At Tyres.co.uk, tuned SQ5 options include 255/45 R20 105W XL Michelin Pilot Sport 4 SUV, which is the default 20-inch OEM size on the 2020 SQ5 TDI, as well as the Pirelli P Zero (PZ4). Make sure your registration, placard, and current tyres are in order because other SQ5 wheel options might require them.
To find out SQ5 wheel size, look at the tyre size placard located on the B pillar of the driver side, just out of reach when the door is closed. The placard has the approved sizes and pressure ratings of tyres for the vehicle. For other tyre configurations and/or if other wheels are installed on the SQ5, look at the sidewall of the tyres and the vehicle registration.
Because Audi SQ5 models use quattro, all four tyres must have close to the same rolling circumference and close to the same tread depth. Although it is not always necessary to replace all four tyres, they should be replaced in pairs on the same axle. If two new tyres are being fitted, UK safety guidelines recommend the tyres should be fitted to the rear axle.
