2016 Audi Trucks Tire Fitment Guide

2016 Audi Trucks vehicles use six sizes across four model lines. Q3 and Q3 Quattro use 235/50R18 or 255/40R19. Q5 uses 235/60R18, 235/55R19, 255/45R20, or 255/40R21. SQ5 uses 255/45R20 or 255/40R21. Rim diameters therefore range from 18 to 21 inches, and the available rim-width guidance where published is 6.5 to 8.5 inches for 235/50R18, 8.5 to 10.0 inches for 255/40R19, and 8.0 to 9.5 inches for 255/45R20.

The practical takeaway is that 2016 Audi Trucks fitment is model-specific, not year-wide. A Q3 owner choosing between 18-inch and 19-inch fitments is solving a different problem than a Q5 or SQ5 owner working with 20-inch or 21-inch wheels. Before selecting any tire, confirm the exact model and measure the wheel diameter actually on the vehicle, especially if it has been changed from its original wheel package.

On a 2016 Audi Trucks tire, 235/50R18 is a metric radial size. The 235 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. For 2016 Audi Trucks, that size applies to the Q3 and Q3 Quattro. Available products in this size use Blackwall styling, and published rim-width guidance centers on 6.5 to 8.5 inches.

That code matters because it tells you both the tire’s proportions and the wheel size it mounts on. A buyer comparing 235/50R18 with the Q3’s optional 255/40R19 should recognize that they are not interchangeable on the same wheel. If your crossover currently wears 18-inch wheels, 235/50R18 is the size family to verify against the placard, the existing sidewall, and the wheel itself.

No, 2016 Audi Trucks models do not all use the same tire size. The Q3 and Q3 Quattro share 235/50R18 and 255/40R19, while the Q5 has its own spread of 235/60R18, 235/55R19, 255/45R20, and 255/40R21. The SQ5 shares 255/45R20 and 255/40R21 with certain Q5 configurations but does not use the Q3 sizes.

That difference is especially important because the sizes also span four wheel diameters. If you know only that you have a 2016 Audi Trucks crossover, you still have too broad a starting point to choose accurately. Identifying whether the vehicle is a Q3, Q3 Quattro, Q5, or SQ5 is the first step, and confirming the current wheel package is the second.

2016 Audi Trucks tires are primarily available in Blackwall form, which appears across 235/50R18, 255/40R19, and many 255/45R20 products. The one sidewall variation in this grouping is 255/45R20, which is also available with RWL styling. All of these sizes are modern radial fitments, so the sidewall decision is mainly about appearance rather than an era-correct bias-ply versus radial choice.

Most buyers restoring or maintaining a 2016 Audi Trucks crossover to factory-style appearance will gravitate toward Blackwall because it aligns with how modern premium SUVs are commonly presented. RWL gives the 20-inch shared Q5 and SQ5 size a more custom or enthusiast-oriented visual effect. If appearance matters as much as fitment, decide on sidewall style after you confirm the exact tire size and wheel diameter.

BFGoodrich, Nitto, and Pro-Trac all cover portions of the 2016 Audi Trucks range. The 235/50R18 size is available from BFGoodrich and Nitto, 255/40R19 is covered by BFGoodrich, and 255/45R20 is available from BFGoodrich, Nitto, and Pro-Trac. These offerings stay within modern radial construction and focus on replacement fitments for late-model crossover wheel packages.

Brand choice becomes more meaningful after the size is settled, because the same make does not cover every 2016 Audi Trucks fitment equally. Q3 owners have a different brand mix than Q5 or SQ5 owners running 20-inch tires. Once the model and size are confirmed, compare the available sidewall style, speed rating, and any published load information rather than assuming every brand offers the same specification.

For 2016 Audi Trucks applications where both are offered, the BFGoodrich g-Force Sport COMP-2 and Nitto NT555 G2 share radial construction, Blackwall styling, and W speed ratings. In 235/50R18, both fit 18-inch wheels and both work within a 6.5 to 8.5-inch rim-width range, while the Nitto version carries an XL 101W marking and a published max load of 1,819 pounds at 50 psi. In 255/45R20, both mount on 20-inch wheels, and the Nitto again carries an XL 105W marking.

The useful comparison for a buyer is not that one is universally right and the other is wrong, but that they can differ in load marking, weight, and exact fitment details even when the base size is the same. If you are comparing them for a Q3, Q5, or SQ5 application, check the specific sidewall marking and wheel-width suitability on the tire you are considering rather than relying only on the nominal size code.

Published rim-width guidance for 2016 Audi Trucks tires varies by size. The 235/50R18 fits a 6.5 to 8.5-inch wheel, the 255/40R19 fits an 8.5 to 10.0-inch wheel, and the 255/45R20 fits an 8.0 to 9.5-inch wheel. Those ranges match the wheel diameter associated with each size and help confirm whether an existing wheel is suitable for the tire being considered.

Rim width matters because two tires with the same wheel diameter can still call for different wheel widths to support their intended profile correctly. If your 2016 Audi Trucks crossover has aftermarket wheels, verify both the wheel diameter and the actual wheel width before choosing a tire. That step is especially important on wider low-profile sizes, where appearance and handling can change noticeably when the wheel falls outside the intended range.

2016 Audi Trucks tires in these sizes are tubeless rather than tube-type. The 255/40R19 includes a product marked TL, and the overall size family is made up of modern radial crossover and performance tires rather than vintage tube-type constructions. That aligns with what you would expect on a 2016 Audi Trucks Q3, Q5, or SQ5 using contemporary one-piece road wheels.

Even so, tubeless operation still depends on wheel condition and valve-stem integrity. If a 2016 Audi Trucks vehicle has damaged bead seats, corroded wheels, or worn valve stems, a tubeless tire may still leak air even when the size is correct. During installation, have the wheel inspected carefully and replace service items such as valve stems so the new tire can seal as intended.

A 2016 Audi Trucks crossover should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate rubber aging. Keep the tires clean, maintain inflation, and avoid long periods parked on wet concrete or in standing moisture. Radial tires generally tolerate storage better than older bias-ply designs, but they still age from heat, UV exposure, and neglect.

If the vehicle will sit for extended periods, move it occasionally to change the contact patch or place it on stands if the storage plan and suspension considerations allow. Owners who use a 2016 Audi Trucks vehicle seasonally should also check pressures before returning it to service, since a slow loss of air during storage can stress the sidewall and create an uneven footprint.

On a 2016 Audi Trucks vehicle, tire age usually matters more than collector-style low mileage. A sound rule is to begin evaluating tires closely around five to seven years of age and to treat about ten years as a serious replacement point regardless of remaining tread. The DOT date code on the sidewall is the best way to identify the tire’s age, and that matters even if the crossover has been driven sparingly.

Luxury crossovers often accumulate uneven wear patterns, seasonal use, or long storage intervals that can make an older tire look better than it really is. If your 2016 Audi Trucks vehicle still wears tires with ample tread but noticeable hardening, weather checking, vibration, or repeated pressure loss, age has become the deciding factor. A fresh set is usually wiser than stretching service life simply because the tread depth still appears acceptable.

Tires on a 2016 Audi Trucks should be inspected before every drive and given a more thorough check before any extended highway trip. Look for sidewall cracking, cuts, bulges, irregular tread wear, embedded debris, and changes in air pressure retention. Because these are tubeless radial sizes, also inspect the valve stems and wheel sealing surfaces whenever a tire is removed or if a slow leak develops.

Frequent inspection is especially important on vehicles that alternate between daily use and long idle periods, which is common with second-owner premium SUVs. A 2016 Audi Trucks crossover can feel normal around town while still hiding a tire issue that shows up only at sustained speed. Catching a failing valve stem, damaged shoulder, or uneven wear early is far easier than dealing with a vibration or roadside problem later.

A 2016 Audi Trucks Q3 would have been fitted from the factory with modern radial tires in metric sizing, not vintage-style bias-ply construction. Within this year-and-make range, the Q3 and Q3 Quattro use 235/50R18 or 255/40R19, depending on wheel package. Those sizes reflect contemporary luxury-crossover practice, with low-profile radial construction matched to larger-diameter alloy wheels rather than the taller sidewalls seen on earlier eras.

For a factory-style restoration or careful OEM-style refresh, the key is matching the correct size, wheel diameter, and sidewall appearance for the specific configuration on the vehicle. Blackwall remains the closest visual match for most original presentations. If the crossover has changed hands or received wheel upgrades, verify against the placard, original sales literature, or an Audi marque specialist before deciding which of the two Q3 sizes belongs on your example.

Correct tire fitment does matter when showing a 2016 Audi Trucks vehicle, even though these are modern rather than prewar or muscle-era applications. Judges and knowledgeable enthusiasts often notice whether the wheel diameter, tire size, profile, and sidewall appearance suit the model and trim level. A Q3 wearing a size meant for a Q5, or an SQ5 wearing an obviously incorrect sidewall treatment, can distract from an otherwise sharp presentation.

For a show-minded owner, accuracy usually means confirming what wheel package the vehicle was delivered with and choosing a tire that preserves the right overall look. On 2016 Audi Trucks crossovers, that often comes down to proper metric sizing and restrained sidewall styling rather than brand-correct vintage detailing. Event standards vary, so owners aiming for marque-specific judging should compare their setup against club resources and factory reference material.

For 2016 Audi Trucks fitments where both appear, the BFGoodrich g-Force Phenom T/A and BFGoodrich g-Force COMP-2 A/S share radial construction and Blackwall styling, but they differ in some published details. In 235/50R18, the Phenom T/A carries a 101W marking with a published 1,819-pound load at 50 psi and weighs 29.01 pounds, while the COMP-2 A/S appears in a 97W form at 29 pounds. In 255/40R19, the Phenom T/A appears as a 100Y tire, while the COMP-2 A/S appears in 100W and 100Y forms.

That means the choice is less about visible style and more about the exact specification that suits your vehicle’s use and wheel package. A buyer comparing these for a Q3 application should read the full sidewall code, not just the series name. When two products share the same nominal size but differ in speed symbol, load marking, or weight, those details are worth confirming before settling on one.

2016 Audi Trucks tires in these sizes are highway-capable modern radials, and the available speed ratings include W and Y depending on size and product. W-rated tires are rated to 168 mph, while Y-rated tires are rated to 186 mph or higher. Those numbers exceed normal U.S. highway speeds by a wide margin, so in ordinary driving the condition of the tire, correct inflation, and the vehicle’s overall mechanical health matter more than the top speed symbol alone.

Safety on a longer road trip still depends on matching the correct size to the model, maintaining the proper pressure, and inspecting for age-related cracking or impact damage. A 2016 Audi Trucks crossover with worn suspension parts, poor alignment, or old tires can feel unsettled even if the speed rating looks generous on paper. Choose a tire whose size and service description suit the vehicle first, then keep the rest of the chassis in equally sound condition.

Inflation pressure for 2016 Audi Trucks should start with the factory recommendation for the exact model, axle load, and wheel package, because 235/50R18, 255/40R19, and 255/45R20 do not all carry the same service details. Published maximum load and pressure figures in this group include 1,609 pounds at 51 psi and 1,819 pounds at 50 psi for 235/50R18 products, 1,764 pounds at 50 psi for certain 255/40R19 products, and 1,819 pounds at 51 psi for a 255/45R20 product.

Those figures are not the same thing as the vehicle’s everyday operating pressure. Use the door-jamb placard or owner’s manual for normal service settings, then compare them with the sidewall information on the specific tire you choose. Never transfer a pressure figure from one 2016 Audi Trucks size to another simply because the vehicles are from the same year, since wheel diameter, aspect ratio, and load index can all change the right setup.

Before taking a 2016 Audi Trucks on a longer drive, inspect all four tires and the spare for tread condition, sidewall cuts, bulges, punctures, and signs of age cracking. Confirm cold inflation pressures, look for uneven wear that could point to alignment or suspension issues, and make sure the valve stems are in good shape. If the vehicle has sat for a while, also check for vibration-causing flat spotting and confirm that each wheel still holds pressure evenly.

That tire check should be part of a broader mechanical inspection appropriate for any modern premium SUV that may not be driven daily. Brakes, battery condition, fluids, and lighting deserve attention too, but the tire inspection is the part that directly affects road contact from the first mile. On a 2016 Audi Trucks vehicle with optional larger wheels, damage from potholes or curb strikes also deserves a careful look before highway use.
