The 2023 Audi Trucks RS Q8 sits in the modern high-performance luxury SUV category, blending aggressive road presence with the kind of speed and braking capability that make tire choice more than a cosmetic decision. On this exact model, fitment centers on two radial sizes, 295/40R22 and 295/35R23, with the ceramic brake package tied specifically to the 23-inch setup. That means the real question is not simply which tire looks right, but which wheel and brake configuration the vehicle has before any replacement is chosen. For an RS Q8 used on the street, on longer highway runs, or kept carefully as a premium enthusiast vehicle, correct size confirmation comes first.
Which Tire Size Is Right for The 2023 Audi Trucks RS Q8
The 2023 Audi Trucks RS Q8 uses two primary tire sizes, and the difference is tied to wheel diameter rather than a change in basic tire construction. Both sizes are radial, but one fits a 22-inch wheel and the other fits a 23-inch wheel, so the first step is confirming the exact wheel and brake setup on the vehicle. That matters especially on models equipped with the ceramic brake package, which uses the 23-inch fitment.
295/35R23 is a modern metric radial size in which 295 refers to nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 23 is the wheel diameter in inches. On the 2023 Audi Trucks RS Q8, this size belongs to the larger-wheel fitment and is also the size used on the ceramic brake package configuration. Its dimensions keep it very close in overall height to the 22-inch alternative, so the decision is driven more by wheel and brake hardware than appearance alone. Confirming the actual wheel diameter before replacement is essential.
295/40R22 is also a modern metric radial size, with the same 295-millimeter nominal width but a 40-series profile mounted on a 22-inch wheel. For the 2023 Audi Trucks RS Q8, this size serves vehicles using the 22-inch wheel setup rather than the 23-inch arrangement. Its overall diameter remains very close to the 23-inch fitment, but that does not make the two sizes interchangeable without the matching wheel. This is the size to evaluate when the vehicle is equipped with 22-inch wheels and does not require the 23-inch ceramic-brake fitment.
RS Q8 sub-model fitment is mostly straightforward, but one configuration changes the decision. The standard speed-rated variants can use either 22-inch or 23-inch radial fitments, while the ceramic brake package is tied to the 23-inch size, making wheel and brake confirmation especially important.

This RS Q8 configuration uses the same two radial fitments found across the broader model range, so selection starts with confirming whether the vehicle is on 22-inch or 23-inch wheels. Once that is established, the focus shifts to replacing the tire in the exact mounted size and checking overall wheel condition before road use.
This version also carries the two-size fitment pattern, with both 295/40R22 and 295/35R23 used depending on wheel setup. The practical takeaway is to verify the current wheel diameter on the vehicle rather than choosing by speed designation alone.

Frequently Asked Questions
RS Q8 owners usually need to sort out wheel diameter first, then confirm how that choice relates to sub-model fitment, brake package requirements, and safe road-use checks. These answers focus on exact size selection, rim fitment, maintenance, and practical replacement decisions for this 2023 model.
Tire Size & Fitment
What tire size fits a 2023 Audi Trucks RS Q8?
The 2023 Audi Trucks RS Q8 uses two radial tire sizes: 295/40R22 and 295/35R23. Both are primary fitments for this model, but they correspond to different wheel diameters, so the correct size depends on the exact wheel setup on the vehicle.
That means the first thing to check is whether the RS Q8 currently has 22-inch or 23-inch wheels. The ceramic brake package uses 295/35R23, while other RS Q8 configurations may use either size. Looking only at overall tire width is not enough, because the mounted wheel diameter determines which tire can actually be used.
What size rim does a 2023 Audi Trucks RS Q8 use?
A 2023 Audi Trucks RS Q8 uses either a 22-inch or 23-inch rim, depending on configuration. The 295/40R22 tire mounts on a 22-inch wheel, while the 295/35R23 tire mounts on a 23-inch wheel.
Wheel diameter needs to be confirmed before any tire replacement is selected, because a 22-inch tire and a 23-inch tire cannot be mixed onto the same rim. On an RS Q8, that check is especially important if the vehicle has been optioned differently from another example or if the current wheels were changed after delivery.
Do all 2023 Audi Trucks RS Q8 sub-models use the same tire size?
No. The 2023 Audi Trucks RS Q8 appears with more than one fitment pattern across its sub-models. The 155 mph and 174 mph versions can use both 295/40R22 and 295/35R23, while the RS Q8 with Ceramic Brake Pkg. uses 295/35R23.
That makes the sub-model and hardware setup worth checking before replacement. A speed-designated RS Q8 may still be on either wheel diameter, but the ceramic brake package narrows the choice to the 23-inch tire. Matching the tire to the actual wheel and brake configuration is more important than relying on model name alone.
Choosing the Right Tire
What should I consider when choosing a tire for a 2023 Audi Trucks RS Q8?
Start with the exact tire size already required by the vehicle: either 295/40R22 or 295/35R23. Both are radial fitments, so the key decision is not switching construction type, but selecting the tire that matches the wheel diameter and the specific RS Q8 configuration.
After size is confirmed, inspect the wheel itself, check that the tires on the vehicle match front to rear where appropriate, and pay attention to any brake-package limitations. An RS Q8 used for regular road driving should also have its replacement tires checked for proper load capability, overall condition, and enough clearance within the existing wheel and suspension setup.
How do I choose between 295/40R22 and 295/35R23 for a 2023 Audi Trucks RS Q8?
The choice is determined by wheel diameter. A 2023 Audi Trucks RS Q8 with 22-inch wheels uses 295/40R22, while one with 23-inch wheels uses 295/35R23. The ceramic brake package is tied to the 23-inch fitment.
Even though the two sizes are close in overall diameter, they are not interchangeable without the matching wheel. Looking at the sidewall marking on the current tire and verifying the wheel size directly is the safest way to avoid ordering the wrong fitment. On a used RS Q8, that matters even more if wheels were changed by a previous owner.
What rim-fitment details matter when choosing 2023 Audi Trucks RS Q8 tires?
The most important rim-fitment detail is diameter: 22 inches for 295/40R22 and 23 inches for 295/35R23. That single measurement determines which tire size can physically mount to the wheel on a 2023 Audi Trucks RS Q8.
It also helps to inspect the wheel for damage, confirm that the wheel and tire combination clears the brake hardware, and make sure the vehicle has a consistent setup at all four corners if that is how it is being serviced. Any aftermarket wheel change should be checked carefully before assuming the same replacement size still applies.
Restoration & Appearance
Does correct tire fitment matter for a 2023 Audi Trucks RS Q8?
Yes. On a 2023 Audi Trucks RS Q8, correct tire fitment is fundamental because the vehicle uses high-performance modern radial sizes tied directly to 22-inch or 23-inch wheels. Selecting the wrong diameter means the tire will not match the wheel, regardless of how close the width appears.
Fitment also affects the vehicle's overall presentation and how properly the wheel-and-tire package fills the arches. On a premium modern enthusiast SUV like the RS Q8, maintaining the intended size relationship helps preserve a clean, cohesive look while avoiding unnecessary complications with wheel, brake, and clearance compatibility.
How does tire size affect the appearance of a 2023 Audi Trucks RS Q8?
The 2023 Audi Trucks RS Q8 uses two low-profile modern radial sizes that create different visual proportions because one is built around a 22-inch wheel and the other around a 23-inch wheel. Even with similar overall diameter, the sidewall-to-wheel relationship changes the look.
That makes it worth matching the replacement tire exactly to the wheel setup already on the vehicle. A correct-size replacement keeps the RS Q8's stance and wheel presentation consistent, while an incorrect diameter immediately creates a fitment problem. Appearance is part of the decision, but it should follow proper wheel-size confirmation rather than lead it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi Trucks RS Q8?
Yes. A 2023 Audi Trucks RS Q8 can be affected by wheel changes, suspension alterations, or brake-related modifications that shift the original fitment assumptions. Even when the factory sizes are 295/40R22 and 295/35R23, an aftermarket setup may change what is currently mounted on the vehicle.
That is why the actual wheel diameter and tire sidewall marking should be checked before replacing anything. Lowering changes, wheel offset differences, and non-original wheels can all influence clearance around the fenders, suspension, and brake components. A modified RS Q8 should always be inspected as it sits, not as a stock example.
What should I inspect before driving a 2023 Audi Trucks RS Q8 on new tires?
Before driving, confirm that the new tires match the wheel diameter, are seated properly on the rims, and are inflated correctly for the application. A quick inspection should also cover valve stems, wheel condition, and any visible interference around brakes or suspension components.
It also helps to recheck the sidewalls and tread after the first few miles for any sign of rubbing, unusual air loss, or mounting issues. On a high-performance SUV such as the RS Q8, taking a moment to verify basic fitment and condition before full road use helps prevent avoidable problems and confirms that the replacement was done correctly.
What should I check before a longer drive in a 2023 Audi Trucks RS Q8?
Before a longer drive, inspect all four tires for proper inflation, tread condition, cuts, bulges, and any signs of irregular wear. On a 2023 Audi Trucks RS Q8, it is also smart to confirm that the vehicle is riding on the correct 22-inch or 23-inch tire size at each corner.
A longer trip is a good time to look closely at wheel condition and make sure there is no rubbing or air loss developing from daily use. Vehicles with recent tire replacement, wheel changes, or performance brake hardware deserve an especially careful walkaround so small fitment or condition issues do not turn into road-trip problems.
