PCR tires, which stand for Passenger Car Radial Tires, are designed for daily use vehicles where comfort, fuel economy, and flexibility matter most. Competition tires on the other hand are designed for racing and so they have unique tire compounds and tread designs that promote high speed and outstanding grip on the racing surface. This is important as it helps one in making an informed decision on which option to go for depending on their tire needs. Everyday use tires are the PCR tires while the competition tires are made for racing conditions. Be wise and choose accordingly to your driving pattern and the environments.
