The 2007 Audi A4 sits in the B7 generation, a period when Audi blended compact luxury, confident road manners, and crisp European styling into a platform that still attracts daily drivers and enthusiast owners. Tire fitment on this A4 stays firmly in modern radial territory, but the exact size depends on the sub-model and wheel package, with 215/55R16, 235/45R17, and 235/40R18 all in use. That gives owners a real choice between comfort-oriented sizing, larger wheel fitments, and product differences across brands and tire series. Getting the right tire starts with confirming the exact sub-model and wheel diameter already on the car.
Which Tire Size Is Right for The 2007 Audi A4
The 2007 Audi A4 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three fitments are radial, but they are matched to 16-inch, 17-inch, or 18-inch rims, so confirming the wheel size on the car is the first step before comparing tire series, brand choices, or sidewall appearance.
235/45R17 is a metric radial size with a 235-millimeter nominal section width, a 45-series profile, and a 17-inch rim requirement. For the 2007 Audi A4, it is used on specific sub-model and wheel combinations, making it important to verify the actual 17-inch wheel setup before selecting a tire. Product choices in this size center on Blackwall radials from BFGoodrich and Nitto, with series including g-Force Sport Comp 2, g-Force Comp 2 AS, and NT555 G2. It is the right direction when the car is already configured around the 17-inch fitment and that wheel diameter is staying in place.
235/40R18 is a metric radial size that keeps the same nominal 235-millimeter width as the 17-inch fitment, but uses a shorter 40-series profile on an 18-inch rim. On the 2007 Audi A4, this size is tied to the larger-wheel configurations used by S Line and certain 3.2 models, so it should be selected only after confirming the car’s actual wheel diameter. Available products are Blackwall radials from BFGoodrich and Nitto, with tire series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size makes sense when maintaining the 18-inch setup already on the vehicle.
Tire fitment on the 2007 Audi A4 varies by sub-model, and some versions use more than one wheel-and-tire combination. Confirming the exact trim and the wheel diameter already on the car matters before choosing a replacement tire, especially where 16-inch, 17-inch, and 18-inch setups overlap within the same model line.

2007 Audi A4 2.0T
The 2007 Audi A4 2.0T uses either a 215/55R16 radial or a 235/45R17 radial, depending on the wheel package on the car. Tire selection starts with confirming whether the car has 16-inch or 17-inch wheels, then comparing the available product choices within that exact size.
The 2007 Audi A4 2.0T S Line uses the 235/40R18 radial fitment. That keeps the decision focused on selecting among the available 18-inch tire series and confirming that the car still retains its proper 18-inch wheel setup.
The 2007 Audi A4 3.2 can use either 235/45R17 or 235/40R18 radial tires. Choosing correctly means checking whether the car currently carries 17-inch or 18-inch wheels, then matching the tire to that wheel diameter before comparing product differences.
The 2007 Audi A4 3.2 S Line uses the 235/40R18 radial size. That makes the main selection question less about size and more about choosing the right 18-inch tire series for the car’s intended road use and overall presentation.
The 2007 Audi A4 Cabriolet uses either 215/55R16 or 235/45R17 radial tires, depending on its wheel configuration. Checking the actual rim diameter on the car is the key first step, after which the choice becomes one of tire style, brand, and driving character within the correct size.
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 questions for the 2007 Audi A4 usually come down to correct size by sub-model, wheel diameter, radial tire selection, and the difference between appearance-focused and performance-oriented options. The answers below focus on practical fitment, product choice, and road-use checks.
Tire Size & Fitment
What tire size fits a 2007 Audi A4?
The 2007 Audi A4 uses three primary tire sizes: 215/55R16, 235/45R17, and 235/40R18. The correct size depends on the exact sub-model and the wheel package on the car, with some trims using more than one fitment depending on whether they carry 16-inch, 17-inch, or 18-inch rims.
The practical first step is to confirm the wheel diameter already installed rather than choosing by model name alone. A 2.0T, 3.2, or Cabriolet may share the same model designation while using different wheel sizes, so checking the existing tire sidewall and wheel setup helps prevent ordering a tire for the wrong rim.
What size rim does a 2007 Audi A4 use?
A 2007 Audi A4 can use 16-inch, 17-inch, or 18-inch rims, depending on the sub-model and wheel configuration. Those rim diameters correspond to the three primary tire sizes used on this model line: 215/55R16, 235/45R17, and 235/40R18.
Rim diameter is the most important fitment check because each tire size is built for a specific wheel diameter and cannot be mixed across 16-, 17-, and 18-inch wheels. Looking at the marking on the current tire or wheel is the simplest way to verify what the car actually needs before comparing brands or tread styles.
Do all 2007 Audi A4 sub-models use the same tire size?
No. The 2007 Audi A4 uses different tire sizes across its sub-models, and some trims have more than one acceptable size depending on the wheel package. The 2.0T and Cabriolet use 215/55R16 or 235/45R17, the 3.2 uses 235/45R17 or 235/40R18, and the S Line versions use 235/40R18.
That variation means sub-model identification alone is helpful but not always enough. The safest approach is to confirm both the trim and the actual wheel diameter on the car, especially if wheels may have been changed over time. Once that is settled, selecting the correct tire becomes much more straightforward.
Choosing the Right Tire
What should I consider when choosing a 2007 Audi A4 tire?
Start with the correct tire size for the car’s exact wheel diameter and sub-model, then compare the available radial options within that size. For the 2007 Audi A4, the decision may involve 215/55R16, 235/45R17, or 235/40R18, and each size has its own product mix, rim-width specifications, and intended character.
After size is confirmed, look at how the tire will be used and how you want the car to present. Some options lean toward a sport-oriented modern look, while 215/55R16 also includes Redline and Wide Whitewall choices that create a more distinctive appearance. Wheel compatibility and the vehicle’s current setup should guide the final decision.
What sidewall styles are available for 2007 Audi A4 tires?
Sidewall style depends on the tire size. In 215/55R16, available choices include Blackwall, Redline, and Wide Whitewall, while the 235/45R17 and 235/40R18 fitments center on Blackwall radials. That makes the 16-inch size the most appearance-sensitive option among the three primary A4 fitments.
Sidewall choice changes the visual character of the car more than the fitment itself, so it should be selected after the correct size is confirmed. A Blackwall keeps the presentation contemporary and understated, while Redline or Wide Whitewall creates a much more deliberate styling statement on an A4 already equipped with the 16-inch setup.
What brands offer tires for the 2007 Audi A4?
Tires for the 2007 Audi A4 are available from BFGoodrich, American Classic, and Nitto, depending on size. BFGoodrich appears across all three primary fitments, American Classic is offered in 215/55R16, and Nitto is available in the 235/45R17 and 235/40R18 sizes.
Brand choice should come after the right size and wheel diameter are verified. Once that is settled, it makes sense to compare tire series, sidewall style, and rim-width compatibility within the correct fitment. That approach keeps the selection grounded in proper fitment instead of choosing a brand first and forcing the tire decision around it.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Audi A4?
A period-style approach for a 2007 Audi A4 starts with preserving the correct tire size for the car’s actual wheel setup, then choosing a tire that matches the look you want. In 215/55R16, the available choices include Blackwall, Redline, and Wide Whitewall radials, while the larger 17-inch and 18-inch fitments remain Blackwall-focused.
That means the visual direction changes with the wheel package already on the car. Owners aiming for a clean early-2000s sport-sedan look may stay with Blackwall tires, while a more personalized presentation can come from the 16-inch Redline or Wide Whitewall options. Appearance should always be balanced against proper size, wheel fit, and intended use.
Does correct tire fitment matter for a 2007 Audi A4 restoration?
Yes, correct tire fitment matters because the 2007 Audi A4 used more than one wheel-and-tire combination across its sub-models. Choosing the right 16-inch, 17-inch, or 18-inch fitment helps preserve the car’s proportions and avoids the mismatched look that comes from mounting a tire meant for a different wheel diameter.
Appearance and stance are only part of the equation. Proper fitment also affects how naturally the tire sits in the wheel opening and whether the setup remains compatible with the car’s current wheels. For owners who care deeply about historical accuracy, vehicle-specific documentation and marque expertise are still worth consulting before making a final appearance choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Audi A4?
Yes. A 2007 Audi A4 may have had aftermarket wheels, suspension changes, or alignment-related modifications over time, and any of those can affect tire fitment. Even when the car originally used 215/55R16, 235/45R17, or 235/40R18, changes to wheel diameter, wheel width, or ride height can alter what safely clears the body and suspension.
That makes it important to inspect the actual setup on the car instead of assuming it still matches its original configuration. Checking wheel size, tire-to-fender clearance, and steering clearance at full lock can prevent expensive mistakes. Modified cars deserve extra attention before replacing tires with the same size printed in an old owner’s note or receipt.
What should I inspect before driving a 2007 Audi A4 on new tires?
Before driving a 2007 Audi A4 on new tires, inspect the wheel diameter, the tire size on each corner, and the general condition of the wheels themselves. It is also smart to confirm inflation pressure, look for uneven wear patterns from the previous set, and make sure there are no suspension or alignment issues that could affect the new tires immediately.
A brief clearance check is worthwhile as well, especially if the car has 17-inch or 18-inch wheels or any history of modifications. Turning the steering from lock to lock and looking for rubbing marks can reveal problems before road use. After installation, recheck pressure and monitor for vibration, pulling, or unusual contact in the first few drives.
How often should tires on a 2007 Audi A4 be inspected?
Tires on a 2007 Audi A4 should be inspected regularly rather than only when tread looks low. A routine visual check for air loss, sidewall cracking, cuts, bulges, and uneven tread wear helps catch problems early, especially on a vehicle that may alternate between daily use and longer parked periods.
Monthly pressure checks are a sensible habit, and an inspection before any longer drive adds another layer of protection. Cars fitted with lower-profile 235/45R17 or 235/40R18 tires especially benefit from watching for impact damage from potholes and rough pavement. Consistent inspection helps preserve both tire life and the way the A4 feels on the road.
