The Audi Q8 is Audi's flagship large luxury SUV-coupe — a stylistically bold alternative to the BMW X6 and Mercedes GLE Coupe. It uses Quattro AWD standard and shares its MLB Evo platform with the Lamborghini Urus and Porsche Cayenne. The Q8 sits on large wheels from 20 to 23 inches depending on trim, with the RS Q8 representing the performance pinnacle at 295/35R23.
Q8 Tire Sizes by Trim
Audi Q8 45 TFSI (base): 275/50R20 on standard 20-inch wheels, or 285/45R21 on optional 21-inch. Both are square setups allowing full rotation. The 20-inch standard is a conservative all-season touring fitment.
Audi Q8 55 TFSI: typically 285/45R21 standard on 21-inch wheels, or 285/40R22 on 22-inch optional. The 21-inch is the most common fitment on production Q8s and has good aftermarket availability.
SQ8 TFSI: 285/45R21 standard, or 285/40R22 on 22-inch wheels — square, rotatable. The SQ8 represents the performance sweet spot before the RS trim.
RS Q8: 295/40R22 standard, or 295/35R23 on 23-inch wheels — square, not staggered — this is still an extreme performance fitment with very limited aftermarket tire options. Pirelli P Zero and Michelin Pilot Sport are the primary choices, and availability in 295/35R23 is limited. Owners of the RS Q8 should check availability carefully before their tires expire.
Best Replacement Tires for Q8 45 and Q8 55
For the 275/50R20 common Q8 fitment: the Michelin CrossClimate 2 is an excellent all-weather choice with 3PMSF winter certification. For pure performance, the Michelin Pilot Sport A/S 4 in 275/50R20 delivers UHP all-season grip appropriate for the Q8 platform.
The Continental PremiumContact 6 is a strong touring choice for Q8 owners who prioritize smooth ride and low noise over handling limits. The Q8 is a grand touring SUV at heart — many owners will prefer comfort-oriented rubber.
For the 285/45R21 fitment: same Michelin Pilot Sport A/S 4 recommendation for the primary choice. The Pirelli P Zero All Season Plus is another option that leans into the sporty character of the Q8 design.

Best Performance Tires for the SQ8
The SQ8 on 285/40R22 benefits from performance-tier rubber given its 500-hp output. The Michelin Pilot Sport 4S in 285/40R22 is the first choice — available in this size and offers noticeably better grip than all-season alternatives.
The Continental SportContact 7 in 285/40R22 is the strong alternative — slightly less expensive than the PS4S with competitive performance characteristics.
For SQ8 owners in Georgia who want year-round capability: the Pirelli P Zero All Season Plus (Elect) or Michelin Pilot Sport A/S 4 in 285/40R22 allow year-round use without compromising the SQ8's performance character significantly.
