Should I Replace Two or Four Tires?
2 Answers
It is recommended to replace all four tires together. More information about tires is as follows: 1. The specific replacement cycle of tires depends on their usage, but the service time should not exceed 6 years. 2. When replacing tires, use tires with the same size, speed rating, and load capacity as the original tires. 3. The function of tires is to support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 4. Tires transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the car's power, braking, and passability.
I'm the type of person who prioritizes safety above all else, so when it comes to tires, I recommend replacing all four with new ones. Think about it—having mismatched tire wear can lead to significant differences in traction, especially on wet roads or during sharp turns, causing uneven grip that may result in skidding or loss of control. While replacing just two tires might save you some money upfront, the older tires will accelerate the wear on the new ones, costing you more in the long run. Last time I only replaced the tires on the front drive axle, and the rear tires wore out so quickly that I had to replace all of them within months. Check the tread depth of all your tires—if they're all past the safety limit (e.g., below 1.6mm), it's best to replace them all at once. This ensures even wear, better fuel efficiency, and peace of mind for a safer drive.
