When Do You Need New Tire Installation?

When Should I Replace My Tires?

Several warning signs can indicate degradation and the need for a new tire installation. These include excessive uneven wear, cracks, flat spots, embedded nails or stones, and less than 3mm tread depth.

Let's take an in-depth look at some of the most common symptoms that your tires are not in the best shape:

1. Tire Degradation

With constant exposure to heat, sunlight, moisture, and chemicals on the road, the rubber compounds in tires naturally undergo degradation and damage over time.

The condition and performance of all tires gradually deteriorate, even with minimal use. As tires age, their rubber loses its elasticity and grip, increasing the likelihood of tread separation and blowouts.

It is essential to regularly inspect tires for signs of degradation and replace them when necessary to ensure optimal performance and safety on the road.

2. Cracks & Cuts

Rough weather conditions, extreme temperatures, and particles on the road make the tires susceptible to erosion and cracking. These cracks and cuts weaken the tire’s structure, increasing the risk of failure.

Surface cracks on the sidewalls and at the base of the tread grooves may not always indicate severe tire damage. However, when these cracks penetrate deeper into the rubber, it becomes crucial to replace the tire.

Maintaining proper tire pressure is essential because underinflated and overinflated tires are more prone to developing cracks.

3. Bubbles & Blisters

Bubbles on a tire's surface typically occur due to an impact, such as hitting a pothole, curb, or other objects on the road. These bubbles, also known as bulges or blisters, appear when the tire's internal structure has been compromised and usually indicate severe tire damage.

Using a tire with a bubble increases the chances of a catastrophic tire failure, which can lead to loss of control and accidents. If you notice a bubble on your tire, it is best to have it inspected by a professional and replace it as soon as possible.

4. Embedded Nails or Stones

When a nail or stone gets lodged in the tire, it poses a potential risk. The embedded stone or nail can pierce through the tire’s tread and cause air leakage, gradually leading to a loss of tire pressure.

You should never ignore the hole or embedded object, even if there isn't a leak. Moisture can make its way into the tire and lead to rusting of its steel components.

If you notice an object stuck in the grooves of your tires, it is crucial to address the situation and remove it without delay. Taking swift action is essential in such cases.

5. Excessive Uneven Wear

When tires wear unevenly, the tread is worn down at different rates across the tire surface rather than wearing uniformly. This can compromise traction, handling, and braking efficiency, potentially reducing control and safety.

If you observe a vibration in the steering wheel while driving, this may indicate your tires being worn down unevenly.

Regular tire maintenance, including proper inflation, alignment checks, suspension inspections, and timely tire rotations, can help prevent and address excessive and uneven wear.

6. Flat Spots

Flat spots in tires can occur when a vehicle remains stationary for an extended time, especially in cold weather or on uneven surfaces. A worn section of the tire tread is a quick way to identify these flat spots.

Sometimes, the flat spot may not be visible but will cause a bumpy and uncomfortable ride. The flat spot can lead to severe tire damage or failure if left unattended.

7. Tread Depth Less Than 3mm or 4/32"

In many states, tires are considered worn down when the remaining tread depth is less than 3 mm or 4/32 of an inch. This means the tires have reached a level of wear that may compromise their performance and safety.

Causes of Tire Damage and Degradation

Several factors can cause tire damage and degradation over time. Here are some common causes:

1. Physical Trauma

Hitting potholes, curbs, or other road hazards can result in tire damage, including punctures, sidewall bulges, or impact breaks.

2. Under/Overinflation
3. Regular Wear
4. Cracks & Dry Rot
5. Uneven Tread Wear

Tire Life: Tread Depth

The tread is the part of the tire that comes in contact with the road surface. If the tread depth is insufficient, your car can lose traction, leading to longer braking times and reduced driving stability.

In the United States, tires are required to have a minimum tread depth of 2/32 of an inch. If the tread depth falls below this threshold or is approaching it, it is recommended to replace the tires.

Note that winter conditions can introduce additional road hazards, like salt, snow, and ice, which can impact tire grip. However, an increased tread depth can improve traction during winter and ensure your safety.

Most experts recommend a tread depth of 5/32 of an inch or more for winter driving.

Tire Age

As tires age, changes in their chemical composition gradually harden the rubber and reduce their flexibility and elasticity.

Old tire rubber may also have reduced shock-absorbing capabilities, which can result in a harsher and less comfortable ride for the occupants.

It is recommended to regularly inspect tires for signs of deterioration to minimize the impact of aging. Storing tires in a cool, dry environment away from direct sunlight can also help slow aging.

Recommended Tire Replacement Timeline

Tire wear is a natural consequence of driving. The duration for which tires remain in good condition depends on multiple factors, such as the miles driven and the road conditions.

If your daily commute involves unpaved roads, potholes, or other challenging conditions, it is advisable to have your tires regularly inspected. Adverse weather conditions like poor or extreme weather can also contribute to accelerated tire wear.

Additionally, aggressive driving behaviors, such as sudden acceleration, hard braking, and aggressive cornering, can increase tire stress, leading to a shorter lifespan. Drive responsibly and maintain your tires to ensure longevity.
