The 2018 Audi R8 sits in the modern exotic category, combining everyday drivability with supercar proportions, a mid-engine layout, and the sharp wheel-and-tire stance that defines the model’s look and response. Tire fitment on this car is a staggered radial setup, with different front and rear sizes and either 19-inch or 20-inch wheel diameters depending on the configuration. That makes the first decision less about brand loyalty and more about confirming the exact wheel package already on the car. Once that is settled, the real comparison comes down to size-specific product choices, sidewall appearance, and matching the tire to the car’s intended street use and presentation.
Which Tire Size Is Right for The 2018 Audi R8
The 2018 Audi R8 uses four primary tire sizes across a staggered front-and-rear setup, and the correct combination depends first on whether the car is running 19-inch or 20-inch wheels. Front sizes pair with rear sizes by wheel diameter, so confirming the exact wheel package on the car is the key first step before comparing brands, series, or sidewall treatments.
Fit(s): Base Front, Plus Front, Plus Spyder Front, RWS Front, and Spyder Front
Construction: Radial|Rim: 20 in
This size reads as a 245-millimeter section width, 30-series aspect ratio, radial construction, and 20-inch rim diameter. On the 2018 Audi R8, it serves as a front tire size in the 20-inch staggered setup, where a low-profile radial helps preserve the car’s sharp steering feel and modern supercar stance. Available product selection in this size centers on a blackwall Nitto NT555 G2. Choosing this size starts with confirming that the car is actually equipped with the 20-inch front wheel package rather than the 19-inch setup.
Fit(s): Base Front, Plus Front, Plus Spyder Front, RWS Front, and Spyder Front
Construction: Radial|Rim: 19 in
This size uses a 245-millimeter section width, a 35-series profile, radial construction, and a 19-inch rim diameter. It is one of the front fitments for the 2018 Audi R8 and belongs with the 19-inch staggered arrangement rather than the 20-inch package. Product choices in this size include BFGoodrich and Nitto blackwall radials across the g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. This is the size to evaluate when the car has 19-inch front wheels and the goal is comparing tire character within the correct front fitment.
Fit(s): Base Rear, Plus Rear, Plus Spyder Rear, RWS Rear, and Spyder Rear
Construction: Radial|Rim: 19 in
This size indicates a 295-millimeter section width, 35-series profile, radial construction, and a 19-inch rim diameter. On the 2018 Audi R8, it is a rear tire size used with the 19-inch staggered combination, so it should be matched to the corresponding 19-inch front fitment rather than mixed casually with a different wheel package. The available product choice here is a blackwall Nitto NT555 G2. This rear size matters most when confirming that the car remains on its proper 19-inch setup with the expected front-to-rear stagger intact.
Fit(s): Base Rear, Plus Rear, Plus Spyder Rear, RWS Rear, and Spyder Rear
Construction: Radial|Rim: 20 in
This size means a 305-millimeter section width, 30-series aspect ratio, radial construction, and a 20-inch rim diameter. It serves as the rear tire size in the 20-inch staggered setup for the 2018 Audi R8, where width and profile are part of the car’s aggressive modern footprint. Product options include a Nitto NT555 G2 blackwall and Pro-Trac Street Pro III versions with raised white letter and redline sidewall treatments. This size is the one to compare when the car has 20-inch rear wheels and appearance is part of the buying decision.
Sub-model fitment on the 2018 Audi R8 is straightforward in one sense and exacting in another: the covered versions share the same front size pair and the same rear size pair, but the car still depends on the correct staggered wheel package. Checking whether the car has 19-inch or 20-inch wheels remains essential before choosing tires.

2018 Audi R8 Base Front
The 2018 Audi R8 Base Front uses the same two front size choices seen across the rest of the range, tied to either a 19-inch or 20-inch wheel setup. Tire selection here starts with confirming wheel diameter, then comparing the available radial options in the correct front size.
The 2018 Audi R8 Base Rear follows the same rear stagger as the other covered versions, with one rear size for the 19-inch setup and another for the 20-inch setup. That means the rear tire should be chosen as part of the full wheel package, not as a standalone size decision.
The 2018 Audi R8 Plus Front shares the same two front radial sizes used elsewhere in the lineup. The practical decision is verifying whether the car is on 19-inch or 20-inch front wheels, then choosing among the available tire series within that exact fitment.
The 2018 Audi R8 Plus Rear uses the same rear tire-size pattern as the other configurations, with separate rear sizes tied to 19-inch and 20-inch wheels. Matching the rear tire to the existing wheel diameter and proper front-and-rear stagger is the key selection point.
The 2018 Audi R8 Plus Spyder Front carries the same front fitment choices as the coupe-based variants, depending on the wheel package already on the car. Tire shopping here is mainly about confirming 19-inch versus 20-inch wheels and selecting the right radial in that front size.
The 2018 Audi R8 Plus Spyder Rear uses the same rear size pattern as the rest of the 2018 R8 range covered here. Rear tire choice should stay tied to the car’s actual wheel diameter and the matching staggered front setup for proper fitment balance.
The 2018 Audi R8 RWS Front follows the same front sizing approach as the other sub-models, with one 19-inch front size and one 20-inch front size. The important step is confirming the wheel already on the car, then comparing radial options in that exact front fitment.
The 2018 Audi R8 RWS Rear shares the same rear tire choices as the other listed R8 configurations, split between 19-inch and 20-inch wheel packages. Tire selection is therefore about preserving the correct stagger and choosing a rear tire that matches the wheel diameter already in place.
The 2018 Audi R8 Spyder Front uses the same front fitment choices as the rest of the covered lineup, tied directly to the car’s 19-inch or 20-inch wheels. Once wheel diameter is confirmed, the decision shifts to brand and tire series within the correct front size.
The 2018 Audi R8 Spyder Rear uses the same rear sizing pattern found across the model family, with distinct rear sizes for 19-inch and 20-inch setups. The best way to approach tire selection is to verify the current wheel package and keep the correct front-to-rear pairing intact.

Tire Size & Fitment
What tire size fits a 2018 Audi R8?
The 2018 Audi R8 uses a staggered radial setup with four primary sizes: 245/35R19 and 295/35R19 for the 19-inch package, or 245/30R20 and 305/30R20 for the 20-inch package. Front and rear tires are different sizes, so the car does not use one universal tire size at all four corners.
The practical step is confirming which wheel package is actually on the car before choosing tires. A 19-inch front tire belongs with the 19-inch rear tire, and the same pairing logic applies to the 20-inch setup. Cars with aftermarket wheels or changed suspension should also be checked carefully before ordering replacements.
What size rim does a 2018 Audi R8 use?
A 2018 Audi R8 uses either 19-inch or 20-inch rims, depending on the tire size combination on the car. The 245/35R19 and 295/35R19 sizes mount on 19-inch wheels, while the 245/30R20 and 305/30R20 sizes mount on 20-inch wheels.
Rim diameter is the first detail to verify because the front and rear fitments are tied to a matched staggered package. Looking only at the sidewall on one tire can lead to a mistake, especially on a car that may have had wheel changes. Check both front and rear sizes and confirm the full set before selecting replacements.
Why does the 2018 Audi R8 have more than one tire size?
The 2018 Audi R8 has more than one tire size because it uses a staggered layout and was fitted with either a 19-inch or 20-inch wheel package. The front tires are narrower than the rears, and each wheel diameter has its own matching front-and-rear size combination.
That means the right tire choice depends less on trim name and more on the wheel setup currently on the car. Owners should confirm whether the R8 is still on its original-style stagger or has been modified with different wheels. Keeping the correct front and rear pairing helps avoid avoidable fitment and clearance issues.
Choosing the Right Tire
What should I consider when choosing a 2018 Audi R8 tire?
Start with the correct front-and-rear size combination and the correct wheel diameter, since the 2018 Audi R8 uses either a 19-inch staggered setup or a 20-inch staggered setup. All of the available choices here are radial tires, so the next comparison points are tire series, sidewall style, and any size-specific product details.
A useful way to narrow the choice is to think about how the car is used and how the tires should look on it. Some sizes offer only one option, while others provide more room to compare brands or appearance. Wheel width, suspension changes, and previous modifications should also be checked before settling on a final tire.
What sidewall styles are available for 2018 Audi R8 tires?
Sidewall style depends on the tire size chosen for the 2018 Audi R8. Blackwall options are available across the fitment range, while the 305/30R20 rear size also appears with raised white letter and redline sidewall treatments through the Pro-Trac Street Pro III line.
That makes sidewall appearance more of a factor on some rear 20-inch setups than on the front sizes or the 19-inch rear fitment. Owners looking for a more understated modern look may stay with blackwall, while those wanting a stronger visual statement can compare the alternate 305/30R20 presentations after confirming the car uses that rear size.
What brands offer tires for the 2018 Audi R8?
Tires for the 2018 Audi R8 are available here from BFGoodrich, Nitto, and Pro-Trac, depending on the exact size. Nitto appears across several of the listed fitments, BFGoodrich is available in 245/35R19, and Pro-Trac is offered in the 305/30R20 rear size.
Brand choice should always come after the correct fitment is confirmed. Some sizes give only one brand option, while others allow a closer comparison between series and sidewall style. It also helps to review details such as rim-width guidance where it is provided, especially when the car may not be on its original wheel setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Audi R8?
Yes. A 2018 Audi R8 already uses a low-profile staggered setup, so wheel changes, altered offsets, suspension lowering, or body modifications can affect how a replacement tire fits. Even when the sidewall size looks correct, the overall package on the car may not match a standard 19-inch or 20-inch arrangement anymore.
A careful check should include front and rear wheel diameter, wheel width, tire clearance at full steering lock, and clearance around suspension and fender edges. Cars with aftermarket wheels deserve extra attention because a size that belongs on an R8 in general still needs to suit the exact wheel and chassis setup on that specific car.
What should I inspect before driving a 2018 Audi R8 on new tires?
Before putting a 2018 Audi R8 back into regular road use on new tires, inspect wheel condition, confirm that the front and rear sizes are correctly paired, and make sure inflation is set appropriately for the tires being used. It also helps to look over alignment-related wear patterns on the old tires before they are removed.
A short follow-up inspection after the first miles is worthwhile on a performance car with short sidewalls and staggered fitment. Check for any rubbing, air loss, or uneven settling, and make sure the steering feels clean and centered. If the car has been stored or recently modified, a broader suspension and wheel check is sensible as well.
How often should tires on a 2018 Audi R8 be inspected?
Tires on a 2018 Audi R8 should be inspected regularly, especially because the car uses low-profile front and rear sizes that can be more sensitive to pressure loss, curb damage, and irregular wear. A visual check before drives and a more deliberate inspection at routine service intervals is a sensible habit.
Owners should look for cuts, bulges, cracking, tread wear differences from side to side, and any sign that front and rear tires have been mismatched. Collector or low-mileage cars deserve the same attention, since age and storage conditions matter even when mileage stays low. Keeping pressures stable and the tires clean also helps protect the fitment.
