Audi Allroad Tires

Audi Allroad models from 2013 through 2016 use two tire sizes: 245/45R18 and 245/40R19. The 245/45R18 size fits 18-inch wheels, while the 245/40R19 size fits 19-inch wheels. Both are metric radial sizes, and both appear across the full 2013 to 2016 production span rather than being limited to early or late years.

That means model year alone does not identify the correct tire for every Audi Allroad. The practical way to choose is to verify the wheel diameter on the car, then match the size stamped on the current tire or listed on the vehicle placard. If wheels have ever been changed, the actual wheel on the car matters more than assumptions tied to the year.

On an Audi Allroad, 245/45R18 means the tire is 245 millimeters wide, has a sidewall height equal to 45 percent of that width, uses radial construction, and fits an 18-inch wheel. This is a modern metric radial size. The final number, 18, is the wheel diameter and must match the wheel exactly.

Understanding that code helps prevent one of the most common mistakes on optioned cars: choosing the right width but the wrong wheel diameter. Audi Allroad also used a 19-inch alternative in the same years, so a tire with the wrong final number will not fit the wheel. Read the full size code on the existing tire and confirm it against the wheel before making a change.

A 2014 Audi Allroad has two tire sizes listed because that model year used more than one wheel-and-tire configuration. The two sizes are 245/45R18 and 245/40R19, which correspond to 18-inch and 19-inch wheels. This is a wheel-package split rather than a change in tire construction or a midyear diameter change.

For an owner, that means the correct tire is determined by the actual wheel fitted to the car, not simply by the badge on the tailgate or the calendar year. If the car was bought used, verify whether it still carries its original wheel package. Measuring the wheel or reading the current tire sidewall is the quickest way to separate the 18-inch setup from the 19-inch setup.

Audi Allroad models in this 2013 to 2016 group use either 18-inch or 19-inch rim diameters. The 245/45R18 size fits an 18-inch rim, and the 245/40R19 size fits a 19-inch rim. Both rim diameters were used during the same production years, so there is no single wheel diameter for every Audi Allroad in this range.

That matters because rim diameter is the first fitment fact to confirm before comparing tread pattern, brand, or performance category. A 19-inch tire cannot be mounted on an 18-inch wheel, and the reverse is equally true. If the car has aftermarket wheels or a previous owner changed packages, inspect the wheel and current tire rather than relying only on a registration record.

A 2015 Audi Allroad can use either 245/45R18 or 245/40R19, so the correct tire size depends on the wheel package fitted to that specific car. The quickest confirmation is the size molded into the current tire sidewall, followed by the wheel diameter itself. An 18-inch wheel takes 245/45R18, and a 19-inch wheel takes 245/40R19.

Once the size is confirmed, compare the tire’s wheel-width compatibility to the wheel on the car. The listed 18-inch products suit rims roughly 7.5 to 9.0 inches wide, while the 19-inch products suit rims roughly 8.0 to 9.5 inches wide. That extra check is worthwhile on any Audi Allroad that may have seen wheel changes or enthusiast modifications.

The listed Audi Allroad tires are all blackwall designs. That applies to both available sizes, 245/45R18 and 245/40R19, and across both listed brands. There are no alternate period-style whitewall or specialty sidewall treatments in this fitment group.

That keeps the selection process straightforward for a modern Audi Allroad because the decision comes down to size, wheel diameter, and the tire series rather than appearance-driven sidewall choices. Buyers aiming to preserve the original modern touring look of the car will generally find blackwall appropriate. Focus your comparison on wheel diameter, intended use, and the behavior you want from the tire.

The available Audi Allroad tires here come from BFGoodrich and Nitto. BFGoodrich appears across both the 18-inch and 19-inch sizes, while Nitto is listed in the 245/45R18 size. All of the products in this fitment group are radial tires.

Brand choice is only useful after the wheel diameter and tire size are confirmed. Once that is settled, compare the available series within the correct size and think about how the Audi Allroad will be used, whether that is fair-weather touring, occasional spirited driving, or mostly seasonal mileage. Staying inside the correct size range matters more than changing brands.

Audi Allroad tires in this group are offered in several radial series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. These are all modern radial performance-oriented series rather than vintage-style bias-ply or specialty collector constructions. The main differences are the individual tire families within the available 18-inch and 19-inch sizes.

For an Audi Allroad owner, that means the first decision is fitment and the second is driving character. After confirming whether the car needs 245/45R18 or 245/40R19, compare the series available in that size instead of trying to force a preferred model onto the wrong wheel. This approach keeps the selection process orderly and avoids chasing tread preferences before basic fitment is settled.

An Audi Allroad should be stored on a clean, dry surface away from direct sunlight, ozone sources, and major temperature swings when the tires are fitted. Keep the tires inflated to an appropriate stored pressure for the vehicle and avoid letting the full weight sit in one position for very long periods. For a modern radial tire, long stationary storage can still create flat-spotting or stress from underinflation.

If the Audi Allroad will sit for weeks or months, move it occasionally or place it on tire cradles to spread the load. A quick visual check before and after storage helps catch sidewall damage, embedded objects, or pressure loss early. Storage habits matter even on newer collector-era wagons because low mileage often means more time parked than driving.

Tires on an Audi Allroad should be inspected before any long drive and at regular intervals even if the car sees only occasional use. Check inflation pressure, tread wear, sidewall condition, and any signs of impact damage or uneven wear. Radial performance tires can look acceptable at a glance while still showing age-related cracking or wear patterns that deserve attention.

Collector-minded owners often put few miles on an Audi Allroad, which makes scheduled inspections more important, not less. A tire can age while parked, and an alignment or suspension issue can show up long before tread depth becomes low. Building a habit of monthly inspections and a closer seasonal check is a sensible way to catch problems before the car goes back on the road.

Tires on an Audi Allroad should be replaced when age, cracking, impact damage, bulges, persistent vibration, or uneven wear make them questionable, even if tread depth still appears usable. Tread alone is not the whole story on a low-mileage enthusiast car. A radial tire that has hardened with age may no longer perform as intended in braking, wet conditions, or sustained highway driving.

The practical rule is to judge the tire as a complete component, not just a wear surface. If an Audi Allroad has sat for long periods, have the tires examined carefully before regular road use, especially if they are several years old or their service history is unclear. Replacing aging tires before they become visibly severe is usually cheaper than dealing with damage from a failure.

The listed Audi Allroad tires are modern radial road tires in the correct 18-inch and 19-inch fitments used on 2013 to 2016 models, so they are intended for public-road use when matched to the correct wheel diameter and kept in sound condition. Safety depends on correct size selection, proper inflation, wheel condition, and the overall mechanical state of the car. A tire that fits the wheel correctly is only one part of roadworthiness.

Before regular driving, confirm the Audi Allroad is on the correct 245/45R18 or 245/40R19 size for its wheels and inspect for age, damage, and uneven wear. Any used or newly acquired car deserves a full baseline inspection, especially if its wheel package may have been changed. Road safety improves when tire choice, alignment, and suspension condition are treated as one system.

Before driving an Audi Allroad, check that all four tires match the wheel diameter fitted to the car, that inflation pressures are appropriate, and that there is no visible damage, cracking, puncture, or abnormal wear. Also look for mismatched sizes front to rear if the car has been modified. Since both 18-inch and 19-inch fitments exist for these years, confirming the actual installed size is especially important.

A short walk-around can prevent most tire-related surprises. Read the full size code on each tire, inspect the sidewalls, and pay attention to how the car feels during the first few miles. If the Audi Allroad pulls, vibrates, or feels harsh in a way that seems new, stop and investigate before continuing at speed.

A reasonable speed for an Audi Allroad depends on the exact tire fitted, its condition, inflation, and the operating environment, not simply the model name. The listed tires are modern radial products with performance-oriented sizing, but any tire’s safe real-world use still depends on age, wear, and whether it is the correct size for the wheel. An older or neglected tire should not be treated as if it were freshly installed.

For practical road use, drive within the condition of the tire and the condition of the car rather than assuming all fitted tires can safely deliver the same result. If the Audi Allroad is newly purchased or has been sitting, start with moderate speeds until the tires, alignment, and suspension are evaluated. Confidence should come from inspection and condition, not from the vehicle’s original performance image.
