When to change car tires

The tires are the pillars of the car and should be checked on a monthly basis, the aspects that should be taken into account are the following: depth, tread condition, sidewall damage, pressure and any signs of wear in general that can be observed. If you have any doubts about the condition of your tires, do not hesitate to consult a specialist who will tell you whether or not they are fit for driving.

It is essential to dismount the tire to be able to check if there is any damage and what is the importance of it. Without further ado, the main reasons are:

1. To change in case of a puncture.

The resistance of tires today has improved exponentially, withstanding almost everything. However, punctures are always inevitable. In case of a flat tire, take it to a specialist who will check it and detect possible hidden damage to the tire.

2. Know when they reach the limit of wear.

It is convenient to check the wear of each tire regularly, but not everyone knows how to do this.

Some tires have a logo or a marked dummy made of the same material, which is used to locate the wear of the tires. For example, Michelin tires have the logo of the brand, when the height of the wear reaches this it is necessary to replace the tire.

It is important to pay attention to the relief of the tire, when it reaches 1.6mm it is no longer considered safe. The elevations formed in the relief should be evaluated according to the wear, when the elevations are aligned with the relief it is time to change it.

3. Signs of aging.

The aging of tires is something predictable, regardless of the time of manufacture, there are many circumstances that affect the life of the tire, such as maintenance, storage, temperature, speed, the use given to it, the driving style, etc..

To know the aging of the tire, it is necessary to pay attention to the grip, once it has aged too much it can lead to loss of grip. If you consider that the tire is still in good condition due to little use, but it is too old, you can perform the five-year test.

This test consists of an annual inspection (at least) to determine the age of the tire. Some brands recommend not to use the same tires for more than 10 years, even if they have not reached their legal limit of wear.

4. Damage to the tires.

When colliding with a single object, the wheels can be severely damaged. Inspection by a professional will be necessary to identify any possible cuts, deformations or punctures. All this is focused on safety, so that it is possible to rule out any damage and know whether the tire can be repaired or needs replacement.

Verify that there are no protuberances in the tread.

When a bulge is observed on the sidewall of the tire, it is a sign that the internal structure has been damaged. This damage could have been caused by driving over a curb, or a large pothole. Continued use of tires with this internal damage can be dangerous because the tire structure has been significantly reduced, increasing the likelihood of tire failure, punctures, or other causes of accidents.

Some situations in which it should not be repaired are:

  • Rubbers that have come unstuck.
  • Plains with creases.
  • Deterioration due to corrosive products.
  • Noticeable deformity to the eye.
  • Deterioration due to corrosive products.

5. Abnormal tire wear

Abnormal and irregular wear usually indicates a mechanical problem with the vehicle, such as improper alignment or a suspension, transmission or balancing problem. Sometimes it can also be caused by inadequate tire pressure.

To avoid this type of wear it is necessary to perform a periodic inspection of the car’s steering, damping, change of tire position, brakes, etc. When new tires are mounted, they should be balanced and the steering corrected in case of defect. This will extend the life of the tires.

Depth test indicator: can be used as a tool for relief test. It is very economical and easy to use.

6. Do not use unsuitable tires for the vehicle.

If good results are to be obtained it is necessary to use the same type of tire on each wheel, different sizes or shapes affect the stability, mechanics and handling of the vehicle.

Mixing diagonal tires with radials on a vehicle is not recommended. In case of making this assembly it will be necessary to mount the radial tires on the rear axle and the diagonal tires on the front axle.

If you are not sure which tire is best suited to your vehicle, there are many ways to find them, visit a dealer who can advise you according to the brand of the tire.

7. Check for bulges in the tread.

When you see a bulge in the sidewall of the tire, it is a sign that the internal structure has been damaged. This damage could have been caused by driving over a curb, or a large pothole. Continued use of tires with this internal damage can be dangerous as the tire structure has been significantly reduced, increasing the likelihood of tire failure, puncture, or other causes of accidents.

8. Pay attention to vibrations in the steering wheel.

Uneven tire wear often causes vibration in the steering wheel when driving. If this is the case, the tires will need to be rebalanced to eliminate the vibration.

These vibrations are sometimes caused by cupped tires, which indicate uneven wear when they have not been rotated correctly and regularly.

These are some of the most common indications of when a tire needs to be replaced. As a final recommendation, always be attentive and in the event of any irregularity, opt to replace the tire – safety is paramount!
