The 2011 Audi A4 sits in the B8 generation, a compact luxury sport sedan known for balanced road manners, crisp styling, and a chassis that rewards careful setup. Buyers looking at this exact model often find that tire selection depends less on guesswork and more on matching the car’s trim and wheel package. This Audi A4 uses radial tire fitments in four sizes: 225/50R17, 245/45R17, 245/40R18, and 255/35R19. Available choices range from blackwall performance-oriented tires to select RWL and redline options in certain sizes. The right decision starts with confirming the exact sub-model and wheel diameter, then choosing the tire style and series that suits the car’s intended look and road use.
Which Tire Size Is Right for The 2011 Audi A4
The 2011 Audi A4 uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Two sizes fit 17-inch wheels, while the sport-package fitments move to 18-inch or 19-inch rims. Before choosing a tire, identify whether the car is a Premium, Premium Plus, or w/Sport Pkg. model and confirm the wheel diameter actually on the vehicle.
225/50R17 is a metric radial size in which 225 is the section width in millimeters, 50 is the aspect ratio, R designates radial construction, and 17 is the rim diameter in inches. On the 2011 Audi A4, this size is tied to a 17-inch wheel setup and keeps the selection focused on modern radial construction. Available choices include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. This size is the one to evaluate when the car has the Premium trim and a standard-height sidewall profile on a 17-inch rim.
245/45R17 uses the same metric radial sizing system, with a 245-millimeter nominal width, a 45-series profile, radial construction, and a 17-inch rim. For the 2011 Audi A4, this fitment stays on a 17-inch wheel but adds width compared with 225/50R17, making exact sub-model confirmation important. Product selection is broader here, with blackwall options from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III versions in RWL and redline. This size deserves close attention on Premium Plus cars or any A4 wearing 17-inch wheels that may have been changed over time.
245/40R18 is a metric radial size that combines a 245-millimeter width with a lower 40-series profile on an 18-inch wheel. On the 2011 Audi A4, it belongs to the w/Sport Pkg. fitment range, so it should not be assumed for other trims without checking the car’s actual wheel setup. Available tires include blackwall designs from BFGoodrich, Nitto, and M&H Racemaster, along with Pro-Trac Street Pro III offerings in redline and RWL. This size is worth choosing when the car has the sport-package 18-inch wheel arrangement and the goal is to stay aligned with that lower-profile presentation.
255/35R19 is a metric radial size with a 255-millimeter section width, a 35-series profile, and a 19-inch rim diameter. For the 2011 Audi A4, this is the largest primary fitment in the group and is associated with the w/Sport Pkg. configuration using 19-inch wheels. Available options center on blackwall tires from BFGoodrich in g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size should be considered only after confirming that the car is equipped with the 19-inch sport-package wheel setup and has the clearance to match that configuration.
Tire fitment on the 2011 Audi A4 varies by sub-model, so trim identification matters before comparing products. Premium, Premium Plus, and w/Sport Pkg. cars do not all use the same tire size, and the sport-package cars also introduce larger wheel diameters.

2011 Audi A4 Premium
The 2011 Audi A4 Premium uses a single radial tire fitment based around a 17-inch wheel. Tire selection here is mainly about choosing among the available blackwall performance-oriented options while confirming that the car still has its correct wheel diameter.
The 2011 Audi A4 Premium Plus uses a different 17-inch radial size than the Premium model, so the two trims should not be treated as interchangeable. Once the wheel setup is confirmed, the main decision becomes sidewall treatment, brand, and tire series within that correct size.
The 2011 Audi A4 w/Sport Pkg. uses either an 18-inch or 19-inch radial fitment, making wheel diameter the first thing to verify on the car. After that, the choice shifts to whether the owner wants a blackwall presentation or, in the 18-inch size, a more distinctive RWL or redline look.
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 A4?
The 2011 Audi A4 uses four primary radial tire sizes: 225/50R17, 245/45R17, 245/40R18, and 255/35R19. The correct size depends on the exact sub-model and wheel package. Premium models use 225/50R17, Premium Plus models use 245/45R17, and w/Sport Pkg. cars use either 245/40R18 or 255/35R19.
That means the first step is identifying the trim and confirming the wheel diameter actually installed on the car. A4s may have changed wheels over time, so the tire placard, current rim size, and overall setup should all agree before a replacement tire is chosen.
What size rim does a 2011 Audi A4 use?
A 2011 Audi A4 can use 17-inch, 18-inch, or 19-inch rims depending on the sub-model and wheel package. The 225/50R17 and 245/45R17 fitments both use 17-inch rims, while 245/40R18 uses an 18-inch rim and 255/35R19 uses a 19-inch rim.
Rim diameter is the non-negotiable starting point because a tire must match the wheel’s diameter exactly. Once that is confirmed, the next checks are wheel width, the correct size for the trim, and whether any aftermarket wheel change has altered the tire dimensions the car should be using.
Why does the 2011 Audi A4 have more than one tire size?
The 2011 Audi A4 has more than one tire size because fitment changes with trim and sport-package wheel configuration. Premium and Premium Plus models use different 17-inch sizes, while the w/Sport Pkg. configuration moves to lower-profile 18-inch or 19-inch tires matched to larger wheels.
That variation means tire selection is tied to the actual configuration of the car, not just the year and model name. A careful buyer should verify the sub-model, inspect the wheels on the vehicle, and avoid assuming that any Audi A4 tire size from 2011 will suit every version.
Choosing the Right Tire
What should I consider when choosing a 2011 Audi A4 tire?
Start with the correct tire size for the exact 2011 Audi A4 trim and wheel diameter, since Premium, Premium Plus, and w/Sport Pkg. cars do not all use the same fitment. After size is settled, compare construction, sidewall style, tire series, and any meaningful rim-width or load figures tied to the products in that size.
A buyer choosing between available tires should think about how the car is driven and how it should look. Some sizes stay strictly blackwall, while others add RWL or redline choices, so the decision can involve both appearance and the character of the tire lineup.
What sidewall styles are available for 2011 Audi A4 tires?
Sidewall style depends on the tire size selected for the 2011 Audi A4. Blackwall tires are available across all four primary sizes, while RWL and redline options appear in the 245/45R17 and 245/40R18 fitments through Pro-Trac Street Pro III tires.
That means appearance choice is broader on certain 17-inch and 18-inch setups than it is on the 225/50R17 or 255/35R19 sizes. Buyers who want a more traditional blackwall or a more distinctive raised white letter or redline presentation should begin by confirming which size their A4 actually uses.
What brands offer tires for the 2011 Audi A4?
Tires for the 2011 Audi A4 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on the size. BFGoodrich appears across all four fitments, Nitto is offered in several 17-inch and 18-inch sizes, and M&H Racemaster and Pro-Trac appear in selected 245-width applications.
Brand comparison matters most after the correct size is confirmed, because not every line is available in every fitment. Once the size is settled, the useful differences are usually tire series, sidewall style, rim-width specification, and whether the buyer wants a more standard street presentation or something more specialized.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Audi A4?
A period-style 2011 Audi A4 tire choice starts with using the correct original-size format for the car’s trim and wheel package, since all of its primary fitments are modern metric radials. From there, blackwall tires will usually preserve the most familiar late-model luxury sport sedan appearance, especially on sizes where only blackwall options are offered.
Appearance choice becomes more individualized on 245/45R17 and 245/40R18, where RWL and redline versions are also available. Buyers aiming for a showroom-era look should compare the current wheel setup, trim level, and visual goals carefully rather than assuming that every available sidewall treatment reflects how the car originally left the factory.
How does tire construction affect the appearance of a restored 2011 Audi A4?
Tire construction is straightforward on a restored 2011 Audi A4 because the primary fitments are all radial. That keeps the visual decision centered less on bias-ply versus radial shape and more on the actual tire size, profile, and sidewall treatment chosen for the wheel package on the car.
A 17-inch Premium or Premium Plus setup can present differently from an 18-inch or 19-inch sport-package car even before brand is considered. Matching the wheel diameter and profile to the intended trim appearance usually matters more here than chasing unusual styling details that may not suit the A4’s original character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Audi A4?
Yes, modifications can affect tire fitment on a 2011 Audi A4, especially because this model already spans 17-inch, 18-inch, and 19-inch wheel diameters. Aftermarket wheels, altered offsets, suspension changes, or lowering can change the clearance relationship around the fenders, steering components, and inner wheelhouse.
A4s that no longer wear their original wheel package should be checked carefully before replacement tires are chosen. Verifying actual wheel diameter and width, then checking for rubbing at full steering lock and normal suspension travel, is much more reliable than assuming the current tire setup still reflects the car’s original trim-based fitment.
What should I inspect before driving a 2011 Audi A4 on new tires?
Before driving a 2011 Audi A4 on new tires, inspect the wheels for damage, confirm that the tire size matches the car’s trim and rim diameter, and make sure all four tires are seated and inflated correctly. It also helps to look over the suspension and steering for worn parts that could affect wear or tracking.
A short first drive should include listening for rubbing, checking straight-line behavior, and rechecking pressure after the tires have settled in. On a car with 18-inch or 19-inch fitments, clearance verification is especially worthwhile if the wheels, ride height, or alignment have been changed from stock.
What should I check before a longer drive in a 2011 Audi A4?
Before a longer drive in a 2011 Audi A4, confirm that the tires are the correct size for the car, inspect tread and sidewalls for cuts or bulges, and make sure inflation pressure is even and stable. It is also smart to check for uneven wear that could point to alignment or suspension issues.
Longer trips place more importance on consistency across the full set, especially on a car that uses lower-profile sport-package tires. A final walkaround should include looking for air loss, wheel damage, and any sign of contact inside the wheel openings so minor issues do not become road-trip problems.
