When buying tires, pay attention to: 1. Know the suitable tire type for your car; 2. Understand the tire size of your car, which is marked on the side of the tire; 3. Check whether the purchased tire is a retreaded one, and pay attention to the production date of the tire. The functions of car tires: 1. Ensure good ride comfort and smooth driving; 2. Ensure good adhesion between the wheels and the road surface, improving the traction, braking, and passing ability of the car; 3. Transmit driving force, braking force, and steering force through the tires to achieve car operation; 4. Support vehicle loads; 5. Reduce and absorb the vibration and impact force during car driving.

When buying tires, I've gone through the process multiple times. First, check the tire size to ensure it matches the rim—neither too big nor too small; otherwise, it won't fit or could compromise safety. Next, consider the tire type. I live in the north where winters are snowy, so I opt for winter tires and switch to summer tires in warmer months for better grip—otherwise, slipping becomes a risk. Additionally, tread depth is crucial; it should be at least 4mm or more. Shallow treads increase braking distance, making rainy conditions hazardous. As for brands, I prefer reputable ones like Michelin for reliable quality—don’t skimp on cost. Lastly, don’t forget to check the speed rating and load index against your vehicle’s manual, or high-speed stability will suffer. Post-installation, wheel balancing and alignment are also essential to prevent vibrations. These are fundamental for safe driving—never cut corners.

As a frequent driver, when purchasing tires, I prioritize performance indicators, such as the speed rating must be at least H, and the load index should suit my vehicle's weight; otherwise, the handling feels poor during sharp turns or at high speeds. I also pay attention to the tread design, opting for deep grooves to reduce the risk of hydroplaning and enhance safety in rainy conditions. Climate factors are crucial: if traveling to different places often, all-season tires are more practical. In terms of brands, I've tried Goodyear, which offers strong grip but at a slightly higher price, so I choose models with better cost performance. The installation process cannot be skipped—new tires must be balanced and aligned after mounting, otherwise, they may produce noise and affect lifespan. Regular maintenance, like checking tire pressure and wear, can extend usage time and save costs.

From a safety perspective, the primary consideration when purchasing tires is ensuring accurate sizing. Tires smaller than the original ones will wear out faster, while larger ones may be difficult to install. Tread depth should be at least 3mm; shallow treads increase the risk of slipping in rainy conditions. Avoid buying used tires due to their high risk. DOT certification is essential to ensure quality compliance. Choose tire types that match the climate: winter tires for northern regions to prevent slipping, while summer tires suffice in the south. Also, pay attention to the speed symbol; for example, T-rated tires are suitable for city driving, while higher speeds require higher ratings. Within your budget, opt for reliable brands to avoid accidents. During installation, check for any wheel rim deformation that could affect balance.
