2024 Audi Tire Fitment Guide

2024 Audi vehicles use 23 tire sizes across 24 model cores: 225/45R17, 225/40R18, 225/50R17, 245/40R18, 245/35R19, 245/45R18, 255/35R19, 245/45R19, 255/40R20, 245/45R20, 255/35R21, 255/45R19, 265/35R21, 265/40R20, 285/40R20, 305/30R21, 265/30R19, 265/35R19, 275/30R20, 275/35R21, 285/30R22, 235/35R19, and 265/30R20. Rim diameters span 17 through 22 inches, and active product coverage includes rim-width guidance for many 17-, 18-, 19-, and 20-inch sizes such as 7.0 to 8.5 inches for 225/45R17 and 8.5 to 10.0 inches for 255/35R19.

That range means a buyer cannot choose a 2024 Audi tire by year and make alone. A3, A4, A5, A6, A7, A8, S, RS, and e-tron GT models all use different size strategies, and several RS and GT applications use staggered combinations with one size at the front and another at the rear. Checking the exact model and the wheel diameter on the car is the fastest way to narrow the field correctly.

On a 2024 Audi, 225/45R17 is a metric radial size. The 225 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. In the 2024 Audi range, this size appears on A3 and A3 Quattro models and is available in blackwall radial form from BFGoodrich and Nitto with W speed ratings up to 118 mph.

That coding matters because a 225/45R17 is not interchangeable with a 225/40R18 even though both may appear on closely related Audi compact models. The sidewall height and wheel diameter change together, and the correct match depends on which wheel package is actually on the car. Confirming the wheel size first prevents a very common mistake when comparing A3-family fitments.

No. 2024 Audi uses model-specific tire sizing across the lineup, with compact A3 models beginning at 17 inches, midsize and luxury cars spreading through 18-, 19-, 20-, and 21-inch packages, and RS6 Avant and RS7 Sportback reaching 22 inches. Some sizes are shared by related models, such as 255/35R19 across A5 Quattro, A5 Sportback, S4, S5, and S5 Sportback, but no single size fits the entire 2024 Audi range.

The practical takeaway is that exact model identification comes before brand or tread choice. That is especially important on RS3, RS e-tron GT, and e-tron GT applications, where multiple sizes may appear on the same car depending on axle position. If the sidewall marking on the car and the wheel diameter do not match the product you are considering, stop there and verify fitment first.

Current 2024 Audi tire coverage here is centered on blackwall radial tires. Blackwall construction appears across the active sizes with products from BFGoodrich, Nitto, and M&H Racemaster, including compact 17-inch applications such as 225/45R17, sport sedan sizes like 245/40R18 and 255/35R19, and larger 20-inch fitments such as 245/45R20. No whitewall or vintage-style sidewall treatments appear in these sizes.

That is exactly what most modern Audi buyers expect, since the 2024 lineup is contemporary in both styling and tire design. The main visual difference tends to come from tire profile and overall section width rather than sidewall ornamentation. If maintaining a factory-modern appearance matters, choosing the correct size and wheel diameter will have a bigger effect than searching for alternate sidewall styles.

2024 Audi coverage here comes from BFGoodrich, Nitto, and M&H Racemaster. BFGoodrich appears across the widest spread of active sizes, Nitto covers many of the same modern metric fitments, and M&H Racemaster appears in 245/40R18 with a drag-oriented radial option. Brand availability changes by size, so smaller A3-family fitments, midsize A4 and A5 sizes, and larger A6 allroad or GT sizes do not all draw from the same exact mix.

The useful approach is to pick the correct size first, then compare which brands are actually offered in that fitment. On some sizes, such as 255/40R20 or 275/30R20, the field is much narrower than it is in more common 17-, 18-, or 19-inch sizes. That can influence your final choice more than brand loyalty alone, especially on less common Audi performance applications.

For 2024 Audi applications where both are available, BFGoodrich g-Force Comp 2 A/S and Nitto NT555 G2 often share the same basic size and blackwall radial construction but differ in some technical details. In 225/45R17, for example, the BFGoodrich tire fits 7.0 to 8.5-inch rims at 24 pounds, while the Nitto also fits a 7.0 to 8.5-inch range and weighs about 22.78 pounds, with a 1,477-pound load figure at 50 psi. Similar side-by-side comparisons also appear in sizes like 225/40R18, 245/45R18, and 245/45R20.

That means the decision should come down to the exact size you need and the product details that matter most for your car, such as load rating, rim-width compatibility, or speed rating within that size. It is worth comparing the sidewall marking and technical specifications tire by tire rather than assuming two performance radials in the same nominal size are interchangeable in every respect.

Rim-width guidance on 2024 Audi tires varies by size. Examples include 225/45R17 at 7.0 to 8.5 inches, 225/40R18 at 7.5 to 9.0 inches, 225/50R17 at 6.0 to 8.0 inches, 245/40R18 at 8.0 to 9.5 inches, 245/45R18 at 7.5 to 9.0 inches, 255/35R19 at 8.5 to 10.0 inches, 245/45R19 at 7.5 to 9.0 inches, and 255/40R20 at 8.5 to 10.0 inches. Some products carry a fixed or narrower recommendation, such as the M&H 245/40R18 at 8.5 inches.

Those ranges are one reason Audi tire fitment should be checked against the actual wheel, not just the sidewall size. A nominally correct tire can still be a poor match if the wheel falls outside the approved width range for that product. This matters most on low-profile 19- and 20-inch applications, where sidewall shape and wheel protection can change noticeably with rim width.

2024 Audi tire applications here are modern radial fitments, and tube status varies by product in some sizes rather than staying uniform across the entire range. Some products explicitly show TL markings, such as BFGoodrich g-Force Comp 2 A/S in 245/40R18 and 245/45R20, indicating tubeless construction, while many others do not carry a tube marker in the size line. There are no TT tube-type markings in the active 2024 Audi product coverage.

That makes it important to check the exact sidewall marking and product specification for the tire you plan to use, especially if you are replacing only part of a set. On modern Audi wheels, tubeless fitment is the norm, but the safest approach is still to confirm the product’s own marking and make sure the wheel condition, valve stem, and sealing surfaces are appropriate.

No single original 2024 Audi wheel can be assumed to work with all 2024 Audi tire sizes because the lineup spans 17-, 18-, 19-, 20-, 21-, and 22-inch diameters. Even within one model family, such as A4, A5, A8, or the RS lines, Audi uses multiple wheel diameters and sometimes multiple widths or staggered front-to-rear arrangements. A 19-inch wheel cannot accept a 20-inch tire, and a 20-inch wheel cannot accept a 21-inch tire.

The right question is whether your exact factory wheel matches the exact tire size on your car. Confirm the wheel diameter first, then compare the tire’s approved rim-width range to the actual wheel width. That is especially important on RS and GT models, where wider rear tires and very short sidewalls leave less room for guesswork than on more conventional sedan applications.

A 2024 Audi should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that can age rubber prematurely. Keep the tires clean, maintain inflation, and move the car periodically so the same section of tread is not supporting the vehicle for months at a time. Low-profile radial tires generally resist flat-spotting better than older bias-ply designs, but long static storage can still affect ride quality and casing shape.

If the car will sit for an extended season, many owners either overinflate slightly within safe limits for storage or place the vehicle on stands after confirming proper support points. That is particularly sensible on RS, S, and GT models with wider tires and shorter sidewalls, since these combinations can be more sensitive to long-term pressure loss or deformation during inactivity.

On a 2024 Audi, tire age matters as much as tread depth, especially on lower-mileage enthusiast or secondary vehicles. A good rule is to evaluate tires closely once they reach roughly five to seven years of age and to treat around ten years as a serious replacement threshold regardless of mileage. The DOT date code on the tire sidewall is the best way to confirm age, and it should be read along with overall condition, storage history, and any visible cracking or hardening.

Modern performance-oriented Audi sizes can still look usable while aging out structurally, particularly if the car is driven infrequently or stored outdoors. Wide, low-profile tires on S, RS, and GT models also tend to live harder lives because of heat cycles, alignment sensitivity, and heavier wheel packages. Age-based inspection is a more reliable guide than waiting for the tread alone to tell the story.

Tires on a 2024 Audi should be checked before every drive in a quick walk-around and inspected more thoroughly before any longer trip. Look for visible cuts, bulges, sidewall cracking, irregular shoulder wear, punctures, and signs of pressure loss. Low-profile Audi fitments can hide inner-edge wear until it becomes advanced, so periodic full inspections with the wheel turned or removed are worth the effort.

Monthly pressure checks are a minimum, and frequent checks are even more important on staggered RS and GT setups where front and rear sizes differ. If the steering feel changes, the car pulls, or one corner loses pressure repeatedly, inspect immediately rather than waiting for the next service interval. Catching a worn or damaged tire early is far less expensive than replacing a wheel or dealing with a roadside failure.

Yes, the active 2024 Audi tires here are modern radial products suitable for normal highway use when they are in good condition, correctly sized, and properly inflated. Many carry W speed ratings up to 118 mph, while some sizes also appear with Y ratings up to 186+ mph, including fitments such as 245/40R18, 245/45R18, 245/45R19, 245/45R20, 255/35R19, 265/35R19, and 235/35R19. Those ratings exceed normal U.S. highway speeds by a wide margin.

Real-world safety on a 2024 Audi depends just as much on alignment, inflation, brake condition, suspension health, and using the correct front and rear sizes as it does on the speed symbol molded into the tire. On modern Audi performance cars, a mismatched size or underinflated tire is a more immediate concern than whether the theoretical top-speed ceiling is high enough for ordinary road driving.

Inflation pressure for a 2024 Audi should follow the vehicle’s factory placard or owner’s manual first, because Audi sets pressure by model, axle load, and wheel package rather than by tire size alone. Tire load-and-pressure figures do appear on some products, such as 1,477 pounds at 50 psi for certain 225/45R17 and 225/50R17 applications, 1,764 pounds at 50 psi for some 245/45R18 products, and 1,929 pounds at 50 psi for a 245/45R20 application. Those are tire capacity references, not universal operating pressures for every 2024 Audi.

That distinction matters because two different Audi models can use similarly sized tires while needing different cold pressures. Use the car’s specified pressure for daily operation, then confirm the tire’s own maximum load and pressure marking if you are comparing products. Never transfer a pressure figure from one size or one Audi model to another simply because the dimensions look close.

Before a longer drive in a 2024 Audi, inspect all four tires and the spare if the car carries one. Check cold pressures, look for nails, cuts, sidewall bulges, uneven wear, and any cracking, and confirm that the front and rear sizes match the intended positions on staggered-fitment cars such as RS3, RS e-tron GT, and e-tron GT applications. Also make sure valve stems are in good condition and that no wheel has visible damage or a slow leak.

That tire check should be part of a broader readiness review on any higher-performance or luxury vehicle. Brakes, alignment feel, suspension noises, charging or fuel range, and roadside inflation equipment all matter when the car uses specialized low-profile sizes that may be harder to replace away from home. A few minutes of inspection can prevent an avoidable interruption on a trip.
