Tires are one of the most critical components of vehicle safety, yet they are often overlooked. Worn or damaged tires can lead to accidents, poor handling, and blowouts on the road. Proper maintenance and regular inspections are essential to keep your vehicle running safely. This article highlights 10 signs that your tires may need replacement and offers insights to help you identify when it’s time to visit your local tyre fitter.
1. Tires Are Too Old
Even if your tires have good tread, their age can affect performance. Most tire manufacturers recommend replacing tires after 5 to 7 years, with 10 years being the absolute maximum.
Tires naturally degrade over time due to exposure to the elements, leading to compromised safety.
To determine the age of your tires, check the DOT code stamped on the sidewall. The last four digits reveal the manufacturing date, with the first two indicating the week and the last two the year. For example, “1318” means the tire was made in the 13th week of 2018. Always ask your tyre fitter to inspect new tires for their manufacturing date to ensure you aren’t buying old stock.
2. Low or Bald Tread
Tires with little to no tread are dangerous, especially in wet conditions. Worn-out tires reduce grip and increase the likelihood of hydroplaning, making it difficult to maintain control of the vehicle. Most regulations require at least 2/32 inches of tread for a tire to be roadworthy. Regularly check tread depth and replace tires when they no longer meet the legal or safety requirements.
3. Exposed Belts or Cords
If belts or cords are visible on the surface of the tire, this is a serious issue that indicates severe wear. Misaligned wheels or failure to rotate tires often cause this uneven wear. Cords are typically exposed on the inside edge of the tire, making them easy to miss without a close inspection. A tyre fitter can help spot this problem before it leads to a dangerous blowout.
4. Overinflated Tires
Overinflated tires wear down the center tread faster than the edges because only the middle section makes full contact with the road. This reduces grip and affects handling. Overinflation can also increase the risk of a tire bursting. It’s essential to monitor tire pressure regularly, especially as temperatures change, and keep it within the recommended range.
5. Underinflated Tires
Underinflated tires show the opposite pattern, with the outer edges wearing down faster than the center. Underinflation reduces fuel efficiency and causes the tires to heat up excessively, which can lead to tire failure. Regularly check your tires with a pressure gauge and adjust as needed. If you notice uneven wear, have a tyre fitter inspect your tires and check for potential leaks.
6. Cupping or Flat Spots
Cupping occurs when sections of the tire tread wear unevenly, creating high and low points. This can result from poor suspension, unbalanced tires, or failing to rotate them on schedule. You can feel cupping by running your hand along the tire surface or notice it as a thumping noise when driving.
Flat spots, on the other hand, occur when a tire sits in one position for too long, usually on vehicles like trailers or RVs. The affected tire will vibrate noticeably at higher speeds. Some flat spots may smooth out with use, but others will require replacement.
7. Tire Bulges
A bulge on the tread or sidewall is a warning sign of internal damage. Bulges form when the tire structure is compromised, often due to hitting a curb or pothole, causing the internal cords to break. This creates a weak spot, which could result in a blowout if not addressed promptly. If you notice a bulge, take your vehicle off the road immediately and have a tyre fitter replace the damaged tire.
8. Cracked or Dry-Rotted Tires
Tires exposed to extreme weather conditions–such as intense sun, rain, or freezing temperatures–can develop cracks. Chemicals used on roads in winter also accelerate cracking. Once cracks appear, moisture can seep into the tire and corrode the internal steel belts, leading to separation between the tread and the rest of the tire. Even if the tread looks sufficient, a cracked tire can fail unexpectedly and should be replaced.
9. Too Many Repairs or Patches
While some minor punctures can be repaired, there is a limit to how many times a tire can be safely patched. Most tire manufacturers recommend no more than two repairs, and only if the punctures are in separate locations. Patches near the sidewall are generally unsafe, as this area endures significant stress. If your tires have been repaired multiple times, it’s best to replace them for peace of mind.
10. Cuts or Chunking
Cuts on the sidewall or tread should never be ignored. Even small cuts can worsen over time, weakening the tire and increasing the risk of failure. Chunking, where pieces of tread are missing or torn away, is often caused by driving on poorly maintained roads. If you notice cuts or chunks in your tires, have them inspected by a tyre fitter to determine if they are still safe to use.
Conclusion
Your tires play a crucial role in keeping your vehicle safe and performing well on the road. Regular inspections, proper inflation, and timely replacements are essential to prevent accidents and ensure smooth driving. If you notice any of the issues outlined above, don’t delay–schedule an appointment with a tyre fitter to assess your tires and make the necessary replacements. Investing in new tires when needed can save you from costly repairs, breakdowns, or dangerous situations down the road.
