Why Do Tire Shops Over Inflate Tires

Tire shops overinflate tires to prevent damage during storage or when exposed to temperature fluctuations. This practice helps maintain tire shape and prevents flat spots.

Maintaining proper tire inflation is important for vehicle safety and performance. However, some tire shops may overinflate tires for various reasons. Understanding why tire shops overinflate tires can help drivers make informed decisions when it comes to tire maintenance. We will delve into the reasons why tire shops may overinflate tires, the potential impact on tire performance, and how drivers can ensure their tires are properly inflated for optimal safety and longevity.

Let’s explore the topic further to shed light on this common practice in tire shops.

Benefits Of Over Inflating Tires

When it comes to maintaining your vehicle, proper tire inflation is crucial for safety and performance. While it’s commonly known that underinflated tires can be detrimental, overinflating tires can surprisingly offer certain benefits. Let’s delve into the advantages of overinflating tires and why tire shops may prefer this approach.

Improved Fuel Efficiency

Over inflating tires can lead to improved fuel efficiency. The reduced rolling resistance of overinflated tires allows the vehicle to use less energy to move, resulting in increased fuel economy. With less drag on the road, the engine doesn’t have to work as hard, contributing to better gas mileage.

Enhanced Tire Performance

Over inflating tires can also improve tire performance in several ways. It can lead to better handling and cornering, as the reduced flexing of overinflated tires provides a more stable contact patch with the road surface. Additionally, overinflation can help prevent irregular tread wear and improve the overall lifespan of the tire.

The Risks Of Over Inflating Tires

Tire shops occasionally over inflate tires, which can expose drivers to various risks. This practice may lead to decreased traction, uneven tire wear, and a higher chance of blowouts. It’s important to regularly check and maintain proper tire pressure for a safer driving experience.

Over inflated tires can lead to various hazards on the road. Excessive tire pressure can cause problems such as uneven wear and tear and reduced traction. Let’s delve into these dangers.

Uneven Wear And Tear

Over inflation can result in uneven tread wear. This can compromise the tire’s lifespan and overall performance.

Reduced Traction

Excessive tire pressure may reduce the tire’s contact patch with the road. This diminishes traction and handling, especially in wet or slippery conditions. Maintaining proper tire pressure is crucial for safe driving and the longevity of your tires.

Understanding Tire Pressure

Recommended Tire Pressure

Recommended tire pressure is the ideal inflation level specified by the vehicle manufacturer.

  • Helps ensure safe driving
  • Improves fuel efficiency

Understanding Psi

PSI stands for pounds per square inch, the unit of measurement for tire pressure.

  • Indicates the pressure exerted on the tires
  • Varies based on vehicle make and model

Why Tire Shops Over Inflate Tires

When you visit a tire shop, you may notice that the tires on your vehicle are often inflated to a higher pressure than recommended by the manufacturer. This practice may seem confusing, but there are good reasons why tire shops overinflate tires.

Prevent Tire Flat Spots

Overinflating tires can prevent flat spots, which can occur when a vehicle sits for an extended period. This is particularly common in seasonal vehicles like RVs or classic cars. By increasing the tire pressure, shops aim to reduce the risk of flat spots forming, ensuring that your tires remain in good condition during periods of inactivity.

Mitigate Pressure Loss During Storage

During storage, tires can naturally lose air pressure over time. By overinflating tires, tire shops mitigate the effects of pressure loss, helping to ensure that your tires remain at the recommended pressure when you return to retrieve your vehicle. This also helps to prevent potential damage to the tires due to underinflation.

How To Properly Maintain Tire Pressure

Regularly checking and maintaining the proper tire pressure is essential for optimal vehicle performance and safety. In this section, we will explore the key steps to ensure your tires are inflated correctly and offer guidance on following the manufacturer’s recommendations.

Regularly Check Tire Pressure

To keep your tires in top condition, it’s important to regularly check their pressure. Ideally, you should inspect the tire pressure at least once a month. This will help you identify any deviations and take prompt action to rectify them.

You can easily check the tire pressure using a tire pressure gauge, readily available at most gas stations and auto supply stores. Simply remove the valve cap, firmly attach the gauge to the valve stem, and note the reading displayed. Compare this reading to the recommended inflation pressure specified in your vehicle’s manual or the sticker located on the driver’s side door jamb.

When inflating the tires, ensure they are cold, as heat from driving can increase the pressure and provide an inaccurate reading. If the pressure is below the recommended level, use an air compressor to add air until the desired pressure is achieved. On the other hand, if the pressure is too high, release air gradually until it reaches the correct level.

Follow Manufacturer’s Recommendations

Manufacturers provide specific recommendations for tire pressure to ensure optimal performance and safety. These recommendations can vary based on factors such as tire size, vehicle weight, and intended use.

It’s crucial to adhere to the manufacturer’s guidelines when inflating your tires. Failure to do so may result in poor handling, reduced fuel efficiency, and increased risk of tire damage or blowout. Following the manufacturer’s recommendations will not only ensure your safety but also extend the life of your tires.

Take note that the recommended tire pressure may differ between the front and rear tires, especially in vehicles with varying weight distributions. Therefore, it’s important to verify the correct pressure levels for each tire to maintain balanced performance.

In conclusion, maintaining proper tire pressure is vital for your vehicle’s performance and safety. Regularly checking the tire pressure and following the manufacturer’s recommendations will help you achieve consistent and optimal inflation levels. By doing so, you can enjoy a smoother ride, maximize fuel efficiency, and increase the longevity of your tires.

Frequently Asked Questions For Why Do Tire Shops Over Inflate Tires

Why Do Auto Shops Over Inflate Tires?

Auto shops may overinflate tires to compensate for potential pressure loss. This can prolong the time between refills and reduce the chances of underinflation-related issues.

Are New Tires Supposed To Be Overinflated?

New tires should not be overinflated as it can cause uneven wear and affect performance. Follow the manufacturer’s recommended tire pressure for optimal safety and longevity.

Is 40 Psi Too High For Tires?

Maintaining 40 PSI in tires is generally safe, but it may cause a harsh ride. Always follow the manufacturer’s recommended tire pressure.

Is 2 Psi Over Too Much?

Increasing tire pressure by 2 PSI should be fine as long as it doesn’t exceed the maximum specified by the manufacturer. It can enhance fuel efficiency and vehicle handling. However, exceeding the recommended limit may cause uneven tire wear and compromise safety.

Why Do Tire Shops Over Inflate Tires?

Over-inflating tires is done to compensate for pressure loss over time and provide better fuel efficiency, stability, and handling.


Tire shops may overinflate tires due to inexperience or lack of proper equipment. It’s important to communicate with the technician and monitor tire pressure regularly to ensure safety and performance. Understanding the reasons behind overinflation can help prevent potential issues and prolong the lifespan of your tires.

Always prioritize proper tire maintenance for a smoother and safer driving experience.
