Can You Patch The Sidewall Of A Tire?

The most common reason for a tire to need a patch is due to punctures caused by nails, screws, or other sharp objects lying on the road. The tire should be replaced immediately if a puncture occurs within 2 inches of the sidewall.

This is because punches that occur on the sidewalls of a tire do not withstand patches for a long time. Moreover, if the tire is damaged or punctured up to the sidewalls or shoulder, then it means that the damage is severe, and can affect the overall structure of the tire.

Even minor scratches on the skin of the sidewall are unimaginably dangerous. As the sidewalls of a tire continue to deteriorate over time, the tire becomes more susceptible to blowouts.

Tire Sidewall Damage Causes And Solution

Several factors are responsible for causing damage to the side walls of a tier. Below, I have listed some of the most important factors –

Causes and solution

Wear And Tear

Excessive and aggressive usage of the same tire for a long time can cause changes in the entire structure of the tire. The heavy wearing and tearing of the tire can cause it to dry out and develop cracks on the sidewall. These cracks are mild in the beginning, but they spread out quickly, making the tire weak and hazardous.

To avoid cracks and premature wear and tear, it is best to store tires properly, avoid diving aggressively and maintain the recommended PSI.

Overload

Overloading the vehicle more than its capacity can put more stress and strain on the shoulder of the tire, causing it to reduce its lifespan and build up more heat on the tires.

To ensure that you do not overload the vehicle, experts recommend referring to the owner’s manual and loading the vehicle according to the specified limit

Improper Air Pressure

When the tires of the vehicle are either under inflated or overinflated, it can lead to a change in the structure of the tire and cause damage, tears, holes, or cracks on the sidewall of the tire. So it’s important to inflate your tire to the recommended pressure level.  

High Exposure To Chemicals And Sunlight

Extreme exposure to sunlight and chemicals on the tire’s surface can cause it to melt or change its chemical configuration, which might lead to sagging of the tires. Riding on sagged tires can cause the tire sidewall to reduce stability and increase the risk of puncture and blowouts.

To avoid extreme Exposure to sunlight and chemicals, it is advisable to park the vehicle in the shade and use tire covers while cleaning them regularly. Experts also suggest rotating tires every 5,000 to 7,500 miles to ensure their safety and durability.

Why Can’t A Tire Sidewall Be Patched?

The reason why a tire cannot be patched in its sidewall is that it deteriorates the tire’s longevity and weakens it over time

A tire’s tread contains a network of cords, which remains sturdy when coming into contact with the road’s surface. But these chords are not present around the side wall area of the tire.

If a puncture or damage is repaired around the sidewalls or shoulder of a tire, it is more likely to experience intense damage due to excess pressure. This could lead to potential repair failure.

Damaged sidewall tire of a car

Once there is damage caused in the sidewalls of a tire, immediate replacement to atleast a donut tire is needed because it compromises the integrity of the tire and the vehicle’s safety. It is not safe to drive a tire that is abraded even lightly. Damages caused on tires anywhere apart from the shoulder and sidewalls can be repaired.

How Thick Are Tire Sidewalls?

Usually, there is a variation in the thickness of the tire sidewall ranging from the area between the shoulder and the beads.

The thickness of the tire’s sidewall varies based on the brand, quality, and intent of the use. Generally, tire manufacturers manufacture most tire sidewalls with a thickness of 6 to 15 mm, which is about 1/4 to 5/8 inches.

Regularly checking tire pressure is important to ensure that the tire maintains the recommended PSI in order to keep the patches intact. In case of a puncture, external patching of the tire is highly inadvisable, and immediate replacement of the tire is mandatory.

What Causes Hole In Tire Sidewall?

Sidewall is a sensitive part of the tire. When a tire is underinflated, it damages the sidewall first. An under-inflated tire stretches more in the side wall causing it to reshape and sag due to heating while driving at high speed.

In extreme climates, driving aggressively on a hot surface can worsen the condition of the sidewalls, but taking preventive measures beforehand can help maintain them.

In some cases, holes on sidewalls do not occur immediately. They might have first occurred in the tread of the tire, which slowly spreads on the side walls causing damage to the area. These tires are highly dangerous and are most likely to burst under pressure. Even a minute scratch seen in the sidewalls of a tire is dangerous, and you should replace it immediately for safety concerns.

Should You Replace A Tire With Sidewall Damage?

Definitely yes. You should not take any damage to the sidewall lightly. It is more dangerous than the damages caused in any other part of the tire. Whether it is a bulge, scratch, crack, or hole in the tire’s sidewall, immediate changing of the tire is essential for ensuring safe driving.

Why Can’t You Patch A Tire Shoulder?

A tire’s shoulder is as sensitive as the side walls. They might need high supervision and immediate replacement when damaged like the sidewalls because shoulder injuries in tires are equally serious as sidewall injuries.

So patching up tires in their center and tread area is acceptable, but not anywhere in the shoulder or side walls of the tire. They are unrepairable.

Tire Sidewall FAQ

Avoid patching your tires too close to each other because, in most cases, the tire weakens when there is more than one puncture patch. If your tire has more than one puncture patch, experts recommend replacing it with a new one. However, in case of emergency, you can use a tire that has patches not less than 2 to 3 inches apart.

It is necessary that you follow the instructions given by your tire manufacturer to know the speed limit of your patched tire, as the speed limit depends on the severity of tire damage. In most cases, experts do not recommend driving tires with excessive patches beyond 50 MPH.

The location, size of the puncture, and type of patch used determine the longevity of a tire patch.

So basically, the more patches your tire has, the weaker the tire gets. Some manufacturers advise that a tire should not have patches close to 2 or 3.

Unless the patch is on the side walls or shoulder area of the tire, it is safe to use.
