Maintenance and care359

Notes onrotating wheels
\nWARNINGRisk of injurythrough differ‐ent wheel sizes
Interchangingthe front andrear wheels ifthewheels or tires havedifferent dimensionsmay severely impairthe drivingcharacteris‐tics.
The wheel brakes or wheel suspension com‐ponents may also be damaged.
Rotatefront andrear wheels onlyifthewheels and tires are ofthe same dimen‐sions.
Thewear patterns onthe front andrear wheelsdiffer:
RFront wheelswear more onthe shoulder ofthe tire
RRear wheelswear more inthe center ofthetire
Onvehiclesthat havethe same size front andrear wheels,rotatethe wheels accordingtotheintervals inthe tire manufacturer'swarranty
book inyourvehicle documents. Ifthis is notavailable,rotatethe tiresevery3,000to6,000 miles (5,000to10,000 km),depending onthewear. Ensurethatthe directionofrotation is maintained.
It is imperativetoobservethe instructions andsafety notes on "Changing a wheel" when doingso Preparingthevehiclefor a wheelchange(page415).
