The 2004 Audi Allroad Quattro sits in the early wave of luxury wagons that blended all-weather capability with long-roof practicality and a distinctly European performance feel. It appeals to owners who want one vehicle that can still look refined, cover highway miles comfortably, and carry genuine enthusiast interest. Tire fitment centers on radial construction, with 225/55R17 as the primary size and an additional 245/45R18 fitment on certain versions. That opens up a mix of touring and performance-oriented choices, along with blackwall, redline, and wide whitewall styling in select 17-inch options. The right pick depends first on sub-model and wheel diameter, then on whether the goal is stock-style road use or a more personalized look.
Which Tire Size Is Right for The 2004 Audi Allroad Quattro
The 2004 Audi Allroad Quattro uses two primary tire sizes, and the correct choice depends on the exact sub-model and wheel diameter. Both fitments are radial, but one uses a 17-inch rim and the other uses an 18-inch rim, so confirming the wheel setup comes before comparing brands, sidewall styles, or tire series.
225/55R17 is a modern metric radial size in which 225 identifies the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter in inches. On the 2004 Audi Allroad Quattro, this size serves as a primary radial fitment and appears across both covered sub-models, making it the most broadly applicable choice on the page. Available options include BFGoodrich performance-oriented g-Force series tires as well as Silvertown Radial versions in blackwall-inspired styling, redline, and wide whitewall form. It is the size to evaluate when the Allroad is running 17-inch wheels and the goal is to balance correct fitment with either a contemporary or more custom visual presentation.
245/45R18 is also a modern metric radial size, with 245 denoting section width in millimeters, 45 indicating the aspect ratio, and 18 calling for an 18-inch wheel. On the 2004 Audi Allroad Quattro, this fitment is tied to specific 18-inch-wheel applications rather than every configuration. Product choices in this size lean toward blackwall performance radials from BFGoodrich and Nitto, including several g-Force series options and the NT555 G2. This size makes sense only after the 18-inch wheel setup has been confirmed, since rim diameter is the first requirement before comparing tread character, load figures, or rim-width compatibility.
Sub-model fitment matters on the 2004 Audi Allroad Quattro because tire size is not completely uniform across the range. The 2.7T stays with one primary size, while the 4.2 can use more than one, so confirming the exact version helps narrow the right wheel and tire combination.

2004 Audi Allroad Quattro 2.7T
The 2004 Audi Allroad Quattro 2.7T uses the 225/55R17 radial fitment. That keeps tire selection focused on choosing the right 17-inch option by series, appearance, and intended road use rather than sorting through multiple primary sizes.
The 2004 Audi Allroad Quattro 4.2 can use either 225/55R17 or 245/45R18 depending on the wheel setup. Tire selection starts with confirming whether the vehicle is on 17-inch or 18-inch rims, then comparing the available radial choices within that 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.
Best 2004 Audi Allroad Quattro Tires for Sale

These FAQs focus on the tire sizes used on the 2004 Audi Allroad Quattro, how sub-model and wheel diameter affect fitment, and what to compare when choosing among the available radial options.
Tire Size & Fitment
What tire size fits a 2004 Audi Allroad Quattro?
The 2004 Audi Allroad Quattro uses 225/55R17 and 245/45R18 radial tire sizes. The 2.7T uses 225/55R17, while the 4.2 can use 225/55R17 or 245/45R18 depending on the wheel setup fitted to the vehicle.
That means the first step is confirming the exact sub-model and the actual wheel diameter on the car. Once that is settled, the decision shifts to the type of radial tire you want, such as a blackwall performance option or, in 225/55R17, a more appearance-driven choice like redline or wide whitewall.
What size rim does a 2004 Audi Allroad Quattro use?
The 2004 Audi Allroad Quattro uses either a 17-inch or 18-inch rim, depending on the tire size. The 225/55R17 fitment uses a 17-inch wheel, and the 245/45R18 fitment uses an 18-inch wheel.
Rim diameter is the key fitment checkpoint because a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. It also helps to confirm wheel width before choosing a tire, especially on vehicles that may have had replacement wheels installed over the years.
Why does the 2004 Audi Allroad Quattro have more than one tire size?
More than one tire size appears on the 2004 Audi Allroad Quattro because fitment varies by version and wheel setup. The 2.7T stays with 225/55R17, while the 4.2 may be equipped with either 225/55R17 or 245/45R18.
That difference means tire selection is not only about the model year and nameplate. The exact sub-model and wheel diameter matter, especially on a used vehicle that may no longer be wearing its original wheels, so checking the current setup on the car is more useful than assuming one size fits every Allroad Quattro.
Choosing the Right Tire
What should I consider when choosing a 225/55R17 tire for a 2004 Audi Allroad Quattro?
A 225/55R17 tire for the 2004 Audi Allroad Quattro should first match the vehicle's 17-inch wheel setup and intended use. In this size, choices include BFGoodrich g-Force series tires for a more modern performance-oriented feel and Silvertown Radial versions that add redline or wide whitewall styling.
The practical choice comes down to how the vehicle is driven and how it should look. A blackwall performance radial suits a contemporary road-focused presentation, while redline or wide whitewall options lean more toward custom appearance, so wheel width and the vehicle's overall style direction should both be checked before deciding.
What sidewall styles are available for 2004 Audi Allroad Quattro tires?
Sidewall styling on 2004 Audi Allroad Quattro tires includes blackwall across both primary sizes, with additional redline and wide whitewall choices in 225/55R17. Those appearance options are tied to specific tire lines rather than every tire available for the vehicle.
That makes sidewall style an appearance decision after the correct size and wheel diameter have been confirmed. Buyers trying to keep the Allroad looking understated may stay with blackwall, while a more customized build can use the 17-inch redline or wide whitewall options to create a more distinctive presentation.
What brands offer tires for the 2004 Audi Allroad Quattro?
BFGoodrich and Nitto offer tires for the 2004 Audi Allroad Quattro. BFGoodrich covers both primary sizes with multiple series, while Nitto appears in the 245/45R18 fitment with the NT555 G2.
Brand comparison is most useful after the correct size has been confirmed, because the choices are not identical between the 17-inch and 18-inch fitments. It also helps to compare tire series, sidewall style, rim-width range, and load figures where shown, since those details shape which tire best matches the vehicle's setup and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Audi Allroad Quattro?
A period-style 2004 Audi Allroad Quattro tire choice starts with the correct primary size for the vehicle's wheel setup, then moves to sidewall presentation and overall character. Blackwall radials usually align most naturally with the Allroad's original-era appearance, while the 225/55R17 size also opens up more customized visual treatments.
Owners aiming for a closer early-2000s look should keep the wheel diameter and tire proportions appropriate to the vehicle before thinking about styling details. When exact originality matters, checking marque-specific references or original vehicle documentation is the best way to confirm which wheel-and-tire presentation suits the particular car.
Does correct tire fitment matter for a 2004 Audi Allroad Quattro restoration?
Correct tire fitment matters because it affects how a restored 2004 Audi Allroad Quattro sits, drives, and presents visually. Using the proper 225/55R17 or 245/45R18 size for the actual wheel setup keeps the proportions consistent with the vehicle and avoids turning the tire choice into an avoidable fitment problem.
Appearance is only part of the equation. The right rim diameter, suitable wheel width, and an appropriate sidewall style all contribute to whether the finished vehicle feels cohesive, so restoration-minded buyers should verify the wheel setup carefully before selecting a tire based mainly on brand or cosmetic treatment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Audi Allroad Quattro?
Yes, modifications can affect tire fitment on a 2004 Audi Allroad Quattro. Aftermarket wheels, changes in wheel width, suspension alterations, or body and fender changes can all influence whether a 225/55R17 or 245/45R18 tire still has the clearance and wheel compatibility the vehicle needs.
That is especially important on an Allroad because the page includes both 17-inch and 18-inch fitments. A modified vehicle should be checked for actual wheel diameter, wheel width, and clearance at steering lock and through suspension travel before a new tire is chosen simply because it matches the nominal size.
What should I inspect before driving a 2004 Audi Allroad Quattro on new tires?
Before driving a 2004 Audi Allroad Quattro on new tires, inspect the wheels for the correct diameter and visible damage, confirm that the tires are inflated properly, and make sure there is no rubbing at the fenders or suspension. Lug hardware should also be tightened correctly and the tire beads should be seated evenly.
A short initial road test helps confirm that the vehicle tracks properly and that nothing contacts under load or at full steering lock. It is also smart to recheck pressure after the first drives and keep an eye on any vibration, pull, or uneven wear that could point to alignment or wheel issues.
How should 225/55R17 or 245/45R18 tires on a collector 2004 Audi Allroad Quattro be maintained?
Tires on a collector 2004 Audi Allroad Quattro should be maintained with regular pressure checks, visual inspections, and attention to age-related condition even when the vehicle is not driven often. Sidewall cracking, bulges, cuts, uneven wear, and slow air loss all deserve attention before the next road outing.
Storage conditions matter on a low-use vehicle. Keeping the Allroad away from prolonged sunlight, moisture, and ozone sources helps preserve tire condition, and moving or driving the car periodically can reduce flat-spotting, especially if it spends long periods parked between uses.
