Audi SQ8 4M — Wheel Fitment & Specs
Overview
The Audi Q8 is a mid-size luxury crossover SUV made by Audi that was launched in 2018. It is the flagship of the Audi SUV line, and is being produced at the Volkswagen Bratislava Plant in Slovakia. The Q8 shares its platform with the Audi Q7 and Lamborghini Urus among others within the Volkswagen Group's product lineup. Compared to the Q7, it is slightly shorter but wider, featuring a sloped roofline that results in less cargo space and no third-row seating option. It features full-laser headlamps and taillamps, an interior with three touch screens including an enlarged virtual cockpit, and advanced driver assistance systems.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 8.5J–10.5J | ET0–ET25 |
As a rule, each extra 1J of width wants roughly +8–10 ET to keep the wheel tucked. The exact offset and any spacer are confirmed by the fit-check.
UK popularity & demand
