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.

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.

F - Owner Maintenance
1-F-55 Aston Martin recommends the use of 'AUTOGLYM' car care products or
preparations of similar reputable manufacture for adding to the washing
water. The use of mild 'detergents' as directed by the manufacturers will also
help. When dust and mud have been removed with a hose brush and water,
finally dry with a chamois leather, which should be rinsed regularly in clean
water.
WARNING: Washing and polishing agents containing silicone should not be
applied to glass. This will reduce the efficiency of the windscreen wipers, causing
smears which will reduce visibility, particularly during darkness and in the rain.
During the winter months, it is advisable to wash the car more frequently,
paying particular attention to the underside to combat the detrimental
effects of any salt and sand contamination picked up from treated roads.
Polishing
Approximately twice a year, a good quality polish should be applied and
then buffed, using a soft lint-free cloth.
Alloy wheel rims should be treated with a cleaner which is specifically
manufactured for this purpose.
