The 2025 Audi Trucks Q5 PHEV blends modern luxury crossover packaging with plug-in hybrid capability, making tire fitment a practical part of both appearance and everyday road manners. Owners shopping for this exact model are usually balancing a clean late-model presentation with the right wheel-and-tire setup for the vehicle already in the driveway. This Q5 PHEV uses radial tire fitments in either 235/55R19 or 255/45R20, so the first step is confirming which wheel diameter the vehicle carries. From there, the choice centers on the exact size, available sidewall treatments, and whether the priority is a straightforward modern look or a more distinctive visual style.
Which Tire Size Is Right for The 2025 Audi Trucks Q5 PHEV
The 2025 Audi Trucks Q5 PHEV uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. Some sub-models can use either size, while others are tied specifically to the 20-inch setup, so the first step is confirming the exact sub-model and whether the vehicle is on 19-inch or 20-inch wheels 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 2025 Audi Trucks Q5 PHEV, this size represents the 19-inch wheel fitment and keeps the buyer focused on matching the correct wheel setup before anything else. The size itself follows a familiar modern metric radial format, which makes it easier to compare with current replacement standards. Choosing this size starts with verifying that the vehicle actually wears 19-inch wheels, especially if it has been optioned differently or changed from its original wheel package.
Fit(s): Premium, Premium Plus, Premium Plus w/Air Suspension, Premium Plus w/Black Optic Pkg., Prestige, Prestige w/Air Suspension, and Prestige w/Black Optic Pkg.
Construction: Radial|Rim: 20 in
A 255/45R20 tire uses a 255-millimeter section width, a 45-series aspect ratio, radial construction, and a 20-inch rim diameter. For the 2025 Audi Trucks Q5 PHEV, this is the 20-inch fitment and it appears across several sub-model configurations, including versions tied specifically to that wheel size. Available products in this size include options from BFGoodrich, Nitto, and Pro-Trac, with sidewall choices that include Blackwall, raised white letter, and Redline across several tire series. This size is the one to evaluate when the vehicle already wears 20-inch wheels and the goal is to compare style and product character within that setup.
Tire fitment on the 2025 Audi Trucks Q5 PHEV varies by sub-model and wheel package rather than following one uniform setup across the range. Checking the exact trim name matters because some versions can use either 19-inch or 20-inch tires, while others are tied specifically to the 20-inch fitment.

2025 Audi Trucks Q5 PHEV Premium
The Premium sub-model can use either the 235/55R19 or 255/45R20 radial tire size, depending on the wheel package on the vehicle. Tire selection starts with confirming whether the Q5 PHEV has 19-inch or 20-inch wheels before comparing replacement options.
The Premium Plus sub-model also appears with either 235/55R19 or 255/45R20 radial fitment. That makes wheel diameter the key checkpoint, since the tire choice depends on the actual 19-inch or 20-inch setup installed on the vehicle.

Tire Size & Fitment
What tire size fits a 2025 Audi Trucks Q5 PHEV?
The 2025 Audi Trucks Q5 PHEV uses two primary tire sizes: 235/55R19 and 255/45R20. Both are radial fitments, and the correct size depends on the vehicle's exact sub-model and wheel package rather than one universal tire setup across the entire range.
The practical first step is checking the vehicle's installed wheel diameter and trim configuration. Some Q5 PHEV sub-models can use either size, while others are tied specifically to the 20-inch fitment, so a replacement tire should match the wheel on the vehicle instead of being chosen by model name alone.
What size rim does a 2025 Audi Trucks Q5 PHEV use?
A 2025 Audi Trucks Q5 PHEV uses either a 19-inch or 20-inch rim, depending on sub-model and wheel setup. The 235/55R19 size fits a 19-inch rim, while the 255/45R20 size fits a 20-inch rim.
Wheel diameter is the most important checkpoint before buying tires for this vehicle because the two primary sizes are not interchangeable across rim diameters. Looking at the sidewall on the current tire or confirming the wheel stamping helps prevent ordering a 19-inch tire for a Q5 PHEV that is actually running the 20-inch package.
Why does the 2025 Audi Trucks Q5 PHEV have more than one tire size?
More than one tire size appears on the 2025 Audi Trucks Q5 PHEV because different sub-models and wheel packages use different fitments. Some versions can be equipped with either 235/55R19 or 255/45R20, while certain air suspension and Black Optic configurations use the 255/45R20 size specifically.
That means the correct tire is tied to the actual configuration in front of you, not just the model badge. Confirming the exact sub-model and measuring against the installed wheel diameter keeps the replacement process straightforward and helps avoid choosing a tire that matches the vehicle name but not the wheel package.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2025 Audi Trucks Q5 PHEV?
Start with the basics: the tire must be the correct 255/45R20 size for a Q5 PHEV equipped with 20-inch wheels. From there, compare construction, sidewall appearance, tire series, rim-width compatibility, and any load or service details shown for the specific product.
This size includes several product personalities rather than one uniform choice. Some buyers want a straightforward Blackwall look, while others may prefer raised white letter or Redline styling, so the best decision usually comes from balancing wheel compatibility, visual preference, and how the vehicle will actually be driven.
What sidewall styles are available for 2025 Audi Trucks Q5 PHEV tires?
Among the available 255/45R20 products for the 2025 Audi Trucks Q5 PHEV, sidewall styles include Blackwall, RWL, and Redline. RWL refers to raised white letter styling, which gives a more distinctive visual treatment than a plain black sidewall.
Sidewall style does not change the need to match the correct tire size and wheel diameter, but it can change the vehicle's overall presentation. A Blackwall keeps a late-model appearance, while RWL or Redline introduces a more expressive look, so the choice often comes down to whether the Q5 PHEV is being kept understated or given extra visual character.
What brands offer tires for the 2025 Audi Trucks Q5 PHEV?
In the available 255/45R20 fitment for the 2025 Audi Trucks Q5 PHEV, brands include BFGoodrich, Nitto, and Pro-Trac. Those choices also span several tire series, so brand and series often work together when comparing products rather than acting as separate decisions.
A useful way to narrow the field is to compare each option by size match, sidewall treatment, and wheel compatibility first. Once those basics line up, the remaining differences in tire series and presentation make it easier to choose a tire that suits the vehicle's look and the kind of road use it will see.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Audi Trucks Q5 PHEV?
Yes, modifications can affect tire fitment on a 2025 Audi Trucks Q5 PHEV. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change the clearances that a 235/55R19 or 255/45R20 tire sees even when the size itself is correct for a stock configuration.
That is why the wheel currently on the vehicle matters as much as the model name. Checking actual wheel diameter, width, and surrounding clearance at the fender, suspension, and steering range helps avoid surprises, especially on a Q5 PHEV that no longer sits exactly as it left the factory.
What should I inspect before driving a 2025 Audi Trucks Q5 PHEV on new tires?
Before road use, inspect the wheel and tire combination for the correct size, proper inflation, secure valve stems, and any visible signs of shipping or mounting damage. It is also worth checking that the tire beads are seated properly and that nothing rubs at normal ride height or during steering travel.
A short, careful test drive can confirm that the Q5 PHEV tracks cleanly and has no interference under braking, turning, or suspension movement. Rechecking pressure and looking over the tires again after the first miles is a sensible follow-up step, particularly when the vehicle has optional wheels or prior suspension changes.
What should I check before a longer drive in a 2025 Audi Trucks Q5 PHEV?
Before a longer trip, confirm that the Q5 PHEV is on the correct tire size for its wheel package and that all four tires show even condition, proper pressure, and no cuts, bulges, or unusual tread wear. The spare situation, if applicable, also deserves attention before leaving home.
Longer drives put more emphasis on consistency across the full set, so uneven wear or a slow air-loss issue is worth addressing early. Looking over the wheels for damage and checking that the suspension and alignment feel normal can help the vehicle get the full benefit of a fresh tire setup.
