6 Steps to Self-Check Tires After Commercial Vehicle Modification

As the "feet" of the car, the tires always serve the car owners silently. In fact, no matter how fast the car runs, it is impossible to leave these four feet. However, such a critical part is likely to be overlooked. Today, commercial vehicle modification experts will teach you several ways to self-check tires.

Punch

Has your car been punctured? If so, how long ago was it? In fact, for tires that have been repaired for a long time, even if they can be used temporarily, the load-bearing capacity under extreme loads will be much greater than before; in addition, if the same tire has more than 3 holes, we recommend that you replace it as soon as possible.

Swelling

If the car passes through pits, obstacles, and curbs at high speed, the tires will be severely deformed under the local huge impact force, and the internal pressure will increase instantly. The direct consequence is that the tire cord will break and cause bulges. In addition, under the same impact force, low-profile tires are more likely to cause sidewall bulges than high-profile tires. Tires that have been bulged must be replaced immediately, otherwise there will be a risk of tire blowout.
Tread

Generally speaking, the tires of household cars in normal use can be replaced every 60,000 kilometers or two years, but tires with severe tread wear should be replaced earlier. Now all fast repair shops have fixed wear scales. Car owners can buy at any time to check the wear of the tire pattern. In addition, the increase of tread cracks is also a sign of serious aging. You can spray some tire protection wax appropriately at ordinary times, and try not to press corrosive liquids when driving.

Pressure

Now most household cars use tubeless radial tires. For front-wheel drive cars, because important driving components such as the engine and gearbox are pressed in front, the front wheels sometimes look a little flat, but visual inspection is not accurate. Be sure to use a special tire pressure gauge to measure. Generally speaking, the front wheel pressure is between 2.0 Pa and 2.2 Pa (due to the different uses and designs of each car, it is recommended to refer to the manufacturer's values ​​calibrated in the user manual), which can be lower in summer.

Gravel

Some car owners often hear their cars make a "bang" sound when driving, but the car does not break down when in use. At this time, check whether there are small stones stuck in the tire pattern. In fact, as long as you use a key to dig out these small stones in the tread pattern, it will not only make the tire's braking grip more stable, but also avoid tire noise.

Spare Tire

If you want the spare tire to play a real emergency role, you should pay attention to its maintenance. First, check the spare tire pressure frequently; second, the spare tire should be protected against oil corrosion. The spare tire is a rubber product and is most afraid of erosion by various oils. When the tire is stained with oil, it will soon swell and corrode, which will greatly reduce the service life of the spare tire. Finally, the service life of the spare tire is about 4 years. Many car owners mistakenly believe that the spare tire is always new when it is not used. In fact, after 4 years, the spare tire must be replaced even if it has not been used once, otherwise the spare tire will become a waste tire.
