The 2020 Audi Trucks Q5 sits in the modern luxury crossover class where ride quality, all-season drivability, and sharp road manners all matter just as much as curb appeal. For many owners, the tire decision comes down to matching the vehicle’s exact trim and wheel package rather than simply choosing by model name alone. This Q5 uses radial tires, with fitment spread across 235/60R18, 235/55R19, and 255/45R20 sizes depending on sub-model and wheel setup. Available choices also vary by brand, tire series, and sidewall treatment, including blackwall, raised white letter, and redline options in 20-inch fitment. The smart starting point is confirming trim level and wheel diameter before comparing style and road-use priorities.
Which Tire Size Is Right for The 2020 Audi Trucks Q5
The 2020 Audi Trucks Q5 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three are radial fitments, but they are tied to 18-inch, 19-inch, or 20-inch rims, so confirming the wheel currently on the vehicle is the first step before comparing tire choices.
A 235/55R19 tire uses a 235-millimeter section width, a 55-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2020 Audi Trucks Q5, this size represents one of the main modern radial fitments and appears across more than one covered sub-model. Its overall proportions keep it very close to the other Q5 fitments, but the 19-inch wheel requirement remains the key distinction. This size makes sense when the vehicle is already equipped with 19-inch wheels and the goal is to stay with the intended wheel-and-tire relationship.
A 235/60R18 tire combines a 235-millimeter section width with a 60-series profile, radial construction, and an 18-inch rim diameter. For the 2020 Audi Trucks Q5, this size is tied to an 18-inch wheel setup rather than the 19-inch or 20-inch alternatives used elsewhere in the range. Its dimensions place it in the same general fitment family, but the wheel diameter is different enough that tire selection must begin there. This is the size to evaluate when the Q5 has the 18-inch package and the goal is to preserve proper wheel compatibility.
A 255/45R20 tire is wider than the other Q5 fitments, using a 255-millimeter section width, a 45-series profile, radial construction, and a 20-inch rim. This size is used on certain 2020 Audi Trucks Q5 sub-models with the larger wheel package, and it has the broadest visible product variety here, including BFGoodrich, Nitto, and Pro-Trac choices. Sidewall treatments include blackwall, raised white letter, and redline, with series differences that shape the tire’s look and intended character. It is the size to confirm when the vehicle has 20-inch wheels and appearance choice matters alongside fitment.
Sub-model fitment on the 2020 Audi Trucks Q5 is not completely uniform, because tire size changes with the trim and wheel package. Checking the exact Premium, Premium Plus, or Prestige configuration helps narrow the correct rim diameter before comparing actual tire options.

2020 Audi Trucks Q5 Premium
The 2020 Audi Trucks Q5 Premium uses either 235/60R18 or 235/55R19 radial tires, so wheel diameter is the key detail to confirm on the vehicle itself. That means tire selection starts with the existing 18-inch or 19-inch setup rather than the trim name alone.
The 2020 Audi Trucks Q5 Premium Plus uses either 235/55R19 or 255/45R20 radial tires depending on the wheel package in place. For this sub-model, the practical decision is confirming whether the vehicle carries the 19-inch or 20-inch setup before comparing brand, series, and sidewall options.
The 2020 Audi Trucks Q5 Prestige also uses either 235/55R19 or 255/45R20 radial tires, so trim level alone does not settle the fitment question. Tire selection becomes much easier once the current wheel diameter is verified, especially if appearance details like blackwall, RWL, or redline matter.
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 questions for the 2020 Audi Trucks Q5 usually focus on matching the correct tire size to the trim and wheel package, then comparing radial options by brand, sidewall style, and real-world fitment considerations.
Tire Size & Fitment
What tire size fits a 2020 Audi Trucks Q5?
The 2020 Audi Trucks Q5 uses three primary tire sizes: 235/60R18, 235/55R19, and 255/45R20. All are radial sizes, but they do not apply universally across every Q5 configuration because fitment changes with sub-model and wheel package.
The practical first step is checking the tire size already mounted on the vehicle or confirming the wheel diameter before choosing a replacement. A Q5 on 18-inch wheels needs a different tire than one on 19-inch or 20-inch wheels, even though the model name is the same.
What size rim does a 2020 Audi Trucks Q5 use?
A 2020 Audi Trucks Q5 can use 18-inch, 19-inch, or 20-inch rims depending on the exact trim and wheel setup. Those rim diameters correspond to 235/60R18, 235/55R19, and 255/45R20 tire sizes.
Matching the tire to the actual rim diameter is essential because the final number in the tire size must agree with the wheel. Before replacing tires, check the wheel itself and the current sidewall markings so the new tire matches the Q5’s existing wheel package.
Do all 2020 Audi Trucks Q5 sub-models use the same tire size?
No, the 2020 Audi Trucks Q5 sub-models do not all use the same tire size. Premium models use 235/60R18 or 235/55R19, while Premium Plus and Prestige models use 235/55R19 or 255/45R20.
That overlap can cause confusion because two trims may share one size while differing on the second option. The safest approach is to verify both the exact sub-model and the wheel currently on the vehicle, especially if it may have been changed from its original wheel package.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Audi Trucks Q5?
Start with the correct primary size for the vehicle’s trim and wheel diameter: 235/60R18, 235/55R19, or 255/45R20. From there, the main selection factors are construction, brand, tire series, sidewall style, and any stated rim-width or load details that apply to the exact tire.
A good choice depends on how the Q5 is used and how closely the replacement should match the existing setup. Owners comparing 255/45R20 options, for example, may care as much about appearance and sidewall treatment as they do about series differences and wheel compatibility.
What sidewall styles are available for 2020 Audi Trucks Q5 tires?
Among the available 255/45R20 options for the 2020 Audi Trucks Q5, sidewall styles include blackwall, raised white letter, and redline. Those treatments create distinctly different visual effects even when the tire size remains the same.
Sidewall style does not change the required wheel diameter, but it can significantly affect how the vehicle looks. Blackwall keeps a modern, understated appearance, while raised white letter and redline add a more custom or enthusiast-oriented presentation that some owners may prefer on 20-inch wheels.
What brands offer tires for the 2020 Audi Trucks Q5?
The available 255/45R20 tire choices for the 2020 Audi Trucks Q5 include BFGoodrich, Nitto, and Pro-Trac. Those options also span more than one tire series, so brand is only one part of the buying decision.
Comparing brand choices makes more sense after the correct size is confirmed, since the Q5 also uses 18-inch and 19-inch fitments. Once size is settled, look at sidewall style, series character, and any stated rim-width or load details instead of choosing on brand name alone.
Restoration & Appearance
How does tire construction affect the appearance of a 2020 Audi Trucks Q5?
On a 2020 Audi Trucks Q5, the primary fitments are radial, so the appearance difference comes less from construction changes and more from tire size, profile, and sidewall treatment. A 20-inch fitment with blackwall, raised white letter, or redline can present the vehicle very differently than a more understated wheel-and-tire package.
Owners who care about presentation should match the tire visually to the Q5’s overall look rather than focusing only on dimensions. Wheel diameter, section width, and sidewall styling all influence stance and character, so appearance-minded buyers should confirm the complete package before making a change.
Does correct tire fitment matter for a 2020 Audi Trucks Q5 restoration or appearance-focused build?
Yes, correct tire fitment matters because the 2020 Audi Trucks Q5 uses multiple sizes tied to different wheel diameters. Using the right 18-inch, 19-inch, or 20-inch fitment helps preserve the intended proportions and avoids turning an appearance upgrade into a basic compatibility problem.
An appearance-focused build still needs the fundamentals right first, especially wheel diameter and the proper tire size for that wheel. Once those are confirmed, sidewall choices such as blackwall, raised white letter, or redline can shape the final look without drifting away from sound fitment practice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Audi Trucks Q5?
Yes, modifications can affect tire fitment on a 2020 Audi Trucks Q5. Changes such as aftermarket wheels, different wheel widths, altered offsets, suspension lowering, or body changes can all influence whether the original 235/60R18, 235/55R19, or 255/45R20 sizing still works as intended.
Any Q5 with non-stock wheels or suspension should be checked for clearance at the fenders, suspension components, and steering range before new tires are installed. Even when the tire size sounds familiar, the actual wheel and chassis setup determines whether the fitment remains appropriate.
What should I inspect before driving a 2020 Audi Trucks Q5 on new tires?
Before driving a 2020 Audi Trucks Q5 on new tires, confirm that the size matches the wheel diameter and that all tires are properly mounted and inflated. It is also wise to look over the wheels for damage and make sure there is no visible interference around the suspension or fender openings.
A short initial check can prevent larger problems later. After installation, recheck air pressure, watch for any vibration, and inspect for rubbing during full steering lock or normal suspension movement, especially if the Q5 has 20-inch wheels or any aftermarket changes.
How often should tires on a 2020 Audi Trucks Q5 be inspected?
Tires on a 2020 Audi Trucks Q5 should be inspected regularly, not just when tread appears low. Frequent checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage help catch issues early, particularly on vehicles that see mixed city and highway use.
Routine inspection matters even more if the Q5 is driven infrequently or sits for long periods, since low-use vehicles can still develop age-related tire concerns. Looking over the tires at the same time as basic vehicle maintenance keeps the wheel-and-tire package safer and easier to manage.
