The Pewag snow chains RS9 79 Servo 9 are only 9 mm thick on the internal side and therefore particularly suitable for vehicles with tight wheel wells. They are ideal for city driving and paved roads, and recommended for vehicles with front-wheel drive. The Pewag servo ratchet tensions the chain automatically - manual tensioning is not necessary, and it has 3 mm D-shaped steel links. The self-opening inside lock is fast and easy to use. This model fits tyre sizes: 225/80 R15, 235/75 R15, 245/70 R15, 215/80 R16, 225/70 R16, 225/75 R16, 235/70 R16, 255/60 R16, 225/65 R17, 245/55 R17, 255/55 R17, 225/60 R18, 235/55 R18, 245/50 R18, 265/45 R18, 225/55 R19, 235/50 R19, 245/40 R20.
