The 2015 Audi Trucks Q3 Quattro sits in the modern compact luxury crossover category, blending Audi all-wheel-drive character with a smaller footprint that still expects confident road manners and crisp response. Tire choice matters here because this Q3 Quattro uses two primary radial fitments, 235/50R18 and 255/40R19, tied to different wheel diameters. That means the first step is confirming whether the vehicle is on 18-inch or 19-inch wheels before comparing tires. From there, the decision shifts to tread character, sidewall style, and brand choice, with blackwall, redline, and raised white letter options available in several series. Owners should also account for any wheel changes or suspension modifications before selecting a replacement set.
Which Tire Size Is Right for The 2015 Audi Trucks Q3 Quattro
The 2015 Audi Trucks Q3 Quattro uses two primary tire sizes, and the correct one depends first on wheel diameter. Both Premium Plus and Prestige models can use either 235/50R18 or 255/40R19, so the key step is confirming whether the vehicle has 18-inch or 19-inch wheels before choosing a tire. Once that is settled, the decision becomes construction-compatible product selection, sidewall preference, and the character of the tire series you want on the vehicle.
255/40R19 is a metric radial size with a 255-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2015 Audi Trucks Q3 Quattro, this size applies to the 19-inch wheel configuration and represents a lower-profile alternative to the 18-inch setup. Product choices include BFGoodrich and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall styles available in multiple series. This is the size to evaluate when the vehicle is equipped with 19-inch wheels and the goal is matching that wheel diameter while comparing style and product details.
Tire fitment is straightforward across the covered 2015 Audi Trucks Q3 Quattro sub-models because both Premium Plus and Prestige can use the same two radial sizes. Checking the exact sub-model still helps, but wheel diameter is the more important detail when narrowing the correct tire choice.

2015 Audi Trucks Q3 Quattro Premium Plus
The 2015 Audi Trucks Q3 Quattro Premium Plus can use either of the two primary radial fitments for this model line, depending on whether it is equipped with 18-inch or 19-inch wheels. Tire selection therefore starts with wheel confirmation, then moves to comparing brands, series, and sidewall treatments within the matching size.
The 2015 Audi Trucks Q3 Quattro Prestige shares the same overall tire-fitment pattern, with both primary radial sizes used across the sub-model. That makes wheel diameter the deciding factor first, followed by product-level choices such as blackwall, redline, or raised white letter styling.
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 2015 Audi Trucks Q3 Quattro?
The 2015 Audi Trucks Q3 Quattro uses two primary tire sizes: 235/50R18 and 255/40R19. Both are radial fitments, and both Premium Plus and Prestige versions can use either size depending on the wheel package installed on the vehicle.
The practical difference is wheel diameter. A Q3 Quattro on 18-inch wheels needs the 235/50R18 fitment, while a vehicle on 19-inch wheels needs 255/40R19. Before choosing tires, confirm the actual wheel size on the vehicle, especially if it has changed hands or has been fitted with aftermarket wheels.
What size rim does a 2015 Audi Trucks Q3 Quattro use?
The 2015 Audi Trucks Q3 Quattro uses either an 18-inch or 19-inch rim, depending on which of its two primary tire sizes is on the vehicle. The 235/50R18 fitment uses an 18-inch rim, and the 255/40R19 fitment uses a 19-inch rim.
That rim diameter determines which tire size you can use, so it should be confirmed before comparing brands or sidewall styles. The easiest check is the size already molded into the tire sidewall, but the wheel itself should also be verified if the vehicle has had wheel swaps or a previous non-stock tire installation.
Do all 2015 Audi Trucks Q3 Quattro sub-models use the same tire size?
Premium Plus and Prestige versions of the 2015 Audi Trucks Q3 Quattro share the same overall fitment pattern, but that does not mean every vehicle uses the same tire size. Both sub-models can use 235/50R18 or 255/40R19, depending on wheel diameter.
That makes the wheel setup more important than the trim name when ordering replacement tires. Once the vehicle is confirmed to have either 18-inch or 19-inch wheels, the tire search becomes much simpler. It is still wise to inspect the current wheel and tire combination closely on any used or modified Q3 Quattro.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Audi Trucks Q3 Quattro?
Start with the correct primary size for the wheel on the vehicle: 235/50R18 for 18-inch wheels or 255/40R19 for 19-inch wheels. From there, compare construction details within the available radial offerings, plus brand, tire series, sidewall style, and any rim-width specification that applies to the product.
The best choice depends on how the Q3 Quattro is used and how you want it to look. Some owners will prefer a straightforward blackwall presentation, while others may want redline or raised white letter styling. It also helps to compare load figures and general tire dimensions when replacing a mixed or previously altered setup.
What sidewall styles are available for 2015 Audi Trucks Q3 Quattro tires?
Three sidewall presentations are available within the 2015 Audi Trucks Q3 Quattro tire selection: blackwall, redline, and RWL, which is raised white letter. These appear across both 235/50R18 and 255/40R19 fitments, depending on the specific product line.
Sidewall style does not change the basic fitment requirement, but it does affect how the vehicle presents visually. Blackwall keeps a contemporary appearance, while redline and raised white letter options create a more custom or enthusiast-oriented look. The right choice comes down to maintaining the vehicle’s current style while staying with the correct wheel diameter.
What brands offer tires for the 2015 Audi Trucks Q3 Quattro?
The 2015 Audi Trucks Q3 Quattro is served by BFGoodrich, Nitto, and Pro-Trac in its two primary sizes. Depending on the fitment, the available series include g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand comparison is most useful after the correct size is locked in. At that point, the differences are more about series character, sidewall treatment, and product specifications than basic fitment. Keeping the search within the correct 18-inch or 19-inch size prevents a lot of confusion when several similar performance-oriented options appear together.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Audi Trucks Q3 Quattro?
A period-style approach on a 2015 Audi Trucks Q3 Quattro usually starts with keeping the correct wheel diameter and primary tire size already used on the vehicle, then choosing a sidewall treatment that matches the look you want. That could mean a blackwall for a clean contemporary presentation or a more distinctive redline or raised white letter option.
Because this is a modern vehicle, appearance choices are more about style direction than formal restoration correctness. Matching the tire size to the wheel remains the non-negotiable step. Once that is confirmed, tire series and sidewall design become the tools for shaping a more understated, sporty, or custom visual effect.
How does tire construction affect the appearance of a restored 2015 Audi Trucks Q3 Quattro?
On the 2015 Audi Trucks Q3 Quattro, tire construction is straightforward because the primary fitments are radial. That means appearance differences come less from bias-ply versus radial construction and more from the chosen series, profile, and sidewall treatment within the correct 235/50R18 or 255/40R19 size.
Visual impact still matters. A blackwall keeps the Q3 restrained and modern, while redline or raised white letter versions create a stronger enthusiast statement. Owners trying to preserve a clean, model-appropriate look should compare sidewall style carefully and avoid letting appearance choices lead them away from the wheel diameter the vehicle actually uses.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Audi Trucks Q3 Quattro?
Yes. The 2015 Audi Trucks Q3 Quattro already uses two different wheel diameters, so aftermarket wheels, lowered suspension, spacer changes, or altered alignment settings can affect which tire size works properly on the vehicle. Even when the sidewall size appears close, wheel and clearance details still matter.
A modified Q3 Quattro should be checked for wheel width, tire-to-strut clearance, fender clearance, and steering travel before replacement tires are chosen. That is especially important when the vehicle has moved away from its original wheel setup. Matching the existing sidewall marking alone is not enough if the whole package has been changed.
What should I inspect before driving a 2015 Audi Trucks Q3 Quattro on new tires?
Before road use, inspect the wheel diameter and make sure the new tires match the correct 18-inch or 19-inch setup. Tire pressure, valve condition, visible bead seating, and any signs of rubbing should also be checked, along with a quick look at suspension and steering components that could affect how the tire sits.
A short, careful test drive helps confirm that the Q3 Quattro tracks properly and clears the body and suspension through normal steering movement. It is also smart to recheck inflation after the first drive. Any vibration, pulling, or contact marks should be addressed before the vehicle is put into regular service.
How often should tires on a 2015 Audi Trucks Q3 Quattro be inspected?
Tires on a 2015 Audi Trucks Q3 Quattro should be inspected routinely, not just when tread looks worn. Regular checks should include pressure, uneven wear, cuts, punctures, bulges, and sidewall damage, especially on a vehicle using lower-profile 255/40R19 tires where impact damage can be easier to overlook.
Inspection is also important after pothole strikes, curb contact, seasonal wheel changes, or any suspension work. Vehicles that are driven infrequently still need attention because age, storage conditions, and slow air loss can affect tire condition. A quick visual check before longer trips is a sensible habit even when mileage remains low.
