/or the Rear Squats.
3. The Vehicle Exhibits Signs of Body Roll.
4. You Hear Unusual Noises.
