However, we shall look at some common serious sidewall damage to look out for and be wary of. When your tire sidewall has its cords hanging outside, you have a serious issue on your hands.

Similarly, sidewall damage is very serious when you can see bubbles in or anywhere around your tire. As said earlier, any sidewall tire damage must be considered too much, since it can aggravate and lead to much bigger issues. (Read Also: Can I Use Tire Foam To Clean Engine?)

What Causes Tire Sidewall Damage?

Several factors are complicit in causing tire sidewall damage such as:

1. Under-Inflation

This can be traceable to the driver’s negligence. This is because tires are known to self deflate at a steady rate naturally and hence we should ensure to keep the pressure at normal levels by gauging the tire regularly. Where this function is willfully neglected, we can’t but see that as negligence.

2. Age Of The Tires

Under ideal circumstances, tires are adjudged as safe between the ages of eight to ten years. After this time, the strength, plasticity, and everything about the tire is much reduced, if not totally lost. At this stage, tire sidewall damage has a huge likelihood of occurring.

3. Damage

Tire sidewall damage can occur due to various road hazards or even very poor maintenance and installation. Damaged tires are bound to lose air rapidly and progressively degrade which may cause sidewall damage too.

4. Overloading

When you carry so much load that is beyond the designated capacity of the vehicle, you are in essence risking possible tire sidewall damage in your tire.

The theory is that an overloaded vehicle may veer out of control and wobble on the road from one side to another, which is a potentially very risky situation. As the vehicle wobbles on the road, tire sidewall damage may not be far behind.

5. Manufacturing Defects

When a tire is mistakenly rated for speeds beyond its capacity by the manufacturers, sidewall damage is very likely to occur in this instance.

Therefore, it is important to test tires adequately and ensure their proper speed rating before releasing them to the general public for consumption. Such poorly rated tires have the propensity to become overheated after installation.

6. Tire Wear

Worn tires are more likely to overheat faster than normal ones. Their cords may fall apart and begin to show and should you hit something like a curb in this condition, tire sidewall damage may be unavoidable.

Can Tire Sidewall Damage Be Repaired?

Yes, for the sake of discussion, they can be, but such repairs are for all intents and purposes useless. This is because you are not advised, for your own sake and maybe others as well, to drive a car with tire sidewall damage.

These so-called sidewall repairs, to start with, do not last and they also compromise the integrity of your tire. Even after you manage to place a patch on the tire sidewall, the patch would not stay in place because the rigors and stress suffered by a tire sidewall are too much for any patch to withstand. Essentially, therefore, sidewall tire damage cannot be repaired, in the strictest sense of the word.

Why Can’t I Repair Tire Sidewall Damage?

Tire Sidewall Damage

Tires with sidewall damage cannot be repaired because any patch on the sidewall would not hold.

This is because tires have cords all around their treads which allow any patch to stay in place, but on the sidewall, these cords are absent and this makes it impossible for the patch to stay in a hole.

Secondly, even with a patch in place, once a tire is injured on the sidewall, its integrity is compromised.

This means that it cannot perform at its best and is also not safe to drive on anymore. Even when used at slow speeds, the chances of a blowout are enormous.

Your best bet, when there is tire sidewall damage, is to replace the tire at once.(Read Also: How Close To the Sidewall Can A Tire Be Patched?)

Is It Safe To Drive On A Tire With Sidewall Damage?

It is never safe to drive on a tire with sidewall damage and that is because as you drive, the puncture, hole, or injury to the sidewall of the tire becomes bigger and worse, thereby putting yourself and other road users at risk due to possible sudden tire blowouts.

Secondly, as a driver moves on a tire with sidewall damage, the control of the vehicle is compromised and this implies that you risk the car venturing off the road leading to an avoidable accident.

Considering the fact that the sidewall of the tire, unlike all other of its parts, has no cords in it that hold the rubber together, it is regarded as the most vulnerable part of any tire, whose role in driving safely must not be taken for granted.

How To Read A Tire Sidewall

The sidewall of a tire bears numbers and letters which to the casual observer may mean nothing, but these numbers and letters, in reality, tell you a lot about the tire, including very important specifications and other details.

In fact, knowing how to read and correctly interpreted the message on the tire sidewall can effectively enable you to make correct choices when buying a tire.

For instance, let us look at a tire with the inscription ‘P225/50/R27 98H‘ on it. To start with, the P in the inscription stands for PMetric which identifies your tire as a passenger tire.

Where the inscription starts with LT rather than P, the tire is identified as a Light Truck Type, which means that you cannot use it for heavier vehicles.

The numbers ‘225’ tell you about the tire section width, which is the distance between the two sidewalls in millimetres. This measurement depends on the size of the rim.

The number ‘50‘ compares two things, which are the tire’s section height with the section width of the tire. In this case, it interprets that the section height of the tire is fifty per cent of its section width.

The ‘R’ stands for the construction utilized in its casing, which means Radial Construction. Instead of ‘R’, some tires may have ‘B’ or ‘D’ instead. B stands for Belted Bias Construction while a ‘D’ stands for Diagonal Bias Construction. The last number ‘17′ shows the diameter of the wheel rim which is mostly measured in inches.

The last numbers tell you the load index, speed rating, or service description of the tire. After this explanation, I am certain that now you know the numbers on the sidewall are not just some random verbose numbers, but very detailed information about the tire. Wow, this is gross, right?

What Causes Uneven Wear In Tires?

Tires may wear unevenly which many drivers hardly notice because they are basically concerned with when the tire treads are totally worn out.
