The type of car you drive dictates whether you can get away with two tires or if you need four.
: Differing tread depths on the same axle can cause the vehicle to veer to one side during emergency stops. do you have to buy tires in pairs
: Modern safety systems like Anti-lock Braking (ABS) and Electronic Stability Control (ESC) rely on consistent wheel speed data. Large differences in tire diameter can confuse these sensors. 2. Drivetrain Matters: 2WD vs. AWD The type of car you drive dictates whether
: Mismatched tires can lead to "darting" or unstable steering because one side of the car has significantly more traction than the other. Large differences in tire diameter can confuse these sensors
Replacing tires in pairs—specifically on the same axle—ensures that the car remains balanced during braking and cornering.
of an inch) can cause the tires to spin at different speeds, which puts immense stress on the drivetrain and can lead to expensive differential failure. 3. When It’s Safe to Replace Just One
: Most AWD manufacturers, like Subaru and Audi, require replacing all four tires at once. Even a small difference in tread depth (often as little as
