The 2013 Audi Trucks Q7 sits in the modern luxury SUV era where everyday comfort, all-weather confidence, and upscale road manners all had to coexist with substantial size and weight. As a three-row Audi utility vehicle, it asks more from its tires than a lighter passenger car, especially when wheel packages change across trims. Tire fitment on the 2013 Audi Trucks Q7 is entirely radial, but the exact size ranges from 255/55R18 up to 295/35R21 depending on sub-model and wheel option. That means the real decision is not simply brand selection, but confirming the correct rim diameter, sidewall profile, and trim-specific fitment before replacing a tire set.
Which Tire Size Is Right for The 2013 Audi Trucks Q7
The 2013 Audi Trucks Q7 uses four primary tire sizes, and they vary by sub-model and wheel package. Those sizes also span four different rim diameters, from 18-inch through 21-inch fitments, so the first step is confirming the exact sub-model and wheel size on the vehicle before choosing a replacement tire.
255/55R18 is a metric radial size in which 255 refers to section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2013 Audi Trucks Q7, this size represents one of the taller-sidewall factory-style fitments in the lineup. Its profile balances modern SUV road use with more sidewall than the larger-diameter wheel packages. This size is the right place to start when the vehicle is equipped with 18-inch wheels and you want to preserve the intended wheel-to-tire relationship rather than moving into a lower-profile package.
Fit(s): Premium, Premium Plus (19 Inch Option), TDI Premium, and TDI Premium Plus
Construction: Radial|Rim: 19 in
265/50R19 is a metric radial size with a 265-millimeter nominal section width, a 50-series profile, and fitment on a 19-inch rim. For the 2013 Audi Trucks Q7, it serves as a middle-ground size used on several configurations, adding width while still keeping a practical sidewall height for a luxury SUV. It is a useful fitment to evaluate when the Q7 has 19-inch wheels and you want to maintain the proportions intended for that setup. Wheel diameter should be confirmed first, since this size is not interchangeable with the Q7's 18-, 20-, or 21-inch fitments.
Fit(s): Premium Plus (20 Inch Option), Prestige, TDI Premium, TDI Premium Plus, and TDI Prestige
Construction: Radial|Rim: 20 in
275/45R20 follows the same metric radial format, with 275 indicating nominal width in millimeters, 45 indicating the aspect ratio, and 20 identifying the rim diameter. On the 2013 Audi Trucks Q7, this size appears on several upper-level and diesel-related configurations, making it one of the most widely used larger-wheel fitments in the range. Its lower profile creates a distinctly different wheel-and-tire package than the 18-inch and 19-inch sizes. It should be selected only when the vehicle is already set up for a 20-inch rim package and the surrounding wheel and clearance setup matches that fitment.
295/35R21 is a metric radial size that combines a 295-millimeter nominal width with a 35-series profile on a 21-inch rim. For the 2013 Audi Trucks Q7, this is the largest wheel-package fitment in the range and it delivers the lowest-profile appearance among the primary sizes used on this model. That makes it a trim-specific choice rather than a universal Q7 replacement size. Owners should evaluate it carefully against the actual wheel package on the vehicle, since moving into or out of a 21-inch setup changes both rim diameter and overall tire profile compared with the smaller factory fitments.
Tire fitment on the 2013 Audi Trucks Q7 varies meaningfully by sub-model and by wheel option within certain trims. Checking the exact trim level and installed wheel diameter matters before choosing a replacement, because the Q7 spans four distinct radial sizes across the model range.

2013 Audi Trucks Q7 Premium
The 2013 Audi Trucks Q7 Premium uses either 255/55R18 or 265/50R19, so tire selection starts with confirming whether the vehicle has the 18-inch or 19-inch wheel package. Once that is established, the main goal is matching the correct metric radial size rather than choosing between constructions.
The 2013 Audi Trucks Q7 Premium Plus uses 255/55R18 in its standard form. That makes replacement relatively straightforward, with the key checks centered on keeping the proper 18-inch radial size and confirming that the vehicle has not been changed to a different wheel package.
The 2013 Audi Trucks Q7 Premium Plus (19 Inch Option) uses 265/50R19. Tire selection here depends on retaining the correct 19-inch metric radial fitment and not assuming that the standard Premium Plus 18-inch size still applies.
The 2013 Audi Trucks Q7 Premium Plus (20 Inch Option) uses 275/45R20. This configuration requires attention to the 20-inch wheel setup, since its lower-profile tire package differs substantially from the 18-inch and 19-inch versions of the Q7.
The 2013 Audi Trucks Q7 Prestige can use either 275/45R20 or 295/35R21 depending on wheel package. Replacing tires on this trim starts with confirming whether the vehicle carries the 20-inch or 21-inch setup, because the two sizes are not the same fitment decision.
The 2013 Audi Trucks Q7 TDI Premium uses either 265/50R19 or 275/45R20. That means the correct replacement depends on the actual wheel diameter on the vehicle, with tire choice focused on matching the installed radial package.
The 2013 Audi Trucks Q7 TDI Premium Plus can be equipped with 265/50R19 or 275/45R20 tires. Owners should confirm the current wheel size first, then choose the appropriate metric radial replacement that matches that configuration.
The 2013 Audi Trucks Q7 TDI Prestige uses either 275/45R20 or 295/35R21. The practical selection step is verifying whether the vehicle is on the 20-inch or 21-inch wheel package before comparing replacement tires.
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.
Frequently Asked Questions
Owners of a 2013 Audi Trucks Q7 usually need to sort out exact tire size by trim and wheel package first. These FAQs focus on fitment, rim diameter, tire selection, appearance differences between wheel packages, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2013 Audi Trucks Q7?
The 2013 Audi Trucks Q7 uses four primary tire sizes: 255/55R18, 265/50R19, 275/45R20, and 295/35R21. The correct size depends on the exact sub-model and wheel package, so there is not one universal tire size for every 2013 Q7 configuration.
The most important step is matching the tire to the wheel diameter already on the vehicle. A Q7 equipped with 18-inch wheels needs a different tire than one equipped with 20-inch or 21-inch wheels, and the trim name alone may not be enough if an optional wheel package was used.
What size rim does a 2013 Audi Trucks Q7 use?
A 2013 Audi Trucks Q7 can use 18-inch, 19-inch, 20-inch, or 21-inch rims depending on the trim and wheel option. Those rim diameters correspond to the tire sizes 255/55R18, 265/50R19, 275/45R20, and 295/35R21.
The last number in each tire size is the rim diameter, and it must match the wheel exactly. Before replacing tires, confirm the actual wheel size on the vehicle rather than assuming every Q7 in this model year shares the same rim, especially on Premium, Prestige, and TDI variants with multiple fitment possibilities.
Why does the 2013 Audi Trucks Q7 have more than one tire size?
The 2013 Audi Trucks Q7 was offered with different trims and wheel packages, which is why it uses more than one tire size. Some versions carry 18-inch or 19-inch wheels, while others move to 20-inch or 21-inch fitments with lower-profile radial tires.
That variation means the replacement decision starts with the exact configuration on the vehicle, not just the model name. Checking the trim badge helps, but the installed wheel diameter is the deciding factor because it determines which of the four approved tire sizes belongs on that particular Q7 setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Audi Trucks Q7?
Start with the correct size for the specific 2013 Audi Trucks Q7 sub-model and wheel package, since this vehicle uses 18-inch, 19-inch, 20-inch, and 21-inch fitments. The tire must match the installed rim diameter and the intended size for that configuration before any other selection factors come into play.
After size is confirmed, compare the overall tire profile the vehicle is already built around. An 18-inch Q7 setup carries a different sidewall shape than a 21-inch setup, so replacement should follow the existing wheel-and-tire package unless the vehicle is being reconfigured with careful attention to wheel compatibility and body clearance.
How do I choose between the available 2013 Audi Trucks Q7 tire sizes?
The available tire sizes are not interchangeable choices for a single setup; they correspond to different Q7 trims and wheel diameters. A 255/55R18 belongs with an 18-inch package, while 265/50R19, 275/45R20, and 295/35R21 each belong with their own wheel size.
Choosing between them really means confirming what is already on the vehicle. Check the current tire sidewall, verify the wheel diameter, and compare that against the trim and option package so the replacement keeps the same basic proportions and avoids moving into a different fitment range by mistake.
What tire series are available for the 2013 Audi Trucks Q7?
Tire-series details are less important on the 2013 Audi Trucks Q7 page than confirming the exact radial size tied to the vehicle's wheel package. The larger fitment story here is built around the four metric sizes and the different rim diameters used across Premium, Prestige, and TDI configurations.
For most owners, the better comparison points are wheel size, sidewall profile, and whether the vehicle is on its original trim-specific setup. Once the correct size is established, series-level product comparison becomes more meaningful because it happens within the proper fitment rather than across unrelated 18-inch through 21-inch packages.
Restoration & Appearance
Does correct tire fitment matter for a 2013 Audi Trucks Q7 restoration or refurbishment?
Yes, correct tire fitment matters on a 2013 Audi Trucks Q7 because the vehicle's stance and overall look change noticeably across its 18-inch, 19-inch, 20-inch, and 21-inch wheel packages. Using the proper size helps preserve the intended relationship between the wheel, sidewall, and body.
A refurbishment-focused owner should confirm which trim-specific or option-specific setup the vehicle is meant to carry before replacing tires. That is especially important on trims such as Premium Plus, Prestige, and TDI models, where wheel-package changes alter both the sidewall profile and the visual character of the Q7.
How does tire size affect the appearance of a 2013 Audi Trucks Q7?
Tire size affects the appearance of a 2013 Audi Trucks Q7 by changing the balance between wheel diameter and sidewall height. A 255/55R18 setup presents more sidewall, while a 295/35R21 setup creates a larger-wheel, lower-profile look that feels distinctly different on the same body shape.
That visual change is one reason the exact fitment should be confirmed before replacement. Owners trying to maintain a trim-appropriate presentation usually want to stay with the wheel-and-tire package the vehicle already wears, rather than mixing a tire size from another Q7 configuration without checking the full wheel setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Audi Trucks Q7?
Yes, modifications can affect tire fitment on a 2013 Audi Trucks Q7. Aftermarket wheels, suspension changes, ride-height changes, or previous wheel-package swaps can alter which tire size is actually on the vehicle and can change the clearance relationship around the fenders and steering components.
That makes it important to inspect the current setup instead of relying only on the original trim description. Measure the wheel diameter, confirm the tire size printed on the sidewall, and look for signs that the vehicle has moved from an 18-inch, 19-inch, 20-inch, or 21-inch factory-style package to something different.
What should I inspect before driving a 2013 Audi Trucks Q7 on new tires?
Before regular road use, inspect the wheel size, confirm the new tires match the intended Q7 fitment, and make sure each tire is mounted on the correct rim diameter. It is also wise to check inflation, look over the wheels for damage, and verify that nothing rubs during steering or suspension movement.
A heavier luxury SUV places real demands on its tires, so a short initial check drive is worthwhile after installation. Pay attention to vibration, pulling, unusual noise, or contact at full steering lock, especially if the vehicle has larger wheel packages or has ever been altered from its original trim-specific setup.
How often should tires on a 2013 Audi Trucks Q7 be inspected?
Tires on a 2013 Audi Trucks Q7 should be inspected regularly, with extra attention before longer highway use and whenever seasonal conditions change. Look for uneven wear, sidewall damage, punctures, abnormal air loss, and any signs that the tread is aging or the vehicle is not wearing the tires evenly.
Routine inspection matters because the Q7 uses several low-profile wheel-and-tire packages where condition can change without being obvious at a glance. Owners should also confirm that all four tires remain the same size and fitment type intended for the vehicle, particularly after service work, wheel replacement, or used-vehicle purchase.
