When carrying out regular maintenance or replacing tyres, check the state of the wheel rims.
Visually inspect the external and internal wheel rim surfaces; if cracks or deep gouges are noted, replace
the wheel.
In the case of scratching, minor dents or superficial scuffs, repaint the affected area or, if necessary, the
entire rim. Use the standard procedure for repainting an alloy wheel, applying a coat of silver based
paint then, once the coat had dried to a matte finish, applying a layer of clear coat. Dry the wheel in the
oven to polymerise the layers of paint applied.
Cover the valve mounting and the hub badge when repainting, as the additional thickness of the paint
may impede correct assembly and compromise the effectiveness of the corrosion treatment applied.
Take particular care around the mating surface with the brake disc; this area is only coated with a single
layer of cataphoresis film.
This treatment has a limited lifespan as the film is gradually eroded by fretting between the surfaces. This
area cannot be repainted and a rim with a deteriorated film must be replaced.
Before refitting, always check that the mating surfaces between the wheel and the brake disc are perfectly
clean.
Using inappropriate tools for removing and refitting the tyre may damage the wheel rim and
compromise the protective layer.
Balance the wheel without the tyre but with the pressure sensor and valve installed: if, after removing the
balancer weights, the values for static balance exceed 36 (including vertical bouncing and wobble), the
rim must be replaced.
Refitting the tyre
Ensure that tyres are not kept in stock for more than 4 years. Tyres may be kept in stock for a
maximum of 4 years, provided that they are kept out of direct sunlight, protected from the weather
and humidity and stored in low oxygen conditions. If necessary, the Ferrari Service Network will
verify whether old tyres are suitable for use. In all cases, tyres mounted on a vehicle for over 3
years must be inspected by an authorised Ferrari Service Centre.
Tyre replacement is recommend after 4 years of normal use. Frequent use in maximum load
conditions and at high temperatures may lead to premature deterioration.
When removing and refitting tyres, DO NOT use tyre levers which could damage the rim and
compromise its protective layer. Use levers coated in protective material.
