The 2011 Audi S5 sits in the modern grand-touring end of the performance coupe market, blending V8-era S-car character with sharp styling and everyday drivability. It appeals to buyers who want a German sport coupe or cabriolet that still feels substantial and refined on the road. Tire selection for the 2011 Audi S5 is refreshingly straightforward, as both the Base and Cabriolet use a 255/35R19 radial on a 19-inch rim. That simplicity shifts the decision toward tire series, load capability, and road-use priorities rather than basic fitment. For an S5 that is driven as intended, wheel condition, exact tire spec, and overall setup deserve close attention before replacement.
Which Tire Size Is Right for The 2011 Audi S5
The 2011 Audi S5 uses one primary tire size: 255/35R19, a metric radial fitted to a 19-inch rim. That same size is shared by the Base and Cabriolet, so the main choice is not between multiple fitments but between the available radial tire options, their series, and their intended road-use character.
255/35R19 is a modern metric radial size in which 255 identifies the nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 19 is the rim diameter in inches. On a 2011 Audi S5, this low-profile radial format supports the car’s contemporary performance-oriented wheel and tire package. Available choices in this size center on BFGoodrich blackwall tires across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. Choosing within 255/35R19 comes down to matching the tire’s specifications and character to the S5’s actual wheel setup and intended use.
Fitment is consistent across the covered 2011 Audi S5 sub-models, with the same primary tire size used on both versions. That makes selection simpler, but it is still worth confirming the car’s current wheels and overall setup before replacing tires.

2011 Audi S5 Base
The 2011 Audi S5 Base uses the same 255/35R19 radial fitment found across this model range. Tire selection is therefore more about choosing the right blackwall radial series and confirming wheel condition, width, and overall compatibility than sorting through multiple primary sizes.
The 2011 Audi S5 Cabriolet also uses the 255/35R19 radial size on a 19-inch rim. That keeps fitment straightforward, while still leaving room to compare available tire series, load-related specifications, and suitability for the car’s present wheel and suspension setup.
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 2011 Audi S5?
The 2011 Audi S5 uses a 255/35R19 tire size. This is the primary fitment for both the Base and Cabriolet, and it is a radial tire matched to a 19-inch rim.
That makes size selection fairly simple, but the work should not stop at the sidewall code. A replacement tire should still be checked against the actual wheel width on the car, overall wheel condition, and any changes made by a previous owner so the S5 keeps the intended balance of clearance, handling, and appearance.
What size rim does a 2011 Audi S5 use?
The 2011 Audi S5 uses a 19-inch rim with its 255/35R19 tire fitment. The available tires in this size are built around that 19-inch wheel diameter, so confirming the car still has the correct wheel diameter is an important first step.
Rim diameter should not be confused with rim width, which also matters when choosing among replacement tires. A car with aftermarket wheels may still be 19 inches in diameter but differ in width or offset, and those changes can affect sidewall shape, clearance, and how comfortably a specific 255/35R19 tire works on the vehicle.
Do all 2011 Audi S5 sub-models use the same tire size?
Yes. Both the 2011 Audi S5 Base and the 2011 Audi S5 Cabriolet use the same 255/35R19 radial tire size. There is no split in primary fitment between the covered sub-models here, which keeps replacement sizing straightforward.
Even with shared fitment, it is still smart to verify the exact wheel package currently on the car before purchasing tires. Collector ownership, curb damage, wheel replacement, or suspension changes can all affect what fits comfortably, so matching the tire size is only part of getting the S5 ready for reliable road use.
Choosing the Right Tire
What should I consider when choosing a 255/35R19 tire for a 2011 Audi S5?
Start with the correct size and construction: 255/35R19 radial on a 19-inch rim. From there, compare the available tire series, the wheel-width range each tire is designed to suit, and specification details such as load-related ratings and product weight where those differences matter to your intended use.
A 2011 Audi S5 places real demands on its tires, so the right choice depends on how the car is driven and how original its wheel setup remains. Looking closely at wheel width, clearance, and the car’s present suspension condition will help narrow the field more effectively than treating every 255/35R19 tire as the same.
What sidewall styles are available for 2011 Audi S5 tires?
The available 255/35R19 tires for the 2011 Audi S5 use a blackwall sidewall style. That gives the car a clean, contemporary appearance that suits the S5’s modern performance character without introducing a vintage sidewall treatment that would look out of place on this application.
Since sidewall style does not vary here, the real visual and functional comparison moves to tire series and specification details within the same blackwall presentation. Buyers who want to maintain a cohesive appearance should also consider wheel finish, ride height, and whether the car still carries its intended 19-inch performance-oriented setup.
What tire series are available for the 2011 Audi S5?
The 2011 Audi S5’s 255/35R19 fitment is available in several BFGoodrich series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. All are blackwall radials in the correct basic size, but they differ in series designation and related product specifications.
That means the buying decision is less about finding a size that fits and more about comparing how each series aligns with the car’s actual use. Looking at wheel-width suitability, load-related details, and the condition of the S5’s wheels and suspension will help determine which option makes the most sense for the car in front of you.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Audi S5?
A period-style approach for a 2011 Audi S5 still begins with the correct 255/35R19 radial size on a 19-inch rim. Since this is a modern performance-era vehicle rather than a vintage bias-ply application, the focus is on preserving the original overall look and stance rather than recreating a historic sidewall treatment.
Blackwall tires suit that goal best within the available options, and the final choice comes down to series and specification details rather than nostalgic styling cues. Owners pursuing exact showroom-era authenticity should compare the car’s current wheels and tire presentation with marque-specific references so appearance and fitment stay aligned.
Does correct tire fitment matter for a 2011 Audi S5 restoration?
Yes, correct tire fitment matters on a 2011 Audi S5 restoration because the 255/35R19 size is part of the car’s overall visual stance and intended driving character. A tire that departs from the proper size, profile, or wheel relationship can change how the finished car looks and feels.
That is especially important on a modern performance car where wheel-to-tire proportion is a major part of the design. Even if the car is not being restored for judged competition, confirming wheel diameter, width, and the exact replacement size helps preserve the S5’s appearance while avoiding preventable clearance or setup issues.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Audi S5?
Yes. A 2011 Audi S5 may still use a 255/35R19 tire after modification, but aftermarket wheels, different offsets, suspension changes, or altered ride height can all change how that size sits in the wheel opening. The tire code alone does not guarantee the same result on every setup.
Checking wheel width, wheel offset, and clearance at full steering lock becomes especially important when the car has been lowered or fitted with non-original wheels. Even small changes can affect inner clearance, fender room, and sidewall position, so the complete wheel-and-tire package deserves inspection before replacement.
What should I inspect before driving a 2011 Audi S5 on new tires?
Before driving a 2011 Audi S5 on new tires, inspect the wheels for bends, cracks, and bead-seat damage, then confirm inflation pressure, lug torque, and overall tire condition after installation. It is also wise to look at alignment-related wear patterns on the old tires so any underlying chassis issue is addressed early.
A performance coupe or cabriolet can expose suspension and steering problems quickly, so the first road test should be attentive and gradual. Uneven tracking, rubbing, vibration, or rapid pressure loss should be corrected before longer use, especially on a low-profile 255/35R19 setup that leaves less room for wheel or suspension issues.
How often should tires on a 2011 Audi S5 be inspected?
Tires on a 2011 Audi S5 should be inspected regularly, not just when tread appears low. A visual check for cuts, bulges, cracking, punctures, and uneven wear is worthwhile throughout the driving season, and pressure should be monitored consistently because low-profile performance tires can be sensitive to underinflation.
Cars that are driven less often still need attention, since age, storage conditions, and long periods of sitting can affect tire condition even when mileage stays low. Looking over the 255/35R19 tires before spirited driving or a longer trip helps catch developing issues before they become a ride, handling, or safety problem.
