11-26 Maintenance and service/Tires and wheels pressure. NOTE . Correctly inflated tire (tread worn evenly) . Under inflated tire (tread worn on the shoulders) Roadholding is good, and steering is responsive. Rolling resistance is low, so fuel consumption is also lower. Rolling resistance is high, so fuel con- sumption is also higher. . The air pressure in a tire increases by approximately 4.3 psi (30 kPa, 0.3 kgf/cm 2 ) when the tire becomes warm. . The tires are considered cold when the vehicle has been parked for at least 3 hours or has been driven less than one mile (1.6 km). WARNING Do not let air out of warm tires to adjust pressure. Doing so will result in low tire pressure. Incorrect tire pressures detract from con- trollability and ride comfort, and they cause the tires to wear abnormally.
