Tire maintenance and safety

In order to ensure the mileage and performance of the tires, it is recommended to conduct a simple inspection once a month to see whether the tire pressure is normal, whether the tires are worn evenly, and whether they are damaged.

Maintain proper tire pressure

Proper tire pressure helps you get good tire performance and fuel efficiency. Remember to use an appropriate tire pressure gauge (under cold tire conditions) to check the tires frequently (at least once a month).

Keep tire pressure to the recommended level

The vehicle's nameplate or owner's manual provides recommended tire pressure levels. Maintaining proper tire pressure is an important method to extend tire life and durability.
Insufficient tire pressure is the main cause of tire failure and may cause severe tire rupture, component detachment, or flat tires. Insufficient tire pressure will reduce the load capacity of the tire, cause excessive bending of the side walls, increase rolling resistance, and cause heat generation or mechanical damage.
Excessive tire pressure will increase tire hardness, cause uncomfortable driving, and cause unnecessary vibration. High tire pressure also increases the chance of impact damage.

Wheel speed must not be too fast

When the vehicle is stuck in snow, mud or sand, avoid turning the wheels too fast. This can cause a sudden tire puncture, causing damage to the vehicle and/or serious personal injury to you and the people around you. Gently swing back and forth to get the vehicle out of trouble. Do not stand near or behind the tires rotating at high speed, for example when trying to push the vehicle out of a dilemma, or when using on-board rotating balancing equipment.

Check tire wear

When the tread depth reaches 2/32 inch (0.16 cm), be sure to remove the tire. All new tires have a tread pattern indicator strip. When worn to the above level, the smooth surface in the tread groove will expose the indicator strip. Most accidents in wet weather are caused by bare or near bareness. Excessive wear is more likely to cause tire wear.

Check if the tire is damaged

Regular (at least once a month) inspection of the tires for signs of damage and overall condition is very important for tire safety. If in doubt, let the tire dealer check it for you. Damaged impacts, wear and tear, cracks, bumps, bulges, or leaks all require the tire to be removed for professional inspection. No temporary repairs, or replacement of inner tubes for correct repairs.

Correct tire repair

Note: Goodyear does not guarantee the inspection or repair process. Repairs are entirely the responsibility of the repair service provider and should be performed in accordance with established procedures of the Rubber Manufacturers Association.

Tire pressure monitoring system alarm

To learn more about the measures that should be taken when the tire pressure alarm system is activated, please refer to the owner's manual.

Do not attempt to install the tires yourself

Due to improper installation steps, the tire/rim assembly may burst, causing serious personal injury. Remember to follow the tire manufacturer's instructions or match the tire diameter to the rim diameter. Only professionally trained personnel can install the tires.

Do not install tires of different specifications and sizes on the same shaft

In order to obtain good handling, Goodyear recommends the installation of tires of the same type and size, unless specifically stated by the vehicle manufacturer.

caveat

Before changing tires, be sure to refer to the owner's manual and follow the vehicle manufacturer's recommendations for tire replacement. Replacing tires with different sizes or types will seriously affect the operability of the vehicle. When choosing other tires that are different from the supporting tires, please consult the professional installers to ensure that the appropriate installation spacing, load capacity and inflation pressure are selected. Do not exceed the load capacity and inflation pressure marked on the tire sidewall. When changing tires, you must use tires with the same outer diameter and load capacity as the matching tires. The inflation pressure needs to be adjusted to avoid tire overload. For correct load and inflation data, see the Tire and Rim Association Load and Inflation Table, ETRTO or JATMA standards.
The load-bearing capacity of the replacement tire shall not be lower than that of the supporting tire
It must be ensured that the load capacity of the replacement tire is equal to or greater than the value specified by the manufacturer of the supporting tire.
Note: Eurometric and P-metric passenger tires manufactured and/or sold by Goodyear are not interchangeable with other types of tires unless the cross-sectional width, flatness ratio and rim diameter are the same as Goodyear tires.
Note: It is not allowed to replace the "standard load" tires with "super heavy load" tires. If the supporting tires are "super heavy load" tires, they should also be replaced with super heavy load tires of the same size.
In addition, the following principles should also be followed:
When installing two tires, install the tire with a large tread depth on the rear axle.
If radial or non-radial tires must be installed on the same vehicle, install the radial tires on
the rear axle. Do not mix radial and non-radial tires on the same axis.
When snow or all-weather tires are required to improve vehicle performance, be sure to install such tires on all four wheels.
It is not recommended to install tires with different speed limits.
If tires with different rated speeds are installed, the two tires on the same shaft should have the same rated speed.

Tires with low rated speed limit the speed capability of the vehicle.

When you want to change the tire size, be sure to consult the dealer to understand the appropriate rim width, and carefully check the distance between the vehicle and the tire. Vehicles must not be overloaded.
For the vehicle load limit, please refer to the owner's manual. Being overweight puts extra stress on tires and other key components of the vehicle. This may also result in reduced operability, increased fuel consumption, and tire failure. Tire overload can also cause severe rupture, component separation, or flat tires. The load capacity of the new tire must not be lower than the value marked on the tire label. Remember that the appropriate rim width is critical to the proper distribution of load and the performance of the tire. When used on a light truck, utility vehicle, or trailer, the maximum load capacity marked on the sidewall of the tire should be reduced by 10%. If it is specified to be replaced by a light truck tire, then P-metric tires must not be installed on the light truck.
Maintain suspension, wheel positioning and dynamic balancing, and rotate tires.
Failure to regularly change tires, wear of suspension components, and vehicle dynamic balance and inaccurate positioning can cause excessive vertical vibration or uneven tire wear. According to the recommendations of the vehicle manufacturer, or at least every 10,000 kilometers traveled to change the tires.
