Frequently Asked Questions About Tire Installation and Maintenance
Can I Do the Assembly of The Tire I Bought to The Rim by Myself?
Removing old tires from the rims and installing new tires is not an end-user operation and is dangerous. Tire mounting using unsuitable tools or methods can result in a tire puncture, which can cause severe injury or death. Qualified tire fitting service professionals should only do tire fitting. Tire mounting should never be attempted without appropriate training, tools, and equipment.
How Often Should I Check My Tires' Air Pressure?
Check the air pressure in your tires (including the spare tire) once a month before long trips or carrying extra loads. Be sure to use an accurate and reliable pressure gauge. Always check and top up the pressure of your vehicle's tires when they are "cold." Tires are considered “cold” if the car has been parked for three hours or more or if the vehicle has been driven less than 1.6 km (1 mile) at an average speed.
How Should I Adjust the Pressure of My Tires? How Many Psi (How Many Bar) Should I Air?
Always inflate and use your tires (including the spare) to the pressure recommended by the vehicle manufacturer. You can find the vehicle manufacturer's recommendation in the owner's manual or on the nameplate. Depending on the make/model of your vehicle, the nameplate may be located inside the fuel filler flap, inside the driver's door, in the trunk, etc.
What Does Tire Speed Index Mean?
Each tire carries a letter denoting its "speed index." This index shows the speed capacity of a tire according to standard laboratory tests. The speed rating system aims to allow the speed capabilities of different tires to be compared. When changing your tires, you can decide on the speed index by looking at your vehicle's owner's manual or tire information label. You can also use the speed index of your old tires if the tires on your car are the first ones fitted at the factory or if you are sure that the vehicle manufacturer's recommendations have been considered with each change. Your new tires should also have at least the same speed index. It's okay to use a higher speed index, but it's not necessary. Using a higher speed index may adversely affect your vehicle's fuel consumption, cabin noise level, etc., in some conditions.
What Should I Do If Cords Appear in My Tires?
If you notice any damage or unusual conditions in your tires (the cord fabric becomes visible, the ends of the wires come off, bubbles, etc.), contact a qualified and authorized tire service to have your tires checked as soon as possible. It may be necessary to remove the tire from the rim for a complete check. Do not continue to use your vehicle without these checks.
Is the Use of Nitrogen Gas Recommended for Inflating Tires?
Nitrogen is an acceptable inflation gas for passenger, light commercial, and truck tires by leading tire manufacturers such as Bridgestone, Lassa, Dayton, Firestone. Compared to air, it is recommended to be used because the volumetric expansion rate of nitrogen with heat is very low, and it does not have the effect of causing corrosion (rusting) of the wires in the tire like air over time.
