2014 Audi Trucks Tire Fitment Guide

2014 Audi Trucks vehicles use eight sizes across three models. The Q5 uses 235/60R18, 235/55R19, and 255/45R20; the Q7 uses 255/55R18, 265/50R19, 275/45R20, and 295/35R21; and the SQ5 uses 255/45R20 and 255/40R21. Only 255/45R20 overlaps, and it is shared by the Q5 and SQ5. All of these are radial sizes, but they do not mount on one common wheel diameter across the full range.

That means year and make alone are not enough for a correct match. Start by identifying whether you have a Q5, Q7, or SQ5, then confirm the wheel diameter already on the vehicle. If the SUV has had wheel changes at any point, the tire sidewall and wheel size should be checked before replacement. The correct path is always the exact size that matches the wheel package currently fitted.

On a 2014 Audi Trucks tire, 255/45R20 means the tire is 255 millimeters wide, the sidewall height is 45 percent of that width, the R indicates radial construction, and the tire mounts on a 20-inch wheel. In this model range, that size appears on both the Q5 and SQ5. It is also the one size with multiple product choices here, including Blackwall and RWL sidewall styles and W-rated performance-oriented products.

The important takeaway is that a 20-inch Audi fitment still needs the exact section width and profile, not just the same rim diameter. A Q7 can also use a 20-inch wheel, but its 20-inch tire is 275/45R20, which is a different fitment. If your sidewall reads 255/45R20, stay with that exact size unless you are making a deliberate wheel-and-tire package change with full clearance and load verification.

No, 2014 Audi Trucks models do not use the same tire size. The Q5, Q7, and SQ5 each have their own fitment patterns, and the Q5 and Q7 each span several wheel diameters depending on configuration. Only one size, 255/45R20, is shared, and that overlap is limited to the Q5 and SQ5. Every other size belongs to just one model within the range.

That model variation matters because it affects more than just width; it changes the wheel diameter, sidewall profile, and overall tire package. If you are unsure which Audi SUV you have, confirm the model badge, VIN information, and the sidewall size already mounted. Once the model is identified, selecting the correct tire becomes much more straightforward because the field of possible sizes narrows quickly.

For 2014 Audi Trucks, visible sidewall variation appears in the 255/45R20 size, where both Blackwall and RWL options are available. BFGoodrich and Nitto cover blackwall presentations in that size, while Pro-Trac offers a raised white letter version. The rest of the year-and-make size range does not show the same sidewall variety here. All of the available products in this group are radial tires intended for modern road use.

Sidewall appearance comes down to the look you want from the vehicle. A blackwall typically keeps the presentation cleaner and closer to the understated luxury character associated with Audi SUVs, while raised white letters create a more overtly performance-oriented visual statement. If appearance matters as much as fitment, compare the exact sidewall style before choosing, especially if you are replacing only two tires and want the set to remain visually consistent.

2014 Audi Trucks applications in the currently covered product range include BFGoodrich, Nitto, and Pro-Trac, all in the 255/45R20 size used by the Q5 and SQ5. BFGoodrich appears with more than one performance-oriented radial offering, Nitto adds another modern radial choice, and Pro-Trac brings an RWL option to the same size. Each of those products uses a 20-inch rim diameter and radial construction.

Brand choice usually comes after the size is settled. If your vehicle uses 255/45R20, you can compare tread style, sidewall appearance, and any load or speed markings that matter for your driving habits. If your Audi uses one of the other seven sizes, start by confirming that exact size first, because brand availability can differ sharply once you move away from the shared 20-inch Q5 and SQ5 fitment.

Within the 2014 Audi Trucks 255/45R20 fitment, BFGoodrich and Pro-Trac differ most clearly in sidewall presentation and the amount of published specification detail. BFGoodrich offers Blackwall designs in this size, with two products carrying 101W markings and one showing a rim width range of 8.0 to 9.5 inches, plus a max load figure of 1819 pounds at 51 psi on one product. Pro-Trac offers the same 255/45ZR20 sizing with an RWL sidewall and a similar published weight around 31.97 pounds.

That makes the comparison less about basic fitment and more about the look and specification emphasis you want. A buyer aiming for a clean, understated sidewall may lean toward BFGoodrich blackwalls, while someone who wants the more visible raised white letter style may prefer Pro-Trac. Before choosing between them, confirm that the wheel width and the tire's service description align with the way your Q5 or SQ5 is actually driven.

Published rim-width guidance appears here for the 2014 Audi Trucks 255/45R20 size, where BFGoodrich products specify an 8.0- to 9.5-inch rim-width range. That fitment mounts on a 20-inch wheel and is used by the Q5 and SQ5. The other sizes in the 2014 Audi Trucks range still require their own correct wheel diameters, but they do not all carry the same width guidance in the product details available here.

Rim width matters because the same tire can behave differently when stretched too narrow or too wide beyond its intended range. If your Audi uses 255/45R20, check the actual wheel width before final selection, especially if the wheels are aftermarket. For other sizes, confirm the wheel diameter first and then compare the exact product's published specifications so the tire, wheel, and intended use stay aligned.

The 2014 Audi Trucks 255/45R20 products shown here do not carry tube-type markings, and their modern radial sizing points to tubeless construction. That makes sense for contemporary Audi SUV applications using modern one-piece alloy wheels. The broader 2014 Audi Trucks range is entirely radial as well, and these fitments belong to an era when tubeless passenger and SUV tires were standard practice rather than tube-type design.

Even so, the safest habit is to verify the sidewall marking on the exact product and inspect the wheel condition before installation. A tubeless tire still depends on a sound bead seat, undamaged valve stem, and wheel free of corrosion or sealing problems. If the vehicle has custom wheels or has sat for long periods, a careful wheel inspection is just as important as choosing the correct tire size.

A 2014 Audi Trucks vehicle should be stored in a cool, dry place away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber prematurely. Keep the tires properly inflated during storage and avoid letting the vehicle sit on a damp surface for long periods. Because these are radial tires, they generally tolerate standing better than older bias-ply designs, but long static periods can still create temporary flat spotting and gradual rubber aging.

Moving the vehicle periodically helps distribute load and can reduce set-in-place wear. If the Audi will sit for an extended season, clean the tires, maintain pressure, and consider stands or cradles if the storage period is especially long. Storage habits matter just as much on a modern luxury SUV as on an older collector car, especially when the vehicle sees low annual mileage and spends more time parked than driven.

Tires on a 2014 Audi Trucks should be judged by age and condition as much as tread depth. A good rule is to begin close evaluation around five to seven years of service and to treat ten years as the point where replacement deserves serious consideration, even if the tread still looks usable. The DOT date code on the sidewall is the key reference for tire age, and low-mileage vehicles can still age out their tires before they wear them out.

That is especially relevant for Q5, Q7, and SQ5 models that may be driven infrequently or kept as second vehicles. Modern rubber compounds can harden, crack, or lose wet-weather confidence long before the tread is gone. If a 2014 Audi Trucks SUV still rides on an older set, date-code awareness is one of the smartest checks you can make before assuming the tires are fine simply because they have remaining tread.

Tires on a 2014 Audi Trucks should be inspected before every drive and especially before any extended highway trip. Look for sidewall cracking, cuts, bulges, irregular tread wear, objects embedded in the tread, and any sign that the tire is losing pressure. Since these Audi SUV fitments can vary substantially by wheel package, it is also wise to confirm that all four tires match in size where the vehicle is supposed to run a square setup.

Monthly pressure checks are a good baseline, but visual inspection should be more frequent than that. If the vehicle has been parked for weeks, inspect it before rolling out rather than after the drive has started. A quick walkaround catches many preventable problems early, and it is especially important on heavier SUVs like the Q7, where load and heat can magnify the consequences of an overlooked tire issue.

2014 Audi Trucks tires are designed around modern radial construction, and the 255/45R20 products covered here include W-rated examples with a 168 mph speed ceiling. That kind of rating sits well above normal U.S. highway speeds. In practical terms, tire condition, inflation, alignment, and the overall mechanical health of the vehicle usually matter more than the raw speed symbol during ordinary road use.

Safety still depends on choosing the exact size your Q5, Q7, or SQ5 requires and making sure all tires are in sound condition. A fresh, correctly sized radial with proper pressure is far more reassuring than an aged tire with plenty of tread left. Before any sustained highway use, check the date code, sidewalls, and pressure, and make sure the tire's service description matches the way the vehicle is actually driven.

Inflation pressure for 2014 Audi Trucks tires should start with the vehicle's factory placard or owner's manual, because Audi set pressure recommendations by model, load condition, and wheel package. Within the 255/45R20 product group, one BFGoodrich option carries a max load of 1819 pounds at 51 psi, but that figure is a tire rating limit rather than a universal operating pressure for every 2014 Audi Trucks application. Pressure should never be transferred casually from one size to another.

Use the placard pressure as the day-to-day baseline unless a tire manufacturer gives a specific approved adjustment for that fitment. Check pressure cold, not after driving, and recheck whenever temperatures swing sharply. If your Audi has changed wheels or tire size from its original configuration, pressure strategy should be reviewed carefully so the tire's load capacity and the vehicle's intended use remain in balance.

Before a longer drive in a 2014 Audi Trucks vehicle, inspect each tire for cracking, punctures, bulges, uneven wear, and proper cold inflation pressure. Confirm that the size on the vehicle matches the wheel package actually fitted, especially on Q5 and Q7 models that came with several different diameters. The spare, if present, should be checked as well, since an aged or underinflated spare is of little help when you need it.

A longer trip is also a good time to look beyond the tires and treat them as one part of a broader pre-drive check. Brakes, suspension, battery condition, fluids, and wheel fastener torque all matter on a modern Audi SUV. Tire-wise, the goal is simple: correct size, healthy sidewalls, proper pressure, and no signs of age-related deterioration that could turn a routine highway run into an avoidable roadside stop.
