Not all cars require replacing both tires when changing them, but for safety reasons, it is best to replace both tires together. The brand, specifications, tread pattern, and structure of these two tires should be consistent. Additionally, it is recommended to install the new tires on the drive wheels. Relevant information about car tires is as follows: 1. Introduction One: The main functions of tires are to support the entire weight of the vehicle, bear the load of the car, transmit traction and braking torque, ensure the adhesion between the wheels and the road surface, reduce and absorb vibrations and impact forces during driving, prevent severe vibrations and early damage to car components, adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency. 2. Introduction Two: Tires are usually composed of three parts: the outer tire, inner tube, and flap. There are also tires that do not require an inner tube, with an inner layer of the tire body having a rubber layer with good airtightness, and requiring specialized rims. Tire structures worldwide are developing towards tubeless, radial structures, flat (small ratio of tire section height to width), and lightweight designs.

I often handle these kinds of issues when helping out at the auto repair shop. Changing a tire usually refers to replacing the outer tire part, which is the rubber casing, while the wheel rim or steel rim generally remains untouched. Most modern vehicles use a tubeless design. During the operation, we first use a pry bar to remove the old tire, then install the new one, followed by inflation and dynamic balance testing to prevent high-speed vibrations. Only if the wheel rim is deformed or severely damaged would the entire wheel need to be replaced. Remember, ignoring tire issues can lead to unstable driving or blowouts. Regularly checking tire pressure and tread depth can extend their lifespan, saving money and ensuring safety. After the replacement, getting a wheel alignment adjustment ensures smooth driving—that’s the smart move.

What is the purpose of vehicle anti-skid control?

Vehicle anti-skid control function: Primarily controls the longitudinal and lateral stability of the vehicle to ensure it moves according to the driver's intentions. When tires are about to lock up during braking, the ESP system performs "mechanical cadence braking" with hundreds of braking actions per second. This allows the vehicle to maintain steering control via the steering wheel even during full-force braking. The ESP works in coordination with the engine ECU - when drive wheels slip, the engine ECU immediately reduces throttle intake to lower engine RPM and decrease power output, while the ESP ECU applies braking to the slipping drive wheels. This helps minimize slippage and maintain appropriate power output for optimal tire-road traction.

Do tires with cracks need to be replaced?

Tires with minor cracks do not need to be replaced. It is recommended to replace tires every 5 to 6 years, or approximately every 80,000 kilometers based on mileage. The typical lifespan of a tire is five years, and small cracks may appear after about three years of use. If the cracks are minor and located on the tread of the tire, they are considered normal signs of aging, cracking, or wear and do not require replacement, but regular inspections are still necessary. However, if cracks appear on the sidewall of the tire, it is important to have it checked at a service center promptly and replaced if necessary, as the sidewall is the most vulnerable part of the tire and continued driving may lead to a blowout. Additionally, if the cracks are too long or deep, reaching the standard tread depth of 1.6 millimeters, replacement is also required.
