Vehicle tires play a significant role in safety. They are the main factor that affects the handling, braking, and driving safety of a car.

Signs of tire wear

Minor troubles are the first sign that it’s time to pay attention to tires

Make it a rule to carry out visual inspections of tires regularly.

If you notice any signs of initial wear, check, and correct the following problems or replace the tires:

  • Cracks or cuts on the sidewalls of the tires.
  • The tread does not wear evenly. The reasons can be different: uneven tire pressure, imbalance, tire damage or problems with some suspension parts.
  • Excessive tread wear. Most modern tires have tread wear bars, which indicate a minimum tread depth of 1.58mm. When the tread wears down to this mark, then it’s time to change the rubber. Inexpensive tread-wear checkers are available from auto parts stores or specialist rubber outlets.
  • Alternatively, you can use a Lincoln head coin to measure the tread size. Insert it into the groove of the tread, with the president’s head to the tire. If you can see the top of Abe’s head, then the protector is worn out.
  • Bulges or bulges. If you find such damage on the sidewalls of the tires, replace them immediately. They indicate that the rubber has worn out to the extreme in these places and can burst at any time.
  • Excessive vibration. Tire vibration can mean a wheel is loose, out of balance, or bent. It could also be a sign of internal tire damage. Don’t ignore the vibration: drive your car to a car service immediately.

Insufficient tire pressure problem

The checks carried out showed that at least half of the cars on the highway could ride on one or two insufficiently inflated wheels. Part of the problem is that some of the air from the tires escapes through the rubber, which interacts with the wheel and valve. And sometimes, it happens so slowly that most drivers do not understand how this happens.

In addition, seasonal fluctuations in air temperature can also lower tire pressure.

Since the sidewall deflects more at low pressure, this is fraught with loss of control over the car’s handling, which is the main task of tires. Even a slight decrease in pressure, such as 0.28 kg-s / cm², can significantly complicate the vehicle’s handling. In addition to this, insufficient pressure in the wheels leads to excessive consumption of fuel, which will cost you a pretty penny.

Excessive bending of the tire sidewalls can cause the tire to overheat. And this, in turn, will significantly shorten the life of the rubber and can also cause the tread to flake or rupture.

Tips for rubber care

  • Never measure tire pressure by eye. Modern radial tires always appear to be slightly concave from the side, so they may appear to be under-inflated, although they are not.
  • See to it that your vehicle is equipped with the corresponding tires. Do not buy cheap or used tires. Do your research on the best car tires in UAE.
  • Check the pressure in all four wheels and the spare tire using a particular sensor at least once a month. You can buy it at any auto parts store.
  • Inflate your tires strictly to the rate set by the car manufacturer. Its value is indicated on a plate in the passenger compartment, on the door pillar, fuel tank cap, or inside the glove compartment lid. Never inflate to the “maximum pressure” printed on the tire. The same goes for the spare wheel. If your car, has it, it should be inflated to about 4.22 kg-s / cm².
  • Measure the pressure on cold tires until the vehicle has driven two to three kilometers. As soon as the car starts to move, the rubber heats up, and the pressure inside rises, making it impossible to determine its fundamental level.
