16.8 WHEELMAINTENANCE
Use only TubeLess 4-ply (4PR) tyres in sizes 20x10.00-8 for the front and
15x6.00-6 for the rear.
Routinelycheckthetyreinationpressure,whichshouldbe1.5bar(21
psi) for all four wheels.
Always ensure that the valve protection cap is in place. The purpose of
the cap is to prevent foreign bodies from entering the valve, damaging it
and causing pressure loss; always tighten the cap by hand.
In the event of impacts against curbs or other obstacles, it is important
to visually check the condition of the tyres: a bulge in the sidewall, for
example, may indicate an internal structural damage that would make the
tyre unusable.
