Tires are essential to a vehicle’s traction, steering, and braking performance. As they wear and age, their ability to maintain contact with the road can change, particularly in wet conditions.

Regular inspections help drivers recognize when maintenance or replacement is necessary.

<h3>Check the Tread Depth</h3>

Tread grooves help channel water away from the tire’s contact surface. As the tread wears down, wet-road traction can decrease, making tread depth an important part of routine maintenance.

Most passenger tires have raised wear indicators within the main grooves. These indicators correspond to a tread depth of approximately 2/32 of an inch (1.6 mm). When the surrounding tread becomes level with them, the tire has reached its minimum tread limit and should be replaced.

Use a tread-depth gauge to measure wear accurately. Check several points across each tire because the inner edge, center, and outer edge may wear at different rates.

<h3>Inspect the Sidewalls</h3>

Sidewalls support the tire’s structure and flex during driving. Examine them for cracks, cuts, bulges, or other visible damage.

Minor surface cracking can develop with age, but deeper cracks may indicate deterioration. A bulge can signal damage to the internal structure, while a deep cut that exposes internal cords requires immediate attention.

A tire with a bulge, exposed cords, or suspected structural damage should be removed from service and assessed for replacement. Avoid driving on a visibly damaged tire.

<h3>Investigate Persistent Vibration</h3>

Vibration through the steering wheel, seat, or vehicle body may indicate wheel imbalance, uneven tire wear, wheel damage, or an internal tire defect.

Balancing can resolve vibration caused by an imbalance. If the problem persists, a qualified technician should inspect the tires, wheels, and related components to identify the cause and recommend the appropriate solution.

<h3>Consider Tire Age</h3>

Tires deteriorate over time, even when their tread appears adequate. Environmental exposure, storage conditions, temperature changes, and normal use can affect their materials.

The manufacturing date is recorded in the tire identification code on the sidewall. Check the code and consult the tire manufacturer’s recommendations for age-related inspections and replacement.

Some manufacturers recommend replacing tires after approximately six to ten years, regardless of remaining tread. Recommendations vary, so follow the guidance applicable to your tires and arrange professional inspections as they age.

<h3>Identify Uneven Wear</h3>

Uneven tread wear can indicate incorrect inflation, alignment problems, or issues with suspension components. The pattern offers useful clues about the maintenance required.

<b>Common tread wear patterns</b>

- Wear along one edge: May indicate an alignment issue or incorrect wheel positioning.

- Excessive center wear: Can be associated with overinflation.

- Feathered tread edges: May indicate alignment problems or related mechanical issues.

- Irregular wear across the tread: Can result from pressure differences, alignment issues, or suspension conditions.

These patterns do not establish a definitive diagnosis. A professional inspection can identify the underlying cause and help prevent premature wear on replacement tires.

<h3>Know When a Puncture Is Repairable</h3>

A small puncture in the central tread area may be repairable, depending on its size, location, and the tire’s overall condition. Damage in the shoulder or sidewall generally makes a tire unsuitable for repair.

A qualified technician should inspect the tire internally before determining whether a repair is appropriate. A standard permanent repair generally requires a suitable method that fills the puncture and seals the inner liner.

Large punctures, overlapping repair areas, or additional structural damage may require replacement. An external plug alone should not be assumed to provide a complete permanent repair.

<h3>Maintain Correct Tire Pressure</h3>

Correct inflation supports handling, braking performance, and even tread wear. Incorrect pressure can affect vehicle stability and shorten tire service life.

Check pressure when the tires are cold, ideally before driving or after the vehicle has been parked for several hours. Follow the recommended pressure on the vehicle’s tire-information label or in the owner’s manual, rather than the maximum pressure printed on the tire sidewall.

Check pressure at least monthly and before longer journeys. Inspect the spare tire according to the vehicle manufacturer’s recommendations.

<h3>Establish a Tire Inspection Routine</h3>

Regular inspections provide an opportunity to check tread depth, pressure, sidewalls, and overall tire condition. Address unusual wear, persistent vibration, or repeated pressure loss promptly.

Replace tires that reach the applicable tread limit or have damage or deterioration that makes continued use unsuitable. Bulges, exposed cords, and significant structural damage require prompt professional assessment. If a tire appears unsafe, avoid driving on it and arrange appropriate assistance.

<h3>Make Tire Care a Priority</h3>

Reliable tire performance begins with regular inspections and timely maintenance. Monitoring tread depth, maintaining correct inflation, recognizing structural damage, and following manufacturer recommendations help drivers make informed replacement decisions.

A consistent tire-care routine supports dependable handling and helps keep every journey safe and comfortable.
