The 2022 Audi Trucks Q8 sits in the modern luxury SUV space with a strong emphasis on bold styling, large-diameter wheels, and a road-focused performance character. For many owners, tire selection is less about vintage-style restoration and more about preserving the Q8’s intended stance, handling balance, and ride quality. This model uses radial tires in two fitments, 285/45R21 and 285/40R22, depending on sub-model and wheel package. That makes wheel diameter the first thing to confirm before comparing tire choices. Once the correct size is established, the decision centers on matching the tire to the vehicle’s wheel setup, driving use, and overall presentation.
Which Tire Size Is Right for The 2022 Audi Trucks Q8
The 2022 Audi Trucks Q8 uses two primary tire sizes, and the difference comes down to sub-model configuration and wheel diameter. Both fitments are radial, but one is built for a 21-inch wheel and the other for a 22-inch wheel, so confirming the actual wheel diameter on the vehicle is the first step before selecting a tire.
285/45R21 is a modern metric radial size in which 285 indicates nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 21 is the rim diameter in inches. On the 2022 Audi Trucks Q8, this fitment suits a 21-inch wheel and keeps the sizing in the modern SUV performance-touring range. Its dimensions make it a distinct fitment rather than a substitute for the 22-inch option. This is the size to evaluate when the vehicle is equipped with 21-inch wheels and the goal is to stay with the correct wheel-based fitment.
285/40R22 follows the same modern metric radial format, with a 285-millimeter nominal section width, a 40-series profile, radial construction, and a 22-inch rim diameter. For the 2022 Audi Trucks Q8, this size is tied to the larger wheel setup and carries a slightly lower-profile appearance than the 21-inch fitment. Even though the section width matches the 285/45R21 size, the wheel diameter is different and needs to be confirmed before purchase. This is the fitment to focus on when the Q8 is riding on 22-inch wheels.
Tire fitment on the 2022 Audi Trucks Q8 varies by sub-model and wheel setup rather than following one universal size across the lineup. Checking the exact trim matters because some versions use only the 21-inch fitment, while others may use either the 21-inch or 22-inch size.

2022 Audi Trucks Q8 Premium
The 2022 Audi Trucks Q8 Premium uses the 285/45R21 radial tire size. Tire selection for this sub-model starts with maintaining the 21-inch wheel fitment and then choosing a tire that matches the vehicle’s intended road use and wheel setup.
The 2022 Audi Trucks Q8 Premium Plus can use either 285/45R21 or 285/40R22, depending on how the vehicle is equipped. The key step here is confirming the actual wheel diameter on the SUV before comparing tires, since the two sizes are tied to different rims.
The 2022 Audi Trucks Q8 Prestige also appears with either 285/45R21 or 285/40R22 radial tires. That means the wheel package needs to be verified first, after which tire selection becomes a matter of staying with the proper size for the 21-inch or 22-inch setup.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Tire questions for the 2022 Audi Trucks Q8 usually come down to identifying the correct size, confirming 21-inch versus 22-inch wheel fitment, and understanding how trim level affects the selection. The answers below focus on practical fitment, tire choice, and road-use checks for this exact model.
Tire Size & Fitment
What tire size fits a 2022 Audi Trucks Q8?
The 2022 Audi Trucks Q8 uses two tire sizes: 285/45R21 and 285/40R22. Both are radial fitments, but they are not used interchangeably across one wheel size because each tire is built for a different rim diameter.
Choosing between them starts with confirming the wheel size actually on the vehicle. A Q8 Premium uses 285/45R21, while Premium Plus and Prestige models may use either size depending on wheel package, so checking the trim and the installed wheels is the safest way to narrow the fitment.
What size rim does a 2022 Audi Trucks Q8 use?
The 2022 Audi Trucks Q8 uses either a 21-inch or 22-inch rim, depending on the tire fitment. The 285/45R21 tire is built for a 21-inch wheel, while the 285/40R22 tire is built for a 22-inch wheel.
That makes rim diameter the first item to verify before replacing tires. Looking only at tread width can be misleading because both sizes share a 285-millimeter nominal width, yet they mount on different wheel diameters and should be matched to the actual wheel installed on the SUV.
Do all 2022 Audi Trucks Q8 sub-models use the same tire size?
No, the 2022 Audi Trucks Q8 sub-models do not all use the same tire size. Premium uses 285/45R21, while Premium Plus and Prestige can use either 285/45R21 or 285/40R22 depending on the wheel setup.
That variation means trim name alone is not always enough to choose a tire, especially on Premium Plus and Prestige models. Checking the sidewall of the current tire or confirming the wheel diameter on the vehicle will prevent ordering a 21-inch tire for a 22-inch wheel, or the reverse.
Choosing the Right Tire
What should I consider when choosing a 285/45R21 tire for a 2022 Audi Trucks Q8?
A 285/45R21 tire for a 2022 Audi Trucks Q8 should first match the vehicle’s 21-inch wheel setup. Beyond size, the main considerations are staying with the correct radial construction and choosing a tire suited to how the SUV is driven, whether that means daily road use, long-distance touring, or a more appearance-focused replacement.
Wheel condition, suspension condition, and the vehicle’s actual use all matter when selecting within the size. It also helps to inspect the current tires for uneven wear, since that can point to alignment or inflation issues that should be corrected before installing a new set.
What should I consider when choosing a 285/40R22 tire for a 2022 Audi Trucks Q8?
Choosing a 285/40R22 tire for a 2022 Audi Trucks Q8 starts with confirming that the vehicle has the 22-inch wheel package. This size keeps the correct radial format for that setup and is the right starting point when the SUV is equipped with the larger-diameter factory-style wheel fitment.
Because this is a lower-profile tire than the 21-inch alternative, buyers should pay close attention to wheel condition, curb damage, and any signs of uneven wear on the outgoing tires. It is also wise to confirm that no aftermarket wheel changes have altered the original fitment assumptions.
How do I choose between the available tire sizes for a 2022 Audi Trucks Q8?
The right way to choose between the available tire sizes for a 2022 Audi Trucks Q8 is to match the tire to the wheel diameter already on the vehicle. A 21-inch wheel takes 285/45R21, while a 22-inch wheel takes 285/40R22, and both sizes are intended as distinct radial fitments.
Once the wheel size is confirmed, the next step is looking at the exact sub-model and checking whether the SUV remains in its original wheel configuration. Premium Plus and Prestige models can appear with either setup, so visual wheel inspection is just as important as reading the trim badge.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Audi Trucks Q8?
Yes, modifications can affect tire fitment on a 2022 Audi Trucks Q8. Aftermarket wheels, suspension changes, lowering, spacer use, or body alterations can all change the space available around the tire and may also alter which wheel diameter or tire profile is appropriate.
Even when the sidewall shows one of the original Q8 sizes, the full setup still deserves a clearance check at steering lock and under suspension movement. Tire replacement goes more smoothly when wheel width, offset, and any non-stock hardware are reviewed before the next set is chosen.
What should I inspect before driving a 2022 Audi Trucks Q8 on new tires?
Before driving a 2022 Audi Trucks Q8 on new tires, inspect inflation pressure, wheel condition, lug hardware, and basic suspension condition. It is also worth checking that the installed tire size matches the wheel diameter, since this model uses both 21-inch and 22-inch fitments.
A short inspection for rubbing, sidewall contact, or unusual clearance issues is especially useful if the SUV has had wheel or suspension changes. After the first miles, rechecking pressure and watching for vibration or uneven wear can help catch alignment or installation issues early.
What should I check before a longer drive in a 2022 Audi Trucks Q8?
Before a longer drive in a 2022 Audi Trucks Q8, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. Since this model may use either 285/45R21 or 285/40R22, it is also smart to confirm that all four tires are the correct size for the wheels on the vehicle.
Longer trips put more emphasis on basic maintenance details that are easy to overlook on a daily-driven SUV. Looking for uneven tread wear, slow air loss, or signs of impact damage can help prevent trouble on the road and may also reveal alignment or wheel-condition issues worth addressing first.
