What you do or what you drive and where you drive will help you in the selection process while deciding on either the PCR tires or all terrain tires. Generally, PCR tires are good for fuel efficiency and comfortable driving when used on the highways and in cities. All terrain tires on the other hand are designed for those who go out for off and on-road challenges, providing resistance to wear unlike all terrain tires. Knowing and understanding your individual needs will enable you to choose a tire that suits your driving style.
