Why Do Flat Spots Occur When Parking for Extended Periods?
Flat spots on tires occur when a vehicle is parked for an extended period without movement. These flat spots are areas on the tire tread that become worn or flattened, leading to an uneven surface. This condition results in vibrations or a rough ride when the vehicle is eventually driven.
According to the Tire Industry Association, flat spots occur due to the weight of the vehicle pressing down on the tires in the same position over time. This pressure causes the tire rubber to deform and lose its original round shape.
The underlying causes of flat spots are primarily related to tire construction and the weight distribution of the vehicle. When a car is stationary, the tires experience constant pressure from the vehicle’s weight. Over time, this pressure can lead to a temporary or permanent deformation of the tire’s tread. Factors like temperature changes can exacerbate this issue, as cooler temperatures can make tire rubber more rigid, increasing the likelihood of flat spots forming.
Key technical terms include:
- Tire Deformation: This refers to the change in shape or structure of the tire caused by external pressures. In the context of flat spots, it means the tire loses its circular form and develops a flat area.
- Tire Tread: This is the part of the tire that comes into contact with the road surface. It is designed to provide traction and stability.
The mechanisms involved in flat spot formation include:
- Weight Pressure: The constant weight of the vehicle compresses the tire rubber. This sustained pressure prevents the rubber from returning to its original form.
- Material Properties: Tires are made of rubber compounds that can harden or become more pliable depending on temperature and time. Hard rubber is less responsive and can more easily form flat spots.
Specific conditions that contribute to flat spots include:
- Long-Term Parking: Vehicles left stationary for weeks or months are more susceptible to developing flat spots.
- Temperature Variations: Cold weather can stiffen the rubber, making it more prone to flat spots.
- Under-Inflation: Tires that are not properly inflated are more likely to deform under the weight of the vehicle.
For example, a car parked in an unheated garage during winter months may develop flat spots if left unattended. Similarly, a trailer parked for the entire camping season can present similar issues if the tires are not regularly rotated or moved.
