The manufacturer of your BMW recom-
mends that all tires, i.e. including the
spare wheel, be replaced regardless of
the actual wear after 6 years at the lat-
est.
Tread wear
The tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
Belted construction radial
Rim diameter in inches
Load index,
not with ZR tires
The tire's date of manufacture is indi-
cated on the sidewall:
Speed code letter,
with ZR tires before the R
For example, a tire graded 150 would
wear one and one-half, 1γ, times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.
DOT... 3603 indicates that the tire was
manufactured in week 36 of 2003.
Speed code letter:
Q = up to 105 mph/160 km/h

Uniform Tire Quality Grading

applicable on the tire sidewall between
tread shoulder and maximum section
