The 2025 Audi A4 allroad blends wagon versatility with Audi’s long-running allroad formula, giving buyers a car that sits between a conventional sport wagon and a light-duty crossover in both stance and purpose. Its tire fitment story is straightforward: every covered version uses a 245/45R18 radial on an 18-inch rim. That means the real decision is less about finding the right primary size and more about choosing the tire character within it, with available blackwall performance-oriented options from BFGoodrich and Nitto. For an allroad that sees daily driving, seasonal touring, or enthusiast use, wheel compatibility and the intended driving feel matter as much as the size itself.
Which Tire Size Is Right for The 2025 Audi A4 allroad
The 2025 Audi A4 allroad uses one primary tire size: 245/45R18, a radial fitment on an 18-inch rim. That same size carries across Premium, Premium Plus, and Prestige models, so the main choice is not between multiple factory fitments but between the available tires in that size, their performance character, and their wheel-width compatibility.
245/45R18 is a metric radial size in which 245 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2025 Audi A4 allroad, this modern radial format suits the vehicle’s contemporary chassis, braking, and road manners. Available options in this size come from BFGoodrich and Nitto, all in blackwall form, with series including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. Choosing within this size comes down to matching the tire’s intended character to the wheel setup and how the allroad is actually driven.
Tire fitment is consistent across the covered 2025 Audi A4 allroad sub-models, which simplifies the first step in the buying process. Premium, Premium Plus, and Prestige all use the same primary tire size, so selection is more about tire type and wheel compatibility than trim-specific sizing differences.

2025 Audi A4 allroad Premium
The 2025 Audi A4 allroad Premium uses the same 245/45R18 radial fitment as the other covered trims. That keeps tire selection focused on choosing among the available blackwall radial options and confirming the wheel setup remains within the tire’s intended rim-width range.
The 2025 Audi A4 allroad Premium Plus shares the 245/45R18 radial size used across the model range. With trim-level size changes out of the equation, the key comparison becomes tire series, load specification, and whether the current wheels match the tire’s approved width range.
The 2025 Audi A4 allroad Prestige also uses a 245/45R18 radial on an 18-inch rim. That means the selection process centers on the available tire options in that size, along with checking wheel width and clearance if the vehicle has been altered from its original wheel or suspension setup.
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 2025 Audi A4 allroad?
The 2025 Audi A4 allroad uses a 245/45R18 tire size. This is a modern metric radial fitment, and it is the primary size used across Premium, Premium Plus, and Prestige versions covered here.
That consistency makes size selection simple, but the vehicle still needs the correct 18-inch wheel and a compatible wheel width for the tire chosen. If the car has aftermarket wheels, suspension changes, or a nonstandard setup, confirm wheel width and clearance before assuming any 245/45R18 tire will suit the vehicle the same way.
What size rim does a 2025 Audi A4 allroad use?
The 2025 Audi A4 allroad uses an 18-inch rim with its 245/45R18 tire fitment. The tire size itself confirms that wheel diameter, and the available products in this fitment are also built for 18-inch applications.
Wheel diameter is only part of the equation, so it helps to verify wheel width as well before selecting a tire. The available 245/45R18 products are intended for widths in the 7.5- to 9-inch range, making that check especially important if the allroad is wearing replacement wheels rather than the wheels originally fitted to the car.
Do all 2025 Audi A4 allroad sub-models use the same tire size?
Yes. Premium, Premium Plus, and Prestige versions of the 2025 Audi A4 allroad all use the same 245/45R18 radial tire size. There is no trim-specific split in primary tire sizing among those covered sub-models.
That shared fitment simplifies the process because the main decision is not identifying a different trim-based size. Attention can shift to comparing tire series, load figures where stated, and wheel-width suitability, while also checking whether the vehicle still has its original wheel and suspension configuration or has been modified since new.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 tire for a 2025 Audi A4 allroad?
Start with the confirmed 245/45R18 size, 18-inch wheel diameter, and radial construction used by the 2025 Audi A4 allroad. From there, compare the available tire series, sidewall treatment, load specification where stated, and the approved rim-width range for each option.
The best choice depends on how the allroad is used day to day and whether its wheels remain stock or have been changed. A careful comparison should include wheel width, the tire’s intended character, and any fitment limits tied to the product, rather than treating every tire in the same size as identical.
What sidewall styles are available for 2025 Audi A4 allroad tires?
The available 245/45R18 tires for the 2025 Audi A4 allroad are offered in blackwall form. That creates a uniform modern appearance across the current choices in this fitment rather than presenting a mix of whitewall, stripe, or raised-letter sidewall treatments.
Because the sidewall style stays consistent, the more meaningful visual and functional differences come from the tire series themselves and the overall stance of the tire on the wheel. Buyers comparing options should pay closer attention to wheel-width compatibility, load details, and the intended use of the vehicle than to appearance variations in sidewall treatment.
What brands offer tires for the 2025 Audi A4 allroad?
BFGoodrich and Nitto both offer tires in the 245/45R18 size used on the 2025 Audi A4 allroad. Within those brands, the available choices include several g-Force series from BFGoodrich and the NT555 G2 from Nitto.
Brand alone should not be the only deciding factor, because the available products also differ by tire series, stated load capacity in some listings, and approved rim-width range. A better approach is to compare each tire as a complete fitment choice for the car’s wheel setup and the kind of driving the allroad is expected to handle.
Restoration & Appearance
Does correct tire fitment matter for a 2025 Audi A4 allroad restoration or preservation-minded build?
Yes. Even on a modern vehicle like the 2025 Audi A4 allroad, correct tire fitment affects stance, wheel compatibility, and the overall impression of a well-kept or preservation-minded car. The proper starting point is the 245/45R18 radial size used across the covered trims.
Appearance on this vehicle is less about vintage sidewall styling and more about keeping the proportions and wheel relationship appropriate to the car. Buyers aiming for an original-style presentation should verify that wheel diameter and width remain appropriate, especially if the allroad has received aftermarket wheels or other visual modifications.
How does tire construction affect the appearance of a preserved 2025 Audi A4 allroad?
The 2025 Audi A4 allroad uses radial construction, so appearance differences come from the specific tire chosen rather than from a bias-ply-versus-radial decision. In this fitment, the available options are all blackwall radials, which keeps the overall look contemporary and consistent with the vehicle’s era.
Visual changes are more likely to come from tread character, sidewall shape on the wheel, and how the tire sits within the wheel opening. Anyone trying to maintain a clean, factory-inspired presentation should keep the 245/45R18 size intact and confirm that the wheel width and offset have not altered the car’s intended proportions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Audi A4 allroad?
Yes. A 2025 Audi A4 allroad may still use 245/45R18 tires after modifications, but wheel changes, altered offset, lowering, or suspension revisions can all affect how that size fits in practice. Tire size alone does not account for every clearance issue.
The safest approach is to confirm wheel diameter, wheel width, and available clearance at the fender, suspension, and steering points before selecting a replacement tire. That becomes especially important when the car no longer sits at standard ride height or uses aftermarket wheels that position the tire differently than the original setup.
What should I inspect before driving a 2025 Audi A4 allroad on new tires?
Inspect wheel condition, confirm the wheels are the proper 18-inch diameter, and make sure the selected 245/45R18 tires suit the actual wheel width on the vehicle. It also helps to check inflation, valve stems, lug torque, and general clearance around the tire once mounted.
A short visual inspection after installation can prevent avoidable problems. Look for rubbing at full steering lock, uneven spacing near the fenders, and any signs that a previous wheel or suspension change altered the fitment. After the first miles, recheck pressure and give the tires another quick inspection for settling or contact marks.
How often should tires on a 2025 Audi A4 allroad be inspected?
Tires on a 2025 Audi A4 allroad should be inspected regularly rather than only at replacement time. A quick routine check for pressure loss, tread wear, cuts, bulges, and sidewall damage helps catch issues early, especially on a vehicle that sees mixed city, highway, and seasonal driving.
Longer intervals between inspections can allow minor wear or damage to become a larger fitment or safety concern. It is smart to give the tires a closer look before a longer trip, after pothole impacts, and anytime the steering feel changes, the vehicle pulls, or a wheel or suspension component has recently been serviced.
