The 2026 Audi Trucks RS Q8 sits at the sharp end of the modern high-performance SUV market, blending Audi’s coupe-like utility format with the pace and road presence expected from an RS model. For owners, tire selection is less about vintage-style restoration and more about confirming the exact wheel setup already on the vehicle. This RS Q8 uses radial fitments in either 295/35R23 or 295/40R22, both wide, low-profile metric sizes tied to different rim diameters. The real choice starts with identifying whether the vehicle wears 22-inch or 23-inch wheels. From there, the focus shifts to correct sizing, wheel compatibility, and maintaining proper clearance and handling character.
Which Tire Size Is Right for The 2026 Audi Trucks RS Q8
The 2026 Audi Trucks RS Q8 uses two primary tire sizes, and the first step is confirming wheel diameter. Both sizes are radial metric fitments, but one is built for a 23-inch rim and the other for a 22-inch rim. Because the covered RS Q8 sub-models share both sizes, the real fitment question is which wheel package is on the vehicle before comparing tire options.
A 295/35R23 tire uses a 295-millimeter section width, a 35-series aspect ratio, radial construction, and a 23-inch rim diameter. On the 2026 Audi Trucks RS Q8, this is one of the two primary high-performance fitments and is tied specifically to a 23-inch wheel. Its wide section and short sidewall reflect the vehicle’s performance-oriented setup rather than a tall touring-style profile. This size makes sense when the RS Q8 is already equipped with 23-inch wheels and the goal is to retain the intended wheel diameter, overall stance, and low-profile appearance.
A 295/40R22 tire keeps the same 295-millimeter section width but uses a 40-series aspect ratio on a 22-inch rim. For the 2026 Audi Trucks RS Q8, it serves as the alternate primary fitment for vehicles running a 22-inch wheel package. Compared with the 23-inch size format, the key difference is not width but rim diameter and sidewall profile. This size should be evaluated when the vehicle is fitted with 22-inch wheels and the owner wants to stay with the proper rim size rather than forcing a tire onto the wrong wheel diameter.
Fitment is straightforward across the covered 2026 Audi Trucks RS Q8 sub-models because each one uses the same two primary tire sizes. The important step is not trim identification so much as confirming whether the vehicle is on 22-inch or 23-inch wheels before choosing tires.

2026 Audi Trucks RS Q8 (155 mph)
The 2026 Audi Trucks RS Q8 (155 mph) uses the same two radial tire sizes found across the other covered RS Q8 versions. Tire selection comes down to confirming the wheel diameter on the vehicle first, then matching the correct metric size to that setup.
The 2026 Audi Trucks RS Q8 (174 mph) follows the same fitment pattern, with both primary radial sizes applicable depending on wheel package. That means the buyer should verify whether the vehicle carries 22-inch or 23-inch wheels before comparing replacement tires.
The 2026 Audi Trucks RS Q8 (190 mph) also shares the same pair of primary radial fitments. The practical tire decision is tied to the actual wheel diameter on the vehicle, since both sizes belong to different rims rather than different body or trim distinctions.
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
These FAQs focus on the two tire sizes used on the 2026 Audi Trucks RS Q8, how to confirm the correct rim diameter, and what to check before replacing tires on a high-performance SUV with wide, low-profile radial fitments.
Tire Size & Fitment
What tire size fits a 2026 Audi Trucks RS Q8?
The 2026 Audi Trucks RS Q8 uses two primary tire sizes: 295/35R23 and 295/40R22. Both are radial metric sizes, and each belongs to a different wheel diameter rather than a different basic vehicle family.
The practical choice is determined by the wheels on the vehicle. A 295/35R23 tire belongs on a 23-inch rim, while a 295/40R22 tire belongs on a 22-inch rim. Before replacing tires, check the actual wheel size already installed and make sure any previous owner changes have not altered the original wheel and tire package.
What size rim does a 2026 Audi Trucks RS Q8 use?
A 2026 Audi Trucks RS Q8 can use either a 23-inch rim with 295/35R23 tires or a 22-inch rim with 295/40R22 tires. Both rim diameters are part of the vehicle’s primary tire fitment range.
That makes wheel confirmation the first step before ordering tires. The tire size and rim diameter must match exactly, so a 23-inch tire cannot be mounted on a 22-inch wheel, and the reverse is also true. It is also wise to confirm the wheel markings directly if the RS Q8 has aftermarket wheels or a wheel-and-tire package added after delivery.
Do all 2026 Audi Trucks RS Q8 sub-models use the same tire size?
The covered 2026 Audi Trucks RS Q8 sub-models all use the same two tire sizes: 295/35R23 and 295/40R22. That includes the 155 mph, 174 mph, and 190 mph versions.
Because the sub-models share both sizes, the more important check is the actual wheel setup on the vehicle in front of you. An RS Q8 wearing 22-inch wheels should stay with the corresponding 22-inch tire size, while one on 23-inch wheels needs the matching 23-inch fitment. Always confirm the current wheel diameter before moving ahead with a replacement tire.
Choosing the Right Tire
What should I consider when choosing a 295/35R23 tire for a 2026 Audi Trucks RS Q8?
A 295/35R23 tire should be chosen only for a 2026 Audi Trucks RS Q8 equipped with 23-inch wheels. The size combines a wide 295-millimeter section with a short 35-series profile, so staying with the correct rim diameter is the first requirement.
After wheel size is confirmed, compare the tire’s overall suitability for a performance SUV application. Clearance, load capability, and the condition of the suspension and alignment all matter when replacing a wide, low-profile tire. It also helps to verify that all four tires match in size and construction unless the vehicle is intentionally set up otherwise.
What should I consider when choosing a 295/40R22 tire for a 2026 Audi Trucks RS Q8?
A 295/40R22 tire is appropriate for a 2026 Audi Trucks RS Q8 that runs a 22-inch wheel package. It uses the same 295-millimeter width as the 23-inch option, but its profile and rim diameter are specific to a 22-inch setup.
The key is to confirm that the vehicle has not been changed to a different wheel diameter since new. Once that is settled, check for proper clearance at full steering lock, especially if the SUV has aftermarket wheels, suspension changes, or replacement components that alter ride height. Correct sizing and consistent fitment across the vehicle are more important than choosing by appearance alone.
How do I choose between the available tire sizes for a 2026 Audi Trucks RS Q8?
The choice between 295/35R23 and 295/40R22 is not a matter of preference alone. On a 2026 Audi Trucks RS Q8, each size belongs to a different wheel diameter, so the correct tire is determined by whether the vehicle has 23-inch or 22-inch rims.
Start by checking the wheel itself rather than guessing from the sidewall currently installed, especially if the vehicle has changed hands or been modified. Once rim diameter is confirmed, stay with the matching tire size and construction. That approach helps preserve proper mounting, clearance, and the overall tire-to-wheel relationship intended for the vehicle’s setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2026 Audi Trucks RS Q8?
Yes, modifications can affect tire fitment on a 2026 Audi Trucks RS Q8 even when the tire size appears correct on paper. Changes to wheels, offsets, suspension height, alignment, or body clearance can all alter how a 295/35R23 or 295/40R22 tire sits and moves on the vehicle.
A lowered SUV, wider aftermarket wheel, or altered suspension setting can create rubbing issues that would not exist on a stock setup. Checking clearance at the fender, inner liner, and steering range is a smart step before road use. Verifying the actual wheel dimensions matters just as much as confirming the size printed on the tire sidewall.
What should I inspect before driving a 2026 Audi Trucks RS Q8 on new tires?
Before driving a 2026 Audi Trucks RS Q8 on new tires, inspect wheel condition, mounting accuracy, inflation pressure, and the overall condition of the suspension and alignment. It is also important to confirm that the tire size matches the wheel diameter exactly.
A final walkaround should include checking for sidewall damage, uneven gaps, and any sign of contact at the fender or inner wheel area. Wide, low-profile tires can react quickly to alignment or wheel issues, so attention to steering feel and vibration during the first miles is worthwhile. Rechecking pressure after installation is also a sensible part of the process.
What should I check before a longer drive in a 2026 Audi Trucks RS Q8?
Before a longer drive, the 2026 Audi Trucks RS Q8 should have all tires inspected for proper pressure, visible cuts, bulges, cracking, and uneven wear. Confirming that all four tires are the correct size for the installed wheels is part of that same check.
Longer trips put more heat and sustained load into a high-performance SUV tire, so small issues are easier to catch in the garage than on the road. Looking over tread condition and checking for slow air loss can prevent problems later. It is also wise to make sure wheel hardware, alignment condition, and clearance remain satisfactory after any recent wheel or suspension work.
