Brand New Tire Losing Air Pressure: Causes & Fix

Nothing is more annoying than spending money on a brand-new pair of tires only to discover they are losing air pressure soon after being put on. Tire pressure that suddenly drops not only impairs your driving experience but also casts doubt on the tire’s durability and safety.

To maintain optimum performance and road safety on the road, you must know what causes a brand-new tire to lose air pressure and how to repair it quickly. This tutorial examines the numerous reasons why a brand-new tire might lose air pressure, as well as provides practical solutions.

Common Causes of Brand New Tires Losing Air Pressure

The following are some of the main reasons why your brand-new tire is losing air pressure.

Poor Bead Seating

Improper bead seating is one of the main causes of air loss in new tires. The inner tire edge known as the bead creates an airtight seal with the wheel rim. Air leakage may result from improper tire bead seating during installation. Dirt, rust, or a lack of lubrication between the tire and the rim might prevent the bead from seating properly.

Defective Valve Stem

The valve stem acts as the tire’s point of entry for adding or releasing air. Tire pressure might decrease as a result of air slowly leaking out of a defective or damaged valve stem.

Tire Puncture

Even completely new tires can be punctured during transportation, storage, or installation. A puncture in the tread, such as one caused by a nail or other sharp object, can cause a steady leak of air and a gradual loss of tire pressure.

Wheel Rim Damage

Defects to the wheel rim, such as dents or bends, can allow air to escape from the tire. If you plan on installing new tires, you should check to see if the wheel rims are corroded before you mount them.

Tire Manufacturing Defects

Even though they are uncommon, tire manufacturing flaws can cause air loss in brand-new tires. If the construction, materials, or quality control of the tire are poor, the integrity of the tire may be compromised, and air leakage can occur.

Temperature Fluctuations

Significant temperature swings might have an impact on tire pressure. It is common for tire pressure to decrease in colder climates while increasing in warmer climates. When the temperature changes, tires that were inflated with air at a different temperature may lose or gain pressure.

Over-Inflation During Installation

The tires can lose air if they are overinflated during installation. In overinflated tires, the extra force can gradually lower the pressure by forcing air out.

Sidewall Damage

Any damage to the sidewall, such as cuts, bulges, or impact damage, can cause the tire to lose air.

Fixing a Brand New Tire Losing Air Pressure

You can prevent your brand-new tire from losing air pressure by following these tips:

Check Bead Seating

If the tire bead is not correctly installed, the tire and rim may not create an airtight seal. Make sure the tire’s bead is properly seated against the rim by totally deflating it before re-inflating it. If special lubricants or bead sealers are required, a qualified tire technician can use them to produce the desired seal.

Inspect the Valve Stem

Make sure the valve stem is not damaged or worn. Replace the defective valve stem with a new one. To avoid air loss, make sure the valve cap is securely fastened.

Patch Punctures

It is crucial to fill a hole in the tire as soon as possible. A qualified tire technician can effectively fix the majority of punctures using techniques that have been approved by the industry.

Inspect the Rim

Pay close attention to the wheel rims for any indications of corrosion or deterioration. To ensure an airtight seal, have the rims fixed or replaced if they are broken.

Address Manufacturing Defects

Get in touch with the tire manufacturer or the retailer where you bought the tires if you think they may have a manufacturing defect. They will assist you with the warranty procedure and perhaps offer a replacement or refund if the fault is confirmed.

Consider Temperature Adjustments

Bear in mind that temperature variations might have an impact on tire pressure. You should adjust tire pressure if you notice air loss due to temperature changes.

Seasonal Tire Pressure Adjustments

As the seasons change, so does the ambient temperature, affecting tire pressure. During the transition from winter to summer, or vice versa, it’s essential to adjust the tire pressure accordingly. Colder temperatures can cause tire pressure to drop, while warmer temperatures can lead to increased pressure. Refer to the vehicle manufacturer’s guidelines for recommended tire pressure adjustments based on seasonal changes.

Check for Over-Inflation

Make sure the tires are inflated to the manufacturer’s recommended pressure. Make sure the tire is not overinflated. To prevent air loss, avoid overinflating the tires.

Address Sidewall Damage

The sidewall of the tire must be replaced if it is damaged. If sidewall damage is not repaired, it could cause the tire to blow out structurally.

Checking Tire Pressure Manually

While TPMS is an excellent tool for monitoring tire pressure, it’s essential to complement it with manual checks using a tire pressure gauge. TPMS can only detect significant changes in tire pressure, whereas manual checks allow for more accurate readings. When checking tire pressure manually, ensure the tires are cold, as driving heats the tires and increases the pressure, potentially giving inaccurate readings.

Seek Professional Tire Inspection

If you experience persistent air loss in your brand-new tires despite performing regular maintenance, it’s essential to seek a professional tire inspection. A trained technician can identify underlying issues that may not be visible to the naked eye and provide appropriate solutions.

Tire Pressure Monitoring Systems (TPMS)

Tire Pressure Monitoring Systems (TPMS) are a standard feature in contemporary vehicles. The TPMS continuously monitors tire pressure and informs the driver if there is a substantial pressure drop. TPMS is a valuable safety feature that helps drivers stay informed about their tire’s condition and ensures timely action in case of air leakage. If your brand-new tire is losing air pressure, the TPMS warning light may be your first indication of the issue. When the TPMS light illuminates, it’s crucial to check the tire pressure immediately and address any problems promptly.

Importance of Proper Wheel Alignment

Proper wheel alignment is crucial for tire performance and longevity. Misaligned wheels can cause uneven tire wear and affect the tire’s contact with the road. The improper alignment of a vehicle can increase friction, increase heat buildup, and accelerate air loss. Regularly checking and correcting wheel alignment can help prevent excessive tire wear and air leakage.

Prevention Tips for Maintaining Proper Tire Pressure

The following tips will help you maintain the proper pressure of your tire:

  •       Regularly Check Tire Pressure: Make it a habit to check the tire pressure at least once a month and before long drives. Properly inflated tires not only ensure safety but also contribute to better fuel efficiency and tire longevity.
  •       Inspect Tires for Damage: Regularly inspect your tires for any signs of punctures, cuts, or damage to the tread and sidewall. Promptly address any issues to prevent further damage and air leakage.
  •       Choose Quality Tires: Invest in high-quality tires from reputable brands. Quality tires are less likely to experience air loss due to manufacturing defects or other issues.
  •       Professional Installation: Have your tires installed by a professional tire technician who can ensure proper bead seating and correct tire inflation.
  •       Install Valve Caps: Always use valve caps on the valve stems to protect them from dust and debris, which can cause air leakage.
  •       Proper Tire Storage: If you store your spare tires or seasonal tires, keep them in a cool, dry place away from direct sunlight. Store them vertically and check their condition before reinstallation.

On a Concluding Note

Experiencing air loss in a brand-new tire can be a frustrating and concerning situation. Various factors, such as poor bead seating, tire punctures, defective valve stems, and temperature fluctuations can contribute to this issue. By understanding the common causes and implementing proper maintenance practices, you can address the problem effectively and maintain optimal tire performance and safety.

If you encounter air loss in your brand-new tires, inspect the bead seating, valve stem, and tire condition. Patch punctures, address sidewall damage, and ensure proper tire inflation to prevent air leakage. Regularly check tire pressure, choose quality tires, and rely on professional installation to minimize the risk of encountering this issue in the future.
