The 2010 Audi A4 sits in the B8 generation, a point where Audi’s compact luxury sedan blended sharper styling, confident road manners, and everyday refinement in a distinctly modern package. Buyers looking at this exact car are usually balancing clean original fitment with the realities of current wheel and tire setups. Tire selection on the 2010 Audi A4 centers on four radial sizes: 225/50R17, 245/45R17, 245/40R18, and 255/35R19, with fitment changing by sub-model and sport package. That opens up meaningful choice in wheel diameter, tire series, and sidewall presentation, including blackwall, redline, and raised white letter options in some sizes. The right pick starts with the exact trim and wheel size already on the car.
Which Tire Size Is Right for The 2010 Audi A4
The 2010 Audi A4 uses four different tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Two sizes use 17-inch rims, one uses an 18-inch rim, and the sport-package fitment can also extend to a 19-inch setup. Before choosing a tire, confirm the trim level and measure the wheels currently on the car, especially if it has been modified or upgraded from its original configuration.
A 225/50R17 tire is a metric radial size with a 225-millimeter nominal section width, a 50-series aspect ratio, and fitment on a 17-inch rim. On the 2010 Audi A4, this size serves a straightforward modern radial fitment and suits buyers keeping a more standard 17-inch wheel setup. Available choices in this size center on blackwall tires from BFGoodrich and Nitto, with series including g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. It is the size to evaluate when the car is equipped with the narrower 17-inch wheel package and the goal is staying with that factory-style diameter.
A 245/45R17 tire uses a 245-millimeter nominal section width, a 45-series profile, and a 17-inch rim, making it wider and lower in profile than 225/50R17 while staying on the same wheel diameter. For the 2010 Audi A4, this is still a primary radial fitment, but it belongs to a different sub-model setup and should not be chosen by wheel diameter alone. Product selection is broader here, with BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac offerings in blackwall, redline, and raised white letter styles. This size is worth careful consideration when appearance and brand variety matter as much as staying with a 17-inch wheel.
A 245/40R18 tire keeps the 245-millimeter nominal width of the 17-inch alternative but uses a lower 40-series profile to fit an 18-inch rim. On the 2010 Audi A4, this radial size appears on upper trims and also overlaps with the sport-package setup, so it is important to match it to the actual wheels on the car. Choices include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and raised white letter options available depending on the series. It is the right size to review when the car already carries an 18-inch package and the buyer wants both fitment accuracy and style choice.
A 255/35R19 tire is a metric radial with a 255-millimeter nominal width, a short 35-series sidewall, and fitment on a 19-inch rim. For the 2010 Audi A4, this size is tied to the sport-package fitment and represents the largest wheel diameter used among the covered configurations. Available options focus on blackwall tires from BFGoodrich across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size deserves close attention when the car wears 19-inch wheels, since wheel width, suspension condition, and clearance become especially important with a lower-profile setup.
Tire fitment on the 2010 Audi A4 changes by trim, so the sub-model matters before any tire decision is made. Some versions stay on 17-inch wheels, while others move to 18-inch or 19-inch setups that call for a different tire size and profile.

2010 Audi A4 2.0T Premium
The 2010 Audi A4 2.0T Premium uses a single 17-inch radial tire fitment built around the 225/50R17 size. That keeps selection focused on choosing among available blackwall performance-oriented options rather than sorting through multiple primary sizes.
The 2010 Audi A4 2.0T Premium Plus uses a 17-inch radial setup with the wider 245/45R17 size. Tire choice here is more about comparing available brands, tire series, and sidewall treatments while confirming that the car still carries the correct 17-inch wheels.
The 2010 Audi A4 2.0T Prestige uses a single 18-inch radial fitment in 245/40R18. That points the buyer toward matching the existing wheel diameter first, then choosing among blackwall, redline, or raised white letter options within the correct size.
The 2010 Audi A4 2.0T w/Sport Pkg. can use either an 18-inch or 19-inch radial tire setup, making wheel confirmation the first step. Tire selection depends on whether the car is currently equipped with the 245/40R18 or 255/35R19 package rather than the sport package name alone.
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.

Owners of a 2010 Audi A4 usually need to sort out trim-specific tire size, wheel diameter, and the product differences within each fitment. These FAQs focus on exact sizing, radial fitment, appearance choices, and the checks worth making before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2010 Audi A4?
The 2010 Audi A4 uses four different tire sizes: 225/50R17, 245/45R17, 245/40R18, and 255/35R19. Fitment depends on the exact sub-model, with the 2.0T Premium using 225/50R17, the 2.0T Premium Plus using 245/45R17, the 2.0T Prestige using 245/40R18, and the 2.0T w/Sport Pkg. using either 245/40R18 or 255/35R19.
That means the first step is identifying the trim level and then confirming the wheels actually on the car. A4s are often updated with different factory-style wheels or aftermarket sets, so the correct tire size should match the wheel diameter and overall setup currently installed rather than the model name alone.
What size rim does a 2010 Audi A4 use?
A 2010 Audi A4 can use 17-inch, 18-inch, or 19-inch rims depending on sub-model and package. The 225/50R17 and 245/45R17 sizes fit 17-inch rims, 245/40R18 fits an 18-inch rim, and 255/35R19 fits a 19-inch rim.
Rim diameter is the fastest way to narrow down the right tire size, but it is not the only thing to verify. Width still matters, and a car that has changed wheels over time may not match the trim’s original setup, so checking the wheel markings before selecting tires helps avoid a mismatch.
Why does the 2010 Audi A4 have more than one tire size?
The 2010 Audi A4 has more than one tire size because different trims and package levels used different wheel diameters and tire profiles. Some versions stay on 17-inch wheels, while others move to 18-inch or 19-inch setups that change both width and sidewall height.
That variation is normal for a modern sport sedan, but it means tire selection should start with the exact configuration on the car. Looking only at the year and model can lead to the wrong choice, especially on a sport-package A4 that may share one size with another trim yet also offer a larger wheel package.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Audi A4?
Start with the correct size for the exact sub-model and wheel diameter, then compare the construction and character of the available radial tires in that fitment. On a 2010 Audi A4, the choice may involve 17-, 18-, or 19-inch sizing, along with differences in series such as g-Force, NT555 G2, Street Pro III, Drag Radial, or Phenom T/A.
After size is confirmed, focus on how the car will be used and how you want it to look. Some sizes offer only blackwall tires, while others add redline or raised white letter options, so the final decision often comes down to balancing appearance, wheel compatibility, and the specific product characteristics available in that size.
What sidewall styles are available for 2010 Audi A4 tires?
Sidewall style depends on tire size. Blackwall choices are available across all four primary 2010 Audi A4 sizes, while 245/45R17 and 245/40R18 also offer redline and raised white letter options through Pro-Trac Street Pro III.
That gives some A4 owners more visual flexibility than others, especially on the 17-inch and 18-inch wider fitments. A sidewall treatment does not change the basic size requirement, so the better approach is to confirm the proper fitment first and then decide whether the car looks best with a clean blackwall or a more distinctive period-inspired accent.
What brands offer tires for the 2010 Audi A4?
Tires for the 2010 Audi A4 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, depending on size. BFGoodrich appears across all four primary sizes, while Nitto is offered in 225/50R17, 245/45R17, and 245/40R18, and M&H Racemaster and Pro-Trac appear in selected 17-inch and 18-inch fitments.
Brand choice should come after the correct size is locked in, since not every brand appears in every fitment. Once the size is confirmed, compare the available series, sidewall style, and wheel-width suitability within that group rather than assuming the same brand lineup carries over from one A4 trim or wheel package to another.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Audi A4?
A period-style 2010 Audi A4 usually starts with keeping the correct trim-specific size and wheel diameter in place, then choosing a tire whose sidewall presentation suits the car’s look. Blackwall is the common visual direction across all sizes, while 245/45R17 and 245/40R18 also open the door to redline or raised white letter treatments.
Most buyers aiming for a clean original-era appearance will want the tire to match the wheel package the car actually wears. Since appearance preferences on a 2010 model can vary between understated luxury and sport-oriented styling, using original sales literature, enthusiast references, or marque-specific guidance can help settle the final look.
How does tire construction affect the appearance of a restored 2010 Audi A4?
On the 2010 Audi A4, construction is less about bias-ply versus radial and more about the visual details within a modern radial tire. All primary fitments are radial, so appearance differences come from sidewall style, profile, and how the tire fills the wheel opening on the correct 17-, 18-, or 19-inch setup.
That makes size accuracy especially important to the finished look of the car. A lower-profile 19-inch setup presents the A4 differently than a 17-inch fitment, even before sidewall treatment is considered, so a restoration-minded buyer should choose the tire size that matches the intended trim and wheel presentation first.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Audi A4?
Yes, modifications can affect tire fitment on a 2010 Audi A4, especially because this model already spans 17-, 18-, and 19-inch wheel diameters across its original configurations. Aftermarket wheels, altered offsets, suspension changes, or a lowered ride height can change how a 225/50R17, 245/45R17, 245/40R18, or 255/35R19 tire sits in the wheel opening.
A modified A4 should be checked at the wheel rather than matched only by trim name. Confirm the actual diameter and width of the wheels, then look at steering travel and fender clearance before choosing a tire, since even a correct nominal size can create problems if the car no longer matches its original setup.
What should I inspect before driving a 2010 Audi A4 on new tires?
Before driving a 2010 Audi A4 on new tires, inspect the wheels for correct diameter and condition, make sure the tires match the intended size, and verify proper inflation. It is also smart to check for obvious suspension or alignment issues that could affect how the new tires wear and how the car tracks on the road.
A short road test should be approached as a final fitment check, not just a routine drive. Listen for rubbing, pay attention to steering response, and recheck air pressure after the first miles, especially if the car has sat for long periods or recently received different wheels, springs, or other chassis-related changes.
How often should tires on a 2010 Audi A4 be inspected?
Tires on a 2010 Audi A4 should be inspected regularly, with a close look before longer drives and periodic checks even when the car is used lightly. Watch for uneven wear, sidewall cuts, bulges, visible cracking, and gradual air loss, since all of those can affect a modern radial tire long before the tread looks completely worn.
Inspection matters even more on a collector-kept or weekend-driven A4 because low mileage does not prevent age-related deterioration. A routine walkaround, pressure check, and occasional look at tread wear across the full contact patch will help catch wheel, alignment, or storage-related problems before they become a road-use issue.
