Maintenance and Care Owner Maintenance The Tire Pressure Monitoring System í does not alleviate the need to check the tire condition every day, including whether the tires all look inflated properly. Inspect all tire pressure monthly (including the spare í) when the tires are cold. Maintain recommended pressures for the best ride, handling, and minimum tire wear. When checking the tire pressures, use of a digital tire pressure gauge is recommended. NOTE l l l l Always check tire pressure when tires are cold. Warm tires normally exceed recommended pressures. Don't release air from warm tires to adjust the pressure. Underinflation can cause reduced fuel economy, uneven and accelerated tire wear, and poor sealing of the tire bead, which will deform the wheel and cause separation of tire from rim. Overinflation can produce a harsh ride, uneven and accelerated tire wear, and a greater possibility of damage from road hazards. Keep your tire pressure at the correct levels. If one frequently needs inflating, have it inspected. qTire Rotation To equalize tread wear, rotate the tires if irregular wear develops. According to the scheduled maintenance charts.Refer to Scheduled Maintenance on page 8-3. During rotation, inspect them for correct balance. NOTE Because your vehicle is not equipped with a spare tire, you cannot do a tire rotation safely with the jack that comes with your vehicle. Have an Authorized Mazda Dealer perform tire rotation. Refer to the specification charts (page 10-6). í Some models. 8-23
