Tire Wear and Alignment Issues

The video tutorial discusses various factors affecting tire wear, including inflation pressures, alignment errors, and wheel imbalance. High inflation pressures lead to center wear, while low pressures cause shoulder wear. Alignment issues like camber and toe angles contribute to both inside and outside tire wear. Turning angles and caster can also affect wear patterns. Cupping is often due to wheel imbalance or suspension issues.

What is a consequence of excessively high inflation pressures on tires?

• Reduced tire lifespan

• Improved traction

• Center of the tire carries most of the load

• Increased fuel efficiency

Which alignment error can cause outside tire wear?

• Low inflation pressure

• Toe-out condition

• Excessively positive camber

• Excessively negative camber

What does a toe-in condition contribute to?

• Inside shoulder wear

• Outside tread wear

• Even tire wear

• Cupping wear patterns

What alignment error can lead to inside shoulder wear?

• Excessively positive camber

• High inflation pressure

• Toe-in condition

• Excessively negative camber

Which condition can cause both shoulders of a tire to wear excessively?

• High inflation pressure

• Low inflation pressure

• Balanced wheel alignment

• Proper camber angle

What can large turning angle errors lead to?

• Improved cornering

• Rapid shoulder wear

• Even tire wear

• Reduced tire noise

What can excessive positive caster cause?

• Balanced wheel alignment

• Excessive camber roll

• Improved straight-line stability

• Reduced tire wear

What is a potential cause of cupping wear patterns on tires?

• Proper inflation

• Correct alignment

• Wheel imbalance

• New suspension components

What effect does excessive wheel imbalance have on tires?

• Improved fuel efficiency

• Hopping at freeway speeds

• Even tire wear

• Reduced road noise

Which component's condition can contribute to cupping wear patterns?

• New tires

• Worn suspension components

• Properly aligned wheels

• Balanced tires
