Audi SQ7 tyre options at Tyres.co.uk include the Michelin Pilot Sport 4 SUV and Pirelli P Zero in 285/40 R21 109Y XL for SQ7 models with factory 21-inch wheels. Confirm the registration and tyre-pressure placard before ordering, as wheel options vary and the required load, speed and XL specification must be retained.
Audi SQ7 tyre specifications can be found on the tyre-pressure placard located on the driver-side B-pillar near the driver's door; and repeated pressure info is in the fuel flap. The placard details the approved tyre sizes, load ratings, and pressure specifications for the wheels equipped on the vehicle.
You do not always have to replace all four tyres on an Audi SQ7, but tyres should be replaced at least in pairs on the same axle. Every Audi SQ7 has quattro four-wheel drive, therefore all four tyres must be of the same brand, construction and tread pattern. If only two new tyres are fitted, they must be placed on the rear axle.
