The 2023 Audi Trucks SQ8 sits in the modern high-performance luxury SUV class, where sharp road manners, substantial curb presence, and everyday usability all have to work together. That balance makes tire selection especially important, because the SQ8 depends on a wide, low-profile radial setup to support both appearance and drivability. This model uses either 285/40R22 or 285/45R21 radial tires, so the first step is confirming which wheel diameter is actually on the vehicle. Once that is settled, the decision shifts to choosing the right fitment for your exact setup, especially if the SUV has alternate wheels or suspension changes.
Which Tire Size Is Right for The 2023 Audi Trucks SQ8
The 2023 Audi Trucks SQ8 uses two primary tire sizes, and the difference comes down to wheel diameter rather than sub-model trim alone. Both Premium Plus and Prestige can use 285/40R22 or 285/45R21 radial tires, so confirming whether the vehicle has 21-inch or 22-inch wheels is the first step before comparing tire choices.
The 285/40R22 size is a metric radial format: 285 identifies the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 22 is the wheel diameter in inches. On the 2023 Audi Trucks SQ8, this size supports the larger wheel fitment used on some vehicles in this model range. Its low-profile layout is part of the overall look and stance, so replacement selection should start with confirming the existing 22-inch wheel setup and then checking clearance, load suitability, and the condition of any modified suspension components.
The 285/45R21 size follows the same metric radial naming system, with a 285-millimeter nominal section width, a 45-series profile, radial construction, and a 21-inch wheel diameter. For the 2023 Audi Trucks SQ8, this is the alternate primary fitment tied to a 21-inch wheel package rather than a different basic tire type. Because the overall dimensions are close to the 22-inch option but the wheel diameter is different, this size should be chosen only after verifying the actual wheels on the vehicle and checking that any wheel or brake changes have not altered fitment needs.
Tire fitment for the 2023 Audi Trucks SQ8 is straightforward in one sense: both covered sub-models use the same two primary size choices. What matters most is not Premium Plus versus Prestige, but whether the SUV is currently fitted with 21-inch or 22-inch wheels.

2023 Audi Trucks SQ8 Premium Plus
The 2023 Audi Trucks SQ8 Premium Plus can use either of the two primary radial tire sizes associated with this model. Tire selection starts with confirming the wheel diameter on the vehicle, then matching the replacement tire to that setup rather than assuming one size belongs to every Premium Plus.
The 2023 Audi Trucks SQ8 Prestige also uses the same pair of primary radial tire sizes found across the model range. That means the practical decision is wheel-based, so checking for 21-inch or 22-inch wheels is more important than trim name when selecting replacement tires.
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
SQ8 owners usually need to sort out wheel diameter first, then compare tire size meaning, radial fitment, and the effect of wheel or suspension changes. These FAQs focus on the exact 2023 Audi Trucks SQ8 and the two primary tire sizes it uses.
Tire Size & Fitment
What tire size fits a 2023 Audi Trucks SQ8?
The 2023 Audi Trucks SQ8 uses either 285/40R22 or 285/45R21 tires, and both are radial sizes. These are the two primary fitments for this exact year and model, with the difference tied to wheel diameter rather than a separate bias-ply versus radial decision.
The key step is matching the tire size to the wheels currently on the SUV. A 22-inch wheel requires 285/40R22, while a 21-inch wheel requires 285/45R21, so checking the wheel itself and the existing tire sidewall is the safest place to start before choosing a replacement.
What size rim does a 2023 Audi Trucks SQ8 use?
The 2023 Audi Trucks SQ8 uses either a 21-inch or 22-inch rim, depending on which of its two primary tire sizes is on the vehicle. The 285/45R21 tire is built for a 21-inch wheel, and the 285/40R22 tire is built for a 22-inch wheel.
Rim diameter has to match the tire exactly, so this is not a detail to estimate. Looking at the current tire sidewall or measuring the installed wheel size will confirm which setup the SUV has, which is especially important if the vehicle has been changed from its original wheel package.
Do all 2023 Audi Trucks SQ8 sub-models use the same tire size?
Both the 2023 Audi Trucks SQ8 Premium Plus and Prestige use the same two primary tire sizes: 285/40R22 and 285/45R21. That means trim level alone does not narrow the fitment to one size, since either sub-model can appear with either wheel-and-tire combination.
Because the sub-models share the same size options, the actual wheel diameter on the vehicle matters more than the trim badge. Checking for 21-inch or 22-inch wheels will answer the fitment question faster than relying on model name alone, particularly on a used SQ8 or one with wheel changes.
Choosing the Right Tire
What should I consider when choosing a 285/40R22 tire for a 2023 Audi Trucks SQ8?
Start by confirming that the SQ8 actually has 22-inch wheels and that 285/40R22 is the size currently required. This size uses a wide section and a low-profile metric radial format, so the tire choice needs to match the wheel diameter exactly and suit the vehicle's intended road use.
Beyond the size itself, compare the overall condition of the wheel setup and any changes that may affect clearance. An SQ8 with aftermarket wheels, brake changes, or altered ride height can need closer fitment review, even when the tire size on paper matches the original 22-inch specification.
What should I consider when choosing a 285/45R21 tire for a 2023 Audi Trucks SQ8?
The first consideration is simple but essential: make sure the vehicle is running 21-inch wheels, since 285/45R21 is only correct for that rim diameter. This size keeps the same 285-millimeter nominal width as the 22-inch option, but it is built around a different wheel package.
Once the wheel diameter is confirmed, review the vehicle as it sits today rather than assuming every SQ8 is unchanged. Tire replacement is more straightforward on a stock setup, while aftermarket wheels, alignment changes, or suspension modifications can affect clearance and should be checked before mounting new tires.
How do I choose between the available tire sizes for a 2023 Audi Trucks SQ8?
The choice is not between two interchangeable sizes, but between the size that matches the wheels already on the SUV. A 2023 Audi Trucks SQ8 with 22-inch wheels uses 285/40R22, while one with 21-inch wheels uses 285/45R21, and both are primary radial fitments for this model.
That makes wheel confirmation the real decision point. Once the wheel diameter is verified, the remaining evaluation centers on proper fitment for the current setup, including any non-stock wheel, brake, or suspension changes that could influence clearance or the way the tire sits on the vehicle.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Audi Trucks SQ8 restoration?
Correct tire fitment still matters, even on a modern high-performance SUV such as the 2023 Audi Trucks SQ8. The vehicle uses specific low-profile radial sizes tied to either 21-inch or 22-inch wheels, and staying with the proper size helps preserve the intended stance, wheel relationship, and overall presentation.
Appearance on a newer collector vehicle is often shaped as much by proportion as by brand or tread style. Anyone aiming for an accurate, well-kept look should verify the actual wheel package on the vehicle and avoid assuming that either SQ8 size will suit every example without checking the installed setup.
How does tire construction affect the appearance of a restored 2023 Audi Trucks SQ8?
On the 2023 Audi Trucks SQ8, tire construction is straightforward because the primary fitments are radial. That means the visual difference usually comes less from bias-ply versus radial choice and more from selecting the correct modern size for the wheel diameter already on the vehicle.
Using the proper 285/40R22 or 285/45R21 size helps maintain the SUV's intended profile and avoids a mismatched look between tire and wheel. For a carefully presented SQ8, confirming the wheel package and avoiding improvised substitutions is usually more important than chasing appearance through an incorrect size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi Trucks SQ8?
Yes, modifications can affect tire fitment on a 2023 Audi Trucks SQ8 even when the tire size itself matches one of the original specifications. Wheel width, offset changes, suspension lowering, brake upgrades, and body alterations can all change how a 285/40R22 or 285/45R21 tire sits and clears.
That is why a modified SQ8 should be checked as it currently exists, not simply by model-year fitment alone. Inspecting steering clearance, fender clearance, and the relationship between tire and suspension components can prevent rubbing or mounting issues that may not appear on a stock vehicle.
What should I inspect before driving a 2023 Audi Trucks SQ8 on new tires?
Before road use, inspect the installed tire size against the wheel diameter, confirm proper inflation, and look over the wheels for damage or irregular seating. It is also worth checking alignment-related wear on the previous tires, since uneven wear can point to suspension or setup issues that new tires will not correct.
A quick clearance check at full steering lock is also useful, especially on an SQ8 with larger wheels or any aftermarket changes. After the first miles, recheck pressure and visually inspect the tires again so any rubbing, air loss, or mounting concern can be caught early.
How often should tires on a 2023 Audi Trucks SQ8 be inspected?
Tires on a 2023 Audi Trucks SQ8 should be inspected regularly, not just when tread looks low. Frequent checks for pressure loss, cuts, bulges, irregular wear, and impact damage are especially important on a performance-oriented SUV that uses wide, low-profile radial tires.
A monthly visual inspection is a sensible routine, with an extra check before longer trips or after striking potholes or road debris. Vehicles that sit for periods should also have their tires reviewed for flat spotting or age-related deterioration, since low annual mileage does not eliminate the need for tire care.
