The 2015 Audi Allroad blends wagon practicality with Audi’s upscale all-weather touring character, giving buyers a car that sits comfortably between luxury daily driver and enthusiast long-roof. Its raised stance and clean, modern proportions make wheel-and-tire fitment an important part of both appearance and road manners. For this exact model, tire choice centers on two radial sizes, 245/45R18 and 245/40R19, depending on sub-model and wheel setup. Available options stay firmly in modern blackwall performance-oriented radial territory, with differences in series, brand, and wheel-width compatibility rather than vintage-style construction. The key step is confirming the exact trim and wheel diameter before choosing the tire that best matches intended use.
Which Tire Size Is Right for The 2015 Audi Allroad
The 2015 Audi Allroad uses two primary tire sizes, and the correct choice depends first on confirming the exact sub-model and wheel diameter. Both fitments are radial tires, but one uses an 18-inch rim and the other a 19-inch rim. Premium models stay with 245/45R18, while Premium Plus and Prestige can use either size depending on the wheel setup already on the car.
245/45R18 is a modern metric radial size in which 245 identifies the nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2015 Audi Allroad, this size is one of the primary factory-style fitments and is used on every Premium model as well as some Premium Plus and Prestige cars. Available choices include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size makes sense when the car is already equipped with 18-inch wheels and you want to compare brand, series, and wheel-width compatibility within that setup.
245/40R19 is also a modern metric radial size, with the same 245-millimeter nominal width but a lower 40-series profile on a 19-inch wheel. On the 2015 Audi Allroad, this fitment appears on certain Premium Plus and Prestige configurations, so it is not shared across every sub-model. Product choices in this size center on BFGoodrich blackwall radials, including the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This size is the one to evaluate when the car already has 19-inch wheels and you want to stay with the proper rim diameter while comparing series and rim-width range.
Sub-model fitment is not completely uniform across the 2015 Audi Allroad range, so trim level alone does not always settle the tire decision. Premium uses one size, while Premium Plus and Prestige can appear with either 18-inch or 19-inch wheel fitment, making wheel confirmation just as important as trim identification.

If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2015 Audi Allroad Tires for Sale
Available 2015 Audi Allroad tire choices center on 245/45R18 and 245/40R19 blackwall radials from BFGoodrich and Nitto.

Owners shopping tires for a 2015 Audi Allroad usually need to sort out the exact size by trim and wheel diameter, then compare radial product choices by series, brand, and fitment details. These FAQs focus on those decisions, along with maintenance and road-use checks.
Tire Size & Fitment
What tire size fits a 2015 Audi Allroad?
The 2015 Audi Allroad uses either 245/45R18 or 245/40R19 tires. Both are radial fitments, but they do not use the same wheel diameter, so the correct size depends on the wheel package already on the car as well as the sub-model.
Premium models use 245/45R18, while Premium Plus and Prestige can appear with either size. The practical step is to confirm whether the car has 18-inch or 19-inch wheels before choosing tires, especially if the vehicle has had a wheel change at some point in its life.
What size rim does a 2015 Audi Allroad use?
A 2015 Audi Allroad uses either an 18-inch or 19-inch rim, depending on the tire size and wheel setup on the vehicle. The 245/45R18 tire matches an 18-inch wheel, while the 245/40R19 tire matches a 19-inch wheel.
That rim diameter decision comes first because tire sizes are not interchangeable across different wheel diameters. Checking the actual wheel on the car is especially important on Premium Plus and Prestige models, since those trims can use either fitment and may not still wear their original wheel package.
Do all 2015 Audi Allroad sub-models use the same tire size?
No, not all 2015 Audi Allroad sub-models use the same tire size. Premium models use 245/45R18, while Premium Plus and Prestige can use either 245/45R18 or 245/40R19 depending on how the vehicle is equipped.
That means trim level helps narrow the choice, but it does not replace a direct wheel check on every car. Looking at the tire sidewall or measuring wheel diameter is the safest way to confirm fitment before comparing products, especially on cars that may have been upgraded or changed by a previous owner.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 tire for a 2015 Audi Allroad?
Start with the correct size, then compare radial construction, tire series, rim-width range, and any stated load figure that matches the way the Allroad will be used. In 245/45R18, choices include BFGoodrich and Nitto blackwall tires across several performance-oriented series.
The real decision is less about basic fitment and more about matching the tire to the car’s current 18-inch wheel setup and intended driving style. Comparing wheel-width compatibility is worthwhile, and owners who want a sharper road feel may look at a different series than someone prioritizing more general all-season use.
What brands offer tires for the 2015 Audi Allroad?
The 2015 Audi Allroad has tire options from BFGoodrich and Nitto in the sizes covered here. BFGoodrich appears in both 18-inch and 19-inch fitments, while Nitto appears in 245/45R18.
Brand is only one part of the decision, since the available tires also differ by series, wheel-width specification, and load details where stated. A useful approach is to confirm the correct size first, then compare the tire’s series and dimensions against how the car is driven and which wheel package it currently wears.
What tire series are available for the 2015 Audi Allroad?
The 2015 Audi Allroad is covered by several tire series, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2. Not every series appears in both primary sizes, so the exact choice depends on whether the car uses 18-inch or 19-inch wheels.
Series selection helps separate an all-season-oriented option from tires that lean more toward a performance presentation. Once the correct size is confirmed, comparing the available series by wheel-width range, sidewall style, and any stated load specification gives a clearer picture of which tire best suits the car’s setup.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Audi Allroad?
A period-style approach for a 2015 Audi Allroad starts with keeping the correct primary size for the car’s actual wheel setup: 245/45R18 or 245/40R19. Since the available choices are modern blackwall radials, the appearance decision is less about vintage styling and more about preserving the clean, contemporary look the Allroad carried when new.
Keeping the proper wheel diameter and profile matters more than chasing novelty in a vehicle from this era. Owners concerned with showroom-era presentation should compare tire series carefully and verify the car’s current wheels against original trim-level equipment before making a cosmetic choice that changes the Allroad’s stance or visual balance.
Does correct tire fitment matter for a 2015 Audi Allroad restoration?
Yes, correct tire fitment matters on a 2015 Audi Allroad restoration because wheel diameter and sidewall profile strongly influence the car’s stance, proportions, and overall presentation. Using 245/45R18 on an 18-inch setup or 245/40R19 on a 19-inch setup helps keep the vehicle aligned with its intended visual character.
Fitment accuracy also affects practical details such as wheel compatibility and body clearance, so appearance and function go together here. Anyone aiming for a highly accurate restoration should verify the trim level and original wheel package through vehicle-specific documentation before choosing between the two primary sizes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Audi Allroad?
Yes, modifications can affect tire fitment on a 2015 Audi Allroad. Aftermarket wheels, altered wheel widths, suspension changes, lowering, or body modifications can all change how a 245/45R18 or 245/40R19 tire sits in the wheelwell and how much clearance it has in steering and suspension travel.
Even when the tire size itself is correct, a different wheel setup can change the real-world result. Checking actual wheel diameter, width, and clearance at full steering lock is smart before choosing tires, especially on Premium Plus or Prestige cars that may already have a different wheel package than they left with.
What should I inspect before driving a 2015 Audi Allroad on new tires?
Before driving a 2015 Audi Allroad on new tires, inspect the wheel condition, verify the installed size matches the wheel diameter, and confirm that inflation pressure is set correctly for the tire and vehicle use. It is also wise to look over alignment condition, valve stems, and any signs of rubbing or uneven wear.
A short check after the first miles is worthwhile because it can reveal air loss, clearance issues, or vibration that was not obvious during installation. Collector cars are not the only vehicles that benefit from this step; a modern wagon like the Allroad still deserves a careful once-over before regular road use resumes.
How often should tires on a 2015 Audi Allroad be inspected?
Tires on a 2015 Audi Allroad should be inspected regularly, not just when tread looks worn. A visual check for uneven wear, cuts, punctures, sidewall damage, and air loss is a good habit, and it becomes even more important if the car sees mixed weather use or spends long periods parked.
Routine inspection helps catch problems that can affect ride quality and fitment long before a tire actually fails. Looking at the tire sidewall also confirms that the car still has the expected 245/45R18 or 245/40R19 size, which is useful on vehicles that may have changed owners, wheels, or suspension parts over time.
