2.36 TYRES
Read 0.5.1 (GENERAL PRECAUTIONS AND
INFORMATION) carefully.
Check tyre condition after the first 1000 km (625 mi) and
every 7500 km (4687 mi) or 8 months afterwards.
Tyre inflation pressures should be checked monthly with
the tyres at room temperature.
This vehicle is fitted with tubeless tyres.
TREAD CONDITION
WARNING
Inspect tread surface and check for wear. Badly worn
tyres adversely affect traction and handling.
Always change a worn tyre. A tyre that becomes
punctured in the tread area should be changed when
the puncture is larger than 5 mm.
Some of the tyre types approved for this vehicle are
fitted with wear indicators.
There are various types of wear indicators.
Enquire about correct wear inspection procedure
with your supplier.
Never use tube tyres on tubeless tyre rims, or
viceversa.
Always check that the caps are in place on the valves
(1), or the tyres may deflate suddenly.
Tyre replacement and repair, and wheel servicing
and balancing are delicate operations. They should
be carried out using adequate tools and are best left
to experienced mechanics.
MINIMUM RECOMMENDED TREAD DEPTH (A):
front and rear tyre ºººººººº2 mm ( 3 mm).
INFLATION PRESSURES
Check the tyre inflation pressures at regular intervals
when the tyres are cold.
Checking pressure on hot tyres will result in inaccurate
measurement.
Take care to check tyres pressures before and after a
long journey.
An overinflated tyre will provide a harsh ride, reduce
riding comfort and stability when cornering.
An underinflated tyre will extend the contact patch to
include a larger portion of the tyre wall (2). When this is
the case, the tyre may slip on or become separated from
the rim, leading to loss of control. The tyre may even
jump off the rim under hard braking.
Lastly, the vehicle may skid in a bend.
See 1.5 (SPECIFICATIONS) for inflation pressures.
WARNING
The wheel must be balanced after each tyre repair.
New tyres may be coated with an oily film. Drive
carefully until covering several kilometres.
Never apply non-specific products to the tyres.
Approved tyre sizes are reported in the registration
document. Installing non-approved tyres is a legal
offence.
Using tyres other than the specified sizes may
change vehicle behaviour, impair handling and make
the vehicle unsafe to ride.
Use only the first-equipment tyre types selected by
aprilia, see 1.5 (SPECIFICATIONS).
