Temperature
The temperature grades are A, the highest, B, 
and C, representing the tire's resistance to the 
generation of heat and its ability to dissipate 
heat when tested under controlled conditions 
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the 
material of the tire to degenerate and reduce 
tire life, and excessive temperature can lead to 
sudden tire failure. The grade C corresponds to 
a level of performance which all passenger car 
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A 
represent higher levels of performance on the 
laboratory test wheel than the minimum 
required by law.
The temperature grade for this tire is 
established for a tire that is properly 
inflated and not overloaded. Excessive speed, 
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat 
buildup and possible tire failure.
<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear, 
signs of damage and foreign objects lodged in 
the tread, and check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of 
0.063 in/1.6 mm. At tread depths below 0.12 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 noticeably loose their suitability for 
winter use below a tread depth of 0.16 in/4 mm. 
New tires should be mounted in the interest of 
safety.
Wear indicators at the tread-groove base, refer 
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire 
with TWI – Tread Wear Indicator. If the tire tread 
has been driven down to the wear indicators, a 
tread depth of 0.063 in/1.6 mm has been 
reached.
Wheel/tire damage
Please note that low-profile tires cause wheels, 
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
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. These 
kinds of problems may also be signaled by other 
changes in vehicle response, such as a strong 
tendency to pull to the left or right.
In these cases reduce your speed imme-
diately and have the wheels and tires 
inspected immediately. To do this, carefully 
drive to the nearest BMW center or a special-
ized tire dealer that works in accordance with 
BMW guidelines and uses appropriately trained 
personnel. Have the vehicle towed to the repair 
shop if necessary. Tire damage can be 
extremely dangerous to vehicle occupants and 
other road users.
