Driving with compact wheel
Do not exceed a speed of
50 mph/80 km/h.
Drive conservatively and do not exceed a
speed of 50 mph/80 km/h. Otherwise, changes
in the driving characteristics could result, for
example reduced track stability on braking, ex‐ tended braking distance, and altered self-
steering characteristics in the limit range. In
conjunction with winter tires, these character‐
istics are more pronounced.◀
Only mount one compact wheel
Only one compact wheel may be
mounted. Restore the wheels and tires to their
original size as quickly as possible. Failure to
do so is a safety risk.◀
