At Goodyear, we clearly recognize the importance of tires for safe driving. For this reason, we will explain below how to properly maintain tires. Through this article you will get your tires to the best performance and achieve safe driving.
Before replacing the tires, first consult the vehicle manual and follow the tire replacement recommendations provided by the vehicle manufacturer. The way the vehicle is handled may be significantly affected by changes in the size and type of the tire. When selecting a tire that is different from the original tire size, consult a professional installer to select the proper clearance, load, and inflation pressure. Never exceed the maximum load weight and inflation pressure listed on the side of the tire. Always drive safely and follow all traffic regulations. Avoid sudden, sharp turns or lines. Failure to comply with this warning may result in the loss of control of the vehicle and cause traffic accidents and severe personal injury or death.
The correct tire pressure
Maintaining the correct air pressure is the most important thing the driver can do for the tire. About every other month, the tire will lose 4.5Kb/cm2 pressure. It is very important to check the air pressure regularly to ensure that the tire will never overpressure or underpressure.
Underpressure is the biggest enemy of the tire. It will increase the wear of the tread pattern at the outer edge (or shoulder) of the tire. It also generates excessive heat and reduces the life of the tire. Lastly, it will also increase fuel consumption due to increased rolling resistance. The softening of tires makes it harder for the vehicle to travel.
Overpressure is also harmful to the tires. Too much pressure will cause the center of the tread to bear most of the weight of the vehicle, causing the tire to age and wear unevenly. Any uneven wear will shorten the life of the tire.
To ensure the correct air pressure for your tires, consult your vehicle's instruction manual or look inside the driver's side doorpost or glove box. If you are buying a new tire, be sure to ask the retail store for the correct value. Check the air pressure at least every other month and use an accurate tire pressure gauge. Alternatively, you can also drive your car to a Goodyear authorized retail store where they can check for pressure and correct it for you.
Balance and adjustment
It is important to keep the tires in balance and correct them properly. This will not only extend the life of the tires, but also help ensure the safety of the driver and give full play to the car's performance.
Unbalanced tires will vibrate when they are on the road, making the driver more prone to fatigue, increasing tire wear (also known as cup wear or pit-like wear) and causing unnecessary wear on the vehicle's suspension system. Tires should be balanced before they are installed for the first time or reinstalled on the wheel after repair. The tires should also be re-balanced after any signs of vibration or oscillation have been found, and in addition, the tires should be balanced once a year, irrespective of whether there is such an indication.
If all the suspensions and steering components are working properly, or if the tires and wheels are assembled together and remain straight forward, then the vehicle is well tuned. Proper alignment is essential to achieving uniform wear and precise steering of the tread. If the front and rear tires wear unevenly, or the vehicle's steering or steering behavior changes, then the vehicle is not adjusted.
The money spent on tire balance and vehicle alignment will be rewarded with longer tire life, better performance and better comfort. Your local Goodyear authorized retail store will be happy to book a balance and correct service for you.
Regular rotation
The weight of the car was not evenly distributed to all four tires. Therefore, regular rotation is indispensable for maintaining uniform wear of the tire and maximizing tire life.
There are several ways to rotate tires. For all-season tires and most vehicles traveling on standard roads, the tires on the rear axle and the tires on the front axle can be exchanged and replaced diagonally. However, when changing the tire on the drive shaft to the rear axle, it should be exchanged with the same side tire. This is called the "modified X" mode.
Tires with directional design (such as Goodyear's new Eagle high-performance tires) should adopt different rotations. In this case, all tires should be exchanged before and after the same side of the tire.
For four-wheel drive vehicles, it is recommended that all four tires be exchanged, ie, the front and rear axle tires adopt a diagonal exchange method.
Please also consult the user manual for the manufacturer's rotation advice. If no rotation period is specified, it should be adjusted every 9654-12872 kilometers. Four-wheel drive vehicles may need to be rotated every 6,436 kilometers. The first rotation of the tires is very important. Please do not forget to adjust the inflation pressure after each rotation according to the recommendations of the vehicle manufacturer. Your local Goodyear authorized retail store can arrange rotation services for your vehicle at any time.
Visual inspection
In general, visual inspections can be used to identify potential problems with the tire. When checking the air pressure next time, check if there is a sharp object on the tread that may scratch the tire. Even if the mouth is not deep and the tires are not immediately leaked, the cracks and dents caused by the small cracks will eventually get worse and cause problems when the car is driving.
Also check the way the tread wears. Excessive shoulder wear indicates insufficient inflation of the tire, while wear at the center indicates tire overpressure.
Many tires have some tread wear indicator blocks in the tread. If the wear depth of the tread has reached the height of these rubber blocks within the width of the tread, it means that the tire should be replaced.
When you find that there may be a problem or feel that you should change a new tire, please drive the vehicle to the nearest Goodyear authorized retail store for repair.
repair
It is important to understand whether tires should be repaired or replaced. If the tire leaks, it must be removed from the vehicle and a thorough internal inspection must be performed to ensure that it is not damaged. Even tires that can leak when traveling a very short distance are often tires that have been damaged and cannot be repaired.
Most scratches, nails, or cuts within 0.64 cm can be repaired by a trained technical worker as long as the damage occurs only on the tread. If the crack is longer than 0.64 cm or occurs on the side of the tire, the tire should not be repaired. In addition, tires with tread pattern depths worn to less than 0.16 cm should not be repaired.
Skilled professionals can handle most tire repairs. Rapid repair of flat tires can help you reach a safe location. However, the safest way is to prepare a spare tire in the trunk. Make sure the spare tire is inflated to the correct air pressure and it looks good.
In the event of any problems with the tires, the car should be immediately opened to the nearest authorized retail store in Goodyear, and has received high-quality professional services.
