The 2017 Audi Trucks Q5 sits in the modern luxury crossover market where everyday usability, all-weather confidence, and upscale road manners all matter just as much as appearance. Its tire fitment reflects that balance, with four primary radial sizes used across the model range: 235/60R18, 235/55R19, 255/45R20, and 255/40R21. That means the first step is confirming the exact sub-model and wheel diameter rather than assuming every Q5 uses the same setup. For owners focused on replacement tires, the real choice is usually between maintaining the original size and selecting the right brand, series, and sidewall treatment for the vehicle's look and intended road use.
Which Tire Size Is Right for The 2017 Audi Trucks Q5
Four primary tire sizes apply to the 2017 Audi Trucks Q5, and they vary by sub-model and wheel diameter. Every fitment uses radial construction, but the correct choice depends on identifying the exact Q5 trim first and then confirming whether the vehicle has 18-inch, 19-inch, 20-inch, or 21-inch wheels. Once that is settled, the decision shifts to selecting the right tire style and product characteristics within the correct size.
Fit(s): Premium, Premium Plus 2.0, Premium Plus 3.0, and Prestige
Construction: Radial|Rim: 19 in
235/55R19 is a metric radial size in which 235 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 19 is the wheel diameter in inches. On the 2017 Audi Trucks Q5, this size is one of the mainstream fitments and supports the model's modern crossover driving character. It serves as a useful reference point when checking whether the vehicle is running a standard wheel package rather than a larger optional setup. Confirming the actual 19-inch wheel on the vehicle remains the key step before comparing replacement tires.
235/60R18 is a metric radial size that uses a 235-millimeter section width, a 60-series profile, and an 18-inch rim. This fitment appears on certain 2017 Audi Trucks Q5 sub-models and represents one of the smaller wheel packages used on the vehicle. Its sizing language is familiar to most modern buyers, but it still needs to be matched to the actual wheel diameter on the Q5 rather than chosen by model year alone. Owners replacing this size should focus on keeping the correct 18-inch fitment and then comparing tire type, intended use, and overall vehicle setup.
255/40R21 is a metric radial size with a 255-millimeter section width, a lower 40-series profile, and a 21-inch rim diameter. On the 2017 Audi Trucks Q5, this size belongs to specific upper trims rather than the full model range, so it should be chosen only after the wheel package is confirmed. The larger diameter and lower-profile format place the focus on exact wheel fitment and maintaining the intended proportions of the vehicle. This size makes the most sense for owners keeping the Q5's larger-wheel appearance and checking clearance carefully on any modified setup.
255/45R20 is a metric radial size that combines a 255-millimeter section width with a 45-series profile on a 20-inch wheel. For the 2017 Audi Trucks Q5, it is used on certain trims and also carries the clearest product selection, including BFGoodrich, Nitto, and Pro-Trac choices. Available sidewall treatments include Blackwall, raised white letter, and Redline, with tire series such as g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III. Buyers choosing this size should confirm the 20-inch wheel first, then compare appearance, series character, and rim-width compatibility.
Tire fitment on the 2017 Audi Trucks Q5 varies by sub-model, so trim identification matters before a replacement tire is selected. Some versions use 18-inch or 19-inch fitments, while others move to 20-inch or 21-inch wheel packages that change the correct tire size entirely.

2017 Audi Trucks Q5 Premium
The 2017 Audi Trucks Q5 Premium uses radial tire fitments in either an 18-inch or 19-inch wheel package. That means the best starting point is confirming which wheels are actually on the vehicle, then choosing a replacement tire that matches the intended use and overall presentation.
The 2017 Audi Trucks Q5 Premium Plus 2.0 also uses radial tires and shares the same 18-inch or 19-inch fitment pattern seen on other non-larger-wheel configurations. Tire selection here is mainly about matching the exact wheel diameter already on the Q5 before comparing available tire styles and performance-oriented options.
The 2017 Audi Trucks Q5 Premium Plus 3.0 spans three radial fitments, including 19-inch, 20-inch, and 21-inch wheel packages. Because this sub-model has the widest fitment spread, confirming the actual wheel diameter is more important than relying on trim name alone when selecting replacement tires.
The 2017 Audi Trucks Q5 Prestige uses radial tire fitments tied to 19-inch, 20-inch, or 21-inch wheels. Owners should verify the installed wheel package first, then decide whether the priority is maintaining the current appearance or comparing the available tire choices within the correct 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.

Tire Size & Fitment
What tire size fits a 2017 Audi Trucks Q5?
The 2017 Audi Trucks Q5 uses four primary radial tire sizes: 235/60R18, 235/55R19, 255/45R20, and 255/40R21. The correct size depends on the exact sub-model and the wheel package on the vehicle, so there is not one universal tire size for every Q5 in this model year.
The most important check is the actual wheel diameter on the vehicle before comparing tires. Premium and Premium Plus 2.0 models use 18-inch or 19-inch fitments, while Premium Plus 3.0 and Prestige can also use 20-inch or 21-inch setups. If the Q5 has aftermarket wheels, verify the current size rather than assuming it still matches its original trim configuration.
What size rim does a 2017 Audi Trucks Q5 use?
A 2017 Audi Trucks Q5 can use 18-inch, 19-inch, 20-inch, or 21-inch rims, depending on sub-model and wheel package. Those rim diameters correspond to the vehicle's four tire sizes: 235/60R18, 235/55R19, 255/45R20, and 255/40R21.
Wheel diameter should be confirmed before anything else because the tire size must match the rim size exactly. An 18-inch tire cannot be mounted on a 19-inch wheel, and the same logic applies across the larger fitments. It also helps to inspect the wheel itself for markings and compare the current setup against the installed tire size, especially if the Q5 has been modified since new.
Why does the 2017 Audi Trucks Q5 have more than one tire size?
The 2017 Audi Trucks Q5 has more than one tire size because different sub-models and wheel packages use different fitments. Some trims use 18-inch or 19-inch wheels, while Premium Plus 3.0 and Prestige can also carry 20-inch or 21-inch tire and wheel combinations.
That variation means trim name alone is not always enough to choose a replacement tire. The practical step is to identify both the sub-model and the actual wheel diameter currently on the vehicle, then match the tire size to that setup. This matters even more on a used Q5, where wheel upgrades or seasonal wheel sets may have changed the original configuration.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2017 Audi Trucks Q5?
Start with the basics: make sure the Q5 actually uses the 255/45R20 fitment and still has 20-inch wheels. Within that size, the main differences are brand, tire series, sidewall style, and rim-width compatibility, with available choices from BFGoodrich, Nitto, and Pro-Trac.
Selection usually comes down to how the Q5 is used and how you want it to look. Blackwall tires keep a modern appearance, while raised white letter or Redline options create a more customized presentation. It also helps to compare the wheel width against the tire's supported rim-width range, particularly if the vehicle is running non-original wheels.
What sidewall styles are available for 2017 Audi Trucks Q5 tires?
For the available 255/45R20 products used on the 2017 Audi Trucks Q5, sidewall styles include Blackwall, raised white letter, and Redline. Those choices give the same tire size a noticeably different visual character even when wheel diameter and general fitment stay the same.
Blackwall is usually the most understated option, while raised white letter and Redline treatments push the tire toward a more styled presentation. The key is to separate appearance choice from fitment choice, because sidewall treatment does not change the need to match the correct size and wheel. Owners aiming for a cleaner luxury look often make a different choice than those building a more customized Q5.
What brands offer tires for the 2017 Audi Trucks Q5?
The available 255/45R20 tires for the 2017 Audi Trucks Q5 come from BFGoodrich, Nitto, and Pro-Trac. Those products cover several 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 filter when choosing a tire for this Q5. It is smarter to compare the exact size, construction, sidewall appearance, and any wheel-width requirements that matter for the vehicle's current setup. Looking at the series name and sidewall treatment together often makes it easier to narrow the options to the tire that best suits the Q5's intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Audi Trucks Q5?
A period-style choice for a 2017 Audi Trucks Q5 starts with keeping the correct original-type size and wheel diameter already on the vehicle, since this is a modern radial-fitment crossover rather than a classic bias-ply application. From there, appearance usually comes down to whether the Q5 looks best with a straightforward Blackwall tire or a more styled sidewall treatment.
For a stock-looking vehicle, the cleanest path is usually staying with the proper radial size and avoiding unnecessary changes in wheel diameter. A more customized presentation can point toward 255/45R20 options with raised white letter or Redline sidewalls. When exact showroom-era authenticity matters, compare the vehicle against original sales literature, wheel package details, and marque-specific reference material before finalizing the look.
How does tire construction affect the appearance of a restored 2017 Audi Trucks Q5?
Tire construction is straightforward on the 2017 Audi Trucks Q5 because all primary fitments are radial. That means the visual difference usually comes less from bias-ply-versus-radial appearance and more from the chosen size, wheel diameter, sidewall profile, and sidewall treatment within the correct radial format.
Keeping the proper 18-inch, 19-inch, 20-inch, or 21-inch fitment helps preserve the Q5's intended proportions. A lower-profile 20-inch or 21-inch package gives a different visual effect than the 18-inch and 19-inch fitments, even though all are correct for certain trims. Sidewall style matters too, since Blackwall reads more restrained while Redline or raised white letter makes the vehicle look more personalized.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Audi Trucks Q5?
Yes, modifications can affect tire fitment on a 2017 Audi Trucks Q5. Aftermarket wheels, changes in wheel width, suspension lowering, spacer use, or body modifications can all change how a tire sits in the wheel opening, even when the tire size matches one of the original Q5 fitments.
The practical concern is clearance at full steering lock and through suspension travel, especially on the wider 255-section sizes. It helps to verify wheel diameter, wheel width, and the tire size currently mounted before ordering replacements. Any Q5 that no longer has its original wheel and suspension setup deserves a closer visual inspection to avoid rubbing or mismatch problems.
What should I inspect before driving a 2017 Audi Trucks Q5 on new tires?
Before driving a 2017 Audi Trucks Q5 on new tires, inspect the wheels for damage, confirm that the mounted tire size matches the wheel diameter, and check inflation pressure carefully. It is also worth looking over valve stems, tread seating, and overall sidewall condition before putting the vehicle into regular road use.
A short initial drive should include attention to vibration, pull, rubbing, or any unusual contact during turning. Rechecking pressure after the first outings is a good habit, and so is inspecting the tire-to-fender and tire-to-suspension clearance with the steering turned both directions. That extra look matters most when the Q5 uses larger 20-inch or 21-inch fitments or has been modified.
How often should tires on a 2017 Audi Trucks Q5 be inspected?
Tires on a 2017 Audi Trucks Q5 should be inspected regularly, not just when they look low or start causing a problem. A quick visual check for cuts, bulges, irregular wear, cracking, or air loss is smart before longer drives, and a more careful inspection should be part of routine vehicle maintenance.
Even on a modern crossover, low-use patterns can hide age-related issues because the vehicle may not accumulate miles quickly enough to wear the tires out. Owners should also monitor tread condition and inflation pressure as the seasons change. If the Q5 is driven infrequently or stored for stretches, inspect the sidewalls and contact patch closely before returning it to regular road use.
