What Causes a Flat Spot on a Car Tire?
A flat spot on a car tire is caused by prolonged weight on the tire during periods of immobility.
The main causes of flat spots on car tires include:
1. Extended parking periods
2. Low tire pressure
3. Exposure to extreme temperatures
4. Poor alignment or suspension issues
5. Manufacturing defects
These factors highlight different aspects of tire maintenance and performance. Understanding these causes can aid drivers in preventing and addressing flat spots.
-
Extended Parking Periods: Extended parking periods can lead to flat spots on car tires. When a vehicle remains stationary for weeks or months, the weight of the car can compress the rubber in a specific area. The result is a flattened section on the tire, which can lead to uneven wear and handling issues. Research from the Tire Industry Association suggests that tires left stationary for as little as a month can develop flat spots, particularly in colder climates.
-
Low Tire Pressure: Low tire pressure contributes to flat spots on car tires. Insufficient air reduces the tire’s ability to maintain its shape when supporting weight. The Rubber Manufacturers Association states that tires should be inspected regularly, as driving on under-inflated tires generates additional heat and increases flat-spot risk. For example, if a tire is consistently maintained at below its recommended pressure, it may develop permanent flat spots.
-
Exposure to Extreme Temperatures: Exposure to extreme temperatures can cause flat spots on car tires. Heat may soften the rubber, while cold can make it rigid. A study by the Society of Automotive Engineers found that temperature fluctuations can alter tire performance and structure.

Can Flat Spots Develop From Extended Parking?
Yes, flat spots can develop from extended parking. This typically occurs when a vehicle remains stationary for a long period.
When a tire sits in one position for too long, the weight of the vehicle compresses the rubber at contact points with the ground. This can cause the tire’s shape to change slightly, resulting in flat spots. Extreme temperatures can exacerbate the issue. In colder conditions, the rubber hardens and becomes less flexible, making flat spots more likely. Regularly moving the vehicle or using tire cradles can help distribute the weight and prevent this problem.
Are Temperature Changes a Factor in Flat Spot Formation?
Yes, temperature changes can be a factor in flat spot formation on tires. Flat spots occur when tires remain stationary under weight, especially in cold weather. Extreme temperature shifts can harden the rubber, increasing the risk of these flat spots developing.
When comparing the effects of temperature on flat spot formation, it’s essential to consider both heat and cold. High temperatures can soften the tire rubber, making it more pliable and less prone to developing flat spots when the vehicle is parked for a short period. Conversely, low temperatures can harden the rubber. This rigidity during long periods of immobility can lead to flat spots, especially in winter months. For example, a vehicle parked for weeks in sub-zero temperatures may experience more significant flat spot issues than one stored in a heated garage.
The benefits of monitoring tire temperature include improved safety and performance. Proper temperature maintenance can prolong the lifespan of your tires and enhance their grip on the road. According to the Tire Industry Association, maintaining proper tire pressure and temperature can increase fuel efficiency by up to 10%, providing a financial incentive for vigilant tire care.
