2013 Audi Trucks Tire Fitment Guide

2013 Audi Trucks vehicles use seven radial tire sizes across two models. The Q5 uses 235/60R18, 235/55R19, and 255/45R20, while the Q7 uses 255/55R18, 265/50R19, 275/45R20, and 295/35R21. Rim diameters span 18 through 21 inches across the year and make, so there is no single size that fits both models.

That means year and make alone are not enough to choose a tire for 2013 Audi Trucks. Start by identifying whether you have a Q5 or Q7, then verify the wheel diameter actually installed on the vehicle. If a previous owner changed wheels, the tire currently fitted may not match the size originally associated with your model, so checking the sidewall and the wheel itself is the safest starting point.

On a 2013 Audi Trucks tire, 235/55R19 is a metric radial size code. The 235 is the nominal section width in millimeters, 55 is the aspect ratio, meaning the sidewall height is 55 percent of the width, R identifies radial construction, and 19 is the wheel diameter in inches. For 2013 Audi Trucks, this size applies to the Q5.

Reading the code that way helps separate sizes that may look similar at a glance but mount on different wheels or have different overall proportions. A 235/55R19 is not interchangeable with a 235/60R18 just because both begin with 235. On a Q5, that difference affects the wheel diameter first, then the tire profile, so the full code matters every time you compare replacements.

No, 2013 Audi Trucks models do not use the same tire size. The Q5 has three radial sizes—235/60R18, 235/55R19, and 255/45R20—while the Q7 has four different radial sizes—255/55R18, 265/50R19, 275/45R20, and 295/35R21. None of those sizes are shared across both models.

That separation matters because the correct tire choice depends on model identity and wheel package, not just on the fact that both vehicles came from Audi in the same year. The Q7 generally uses wider and sometimes larger-diameter fitments than the Q5, so moving straight to a product without confirming model and wheel size can lead you into the wrong category very quickly.

Sidewall style coverage for 2013 Audi Trucks varies by size. In the 255/45R20 fitment used on the Q5, Blackwall and raised white letter options both appear, depending on the product. Blackwall is the more understated modern luxury-SUV look, while RWL adds a more assertive performance-oriented appearance.

Choosing between them comes down mostly to appearance and how closely you want the tire to match the character of your vehicle. A Q5 with factory-style visual restraint usually looks most at home on a Blackwall tire, while an owner building a more individualized 20-inch setup may prefer the RWL look. Sidewall style should be confirmed alongside the size code, since the same size can carry more than one appearance.

BFGoodrich, Nitto, and Pro-Trac all cover 2013 Audi Trucks in the available 255/45R20 Q5 fitment. BFGoodrich appears in more than one series in that size, while Nitto and Pro-Trac add alternate choices with different sidewall presentation and service descriptions. Every available product in that fitment is a radial.

Brand choice becomes more useful once your size is already confirmed, because it lets you compare the kind of look and specification that best matches your intended use. Some owners prioritize a familiar performance-oriented name, while others focus on a particular sidewall style. The important thing is to keep the comparison inside the correct size for your model rather than treating all 2013 Audi Trucks tires as interchangeable.

For the 2013 Audi Trucks Q5 in 255/45R20, BFGoodrich offers both the g-Force COMP-2 A/S and the g-Force Sport COMP-2. Both use the same 255/45ZR20 size, both carry a 101W service description in the examples shown, both are Blackwall radials, and both fit 20-inch wheels with an 8.0 to 9.5 inch rim width range. The g-Force Sport COMP-2 also carries a stated maximum load figure of 1819 pounds at 51 psi.

That means the practical comparison is less about basic fitment and more about choosing the exact series you want within the same size family. Since the dimensions and sidewall presentation align closely, the decision should be made by matching the product series and service details to how the vehicle is used. Confirm the full sidewall marking before finalizing, especially if you are comparing multiple 255/45R20 performance-style products.

Rim width guidance is available for the 255/45R20 fitment used on the 2013 Audi Trucks Q5. In that size, some products fit a rim width range of 8.0 to 9.5 inches, paired with a 20-inch rim diameter. That range applies to the products carrying that specification in 255/45R20 and should not be transferred automatically to the other Audi sizes.

Rim width matters because the same overall tire size can behave differently when mounted on a wheel that is too narrow or too wide for the intended application. Before replacing tires on a Q5 with 20-inch wheels, confirm the actual wheel width stamped on the rim or verify it through a trusted wheel reference. Matching the tire to both diameter and width is the cleanest way to avoid fitment surprises.

The available 255/45R20 products for 2013 Audi Trucks do not carry tube-type markings, and their modern radial construction aligns with tubeless use on appropriate wheels. The sidewall markings shown for that size use standard passenger performance nomenclature rather than TT designations. Across the rest of the 2013 Audi Trucks sizes, tube use should follow the exact sidewall marking of the tire and the construction of the wheel.

For a 2013 Q5 or Q7 on original-style modern wheels, tubeless radial fitment is generally the expectation, but the final check still belongs at the tire and wheel level. If a wheel has been changed, repaired, or refinished, confirm that it is suitable for tubeless service and that the valve hardware is in good condition. That is especially important on vehicles that spend long periods parked between drives.

A 2013 Audi Trucks vehicle should be stored away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age the rubber prematurely. Keep the tires clean and dry, maintain inflation, and move the vehicle periodically so one section of the tread is not carrying the load in the same spot for months at a time. Radial tires resist long-term flat-spotting better than old bias-ply designs, but they still benefit from thoughtful storage.

For a Q5 or Q7 that sees occasional use, storage habits often affect tire condition more than mileage does. If the vehicle will sit for an extended period, many owners either roll it occasionally or support it in a way that reduces static load, while still following safe lifting practices. Good storage helps preserve ride quality, sidewall appearance, and pressure retention when the vehicle goes back on the road.

On a 2013 Audi Trucks vehicle, tire life should be judged by age and condition as much as by tread depth. A sensible collector and low-mileage guideline is to begin evaluating tires closely at about five to seven years of age and to treat around ten years as a serious replacement consideration, even if the tread still looks usable. The DOT date code on the sidewall is the starting point for that timeline.

Luxury SUVs like the Q5 and Q7 can accumulate relatively little mileage while still aging their tires through heat cycles, weather exposure, and time under load. A tire that looks acceptable from a distance may still be too old for confident use on highway trips. If the age is creeping up, pair the date-code check with a close inspection for cracking, hardening, and any loss of uniformity in the tread or sidewall.

Tires on a 2013 Audi Trucks vehicle should be inspected before every drive and especially before any longer outing. Check inflation pressure, look for cuts, bulges, cracking, uneven wear, and objects embedded in the tread, and make sure the sidewalls remain free of impact damage. On a modern SUV with larger wheel packages, even small sidewall damage deserves attention because lower-profile sizes can hide little margin for error.

That routine is especially valuable on vehicles that alternate between daily use and long parked intervals. A Q5 or Q7 that has been sitting may have lost pressure or developed subtle issues that were not present on the last drive. A quick visual inspection plus a pressure check takes only a few minutes and can prevent a much bigger problem once the vehicle is at highway speed.

2013 Audi Trucks tires are suitable for highway driving when they are the correct size, in sound condition, and used within their service description. In the available 255/45R20 fitment for the Q5, W-rated products appear, which corresponds to a 168 mph speed ceiling under controlled conditions. That number is far beyond normal U.S. highway use, so the more important real-world factors are tire age, inflation, condition, and the overall mechanical health of the vehicle.

For a Q5 or Q7, highway confidence comes from the whole package rather than from the speed symbol alone. Suspension condition, alignment, brakes, and wheel integrity all matter alongside the tires. If a vehicle has been in storage or recently returned to service, treat the first longer drive as a recommissioning exercise and inspect everything carefully instead of assuming a modern-looking radial is automatically ready for extended high-speed use.

Inflation pressure on 2013 Audi Trucks tires should follow the vehicle placard or owner’s manual first, then be checked against the service details of the exact tire being used. In the available 255/45R20 fitment, one product carries a maximum load of 1819 pounds at 51 psi, but that figure is the tire’s rated maximum and not a blanket operating pressure for every 2013 Audi Trucks application or every size.

That distinction matters because a maximum pressure molded into the tire and a vehicle manufacturer’s recommended operating pressure serve different purposes. Use the Audi recommendation as your baseline for normal driving, load, and ride balance, then confirm that the tire you choose meets the required load and speed service for your vehicle. Never copy a pressure figure from one size to another just because the wheel diameter looks similar.

Before taking a 2013 Audi Trucks vehicle on a longer drive, inspect each tire for cracking, punctures, bulges, unusual wear, and any signs of impact damage from curbs or potholes. Check cold inflation pressure, confirm the spare is usable, and make sure valve stems and caps are in good condition. On larger-diameter Q5 and Q7 wheel packages, also pay attention to the inner sidewall where damage can be less obvious at a quick glance.

Tires are only one part of the pre-trip check on a modern luxury SUV, but they are the easiest place to catch a problem before it becomes inconvenient or dangerous. Pair the tire inspection with a walkaround of the wheels, brakes, and fluid condition, especially if the vehicle has sat unused. A few extra minutes in the garage can make a long drive in a 2013 Audi Trucks far more predictable and enjoyable.
