The 2010 Audi A5 Quattro sits in the modern grand-touring side of Audi’s lineup, blending coupe and Cabriolet style with all-wheel-drive confidence and a chassis that responds noticeably to tire choice. On this exact model, tire selection starts with two radial fitments, 245/40R18 and 255/35R19, so the first step is confirming which wheel package is on the car. From there, the choice shifts toward tire character, with blackwall performance radials available in both sizes and added redline or raised white letter styling in 245/40R18. For a stock-height street car, appearance, wheel diameter, and the intended balance of modern handling feel and visual personality should guide the decision.
Which Tire Size Is Right for The 2010 Audi A5 Quattro
The 2010 Audi A5 Quattro uses two primary tire sizes, and both are radial fitments tied to different wheel diameters: 18-inch and 19-inch. All covered sub-models can use either size, so the key step is confirming which wheels are actually on the car before choosing a tire. Once wheel diameter is verified, the real decision becomes tread and series selection, sidewall style where available, and the overall look and driving character you want from the car.
245/40R18 is a modern metric radial size in which 245 indicates section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2010 Audi A5 Quattro, this size suits the 18-inch wheel package and keeps the tire choice firmly in contemporary radial territory. Available options include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and raised white letter sidewall treatments across several series. This size is the one to evaluate when the car is running 18-inch wheels and you want the broadest mix of performance-oriented and appearance-driven choices.
255/35R19 is also a modern metric radial size, with 255 marking section width in millimeters, 35 indicating a lower-profile sidewall, R for radial construction, and 19 for the required rim diameter. For the 2010 Audi A5 Quattro, this size belongs with the 19-inch wheel setup and points toward a more visibly low-profile presentation. BFGoodrich offers this fitment across multiple g-Force series, all in blackwall form, giving the buyer several ways to stay within the correct size while comparing product character. This is the right size to consider after confirming a 19-inch wheel, especially if maintaining the larger-wheel look matters.
Fitment is straightforward across the covered 2010 Audi A5 Quattro sub-models because each one uses the same two radial tire sizes. The important check is not trim level but the actual wheel diameter on the car, since 18-inch and 19-inch wheels require different tires.

2010 Audi A5 Quattro 2.0
The 2010 Audi A5 Quattro 2.0 uses the same two radial size options found across the rest of the covered lineup. Tire selection comes down to confirming whether the car wears 18-inch or 19-inch wheels, then choosing the right product style and series within that fitment.
The 2010 Audi A5 Quattro 3.2 follows the same tire-size pattern, with both primary radial fitments applying to this sub-model. That keeps the decision focused on wheel diameter first, then on whether a blackwall performance tire or another available sidewall treatment better suits the car.
The 2010 Audi A5 Quattro Cabriolet shares the same two radial tire sizes as the coupe sub-models covered here. For selection purposes, the crucial step is matching the tire to the car’s current 18-inch or 19-inch wheel package before comparing available brands, series, and sidewall presentation.
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 2010 Audi A5 Quattro?
The 2010 Audi A5 Quattro uses two primary tire sizes: 245/40R18 and 255/35R19. Both are radial fitments, and both appear across the covered 2.0, 3.2, and Cabriolet sub-models, so the car does not depend on a unique sub-model-only size within this group.
The real fitment decision is confirming which wheel diameter is on the car now. An A5 Quattro with 18-inch wheels needs 245/40R18, while a car with 19-inch wheels needs 255/35R19. If the wheels have ever been changed, verify the actual wheel size on the vehicle before choosing a tire.
What size rim does a 2010 Audi A5 Quattro use?
A 2010 Audi A5 Quattro uses either an 18-inch or 19-inch rim, depending on which tire size is on the car. The 245/40R18 fitment pairs with an 18-inch rim, and the 255/35R19 fitment pairs with a 19-inch rim.
Because this model uses two wheel diameters, rim size should be checked before anything else. Looking only at the model year and sub-model is not enough if the car has had wheel changes over time. Confirm the wheel diameter stamped on the wheel or match it to the current tire size before comparing products.
Do all 2010 Audi A5 Quattro sub-models use the same tire size?
The covered 2010 Audi A5 Quattro sub-models share the same two tire sizes rather than using separate trim-specific fitments. The 2.0, 3.2, and Cabriolet all use 245/40R18 and 255/35R19 as their primary radial size options.
That makes the selection process simpler, but it does not eliminate the need to confirm the wheel package on the individual car. A Cabriolet or coupe may be wearing either size, and an owner should match the replacement tire to the actual wheel diameter in use rather than assuming one size applies automatically.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 or 255/35R19 tire for a 2010 Audi A5 Quattro?
Start with the correct size for the wheel diameter on the car, since 245/40R18 and 255/35R19 are not interchangeable across 18-inch and 19-inch rims. Both fitments are radial, so the next comparison points are tire series, sidewall style, and product specifications such as rim-width compatibility and load figures where those are stated.
A buyer should also think about how the car is used and how it should look. The 18-inch size offers the widest variety, including blackwall, redline, and raised white letter options, while the 19-inch size stays focused on blackwall performance-style choices. Matching the tire to the wheel, intended use, and visual goal usually narrows the field quickly.
What sidewall styles are available for 2010 Audi A5 Quattro tires?
Sidewall style depends on size. In 245/40R18, available sidewall treatments include blackwall, redline, and RWL, which can be described as raised white letter. In 255/35R19, the available products are blackwall only, so that size keeps a more understated modern appearance.
The practical effect is that wheel diameter influences styling choice as much as fitment. Anyone wanting a stronger visual statement has more flexibility in 245/40R18, while 255/35R19 stays closer to a contemporary performance look. Appearance matters, but the sidewall style still needs to be chosen within the correct tire size for the wheel.
What brands offer tires for the 2010 Audi A5 Quattro?
Available brands for the 2010 Audi A5 Quattro include BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand coverage varies by size, with 245/40R18 offering the broadest mix and 255/35R19 centered on BFGoodrich options across several g-Force series.
Brand choice should be compared alongside size, series, and sidewall treatment rather than treated as a stand-alone decision. A buyer looking at 18-inch fitment can weigh several presentation and usage styles, while the 19-inch fitment is more narrowly performance-oriented in appearance. The right comparison is the complete tire specification for the exact wheel package on the car.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Audi A5 Quattro?
A period-style choice for a 2010 Audi A5 Quattro starts with keeping the correct wheel diameter and matching the tire to the car’s original-looking overall presentation. That usually means selecting either 245/40R18 or 255/35R19 according to the wheel package, then narrowing the choice by sidewall treatment and tire series.
The 245/40R18 size offers the most visual variety, including blackwall, redline, and raised white letter options, while 255/35R19 remains blackwall only. Anyone seeking exact historical authenticity for a specific car should compare the finished look against original window-sticker, dealer, or marque-reference material before making an appearance-driven choice.
How does tire construction affect the appearance of a restored 2010 Audi A5 Quattro?
On the 2010 Audi A5 Quattro, appearance differences come less from construction changes and more from size, profile, and sidewall treatment, because the primary fitments are radial. A 245/40R18 or 255/35R19 tire keeps the car in a modern low-profile radial look rather than a vintage tall-sidewall presentation.
Visual character still changes noticeably within that radial format. Blackwall keeps the cleanest contemporary look, while redline or raised white letter options in 245/40R18 add more personality. For a restoration-minded car, preserving the proper wheel diameter and tire profile matters at least as much as the brand name on the sidewall.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Audi A5 Quattro?
Yes. A 2010 Audi A5 Quattro may share the same primary sizes across its covered sub-models, but wheel changes, altered offset, suspension lowering, or body modifications can all affect whether the intended tire still clears properly. That matters with both 245/40R18 and 255/35R19 fitments.
Anyone replacing tires on a modified car should verify wheel diameter, wheel width, and clearance at the fender, suspension, and steering range before choosing a new set. Even when the size is correct on paper, aftermarket setup changes can alter the space available and should be checked before road use.
What should I inspect before driving a 2010 Audi A5 Quattro on new tires?
Before driving, inspect inflation pressure, bead seating, lug torque, and basic clearance around the wheel wells and suspension. A 2010 Audi A5 Quattro should also be checked for any rubbing at full steering lock if the car has non-stock wheels or a lowered stance.
A short initial drive should be followed by another inspection for air loss, contact marks, or uneven settling. It also helps to look over the rest of the chassis, including alignment condition and worn suspension parts, because fresh tires can reveal issues that older, worn tires may have been masking.
How often should tires on a 2010 Audi A5 Quattro be inspected?
Tires on a 2010 Audi A5 Quattro should be inspected regularly, not just when tread looks low. Check them for uneven wear, cuts, bulges, cracking, and pressure loss, and give them extra attention before longer drives or after the car has been parked for an extended period.
Routine inspection is especially important on a performance-oriented coupe or Cabriolet where low-profile tires can be more sensitive to road hazards and alignment changes. Looking at the tires and wheels together helps catch problems early, including bent rims, abnormal shoulder wear, or signs that the current setup no longer matches the car’s condition.
