Important Safety Information

Winter Tyres
Two options are available to equip your DB AR1 for winter motoring.
Snow Tyres - The recommended snow tyres fit to the normal 8 inch front
wheel rims. Four 8 inch front wheel rims and winter tyres are required to
fully equip the car for severe weather driving. (See the Specifications section
of this Owner's Guide).
Snow Chains - These are available from your Aston Martin dealer and will
fit only the 8 inch road wheels fitted with snow tyres.
United States Department of Transportation
Uniform Tyre Quality Grades
The following information relates to the tyre grading system developed by
the National Highway Traffic Safety Administration which will grade tyres by
tread wear, traction and temperature performance.
All passenger car tyres must conform to federal safety requirements in
addition to these grades.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the
tyre when tested under controlled conditions on a specified government test
course. For example, a tyre graded 150 would wear one and a half times as
well on the government course as a tyre graded 100. The relative performance
of tyres depends upon the actual conditions of their use, however, and may
depart significantly from the norm due to variations in driving habits, service
practices and differences in road characteristics and climate.
