The 2019 Audi Trucks e-tron Quattro arrived at an important moment, blending Audi’s familiar premium SUV character with fully electric propulsion and the added weight, quietness, and instant torque that shape how tire choice feels on the road. For this exact model, fitment centers on three primary radial sizes: 255/55R19, 255/50R20, and 265/45R21. That means the main decision is less about vintage-style construction and more about matching the correct wheel diameter and sub-model setup. Some versions share more than one approved size, while others are tied to a single fitment, so wheel confirmation and trim-level accuracy come first before comparing tire options.
Which Tire Size Is Right for The 2019 Audi Trucks e-tron Quattro
The 2019 Audi Trucks e-tron Quattro uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Since these sizes span 19-inch, 20-inch, and 21-inch rims, the first step is confirming both the specific trim and the wheels currently on the vehicle before choosing a replacement tire.
255/50R20 is a metric radial size where 255 identifies the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 20 is the wheel diameter in inches. On the 2019 Audi Trucks e-tron Quattro, this size is one of the primary fitments used on select sub-models equipped with 20-inch wheels. Its role in the lineup makes it important to verify that the vehicle has the correct 20-inch wheel package rather than assuming it matches every trim. Buyers comparing replacement tires in this size should focus on proper wheel compatibility and the intended driving use of the vehicle.
255/55R19 follows the same metric radial sizing pattern, with a 255-millimeter nominal section width, a 55-series profile, radial construction, and a 19-inch rim diameter. This size serves as another primary fitment for the 2019 Audi Trucks e-tron Quattro and applies to certain sub-model and wheel combinations rather than the full range. Because it uses a different rim diameter than the 20-inch and 21-inch options, wheel confirmation is essential before moving ahead with a replacement. It is a useful size to evaluate when the vehicle retains its 19-inch setup and the goal is to stay with the proper original fitment range.
265/45R21 is a metric radial size with a 265-millimeter nominal section width, a 45-series profile, radial construction, and a 21-inch wheel diameter. On the 2019 Audi Trucks e-tron Quattro, this size is tied to the larger-wheel fitment used on specific upper trims and the Prestige Edition One configuration. Its meaning is straightforward, but the practical importance lies in recognizing that it is not interchangeable with the 19-inch or 20-inch primary sizes without a corresponding wheel change. This is the size to evaluate when the vehicle is already equipped with the 21-inch wheel package and that setup is being retained.
Sub-model fitment matters on the 2019 Audi Trucks e-tron Quattro because tire size changes with trim and wheel package. Some versions share more than one approved size, while others are tied to a single larger-wheel setup, so identifying the exact sub-model helps narrow the correct replacement quickly.

2019 Audi Trucks e-tron Quattro Premium Plus
The 2019 Audi Trucks e-tron Quattro Premium Plus uses radial fitments in either a 19-inch or 20-inch wheel configuration. Tire selection starts with confirming which wheel package is on the vehicle now, then choosing a replacement that matches that exact diameter and size.
The 2019 Audi Trucks e-tron Quattro Prestige has the widest fitment spread, with primary radial sizes tied to 19-inch, 20-inch, or 21-inch wheels. That makes wheel verification especially important before replacement, since the correct tire depends on the specific setup installed on the vehicle.
2019 Audi Trucks e-tron Quattro Prestige Edition One
The 2019 Audi Trucks e-tron Quattro Prestige Edition One uses the 21-inch radial fitment. For this sub-model, the tire decision is more straightforward, with the main focus shifting to maintaining the correct 21-inch size and confirming wheel condition before road use.
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.
Frequently Asked Questions
These FAQs focus on the exact tire sizes used on the 2019 Audi Trucks e-tron Quattro, how they vary by sub-model and wheel diameter, and what to check before replacing tires on an electric luxury SUV.
Tire Size & Fitment
What tire size fits a 2019 Audi Trucks e-tron Quattro?
The 2019 Audi Trucks e-tron Quattro uses three primary radial tire sizes: 255/55R19, 255/50R20, and 265/45R21. The correct size depends on the sub-model and the wheel package on the vehicle, so there is not one universal fitment across the full lineup.
The most important next step is confirming the wheel diameter actually installed on the vehicle. Premium Plus models use 19-inch or 20-inch fitments, Prestige models can use 19-inch, 20-inch, or 21-inch fitments, and Prestige Edition One uses the 21-inch setup.
What size rim does a 2019 Audi Trucks e-tron Quattro use?
The 2019 Audi Trucks e-tron Quattro uses three rim diameters depending on trim and tire fitment: 19-inch, 20-inch, and 21-inch. Those rim diameters correspond to the primary tire sizes 255/55R19, 255/50R20, and 265/45R21.
Rim diameter should be verified before ordering tires because each size is built for a specific wheel diameter and cannot simply be mixed with another. Checking the current wheel setup is especially important on used vehicles, where previous owners may have changed wheels or tire packages.
Do all 2019 Audi Trucks e-tron Quattro sub-models use the same tire size?
No, the 2019 Audi Trucks e-tron Quattro sub-models do not all use the same tire size. Premium Plus uses 255/55R19 or 255/50R20, Prestige can use 255/55R19, 255/50R20, or 265/45R21, and Prestige Edition One uses 265/45R21.
That variation means trim identification matters before choosing replacement tires. Even when two versions share part of the fitment range, the vehicle still needs the correct tire for the wheel diameter currently installed, so checking the sidewall and wheel together prevents costly ordering mistakes.
Choosing the Right Tire
What should I consider when choosing a 2019 Audi Trucks e-tron Quattro tire?
Start with the exact primary size already on the vehicle: 255/55R19, 255/50R20, or 265/45R21. Since the 2019 Audi Trucks e-tron Quattro is fully electric and uses multiple wheel diameters across its trims, the correct size and matching wheel fitment come before any other buying decision.
After size is confirmed, evaluate how the vehicle is used and whether the current wheel setup is original to the sub-model. A daily-driven e-tron, a lightly used family vehicle, and a carefully maintained luxury EV kept on a factory wheel package can all call for slightly different replacement priorities.
How do I choose between the available tire sizes for a 2019 Audi Trucks e-tron Quattro?
The available sizes are not interchangeable choices for the full model range. Each primary size belongs to a specific wheel diameter and trim combination, so the right choice is the size that matches the sub-model and wheel package already fitted to the 2019 Audi Trucks e-tron Quattro.
That means the decision usually starts in the driveway, not in the catalog. Check the tire sidewall, confirm whether the vehicle has 19-inch, 20-inch, or 21-inch wheels, and make sure the current setup has not been changed from its original trim-specific fitment before replacing anything.
How do I choose between the available 255/50R20, 255/55R19, and 265/45R21 tires for a 2019 Audi Trucks e-tron Quattro?
Choosing between 255/50R20, 255/55R19, and 265/45R21 is really about identifying which one belongs on the vehicle rather than comparing them as alternatives. Each size is tied to a different wheel diameter, and the 2019 Audi Trucks e-tron Quattro uses those diameters across different trims and wheel packages.
Once the correct size is confirmed, look at tire condition, intended use, and whether the vehicle remains on its original wheels. That approach keeps the selection process grounded in correct fitment and helps avoid buying a tire that matches the model name but not the actual wheel setup.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Audi Trucks e-tron Quattro restoration?
Yes, correct tire fitment still matters, even though the 2019 Audi Trucks e-tron Quattro is a modern electric vehicle rather than a traditional vintage restoration subject. The correct 255/55R19, 255/50R20, or 265/45R21 size helps preserve the intended relationship between the wheel package, ride height, and overall vehicle presentation.
Appearance on a late-classic or modern collector vehicle is often shaped by proportion as much as by styling. If the goal is to return the e-tron Quattro to a trim-appropriate look, match the proper wheel diameter and tire size first, then verify that previous wheel changes have not altered the vehicle’s visual balance.
How does tire size affect the appearance of a 2019 Audi Trucks e-tron Quattro?
Tire size has a noticeable effect on the stance of a 2019 Audi Trucks e-tron Quattro because its factory fitments are tied to 19-inch, 20-inch, and 21-inch wheel packages. Even though two of the primary sizes share nearly the same overall diameter, the wheel and sidewall proportions still change the vehicle’s visual character.
That matters if appearance is part of the ownership goal, especially on a premium electric SUV with large, design-forward wheels. Staying with the correct trim-specific size usually produces the most natural look, while any departure from the original wheel package should be checked carefully for both style and fitment implications.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Audi Trucks e-tron Quattro?
Yes, modifications can affect tire fitment on a 2019 Audi Trucks e-tron Quattro. Wheel changes, suspension lowering, offset differences, and aftermarket wheel packages can all alter how a 255/55R19, 255/50R20, or 265/45R21 tire sits in the wheel opening and how much clearance remains during steering and suspension travel.
That is why a replacement tire should match the actual wheel setup on the vehicle, not just the model name. If the e-tron Quattro has been modified, check wheel diameter, wheel width, clearance at full lock, and any signs of rubbing before assuming the original trim-based fitment still applies.
What should I inspect before driving a 2019 Audi Trucks e-tron Quattro on new tires?
Before driving a 2019 Audi Trucks e-tron Quattro on new tires, inspect wheel condition, confirm the tires match the installed rim diameter, and make sure inflation is set correctly for the vehicle’s use. It is also worth checking that each tire has proper seating and that no wheel or suspension issue is likely to affect wear.
A short initial road check can reveal vibration, pull, or unexpected clearance problems before they become larger issues. On a heavy electric SUV, it also makes sense to recheck pressure after the first few drives and look for any sign that the current wheel setup differs from the expected trim-level fitment.
How often should tires on a 2019 Audi Trucks e-tron Quattro be inspected?
Tires on a 2019 Audi Trucks e-tron Quattro should be inspected regularly, not just at replacement time. Frequent checks for pressure loss, uneven wear, cuts, bulges, and sidewall damage are especially useful on an EV, where vehicle weight and instant torque can make tire condition more important to day-to-day drivability.
A monthly visual inspection is a practical routine, with added attention before longer trips or after impact with potholes or road debris. Vehicles that sit for stretches should also be checked for flat spotting or pressure loss, since low-use patterns can hide tire issues until the vehicle returns to regular road use.
