The 2019 Audi Trucks Q5 sits in the modern luxury crossover segment where everyday usability, all-weather confidence, and a refined road feel matter just as much as appearance. Its tire fitment reflects that balance, with three primary radial sizes used across the model range: 235/60R18, 235/55R19, and 255/45R20. That means the first step is confirming the exact trim and wheel diameter rather than assuming every Q5 uses the same setup. From there, the choice becomes more specific, especially for 20-inch applications where available tires differ by brand, series, and sidewall presentation. Owners should match the tire to the wheel already on the vehicle and to the way the Q5 is actually driven.
Which Tire Size Is Right for The 2019 Audi Trucks Q5
The 2019 Audi Trucks Q5 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter already on the vehicle. These are all radial fitments, but they span 18-inch, 19-inch, and 20-inch rims, so confirming wheel diameter is the first step before comparing tire choices or appearance details.
The size 235/55R19 describes a radial tire that is 235 millimeters wide, uses a 55-series aspect ratio, and fits a 19-inch rim. On the 2019 Audi Trucks Q5, this is one of the core modern radial fitments and appears across more than one sub-model. Its overall dimensions keep it very close to the other factory-style size paths used on this vehicle, which helps explain why trim and wheel confirmation matter so much. This size is the right place to focus when the Q5 is already equipped with 19-inch wheels and the goal is to maintain that setup.
The size 235/60R18 is a metric radial tire with a 235-millimeter section width, a 60-series profile, and an 18-inch rim diameter. On the 2019 Audi Trucks Q5, it serves as an 18-inch primary fitment rather than an alternate description of the 19-inch or 20-inch setup. Its section width is similar to the 235/55R19 size, but the wheel diameter is different, so the tire must match the wheel that is actually on the vehicle. This size should be considered when the Q5 carries the 18-inch wheel package and the owner wants to stay with that configuration.
The size 255/45R20 is a metric radial tire that uses a wider 255-millimeter section width, a 45-series profile, and a 20-inch rim. For the 2019 Audi Trucks Q5, this size is tied to 20-inch wheel applications and brings the broadest visible product choice, including BFGoodrich, Nitto, and Pro-Trac offerings. Available tires in this size also vary by sidewall treatment, with Blackwall, raised white letter, and Redline options. It is the size to evaluate when the Q5 already wears 20-inch wheels and the owner wants to compare brand character and appearance details within the correct fitment.
Sub-model fitment on the 2019 Audi Trucks Q5 is not completely uniform, because each trim can use more than one wheel and tire combination. Checking the exact Premium, Premium Plus, or Prestige setup matters before selecting a tire, especially since rim diameter changes with the size.

2019 Audi Trucks Q5 Premium
The 2019 Audi Trucks Q5 Premium uses either an 18-inch or 19-inch radial tire setup, so wheel confirmation comes first on this trim. Once that is settled, tire selection is mainly about matching the existing wheel package rather than choosing between radically different constructions.
The 2019 Audi Trucks Q5 Premium Plus can use either the 19-inch radial setup or the wider 20-inch radial setup. That makes wheel diameter the key detail, and owners moving into the 20-inch fitment will also see more variation in tire series and sidewall style.
The 2019 Audi Trucks Q5 Prestige shares the same basic fitment pattern as Premium Plus, using either a 19-inch or 20-inch radial tire configuration. Tire selection depends first on the wheel already installed, then on whether the goal is a straightforward Blackwall look or a more distinctive sidewall presentation in the 20-inch 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 questions for the 2019 Audi Trucks Q5 usually come down to identifying the correct tire size by trim and wheel diameter, then comparing radial tire choices, sidewall styles, and practical fitment checks before road use.
Tire Size & Fitment
What tire size fits a 2019 Audi Trucks Q5?
The 2019 Audi Trucks Q5 uses three primary tire sizes: 235/60R18, 235/55R19, and 255/45R20. All three are radial sizes, and the correct one depends on the trim level and the wheel package already on the vehicle rather than the model name alone.
A quick visual check of the wheel diameter is the most practical starting point because this Q5 uses 18-inch, 19-inch, and 20-inch fitments. After that, confirm the exact size on the current tire placard or sidewall, especially if the vehicle may have had wheel changes since new.
What size rim does a 2019 Audi Trucks Q5 use?
The 2019 Audi Trucks Q5 uses three rim diameters depending on configuration: 18 inches, 19 inches, and 20 inches. Those rim diameters correspond to the primary tire sizes 235/60R18, 235/55R19, and 255/45R20.
Rim diameter has to match the tire exactly, so a 19-inch tire cannot be mounted on an 18-inch or 20-inch wheel. If the Q5 has aftermarket wheels or a replacement wheel set, confirm the actual wheel size on the vehicle before choosing a tire by trim name alone.
Do all 2019 Audi Trucks Q5 sub-models use the same tire size?
No. The 2019 Audi Trucks Q5 Premium can use 235/60R18 or 235/55R19, while Premium Plus and Prestige can use 235/55R19 or 255/45R20. The fitment overlaps in places, but the entire Q5 range does not share one universal tire size.
That means trim identification helps, but wheel confirmation is still essential because even the same sub-model can appear with more than one size. The most reliable approach is to match the tire to the wheel currently installed and then compare options within that exact size.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2019 Audi Trucks Q5?
Start with the basics: the tire must be 255/45R20 and built for a 20-inch wheel. In this size, available choices differ by brand, tire series, sidewall style, and certain specifications such as rim-width range and, in one case, a stated maximum load capacity of 1819@51.
Once the fitment is confirmed, the next decision is how you want the Q5 to look and what kind of product character suits the vehicle. Some owners will prefer a simple Blackwall presentation, while others may want raised white letters or a Redline sidewall for a more distinctive appearance.
What sidewall styles are available for 2019 Audi Trucks Q5 tires?
In the available 255/45R20 product selection for the 2019 Audi Trucks Q5, sidewall styles include Blackwall, RWL, and Redline. Those choices create a noticeable appearance difference even when the overall tire size remains the same.
Sidewall style does not change the required tire size, but it can strongly influence how the vehicle presents visually. Matching the sidewall to the Q5's wheels and overall look is worthwhile, especially on 20-inch applications where the tire is a more visible part of the vehicle's stance.
What brands offer tires for the 2019 Audi Trucks Q5?
For the 255/45R20 fitment on the 2019 Audi Trucks Q5, available brands include BFGoodrich, Nitto, and Pro-Trac. The tires also span 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 deciding factor. It helps to compare the full package within the correct size, including sidewall style, stated rim-width compatibility where available, and whether the overall look of the tire matches the way the Q5 is used and presented.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2019 Audi Trucks Q5?
On a 2019 Audi Trucks Q5, tire construction is straightforward because the primary fitments are radial. The bigger appearance difference comes from tire size and sidewall treatment, particularly in the 255/45R20 fitment where Blackwall, raised white letter, and Redline options create very different visual results.
A restoration-minded or carefully preserved Q5 benefits from a tire that suits the vehicle's wheel design and overall presentation. Owners aiming for a clean modern look may lean toward Blackwall, while a more personalized build may call for a bolder sidewall choice within the same size.
Does correct tire fitment matter for a 2019 Audi Trucks Q5 restoration?
Yes. Correct tire fitment matters on a 2019 Audi Trucks Q5 because the model uses multiple wheel diameters and more than one primary tire size across its trims. Keeping the tire matched to the actual wheel on the vehicle preserves the intended stance and avoids needless fitment complications.
Appearance is only part of the equation. A Q5 that has been carefully maintained or cosmetically restored still benefits from confirming wheel size, tire dimensions, and clearance before mounting replacements, especially if the vehicle has ever received accessory wheels or suspension changes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Audi Trucks Q5?
Yes. Wheel changes, offset differences, suspension lowering, or other modifications can affect tire fitment on a 2019 Audi Trucks Q5 even when the tire size looks close to a stock configuration. That matters most here because the Q5 already uses 18-inch, 19-inch, and 20-inch factory-style size paths.
A modified Q5 should be checked for actual wheel diameter, wheel width, and clearance at the fender and steering components before replacement tires are chosen. Using the existing tire sidewall as the only guide can be misleading if the vehicle no longer carries its original wheel setup.
What should I inspect before driving a 2019 Audi Trucks Q5 on new tires?
Before driving a 2019 Audi Trucks Q5 on new tires, confirm that the size matches the wheel, check inflation pressure, and make sure each tire clears properly at full steering lock. It is also smart to inspect the wheels themselves for damage or irregular wear that may affect mounting and balance.
A short test drive should include attention to vibration, pull, rubbing, or any unusual contact noise. After the first miles, recheck pressure and give the tires a visual inspection so any issue tied to wheel condition, alignment, or clearance can be caught early.
How often should tires on a 2019 Audi Trucks Q5 be inspected?
Tires on a 2019 Audi Trucks Q5 should be inspected regularly, not just when replacement time arrives. Look at tread wear, sidewall condition, cuts, bulges, and signs of air loss, especially if the vehicle is driven seasonally or sits for longer periods between trips.
Routine checks are particularly helpful on a Q5 because different trims and wheel packages may use different tire sizes, making like-for-like replacement important. Catching irregular wear early can also point to alignment, suspension, or wheel issues before they shorten the life of the next tire set.
