The 2017 Audi Trucks SQ5 blends compact luxury utility with the sharper character expected from Audi’s S-badged performance lineup. It sits in a modern segment where wheel and tire choice plays a major role in both appearance and road feel, especially on larger-diameter factory-style setups. For this exact SQ5, the primary fitments are radial sizes 255/45R20 and 255/40R21, so the first decision is confirming which wheel diameter is actually on the vehicle. From there, the choice centers on tire series, brand, and sidewall presentation rather than vintage construction changes. That makes wheel verification, overall setup, and intended street use the key parts of selecting the right tire.
Which Tire Size Is Right for The 2017 Audi Trucks SQ5
The 2017 Audi Trucks SQ5 uses two primary tire sizes, and the difference comes down first to wheel diameter: 20-inch or 21-inch. Both are radial metric fitments, and both SQ5 sub-models can use either size, so the most important step is confirming the actual wheels on the vehicle before choosing a tire.
255/40R21 is a modern metric radial size in which 255 indicates section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 21 is the rim diameter in inches. On the 2017 Audi Trucks SQ5, this size represents the larger-wheel fitment and keeps the decision centered on proper 21-inch wheel matching rather than construction type. Its low-profile metric format suits buyers focused on retaining the vehicle’s larger-diameter tire presentation. Before selecting this size, confirm that the SQ5 still wears 21-inch wheels and has the clearance and wheel specifications to match.
255/45R20 is a metric radial size that uses a 255-millimeter section width, a 45-series profile, and a 20-inch rim diameter. For the 2017 Audi Trucks SQ5, this fitment opens the most visible product choice, including BFGoodrich, Nitto, and Pro-Trac options with Blackwall, raised white letter, and Redline sidewall treatments across several tire series. That gives the buyer more room to balance appearance and product character within the correct size. The practical step is confirming a 20-inch wheel setup and comparing the available sidewall style and series details against the way the vehicle is driven and presented.
Tire fitment is straightforward across the covered 2017 Audi Trucks SQ5 sub-models because Premium Plus and Prestige share the same two radial tire sizes. The real checkpoint is not trim level, but whether the vehicle is on 20-inch or 21-inch wheels.

2017 Audi Trucks SQ5 Premium Plus
The 2017 Audi Trucks SQ5 Premium Plus uses the same two radial fitment paths found across the model line, with tire choice tied to 20-inch or 21-inch wheels. That means selection starts with wheel confirmation, then moves to the right tire series and sidewall style for the way the vehicle is set up.
The 2017 Audi Trucks SQ5 Prestige follows the same tire-size pattern as Premium Plus, so trim alone does not change the basic fitment picture. Choosing the right tire comes down to verifying the installed wheel diameter and then comparing the available radial options within that size.
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.

Common 2017 Audi Trucks SQ5 tire questions usually come down to identifying the correct 20-inch or 21-inch fitment, comparing available radial choices, and checking wheel, clearance, and condition details before regular road use.
Tire Size & Fitment
What tire size fits a 2017 Audi Trucks SQ5?
The 2017 Audi Trucks SQ5 uses two primary tire sizes: 255/45R20 and 255/40R21. Both are radial metric fitments, and both the Premium Plus and Prestige sub-models use this same size range rather than having trim-specific tire sizing.
The important step is verifying which wheels are actually on the vehicle before choosing a tire. A 20-inch wheel requires the 255/45R20 fitment, while a 21-inch wheel requires 255/40R21. If the SQ5 has aftermarket wheels or a changed suspension setup, check wheel dimensions and clearance before replacing tires.
What size rim does a 2017 Audi Trucks SQ5 use?
A 2017 Audi Trucks SQ5 uses either a 20-inch or 21-inch rim, depending on which tire size is on the vehicle. The 255/45R20 fitment matches a 20-inch rim, and the 255/40R21 fitment matches a 21-inch rim.
That rim diameter difference is the key reason there are two valid tire sizes for this SQ5. Tire selection should always start with the wheel already on the vehicle, not just the model name. Looking at the existing sidewall size marking is the quickest check, and aftermarket wheel changes should be confirmed before ordering replacements.
Do all 2017 Audi Trucks SQ5 sub-models use the same tire size?
Yes. The 2017 Audi Trucks SQ5 Premium Plus and Prestige both use the same two tire sizes: 255/45R20 and 255/40R21. In other words, sub-model does not change the fitment range covered here; wheel diameter does.
That makes this a wheel-confirmation question more than a trim question. Once the actual 20-inch or 21-inch setup is confirmed, the next step is comparing tire options within that size for sidewall style, series, and other specifications. On a modified SQ5, check that the current tire size still matches the wheel and available clearance.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2017 Audi Trucks SQ5?
Start with the correct size, radial construction, and wheel compatibility. On the 2017 Audi Trucks SQ5, 255/45R20 opens several product paths, including BFGoodrich, Nitto, and Pro-Trac options, so the decision becomes one of tire series, sidewall style, and supporting specifications rather than basic size alone.
It helps to compare rim-width compatibility, sidewall appearance, and load details where they are stated. Some buyers will want a simple Blackwall look, while others may prefer raised white letter or Redline styling. Matching the tire to the SQ5’s actual wheel setup and intended street use is more useful than choosing by brand name alone.
What sidewall styles are available for 2017 Audi Trucks SQ5 tires?
For the 255/45R20 fitment on the 2017 Audi Trucks SQ5, available sidewall styles include Blackwall, RWL, and Redline. Blackwall appears across several options, while the Pro-Trac Street Pro III line adds the choice of raised white letter or Redline presentation.
That sidewall difference mainly affects the vehicle’s visual character rather than the basic fitment. A Blackwall suits a more understated modern look, while RWL or Redline creates a more deliberate enthusiast-style appearance. The right choice depends on how the SQ5 is presented and whether the owner wants the tire to blend in or stand out.
What brands offer tires for the 2017 Audi Trucks SQ5?
The 2017 Audi Trucks SQ5 has 255/45R20 tire options from BFGoodrich, Nitto, and Pro-Trac. Those choices appear across several radial tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III.
Brand alone should not be the only deciding factor. It makes more sense to compare the exact size, sidewall treatment, rim-width suitability where stated, and the general character of the tire series. That approach helps narrow the field to a tire that suits both the SQ5’s wheel setup and the owner’s preferred appearance.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Audi Trucks SQ5?
A period-style approach on a 2017 Audi Trucks SQ5 usually means keeping the correct modern metric radial size for the wheel diameter already on the vehicle, then choosing a tire whose sidewall treatment fits the look you want. For the available 255/45R20 options, that can mean a subtle Blackwall or a more expressive RWL or Redline presentation.
Because this is a modern performance SUV, appearance decisions are more about preserving the vehicle’s era-appropriate character than recreating a vintage tire style. Start with the confirmed wheel size, then choose the sidewall and series that suit the SQ5’s visual direction. If exact original-delivery appearance matters, compare against vehicle-specific reference material before making a final choice.
How does tire construction affect the appearance of a restored 2017 Audi Trucks SQ5?
Construction is simple on this vehicle because the primary fitments are radial, so the visual difference comes less from bias-ply-versus-radial choices and more from size, profile, and sidewall styling. On a 2017 Audi Trucks SQ5, the 20-inch and 21-inch fitments already create different visual proportions at the wheel opening.
That means appearance planning should focus on keeping the correct size for the installed wheels and selecting a sidewall treatment that suits the vehicle’s finished look. A Blackwall keeps the presentation restrained, while RWL or Redline adds more visual emphasis. Confirming the existing wheel setup first prevents the appearance goal from overriding basic fitment accuracy.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Audi Trucks SQ5?
Yes. Modifications such as aftermarket wheels, suspension lowering, spacer changes, or other wheel-position changes can affect tire fitment on a 2017 Audi Trucks SQ5 even when the tire size looks close to stock. The vehicle’s two valid sizes also use different rim diameters, so setup changes matter immediately.
A changed wheel width or offset can alter clearance at the fender, suspension, or steering components. Before replacing tires, compare the actual wheel diameter and check how the current setup sits in the wheel opening. That extra step matters most when the SQ5 no longer runs the same wheel and suspension combination it left with.
What should I inspect before driving a 2017 Audi Trucks SQ5 on new tires?
Check that the new tires match the wheel diameter, are seated and inflated properly, and have adequate clearance through the steering range. It is also smart to inspect the wheels for damage and look over the suspension and alignment condition, especially on a performance-oriented vehicle like the 2017 Audi Trucks SQ5.
Road use is smoother when the rest of the setup supports the new tires. Uneven wear, vibration, or pulling can point to alignment or wheel issues rather than the tire itself. A short, careful initial drive helps confirm there is no rubbing, unusual noise, or air loss before the vehicle returns to normal use.
What should I check before a longer drive in a 2017 Audi Trucks SQ5?
Before a longer drive, inspect tire pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. On a 2017 Audi Trucks SQ5, also confirm that the tires are the correct 20-inch or 21-inch fitment for the wheels currently installed and that no rubbing appears at full steering lock.
Longer trips put more stress on any unresolved fitment or condition issue. It helps to recheck pressures when the tires are cold and make sure there has been no slow air loss after installation. If the SQ5 has sat for extended periods or uses aftermarket wheels, a closer inspection before departure is worthwhile.
