Tires The ABS works by comparing the speed of the wheels. When replacing tires, use the same size originally supplied with the vehicle. Tire size and construction can affect wheel speed and may cause the system to activate. When the tires are rotated, make sure the air pressures are checked. It is best to replace all four tires at the same time. If that is not possible or necessary, replace the two front tires or two rear tires as a pair. Replacing just one tire can seriously affect your vehicle's handling. If you ever replace a wheel, make sure that the wheel's specifications match those of the original wheels. Also be sure you use only TPMS specific wheels. If you do not, the tire pressure monitoring system will not work. 504 2009 Pilot
