Operation Tires and wheels Rotating tires If applicable to your vehicle's tire configuration, tires can be rotated according to the tire manufacturer's recommended intervals in the tire manufacturer's warranty pamphlet located in your vehicle literature portfolio. If none is available, tires should be rotated every 3000 to 6000 miles (5000 to 10000 km), or sooner if necessary, according to the degree of tire wear. The same rotation (spinning) direction must be maintained ( page 287). Rotate tires before the characteristic tire wear pattern becomes visible (shoulder wear on front tires and tread center wear on rear tires). Thoroughly clean the mounting face of wheels and brake disks, i.e. the inner side of the wheels/tires, during each rotation. Check for and ensure proper tire inflation pressure. Warning! G Warning! G Rotate front and rear wheels only if the tires are of the same dimension. If your vehicle is equipped with mixed-size tires (different tire dimensions front vs. rear), tire rotation is not possible. Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 80 lb-ft (110 Nm). Only use genuine Mercedes-Benz wheel bolts specified for your vehicle's rims. Tire rotation can be performed on vehicles with tires of the same dimension all around. If your vehicle is equipped with tires of the same dimension all around, tires can be rotated, observing a a front-to-rear rotation pattern that will maintain the intended rotation (spinning) direction of the tire ( page 287). In some cases, such as when your vehicle is equipped with mixed-size tires (different tire dimension front vs. rear), tire rotation is not possible. For information on wheel change, see the "Practical hints" section ( page 329) and ( page 353). 289
