What is Tire Cupping?

Tire cupping, also known as scalloping, occurs when the tread on your van’s tires wears unevenly, resulting in wavy, bumpy, or scalloped patterns. This irregular wear can cause increased road noise, noticeable vibrations, and decreased tire lifespan.

Common Causes of Tire Cupping in Vans

Tire bouncing due to worn suspension.

  1. Suspension Issues: Worn or damaged suspension components can cause the tires to bounce and make inconsistent contact with the road, leading to cupping.

  2. Imbalanced Tires: If your tires are not properly balanced, they may rotate unevenly, causing irregular wear patterns.

  3. Wheel Misalignment: Misaligned wheels can lead to uneven pressure distribution across the tire surface, increasing the likelihood of cupping.

  4. Poor Tire Maintenance: Neglecting regular tire rotations and proper inflation can accelerate tire cupping.

  5. Road Conditions: Driving frequently on rough or uneven surfaces can contribute to cupping, especially for heavily loaded van conversions.

How to Prevent Tire Cupping

  1. Regular Suspension Inspections: Ensure that your van’s suspension system is in good condition and address any worn components promptly.

  2. Wheel Balancing: Have your tires balanced regularly to ensure even wear.

  3. Proper Wheel Alignment: Align your wheels periodically to maintain even tire contact with the road.

  4. Tire Maintenance: Rotate your tires every 5,000 to 7,000 miles and maintain proper tire pressure.

  5. Driving Habits: Avoid aggressive driving and try to steer clear of consistently rough terrain when possible.
