Tire Condition; Winter Tires - Mini Clubman Owner's Manual

Tire condition

Inspect your tires regularly for tread wear, signs
of damage and for foreign objects lodged in the
tread. Check the tread depth.
Tread depth
The tread depth should not drop below 1/8 in/
3 mm, although, for example, European legis-
lation only specifies a minimum tread depth of
1/16 in/1.6 mm. At tread depths below 1/8 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.

Winter tires

When winter tires wear down past a tread depth
of 1/6 in/4 mm, they become perceptibly less
suitable for winter conditions. In the interest of
safety, new tires should be installed.
Minimum tread depth
Wear indicators in the base of the tread groove
are distributed around the tire's circumference;
the letters TWI, for Tread Wear Indicator, on the
tire's sidewalls identify tires that incorporate
these wear indicators. When tire tread is worn
down to the level of the wear indicators, the
remaining tread depth is 1/16 in/1.6 mm.
Tire damage
Due to low-profile tires, please note that wheels,
tires and suspensions parts are more susceptible
to road hazards and consequential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or

some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immediately
and have wheels and tires thoroughly
checked. To do so, drive carefully to the nearest
MINI dealer or a specialized tire shop that has
specially trained personnel working in accor-
dance with the specifications of the MINI manu-
facturer. If necessary, have the vehicle towed
there.
Otherwise, tire damage can be extremely dan-
gerous for vehicle occupants and other road
users.<
Tire age
The manufacturing date of tires is contained in
the tire coding:
DOT ... 2011 means that the tire was manufac-
tured in week 20 of 2011.
For various reasons, such as the development
of brittleness, the manufacturer of your MINI
recommends tire replacement after no more
than 6 years, regardless of the actual wear of the
tires.
Run-flat tires
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall.
Run-flat tires comprise a conditionally self-sup-
porting tire and a special rim. The reinforcement
in the sidewalls ensures that the tire can con-
