The 2019 Audi A4 allroad blends wagon utility with the road manners and refinement expected from Audi’s modern quattro era. Its raised stance and premium touring character make tire choice especially important, because the vehicle balances everyday comfort, all-weather confidence, and responsive handling in one package. The 2019 Audi A4 allroad uses a 245/45R18 radial tire on an 18-inch rim across the covered range. Available choices center on blackwall radial performance tires from BFGoodrich and Nitto in several distinct series. For most owners, the decision is less about sorting through multiple fitments and more about choosing the right tire character for road use, wheel compatibility, and overall driving feel.
Which Tire Size Is Right for The 2019 Audi A4 allroad
The 2019 Audi A4 allroad uses one primary tire size: 245/45R18 radial on an 18-inch rim. That same fitment carries across Premium, Premium Plus, and Prestige models, so the main decision is not which size fits the vehicle, but which tire within that size best matches the way the car is driven and the wheel setup actually on the vehicle.
A 245/45R18 size uses a 245-millimeter section width, a 45-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2019 Audi A4 allroad, this modern metric radial format suits the vehicle’s combination of touring comfort, all-weather use, and responsive road manners. Available choices in this size include blackwall radial tires from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. The practical comparison comes down to matching the tire’s series, load specification, and approved rim-width range to the wheels and driving character desired.
Tire fitment is straightforward across the covered 2019 Audi A4 allroad sub-models. Premium, Premium Plus, and Prestige all share the same 245/45R18 radial fitment, so sub-model identification matters less than confirming the actual wheels on the vehicle if anything has been changed.

The 2019 Audi A4 allroad Premium uses the same 245/45R18 radial tire fitment as the other covered trims. Tire selection therefore centers on choosing among the available blackwall radial options and confirming that the installed wheel width remains compatible with the tire being considered.
The 2019 Audi A4 allroad Premium Plus also uses 245/45R18 radial tires on an 18-inch rim. That keeps fitment simple, while still leaving room to compare tire series, load specification, and overall road-use character within the correct size.
The 2019 Audi A4 allroad Prestige shares the same 245/45R18 radial fitment found on the other covered sub-models. For this trim, the real choice is selecting the tire series that best suits the vehicle’s current wheel setup and the balance of comfort, response, and everyday use the owner wants.
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)

Tire Size & Fitment
What tire size fits a 2019 Audi A4 allroad?
The 2019 Audi A4 allroad uses a 245/45R18 radial tire. That fitment applies across the covered Premium, Premium Plus, and Prestige sub-models, giving the vehicle one consistent primary size rather than multiple trim-specific tire sizes.
That makes the buying decision simpler, but the size alone is not the whole story. It is still worth confirming that the vehicle is wearing its intended 18-inch wheels and that no aftermarket wheel, suspension, or ride-height changes have altered clearance or wheel-width requirements before choosing among available 245/45R18 tires.
What size rim does a 2019 Audi A4 allroad use?
The primary tire fitment for the 2019 Audi A4 allroad uses an 18-inch rim diameter. The 245/45R18 size is built around that 18-inch wheel, so matching the tire to the correct rim diameter is essential before comparing brands or tire series.
Rim diameter should be confirmed first, especially on a vehicle that may have seen wheel changes. After that, wheel width matters too, since available 245/45R18 products carry approved rim-width ranges around the mid-7-inch to 9-inch span, and staying within that range helps preserve proper tire shape and on-road behavior.
Do all 2019 Audi A4 allroad sub-models use the same tire size?
Yes. The covered 2019 Audi A4 allroad Premium, Premium Plus, and Prestige sub-models all use the same 245/45R18 radial tire size. There is no separate primary tire size among those trims, which keeps replacement selection more straightforward than on vehicles with trim-dependent fitment.
Even with shared trim fitment, it is still smart to inspect what is actually on the car before ordering tires. A previous owner may have installed different wheels, and that can change the wheel width or even the rim diameter, which affects whether a 245/45R18 tire remains the right choice for the current setup.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 tire for a 2019 Audi A4 allroad?
Start with the correct size and construction: 245/45R18 radial on an 18-inch rim. From there, compare each tire’s series, load specification where stated, approved rim-width range, and overall character, since the available options in this size are not all aimed at exactly the same driving feel.
A practical choice depends on how the A4 allroad is used. An owner focused on daily highway use may prioritize a different tire personality than someone who wants a sharper, more performance-oriented response, so it helps to balance wheel compatibility, expected road use, and the condition of the suspension and alignment.
What sidewall styles are available for 2019 Audi A4 allroad tires?
The available tires for the 2019 Audi A4 allroad’s 245/45R18 fitment use a blackwall sidewall style. That keeps the appearance clean and contemporary, which suits the car’s modern wagon profile without introducing the visual contrast of whitewalls, stripes, or raised white lettering.
Because the sidewall treatment stays consistent, the real visual and functional differences come from the tire series themselves rather than decorative sidewall styling. That makes it easier to narrow the decision around the brand, load specification, and intended driving character instead of trying to choose between multiple period-style appearance treatments.
What brands offer tires for the 2019 Audi A4 allroad?
245/45R18 tires for the 2019 Audi A4 allroad are available from BFGoodrich and Nitto. Within those brands, the choices include several distinct series, including BFGoodrich g-Force options and the Nitto NT555 G2, all in blackwall radial construction.
Brand alone should not be the only deciding factor. It helps to compare the individual tire series, approved rim-width range, stated load figure where available, and the kind of road use expected from the car, since two tires in the same size can still differ meaningfully in character and specification.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Audi A4 allroad restoration or preservation project?
Yes. Even though the 2019 Audi A4 allroad is a modern vehicle, correct tire fitment still matters for anyone preserving the car’s intended look and driving balance. The core fitment is 245/45R18 radial, and keeping that size maintains the proportions associated with the vehicle’s 18-inch wheel setup.
Preservation-minded owners should also pay attention to sidewall presentation and wheel compatibility. The available fitment centers on blackwall radials, so the appearance stays close to a contemporary factory-inspired look, while changes in wheel diameter, width, or offset can alter both stance and the way the tire sits in the wheel opening.
How does tire choice affect the appearance of a 2019 Audi A4 allroad?
On a 2019 Audi A4 allroad, tire choice affects appearance mostly through size accuracy, sidewall shape, and the visual character of the tire series rather than through vintage-style sidewall treatments. The available options stay within a blackwall radial presentation, which suits the vehicle’s clean, modern design language.
A tire that matches the intended 245/45R18 fitment helps preserve the right proportion between wheel, sidewall, and body. Owners chasing a well-kept original-style look should be cautious about changing wheel diameter or using a different profile, because even small visual shifts can make the car look less settled and less cohesive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Audi A4 allroad?
Yes. The 2019 Audi A4 allroad’s primary fitment is 245/45R18, but wheel and suspension changes can affect whether that size remains appropriate on the vehicle as it sits today. Aftermarket wheels may change width or offset, and ride-height changes can alter clearance at the fender, suspension, or steering components.
Any modified vehicle should be checked carefully before replacement tires are chosen. Measuring the actual wheel diameter and width, confirming turning and compression clearance, and looking for uneven wear patterns can prevent a tire choice that matches the original fitment on paper but no longer suits the current setup.
What should I inspect before driving a 2019 Audi A4 allroad on new tires?
Before driving on new tires, inspect the wheel condition, verify the rim diameter and width, and confirm that the 245/45R18 tires were mounted and inflated correctly. It is also smart to check for alignment issues, worn suspension components, and any rubbing marks that could point to a clearance problem.
A short road test should follow, paying attention to vibration, pulling, and steering feel. Rechecking air pressure after installation and looking over the tire sidewalls after the first few drives can catch problems early, especially on a vehicle that has sat for a while or has recently received wheel or suspension work.
How often should tires on a 2019 Audi A4 allroad be inspected?
Tires on a 2019 Audi A4 allroad should be inspected regularly, not just at replacement time. Routine checks for pressure loss, uneven tread wear, cuts, bulges, and sidewall damage help catch problems before they affect road manners, ride quality, or tire life.
Cars that are driven infrequently deserve even closer attention, because age and storage conditions can harm a tire that still shows usable tread. Looking over the tires before longer trips, keeping inflation at the proper level, and watching for cracking or flat-spotting are especially worthwhile on a modern premium wagon that may alternate between daily use and longer parked periods.
