How Often Should the Tires on a Mondeo Be Replaced?

The lifespan of Mondeo tires is typically three years or 80,000 kilometers, but this can vary depending on the condition of the tires. If the tires show signs of bulging or if the tread is excessively worn, it is recommended to replace them earlier. Tires are one of the most critical components of a vehicle, usually mounted on metal rims. They support the vehicle's weight, absorb external shocks, ensure contact with the road, and maintain driving performance. Tires serve the following functions: 1. Support the entire weight of the vehicle, bear the load, and transmit forces and moments in other directions. 2. Transmit traction and braking torque, ensuring good adhesion between the wheels and the road to enhance the vehicle's power, braking, and off-road capabilities. 3. Protect automotive components from severe vibrations and premature damage, adapt to high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel efficiency.
