Tyres.co.uk offers Audi RS Q8 tyres with Pirelli P Zero (PZ4) and Michelin Pilot Sport 4 SUV in 295/35 R23 108Y XL which is a 23-inch factory fitment. Make sure you include your exact registration's wheel size and load index, speed rating, and XL specification, before placing your order.
You will find the tyre size for the Audi RS Q8 on the driver side tyre pressure sticker. This sticker will have the permitted wheel and tyre combination along with the load and pressure settings. The sidewall of the current tyre has the size, load index and speed rating of the tyre.
All variants of the Audi RS Q8 have quattro all-wheel-drive systems, so all four must be of the same size, construction and tread pattern. If replacing only two would cause a significant difference in the rolling circumference, then all four should be replaced. In all other cases, the tyres must be replaced as an axle pair and must be fitted at the rear as per UK safety guidance.
