Jeg forstår ikke hvorfor denne diskusjonen aldri tar slutt. I manualen som følger med bilen står det klart og tydelig hva som gjelder visco. I følge den [manualen] skal du
absolutt sette de beste dekkene foran.
Dette er fra -01-manualen:
pg. 101 Wheels and tires - All Wheel Drive vehicles
Types of Tires
Always drive on tires of identical brand, size, construction (radial), tread pattern, load-, speed-, traction-, temperature-, and treadwear rating. Never drive on mixed tires, except for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and inflation pressures are shown on the tire pressure label located inside the fuel filler door.
CAUTION:
Failure to always drive on properly inflated, identical tires of correct dimensions may result in a circumference difference between tires on the front and rear axles. This will cause excessive tire wear and may damage the transmission and all-wheel-drive system.
Tire Replacement
When tire replacement is necessary, Volvo strongly recommends replacing all four tires at the same time with identical tires as explained above. Failure to do so can result in a circumference difference that may damage the transmission and all-wheel-drive system.
If only one or two tires are replaced, the new tire(s) must be identical to the tires with which the car was built, and must be mounted on the FRONT AXLE ONLY! Failure to do this may damage the transmission and all-wheel-drive system.
Tire Rotation
Volvo recommends rotating the tires every 7,500 miles (12,000 km). Tires should be rotated front-to-back/back-to-front only. Tires must maintain the same direction of rotation throughout their lifetime, and should never be rotated from one side of the vehicle to the other.
CAUTION:
Failure to rotate tires at recommended intervals will cause uneven tire wear and may damage the transmission and all-wheel-drive system.
