New tires are recommended to be installed on the drive wheels, as this can enhance the vehicle's steering, driving, and handling performance. Tires are wear-prone components and need to be replaced after a certain mileage or period of use. Generally, tires are replaced in pairs to ensure even wear on both sides of the vehicle, improving stability and reducing safety risks. Here is additional information: 1. Rear-wheel drive vehicles: place new tires on the rear wheels. For rear-wheel drive vehicles, the rear tires typically experience more wear and tear, leading to reduced traction and an increased risk of skidding. Therefore, when replacing tires, it is advisable to install new tires on the rear wheels. If the rear tires are not significantly worn or aged, they can be rotated to the front. 2. Four-wheel drive vehicles: place new tires on the front wheels. For four-wheel drive vehicles, it is still recommended to install new tires on the front wheels. Even though all four tires share the driving load, the front wheels also bear the responsibility for steering. If you want to avoid steering issues, it is best to place new tires on the front wheels.

Whether to put new tires on the front or rear wheels actually depends on the vehicle's drivetrain. For front-wheel-drive cars, new tires should be prioritized on the front wheels, as they handle steering and power transmission, wearing out faster; new tires provide better grip and handling. For rear-wheel-drive vehicles, it's the opposite—placing new tires on the rear wheels enhances traction for the drive wheels. For all-wheel-drive cars, it's best to replace all four tires simultaneously to avoid differences in friction coefficients between old and new tires damaging the drivetrain. My experience suggests that, regardless of the vehicle type, never split two new tires between the front and rear, as this can disrupt the vehicle's balance. It's advisable to have a professional technician assess the wear of the old tires before deciding on the installation position during a tire change.

From a driving safety perspective, newly replaced tires should be prioritized on the drive wheels. For front-wheel-drive vehicles, front tire wear is typically 1.5 times that of the rear tires, and delayed replacement can lead to hydroplaning in rainy conditions. Last time, I encountered a car owner who installed new tires in the wrong position, resulting in longer emergency braking distances. For rear-wheel-drive vehicles, insufficient rear tire grip can easily cause oversteer. Nowadays, new tires come with wheel speed sensor slots, and incorrect installation may trigger false alarms. Here’s a handy tip: after changing tires, sprinkle a small amount of flour on the tread to check for even wear and promptly identify alignment issues.

Changing tires depends on the specific condition of the vehicle. My principle is: if you drive aggressively, put the new tires on the drive wheels. For front-wheel-drive cars, new tires should go on the front for more precise steering; for rear-wheel-drive cars, they should go on the rear for better acceleration. If the old tires are already worn down to the tread wear indicators, even the best new tires won't help if placed incorrectly. I conduct a thorough tire inspection every quarter, including measuring tread depth and checking for uneven wear. Here's a maintenance tip: after installing new tires, remember to reset the tire pressure monitoring system. Nowadays, systems with self-learning functions can be adjusted via smartphone, making it much more convenient.

Nowadays, tire quality is generally good, but incorrect installation can be costly. For front-wheel-drive cars, installing new tires on the rear wheels can cause the front end to sink and lose control during acceleration. For rear-wheel-drive cars, installing them on the front can lead to understeer during turns. I recommend replacing at least two tires simultaneously to ensure the tread depth difference is less than 3 mm. A tire shop technician taught me a trick: mark the installation date on the tire sidewall with chalk and check for even wear after six months. Some high-performance tires with directional indicators can become particularly dangerous if installed backward, as their water drainage performance deteriorates. Remember, regular tire rotation can extend tire life by 20%.
