2024 Audi A4 Quattro Tires

The 2024 Audi A4 Quattro uses three primary tire sizes: 225/50R17, 245/40R18, and 245/35R19. All three are radial sizes, and the correct one depends on the exact sub-model and wheel package. Some Premium models use either 17-inch or 18-inch fitments, while certain Premium Plus and Prestige configurations can use either 18-inch or 19-inch tires.

The safest starting point is the wheel diameter currently on the car, followed by the exact trim and horsepower configuration. Matching the installed wheel size is essential, because a 17-inch, 18-inch, or 19-inch tire is built for a different rim diameter even when the vehicle name stays the same.

A 2024 Audi A4 Quattro can use 17-inch, 18-inch, or 19-inch rims depending on the tire size fitted to the car. The corresponding tire sizes are 225/50R17 for 17-inch rims, 245/40R18 for 18-inch rims, and 245/35R19 for 19-inch rims. Each tire size is designed around its own wheel diameter.

Rim diameter should be confirmed before anything else, because it determines which tire size family even belongs on the car. After that, wheel width also deserves attention, especially when comparing among different product lines, since some 18-inch and 19-inch tires carry more specific rim-width recommendations than others.

The 2024 Audi A4 Quattro has more than one tire size because fitment varies by sub-model and wheel package. Across the range, Audi A4 Quattro configurations can use 225/50R17, 245/40R18, or 245/35R19. That means the car name alone is not enough to choose a tire without also confirming trim and installed wheel diameter.

This matters most on Premium, Premium Plus, and Prestige versions that may overlap in name but differ in wheel setup. A buyer looking at 245/40R18 and 245/35R19 options should verify the actual wheel on the vehicle, while 225/50R17 applies only where the 17-inch package is present.

Start with the exact 245/40R18 size, then compare how each tire differs in intended use, rim-width specification, sidewall style, and tire series. This size has the broadest selection for the 2024 Audi A4 Quattro, with choices from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac across blackwall, redline, and RWL designs.

That wider product spread means the decision is less about basic fitment and more about how the car is used and how it should look. A daily-driven sedan, a style-focused build, and a more specialized performance setup may point toward very different 245/40R18 options even though the tire size itself remains the same.

Sidewall style depends on the tire size chosen for the 2024 Audi A4 Quattro. Blackwall is available across all three primary sizes, while the 245/40R18 fitment also includes redline and RWL options through the Pro-Trac Street Pro III line. That makes the 18-inch setup the main choice for buyers who want something other than a plain black sidewall.

Appearance should still follow fitment, not the other way around. A redline or raised white letter tire may change the visual character of the car, but it only makes sense if the vehicle already uses the 245/40R18 size and the wheel setup matches the tire’s intended rim range.

Tires for the 2024 Audi A4 Quattro are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. BFGoodrich and Nitto appear across multiple fitments, while M&H Racemaster and Pro-Trac are present in 245/40R18. The available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, NT555 G2, Street Pro III, and Drag Radial.

Brand choice should be filtered through the exact size on the car first, because not every brand spans every wheel diameter. Once the correct fitment is confirmed, compare the tire series, sidewall presentation, and any rim-width or load details that matter for the way the A4 Quattro is driven.

A period-style approach on a 2024 Audi A4 Quattro usually means staying with the exact tire size and wheel diameter used on the car, then choosing a sidewall and tire series that support the look you want. Blackwall is available in all three primary sizes, while 245/40R18 also opens the door to redline and RWL presentation.

Because this is a contemporary luxury sport sedan rather than an older restoration platform, appearance choices are more about visual preference than historical authenticity. Keeping the original wheel diameter and correct size relationship is the cleaner way to preserve the car’s stance than forcing a sidewall treatment onto the wrong fitment.

On the 2024 Audi A4 Quattro, tire construction is straightforward because the primary fitments are all radial. That means appearance differences come less from bias-ply-versus-radial construction and more from profile, wheel diameter, sidewall style, and tire series. A 17-inch setup, 18-inch setup, and 19-inch setup each present the car differently even before brand is considered.

Visual balance often comes from preserving the wheel-and-tire combination the car was built around rather than mixing sizes casually. On this platform, the most noticeable appearance changes usually come from choosing blackwall, redline, or RWL in the correct size, especially within the 245/40R18 fitment.

Yes, modifications can affect tire fitment on a 2024 Audi A4 Quattro even when the tire size itself is correct on paper. Aftermarket wheels, changes in wheel width, offset differences, lowered suspension, or body modifications can all change how a 225/50R17, 245/40R18, or 245/35R19 tire sits in the wheel opening and clears during steering or suspension travel.

A modified car should be checked as it actually sits, not only by model year and trim. Tire-to-fender clearance, inner suspension clearance, and the wheel’s true diameter and width all matter, especially with lower-profile 18-inch and 19-inch combinations where small setup changes can have a bigger effect.

Before driving a 2024 Audi A4 Quattro on new tires, inspect wheel condition, confirm the installed tire size matches the wheel diameter, and make sure inflation pressure is set correctly for the application. It also helps to look over the suspension, alignment condition, and any signs of rubbing or contact around the fenders and inner wheel wells.

A brief road check after installation is worthwhile, especially if the car has 18-inch or 19-inch wheels or has seen any wheel changes. Listen for rubbing at full steering lock, watch for vibration, and recheck pressure after the first few drives so the new tires settle into normal use properly.

Tires on a 2024 Audi A4 Quattro should be inspected regularly, not just when tread looks low. Routine checks should include pressure, tread wear pattern, cuts, bulges, and any sidewall damage. On a car with multiple possible wheel packages, it is also smart to confirm that all four tires remain the same size and construction intended for that setup.

Inspection becomes even more important if the car is driven seasonally, parked for long periods, or uses a more specialized tire series. Uneven wear can point to alignment or suspension issues, while repeated air loss or visible damage should be addressed before the next longer drive rather than after a problem develops.
