If you notice excessive wear on the inside or outside edges of your tires, it may be a sign of an underlying issue that needs to be addressed. Regular tire rotation and alignment checks can help prevent this type of tread wear and prolong the lifespan of your tires.

Tread Depth

Tire Tread Wear Indicator Bars

Tire tread wear indicator bars are small rubber bars that appear within the tread grooves of your tires. These bars serve as a visual indication of the remaining tread depth. As the tread wears down, these bars become more visible. When the bars are flush with the rest of the tread, it indicates that the tire has reached the minimum legal tread depth and needs to be replaced. Regularly checking the tread wear indicator bars can help you determine when it’s time to invest in new tires for optimal safety on the road.

Tire Tread Depth Gauge

Using a tire tread depth gauge is another effective method for checking the tread depth of your tires. This handheld tool allows you to measure the depth of the tire grooves accurately. The recommended minimum tread depth is typically around 4/32 of an inch or more depending on your local regulations and driving conditions. If the tread depth falls below this threshold, it’s a clear sign that your tires are worn and may no longer provide adequate traction and grip on the road.

Sidewall Damage


Inspecting your tire sidewalls regularly is essential to identify any signs of damage. Cracks on the sidewalls can indicate age, weathering, or potentially more severe issues. These cracks can be caused by exposure to harsh elements, extreme temperatures, or simply the natural aging process. While small cracks may not pose an immediate threat, larger or deep cracks can weaken the sidewall structure, compromising the overall integrity of the tire. If you notice sidewall cracks, it’s highly recommended to consult with a tire professional to determine the appropriate course of action.


Bulges or bubbles on the tire sidewall can be a significant cause for concern. These bulges are often a result of internal damage, such as a broken belt or ply separation. When a tire develops a bulge, it becomes more susceptible to blowouts, particularly at high speeds. If you notice any bulges or bubbles on your tire sidewalls, it’s crucial to replace the affected tire immediately to avoid potential accidents and ensure your safety on the road.

Punctures are another form of sidewall damage that can occur as a result of road debris, nails, or sharp objects. It’s important to keep an eye out for any visible punctures on the sidewalls of your tires, as they can lead to air leakage and potential tire failure. If you identify a puncture, it’s recommended to have it inspected and repaired by a professional. In some cases, depending on the severity and location of the puncture, tire replacement may be necessary.

Tire Age

Tire Manufacturing Date Code

Determining the age of your tires is crucial, as tires can degrade over time even if they have sufficient tread depth. The tire manufacturing date code can be found on the sidewall of your tires and is typically a four-digit number. The first two digits represent the week, and the last two digits indicate the year of manufacture. As a general guideline, it is recommended to replace tires that are six years or older, regardless of their visual condition.

Roaring or Vibrating Noise

Another sign of tire age is the development of unusual noises while driving. Over time, tires can develop irregular wear patterns, which may result in increased road noise or vibrations. If you start noticing a persistent roaring sound or vibrations, it may be an indication that your tires are nearing the end of their lifespan. Having your tires inspected by a professional can help identify any underlying issues and determine if tire replacement is necessary.

Excessive Vibration

Wheel Alignment

Improper wheel alignment can lead to excessive vibration, which can be felt throughout the vehicle while driving. If your wheels are not aligned correctly, it causes the tires to wear unevenly, resulting in an imbalance and vibrations. It’s important to have your wheel alignment checked regularly to ensure that your tires wear evenly and to maintain a smooth, comfortable ride. If you notice vibrations or uneven tire wear, it’s recommended to have your alignment adjusted by a professional.

Wheel Balance

Wheel balance is another crucial factor that affects the overall smoothness of your ride. When the wheels are out of balance, it can cause vibrations at higher speeds, leading to discomfort and potential handling issues. Poor wheel balance can be rectified by having the tires and wheels balanced by a professional. Properly balanced wheels contribute to better tire longevity and overall driving experience.

Worn or Damaged Valve Stems

Valve stems are the small rubber components that allow for the inflation and deflation of your tires. Over time, valve stems can deteriorate and become worn or damaged, leading to air leakage. If you notice slow loss of tire pressure or visible damage to the valve stems, it’s important to have them replaced immediately. Neglecting valve stem maintenance can result in poor tire pressure retention and potential tire failure.

Dry Rot

Deep Cracks

Dry rot refers to the cracking and splitting of the tire rubber due to prolonged exposure to UV rays, heat, and ozone. Deep cracks can form on the tire sidewalls and tread, compromising the structural integrity of the tire. Dry rot can be identified by the presence of extensive cracking that is beyond the surface level. If you observe deep cracks on your tires, it’s essential to have them inspected by a professional, as dry rot can lead to unexpected tire failure.

Brittle or Hard Rubber

Another sign of dry rot is the brittleness or hardness of the tire rubber. As tires age and experience prolonged exposure to harsh elements, they can lose their flexibility and become brittle. Brittle rubber is prone to cracks and damage, making the tire more susceptible to punctures and blowouts. To prevent the risks associated with dry rot, it’s recommended to regularly inspect your tires for signs of brittleness and replace them when necessary.

Poor Handling or Increased Braking Distance

If you notice a change in the way your vehicle handles or experience an increased braking distance, it may be a sign of tire wear and tear.
