The 2019 Audi RS3 sits in a modern performance niche where compact Audi sport sedans deliver serious pace, all-weather capability, and a highly tuned chassis in a relatively understated package. Buyers looking at tires for this car are usually balancing sharp handling, correct staggered sizing, and the realities of road use on a low-profile 19-inch setup. The 2019 Audi RS3 uses radial tires in two primary sizes, 235/35R19 and 255/30R19, so identifying front-versus-rear fitment matters first. Current choices in the covered fitment center on Blackwall radial performance tires from Nitto and BFGoodrich. The right selection depends on maintaining the correct axle position, wheel compatibility, and the driving character you want from the car.
Which Tire Size Is Right for The 2019 Audi RS3
The 2019 Audi RS3 uses two primary tire sizes, and both are radial tires built for 19-inch rims. Because this fitment is split by position, the first step is confirming whether you are replacing a front or rear tire rather than treating the car as a single-size setup. Once that is clear, the decision shifts to selecting the right performance tire within the correct size, sidewall style, and wheel-width range where applicable.
The 235/35R19 size uses modern metric sizing: 235 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2019 Audi RS3, this is part of the car's staggered radial setup, so it needs to stay in the correct axle position. Available choices in this size include Blackwall performance tires from Nitto and BFGoodrich, with series differences that matter to buyers comparing brand and specification details. This size should be evaluated with the actual wheel width and placement on the car in mind before selecting a tire.
The 255/30R19 size is also a modern metric radial, with 255 indicating nominal section width in millimeters, 30 showing a very low-profile sidewall, and 19 identifying the wheel diameter. On the 2019 Audi RS3, this size serves a specific position in the staggered 19-inch fitment rather than acting as a universal four-corner size. Its low-profile format suits the car's performance-focused setup, where maintaining the intended size relationship across the vehicle is important. This is the size to review carefully when replacing tires on the axle that requires the wider, shorter-sidewall fitment.
Tire fitment on the 2019 Audi RS3 is straightforward once the wheel position is identified, because the covered sub-model entries split the car by size rather than by a different construction type. Checking the exact front or rear application matters before ordering, since the RS3 uses different 19-inch radial sizes across the setup.

2019 Audi RS3 Base
The 2019 Audi RS3 Base uses the 235/35R19 radial size in the covered fitment. That makes tire selection less about changing dimensions and more about matching the correct 19-inch performance tire to the wheel and intended driving use.
The 2019 Audi RS3 Base Front uses the 255/30R19 radial size as its position-specific fitment. Front-position replacement should focus on keeping that exact low-profile 19-inch size in place and confirming the wheel setup before choosing a tire.
The 2019 Audi RS3 Base Rear uses the 235/35R19 radial size in the covered fitment. Rear tire replacement in this position should stay centered on that size while comparing available performance tire options and checking wheel-width compatibility.
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)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2019 Audi RS3?
The 2019 Audi RS3 uses two primary tire sizes: 235/35R19 and 255/30R19. Both are radial tires built for 19-inch wheels, and the fitment is position-specific rather than a single four-corner size for the whole car.
That means the first step is identifying whether the tire is for the front or rear position on your RS3. Matching the exact size to the correct wheel location helps preserve the intended staggered setup, and it is worth confirming the actual wheel on the car if it has ever been rotated, replaced, or modified.
What size rim does a 2019 Audi RS3 use?
The covered tire fitments for the 2019 Audi RS3 use a 19-inch rim diameter. Both primary sizes, 235/35R19 and 255/30R19, are built around that same 19-inch wheel diameter even though the section width and profile differ.
Rim diameter is only part of the fitment picture, so it is still important to verify wheel width before selecting a replacement tire. One 235/35R19 option is matched to an 8 to 9.5 inch rim-width range, and that kind of detail matters on a performance sedan with low-profile tires.
Why does the 2019 Audi RS3 have more than one tire size?
The 2019 Audi RS3 uses more than one tire size because its fitment is split by position. The covered setup pairs 235/35R19 with 255/30R19, so the car is not treated as a same-size front-and-rear application.
For tire replacement, that means a buyer should not assume that any 19-inch tire on the car belongs at every corner. Confirming the axle position, the exact wheel dimensions, and the size already mounted on the vehicle helps avoid ordering the wrong low-profile performance tire for the RS3's staggered arrangement.
Choosing the Right Tire
What should I consider when choosing a 235/35R19 tire for a 2019 Audi RS3?
Start with the correct size, wheel position, and radial construction. On the 2019 Audi RS3, 235/35R19 is part of a staggered 19-inch setup, so the goal is to match the exact application first and then compare the available tire series and brand options within that size.
From there, look at details such as rim-width compatibility, load specification where stated, tire weight, and the kind of road use the car sees most often. A low-profile performance tire that suits the actual wheel and intended use will be a better choice than selecting by brand name alone.
What sidewall styles are available for 2019 Audi RS3 tires?
The available 235/35R19 products for the 2019 Audi RS3 use a Blackwall sidewall style. That keeps the appearance straightforward and performance-oriented, which suits a modern sport sedan without introducing whitewall, redline, or other vintage-style presentation choices.
Even with a single sidewall style, there is still a real choice to make between tire series and brand. For most RS3 owners, sidewall appearance will be less important than confirming the correct axle size, checking wheel width, and selecting a radial performance tire that matches how the car is driven.
What brands offer tires for the 2019 Audi RS3?
The currently covered 235/35R19 options for the 2019 Audi RS3 include Nitto and BFGoodrich. Those choices give buyers more than one brand to compare within the correct radial size rather than forcing the decision into a single product line.
Brand should be only one part of the decision. It still makes sense to compare the specific tire series, wheel-width specification where given, load details where stated, and the actual position on the car, especially since the RS3 uses a staggered setup with different front and rear tire sizes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Audi RS3?
Yes, modifications can affect tire fitment on a 2019 Audi RS3 even when the replacement tire matches one of the original 19-inch sizes. Changes such as aftermarket wheels, altered wheel width, suspension lowering, spacer use, or body modifications can all influence how a low-profile tire sits and clears.
A tire that works on one RS3 may need a closer check on another if the car no longer has its original wheel and suspension setup. Before installation, confirm wheel diameter, wheel width, axle position, and clearance at full steering lock and normal suspension movement.
What should I inspect before driving a 2019 Audi RS3 on new tires?
Before driving on new tires, inspect the installation itself and the surrounding wheel area. Make sure the 2019 Audi RS3 has the correct front and rear sizes in the correct positions, and check that the tires seat properly, hold air, and show no contact with suspension or fender surfaces.
It also helps to verify tire pressure, look over the wheels for damage, and confirm that the car tracks normally once back on the road. Any sign of rubbing, vibration, unusual wear, or rapid air loss should be addressed immediately rather than treated as normal break-in behavior.
What should I check before a longer drive in a 2019 Audi RS3?
Before a longer drive, check tire pressure, tread condition, sidewall condition, and overall visual consistency across all four corners of the 2019 Audi RS3. On a car with low-profile 19-inch tires and staggered sizing, it is especially important to confirm that each axle is carrying the correct size.
A longer trip is also a good time to inspect for cuts, bulges, uneven wear, and any signs of rubbing that might not be obvious during short local use. Looking over the wheels, checking for slow air loss, and verifying that nothing has changed after recent service can prevent avoidable problems on the road.
