2020 Audi A4 allroad Tires

The 2020 Audi A4 allroad uses a 245/45R18 radial tire. That size appears across Premium, Premium Plus, and Prestige models, so the core fitment is consistent throughout the covered lineup rather than split by trim.

That makes the buying decision more about choosing the right tire within 245/45R18 than sorting through multiple factory sizes. It is still smart to confirm the actual wheel setup on the vehicle, especially if it has aftermarket wheels, seasonal wheel packages, or previous fitment changes that could affect width, clearance, or overall compatibility.

The primary tire fitment for the 2020 Audi A4 allroad is built around an 18-inch rim. The 245/45R18 size uses that 18-inch wheel diameter across the covered Premium, Premium Plus, and Prestige sub-models.

Wheel diameter is only part of the fitment picture, so the next check is wheel width and overall setup. Available 245/45R18 products are intended for modern rim-width ranges, and that matters if the car has replacement wheels, spacers, or a non-stock package that changes how the tire sits or clears the suspension and fenders.

Yes. Premium, Premium Plus, and Prestige versions of the 2020 Audi A4 allroad all use the same 245/45R18 radial tire size. There is no covered sub-model split that requires choosing between different primary sizes.

That consistency simplifies replacement shopping, but it does not remove the need to verify the vehicle as it sits today. A used allroad may have alternate wheels, changed offsets, or different tire brands installed previously, so it helps to confirm the wheel dimensions and compare the new tire’s intended rim-width range before making a final choice.

Start with the correct size, 245/45R18, and make sure the tire is intended for an 18-inch wheel with a compatible rim-width range. Within that size, the available choices differ by brand, tire series, weight, and load-related specifications rather than by sidewall style, since the visible options here are Blackwall radials.

The best comparison approach is to match the tire to how the allroad is actually used. A vehicle that sees everyday road miles, enthusiastic driving, or seasonal wheel changes may call for a different product emphasis, so wheel width, load capacity details, and the car’s present setup deserve as much attention as the size itself.

The available 245/45R18 fitment choices for the 2020 Audi A4 allroad include BFGoodrich and Nitto. BFGoodrich appears in several g-Force series options, while Nitto is represented by the NT555 G2, giving the buyer more than one brand path within the same primary size.

Brand alone should not decide the purchase. It helps to compare each tire’s series, supported rim-width range, weight, and any stated load information against the actual wheels on the car and the kind of road use it sees, rather than assuming every tire in the same nominal size will suit every setup equally well.

Within the 245/45R18 size, the 2020 Audi A4 allroad has options in BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, Nitto NT555 G2, and BFGoodrich g-Force Phenom T/A. Those series give the buyer several modern radial choices within the correct fitment.

Comparing series is useful because it separates one product’s character from another even when the size stays the same. Once the 245/45R18 fitment is confirmed, the next step is to compare wheel-width compatibility, weight, and load-related specifications so the selected tire suits both the car’s hardware and the owner’s intended driving pattern.

A 2020 Audi A4 allroad is a modern vehicle, so a period-style look usually means staying with the correct 245/45R18 size and choosing a tire that preserves a clean contemporary appearance. In the covered product range, that means comparing modern radial offerings rather than looking for vintage-style bias-ply or wide-whitewall treatments.

Appearance should still be balanced against wheel compatibility and intended use. Since the available options are Blackwall tires in several series, the visual decision is subtler than on a classic car, and the more important check becomes whether the selected tire suits the actual 18-inch wheels and the allroad’s current ride-height and clearance setup.

Yes. Even on a newer collector-leaning wagon like the 2020 Audi A4 allroad, correct tire fitment matters because it affects stance, wheel presentation, and how finished the vehicle feels after refurbishment. Staying with the proper 245/45R18 size keeps the visual proportions in line with the model’s intended wheel-and-tire relationship.

Refurbishment work often includes replacement wheels, suspension service, or cosmetic updates, and those changes can alter fitment more than expected. Keeping the correct size as the baseline makes comparison easier, but final selection should still account for actual wheel width, any offset change, and whether the tire clears properly at normal ride height and steering angle.

Yes. A 2020 Audi A4 allroad may start with a straightforward 245/45R18 fitment, but aftermarket wheels, changed offsets, spacers, suspension lowering, or other setup changes can alter how that size sits on the car. Even when the tire size remains the same, the actual fit can change.

That is why a modified allroad should be checked as a complete wheel-and-tire package rather than by size alone. Steering clearance, fender room, and wheel width all deserve a look before replacing tires, especially if the vehicle has been personalized or if its current setup differs from the standard 18-inch arrangement.

Before road use, inspect tire pressure, confirm the tires match the wheel diameter and intended rim-width range, and look over the wheels for damage or obvious mounting issues. It also helps to check tread seating visually and make sure there is no contact with suspension parts or bodywork at normal ride height.

A short, careful shakedown drive is a useful next step. Pay attention to vibration, pulling, unusual noise, or any sign of rubbing during turns, then recheck pressure and visible clearances afterward. That process is especially worthwhile if the allroad has replacement wheels or if the previous tires differed in brand, construction details, or wear pattern.

Regular maintenance starts with keeping the 245/45R18 tires properly inflated, inspecting tread and sidewalls, and watching for cuts, bulges, cracking, or uneven wear. Even on a modern vehicle, tire age and condition matter, particularly if the allroad sees limited mileage or spends long periods parked between drives.

Storage conditions also make a difference. Cleaner, drier spaces away from prolonged sunlight and ozone sources help preserve a tire’s condition, while routine pressure checks help catch slow air loss before it becomes a larger issue. On any collector-minded or lightly used allroad, visual inspection should be part of every pre-drive routine, not just annual service.
