Audi Q6 e-tron tires
The Audi Q6 e-tron leaves the factory on 235/60 R19 and 235/65 R18 and 255/45 R21 and 255/50 R20 depending on wheel size, and the 235/65 R18 110H XL below is the one most owners are replacing. XL is not optional here; it is what the car was type approved on. It is staggered: a 235 section at the front and a 255 at the back, so the two can never be swapped across axles and the rear goes first. The Jaguar I-Pace takes the same size.

Your own placard is the authority. You will find it on the on the driver's door jamb, on the B-pillar. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tire.
What changes on this car
Audi USA's 2027 specification lists the SQ6's standard 20in set as all-season run-flat tires, offered as an option on the Q6. A non-run-flat tire in the same size fits the rim but behaves differently after a puncture, so check the sidewall before ordering.
All four wheel sizes are staggered and XL. The 18in and 20in rears share the highest rating, load index 112 or 1,120 kg per tire; the 21in rear drops to 109.
The 18in set, listed for UK cars and the US Ultra package, has the deepest sidewall at roughly 153 mm on the front. The 21in front has about 115 mm and moves to a W speed rating where every smaller size is H.
The Q6 is built on the PPE platform it shares with the electric Porsche Macan. Audi USA quotes 5,236 lb for the 2027 Q6 and 5,390 lb for the SQ6.
No tires listed against this fitment yet. Product specifications are published from each manufacturer's own data and that work is not finished for 235/65 R18. Match or exceed every figure in the table above and you cannot go far wrong.

Including the manufacturer's own published figure. Neither source is standing next to your vehicle, which is why the placard still wins.

Common questions
- What size tires does the Audi Q6 e-tron take?
- It runs 235/60 R19 and 235/65 R18 and 255/45 R21 and 255/50 R20. The exact fitment for your car is on On the driver's door jamb, on the B-pillar.
- Can I fit a cheaper tire to a Audi Q6 e-tron?
- Only at 235/65 R18 110H XL or better. That is the figure to hold: a tire below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
