The 2023 Audi Trucks SQ5 blends modern sport-utility utility with the quick responses and road manners expected from Audi’s S-badged performance lineup. It sits in a part of the market where wheel-and-tire choice has a major effect on stance, ride character, and overall appearance. For this exact SQ5, the primary fitments are 255/45R20 and 255/40R21, both modern metric radial sizes with nearly identical overall diameter but different rim diameters. That means the key choice is not just tire brand, but confirming whether the vehicle is on 20-inch or 21-inch wheels and then comparing the available series and sidewall treatments that suit your driving and styling goals.
Which Tire Size Is Right for The 2023 Audi Trucks SQ5
The 2023 Audi Trucks SQ5 uses two primary tire sizes, and the first step is confirming whether the vehicle has 20-inch or 21-inch wheels. Both fitments are radial and both appear across the covered sub-models, so the decision centers on actual wheel diameter first, then the tire style and product options available in the matching size.
Fit(s): Premium, Premium Plus, Premium Plus w/Air Suspension, Premium w/Air Suspension, Prestige, and Prestige w/Air Suspension
Construction: Radial|Rim: 21 in
A 255/40R21 tire uses a 255 millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 21-inch rim. On the 2023 Audi Trucks SQ5, this is the lower-profile of the two primary fitments, so wheel diameter matters as much as tire size. Its overall diameter stays very close to the 20-inch option, which helps explain why both sizes can appear across the same sub-model range. This size should be evaluated by confirming the SQ5’s existing wheel package and making sure any replacement matches the vehicle’s present rim and clearance setup.
Fit(s): Premium, Premium Plus, Premium Plus w/Air Suspension, Premium w/Air Suspension, Prestige, and Prestige w/Air Suspension
Construction: Radial|Rim: 20 in
A 255/45R20 tire carries the same 255 millimeter nominal width as the 21-inch fitment, but with a 45-series profile on a 20-inch rim. For the 2023 Audi Trucks SQ5, this size opens the most visible product choice here, including BFGoodrich, Nitto, and Pro-Trac options in blackwall, raised white letter, and redline presentations. Tire series also vary, with g-Force and Street Pro III choices giving the buyer more than one visual and use-oriented direction. This is the size to compare carefully if the SQ5 already wears 20-inch wheels and appearance matters as much as the basic fitment.
Tire fitment is straightforward across the covered 2023 Audi Trucks SQ5 sub-models because each one can use the same two primary radial sizes. The important check is not trim name alone, but whether the vehicle is currently equipped with 20-inch or 21-inch wheels.

2023 Audi Trucks SQ5 Premium
The 2023 Audi Trucks SQ5 Premium can use the same two radial fitments found across the broader SQ5 range. Tire selection comes down to verifying whether the vehicle is on 20-inch or 21-inch wheels and then choosing the product style that matches its current setup and intended use.
The 2023 Audi Trucks SQ5 Premium Plus shares the same two primary radial tire sizes as the other covered SQ5 configurations. That keeps fitment simple at the trim level, but wheel diameter still needs to be confirmed before comparing available tire series and sidewall treatments.
2023 Audi Trucks SQ5 Premium Plus w/Air Suspension
The 2023 Audi Trucks SQ5 Premium Plus w/Air Suspension uses the same two primary radial tire sizes as the rest of the covered SQ5 lineup. The practical step is confirming the actual wheel diameter on the vehicle, then checking that the replacement tire matches both the wheel and the SQ5’s present ride-height setup.
The 2023 Audi Trucks SQ5 Premium w/Air Suspension follows the same basic tire-fitment pattern as the other listed SQ5 sub-models. Selection still depends on whether the vehicle has 20-inch or 21-inch wheels, especially when comparing profile, appearance, and clearance.
The 2023 Audi Trucks SQ5 Prestige uses the same pair of primary radial sizes as the other covered SQ5 trims. That means tire choice is less about the Prestige name itself and more about confirming the wheel package already on the vehicle before moving into brand or sidewall preferences.
The 2023 Audi Trucks SQ5 Prestige w/Air Suspension also shares the same two primary radial tire sizes used across the listed SQ5 sub-models. Buyers should verify actual wheel diameter first, then compare replacement options with attention to profile, appearance, and running clearance on the current suspension 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.

Tire Size & Fitment
What tire size fits a 2023 Audi Trucks SQ5?
The 2023 Audi Trucks SQ5 uses two primary tire sizes: 255/45R20 and 255/40R21. Both are radial metric sizes, and both appear across the covered SQ5 sub-models, including Premium, Premium Plus, Prestige, and the air-suspension variations.
The key step is confirming which wheel package is actually on the vehicle, because the two sizes use different rim diameters even though their overall diameter is very close. Looking at the tire sidewall or measuring the wheel before ordering helps prevent choosing a 20-inch tire for a 21-inch wheel, or the reverse.
What size rim does a 2023 Audi Trucks SQ5 use?
A 2023 Audi Trucks SQ5 can use either a 20-inch or 21-inch rim, depending on which of the two primary tire sizes is on the vehicle. The 255/45R20 size uses a 20-inch rim, while the 255/40R21 size uses a 21-inch rim.
That wheel-diameter difference is the most important fitment detail on this SQ5 page. The two tire sizes are close in overall diameter, but they are not meant for the same rim, so replacement starts with the actual wheel size already installed on the vehicle rather than the trim name alone.
Do all 2023 Audi Trucks SQ5 sub-models use the same tire size?
The covered 2023 Audi Trucks SQ5 sub-models share the same two primary tire sizes: 255/45R20 and 255/40R21. That includes Premium, Premium Plus, Prestige, and the versions equipped with air suspension, so fitment stays consistent across the listed sub-model range.
Even with that shared fitment pattern, the exact tire to purchase still depends on the wheels currently on the SUV. A buyer should check the existing sidewall marking or wheel diameter and avoid assuming that every SQ5 with the same trim name automatically wears the same wheel package today.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2023 Audi Trucks SQ5?
Start with the correct size, then compare construction details and product character within 255/45R20. The available choices here are all radial tires, but they differ by brand, tire series, sidewall style, and in some cases rim-width specification, weight, and stated load information.
A practical comparison should include how the SQ5 is used and how the tire should look on the vehicle. Blackwall suits a subdued modern appearance, while raised white letter or redline creates a more distinctive presentation, and wheel-width compatibility should always be checked against the actual 20-inch wheel before final selection.
What sidewall styles are available for 2023 Audi Trucks SQ5 tires?
Within the available 255/45R20 products for the 2023 Audi Trucks SQ5, sidewall styles include Blackwall, RWL, and Redline. Blackwall appears on BFGoodrich and Nitto options, while Pro-Trac Street Pro III adds raised white letter and redline choices in the same size.
That makes sidewall treatment a real appearance decision rather than a minor specification. Buyers who want a cleaner late-model look often stay with blackwall, while RWL or redline can change the visual tone of the SQ5 considerably, so the sidewall should be chosen to match the vehicle’s overall style as well as its wheel size.
What brands offer tires for the 2023 Audi Trucks SQ5?
For the available 255/45R20 fitment on the 2023 Audi Trucks SQ5, the brands shown are BFGoodrich, Nitto, and Pro-Trac. Those options span multiple tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice should be treated as one part of a larger comparison rather than the entire decision. It helps to look at the exact size marking, sidewall style, rim-width compatibility where stated, and the overall look you want on the SQ5, especially if the vehicle’s wheel package and visual presentation both matter.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Audi Trucks SQ5?
A period-style approach is less about restoration in the vintage sense and more about choosing a tire that supports the SQ5’s intended visual character. For the available 255/45R20 fitment, options range from understated blackwall tires to Pro-Trac Street Pro III versions with raised white letters or a redline sidewall.
The right direction depends on whether the goal is a clean contemporary Audi look or something with more visual contrast. Size accuracy still comes first, so confirm the SQ5 is actually on 20-inch wheels before focusing on appearance, and use the sidewall treatment to complement the wheels rather than overpower them.
How does tire construction affect the appearance of a restored 2023 Audi Trucks SQ5?
On this 2023 Audi Trucks SQ5 page, construction does not create a bias-ply-versus-radial appearance decision because the primary fitments are radial. The visual difference comes more from sidewall treatment and tire series than from construction type, especially within the available 255/45R20 product choices.
That means appearance planning should focus on profile and sidewall presentation after the correct wheel diameter is confirmed. A blackwall tire keeps the look restrained, while raised white letters or a redline introduce a more assertive visual statement, so the tire can influence the SQ5’s personality even without changing its basic fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Audi Trucks SQ5?
Yes. Even when a 2023 Audi Trucks SQ5 starts with the correct 255/45R20 or 255/40R21 tire size, modifications can change how well that fitment works on the vehicle. Aftermarket wheels, altered offset, suspension changes, and ride-height adjustments can all affect clearance at the fender, inner wheelhouse, or steering components.
That matters even more on a performance-oriented SUV where wheel packages are often changed for style. Any SQ5 that has been lowered, fitted with different wheels, or otherwise modified should be checked for actual wheel diameter, width, and clearance before replacement tires are chosen, even if the sidewall size seems familiar.
What should I inspect before driving a 2023 Audi Trucks SQ5 on new tires?
Before driving a 2023 Audi Trucks SQ5 on new tires, inspect wheel condition, verify the tire size matches the wheel diameter, and confirm proper air pressure. It is also worth checking for rubbing at full steering lock, uneven suspension behavior, and any visible damage such as cuts, bulges, or air loss concerns.
A careful first inspection helps catch setup issues before normal road use. The SQ5 should also be aligned if there are signs of irregular wear or if suspension components have recently been changed, because a fresh tire can wear quickly if the wheel, alignment, or ride-height condition is already out of spec.
How often should tires on a 2023 Audi Trucks SQ5 be inspected?
Tires on a 2023 Audi Trucks SQ5 should be inspected regularly, with quick visual checks before routine driving and closer inspections at service intervals or whenever ride feel changes. Even on a newer vehicle, pressure loss, curb damage, uneven wear, and road-impact issues can affect a performance-oriented tire quickly.
A more thorough inspection is especially useful before a longer trip or after any wheel or suspension change. Looking at tread condition, sidewall integrity, and signs of rubbing gives a clearer picture of whether the current setup is still healthy, and it helps confirm that the chosen 20-inch or 21-inch fitment is behaving as expected.
