TREAD CONDITION
WARNING
Inspect tyre surface condition and check for
wear, as worn tyres lead to poor road holding
and handling.
Change the tyre when worn or punctured, if the
puncture in the tread is larger than 5 mm (0.19
in.).
Some of the tyres approved for this vehicle are
equipped with wear indicators.
There are several kinds of wear indicators.
Contact your dealer for instructions on how to
check tyre wear.
Do not install tyres with air tube on rims for
tubeless tyres and vice versa. Always check
that the caps are in place on the valves (1), or
the tyres may deflate suddenly.
Tyres changing, repair, maintenance and
balancing must be carried out by specialised,
knowledgeable
equipment.
Have the wheel balanced after repairing a tyre.
New tyres may be coated with an oily residue;
ride with extra care until covering a few
kilometres. Do not oil the tyres with unsuitable
fluids.
Tyre size is reported on the registration
document; using any tyres other than those
specified is illegal.
Using tyres of a size other than specified may
alter vehicle
handling and vehicle safety.
Use only tyres of the same type as the first-
equipment tyres selected by aprilia, see
(TECHNICAL DATA).
