Regardless of the load of the Ford SUV and its extra modest mechanics, the Explorer nonetheless allowed me to maintain up with the small group of sports activities vehicles. After all, the Primacy tires screamed within the corners, however at no time did they offer me the impression they had been going to let me down.
