The 2016 Audi Trucks SQ5 brought sport-sedan urgency into a compact luxury utility shape, pairing Audi performance character with a taller, more versatile platform. Buyers looking at one today are often balancing that modern performance feel with the realities of wheel and tire setup. The 2016 Audi Trucks SQ5 uses radial tires, with 255/45R20 and 255/40R21 fitments depending on wheel diameter. That creates a more specific decision around confirming whether the vehicle is on 20-inch or 21-inch wheels, then comparing available tire series and sidewall treatments within the correct size. For an SQ5 that is driven regularly, appearance, wheel compatibility, and clearance all deserve equal attention.
Which Tire Size Is Right for The 2016 Audi Trucks SQ5
The 2016 Audi Trucks SQ5 uses two primary tire sizes, and both are radial fitments. The key difference is wheel diameter, since one size fits a 20-inch rim and the other fits a 21-inch rim. Both Premium Plus and Prestige models can use either size, so the first step is confirming which wheel package is actually on the vehicle before choosing a tire.
255/40R21 is a metric radial size in which 255 identifies the nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 21 is the rim diameter in inches. On the 2016 Audi Trucks SQ5, this size suits the 21-inch wheel setup and keeps the vehicle in a distinctly modern performance-oriented sizing format. Its practical role is straightforward: if the SQ5 is wearing 21-inch wheels, this is the size to verify. Wheel width, clearance, and any prior wheel changes should still be checked before final selection.
255/45R20 is a metric radial size with a 255-millimeter nominal section width, a 45-series profile, radial construction, and a 20-inch rim diameter. For the 2016 Audi Trucks SQ5, this size is tied to the 20-inch wheel package and offers the broadest visible product choice, including BFGoodrich, Nitto, and Pro-Trac offerings. Available examples include Blackwall, raised white letter, and Redline sidewall treatments across different tire series. This size deserves closer comparison if the vehicle is on 20-inch wheels and appearance is part of the decision along with general road use.
Tire fitment is straightforward across the covered 2016 Audi Trucks SQ5 sub-models because both Premium Plus and Prestige can use the same two radial sizes. The important step is not trim level alone, but confirming whether the vehicle is equipped with 20-inch or 21-inch wheels.

Available 255/45R20 choices for the 2016 Audi Trucks SQ5 include BFGoodrich, Nitto, and Pro-Trac radial tires. The main comparison points are tire series, Blackwall versus raised white letter or Redline sidewalls, and rim-width specifications where stated.
SQ5 owners usually need to sort out wheel diameter first, then compare tire size, sidewall style, and product series. These FAQs focus on exact fitment, 20-inch versus 21-inch setups, tire selection, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2016 Audi Trucks SQ5?
The 2016 Audi Trucks SQ5 uses two primary tire sizes: 255/45R20 and 255/40R21. Both are radial fitments, and the correct choice depends on which wheel diameter is on the vehicle rather than on a simple one-size-fits-all rule for every SQ5.
The practical next step is to confirm whether the vehicle is wearing 20-inch or 21-inch wheels before selecting a tire. Premium Plus and Prestige models can use either size, so trim name alone is not enough. If the SQ5 has been changed from its original wheel setup, check the actual wheel diameter and width on the vehicle before buying tires.
What size rim does a 2016 Audi Trucks SQ5 use?
A 2016 Audi Trucks SQ5 uses either a 20-inch or 21-inch rim, depending on the wheel package. The 255/45R20 tire fits the 20-inch setup, while the 255/40R21 tire fits the 21-inch setup.
Rim diameter is the first fitment detail to verify because these two tire sizes are not interchangeable across different wheel diameters. It also helps to confirm wheel width, especially if the vehicle has aftermarket wheels. A quick check of the sidewall size already on the vehicle, along with the wheel markings, can prevent choosing the right tire size for the wrong rim.
Do all 2016 Audi Trucks SQ5 sub-models use the same tire size?
Both the 2016 Audi Trucks SQ5 Premium Plus and Prestige can use the same two tire sizes: 255/45R20 and 255/40R21. The fitment pattern is shared across those sub-models, but the actual size on a specific vehicle still depends on the wheel diameter installed.
That means tire selection is more about confirming the wheel setup than sorting between Premium Plus and Prestige trim names. A buyer should not assume that every SQ5 of this year is on the same wheels. Looking at the tire sidewall, measuring rim diameter, and noting any previous wheel changes will keep the purchase focused on the size the vehicle actually uses.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2016 Audi Trucks SQ5?
Start with the basic fitment points: 255/45R20 size, radial construction, and a 20-inch wheel. From there, the choice shifts to product character, since this size is available in several series from BFGoodrich, Nitto, and Pro-Trac, with differences in sidewall styling and some stated rim-width specifications.
The best comparison points are the look you want, the wheel width on the vehicle, and how the SQ5 is used. A Blackwall tire gives a more understated presentation, while raised white letter or Redline sidewalls create a stronger visual statement. It also helps to compare stated load figures where available, along with tire weight and any wheel changes already made to the vehicle.
What sidewall styles are available for 2016 Audi Trucks SQ5 tires?
For the 2016 Audi Trucks SQ5 in 255/45R20, available sidewall styles include Blackwall, RWL, and Redline. Blackwall appears across several offerings, while Pro-Trac Street Pro III is available in both raised white letter and Redline versions.
That sidewall choice mainly affects appearance rather than the basic size fitment. A Blackwall tire suits a cleaner modern look, while RWL or Redline gives the SQ5 a more expressive visual character. Once the correct 20-inch size is confirmed, sidewall style becomes a useful way to narrow the field without changing the vehicle’s primary tire dimensions.
What brands offer tires for the 2016 Audi Trucks SQ5?
In 255/45R20, the 2016 Audi Trucks SQ5 has tire options from BFGoodrich, Nitto, and Pro-Trac. Those brands appear across several radial tire series, giving the buyer more than one path depending on preferred styling and product details.
Brand alone should not be the only filter. It is better to compare the exact tire series, sidewall treatment, and wheel compatibility details within the correct size. On a vehicle like the SQ5, which may already have wheel upgrades or prior replacement tires, confirming the actual wheel setup first keeps the brand comparison focused on options that match the vehicle’s current configuration.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Audi Trucks SQ5?
A period-style 2016 Audi Trucks SQ5 still begins with the correct modern radial size for the wheel diameter on the vehicle: either 255/45R20 or 255/40R21. Within the visible 255/45R20 product range, the tire choice becomes more about presentation, tire series, and whether a subtle or more assertive sidewall look suits the vehicle.
For a cleaner contemporary appearance, Blackwall options keep the look restrained. Redline or raised white letter sidewalls create a stronger custom visual statement without changing the basic size category. Since this is a modern performance utility rather than a traditional restoration-era car, the goal is usually a wheel-and-tire combination that looks appropriate to the vehicle rather than chasing strict originality language.
How does tire construction affect the appearance of a restored 2016 Audi Trucks SQ5?
On the 2016 Audi Trucks SQ5, the primary fitments are radial tires, so construction does not create a bias-ply versus radial visual decision. Appearance is shaped more by wheel diameter, sidewall profile, and sidewall styling, especially if the vehicle uses the 255/45R20 size where Blackwall, RWL, and Redline options are available.
That means the visual character of the SQ5 comes from how the tire complements the wheel package already on the vehicle. A 20-inch setup with a more expressive sidewall treatment can give the vehicle a different presence than a simpler Blackwall presentation. Matching the tire’s look to the SQ5’s intended finish matters more here than trying to mimic an older construction style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Audi Trucks SQ5?
Yes, modifications can affect tire fitment on a 2016 Audi Trucks SQ5 even when the tire size looks correct on paper. Aftermarket wheels, different wheel widths, suspension changes, lowering, or body alterations can all change the clearance picture for either the 255/45R20 or 255/40R21 setup.
The safest approach is to verify the actual wheel diameter and width on the vehicle, then check steering, fender, and suspension clearance before changing tires. Even when overall tire dimensions are close, a different wheel package can shift how the tire sits in the wheel opening. That matters especially on performance-oriented vehicles that may have already been personalized by a previous owner.
What should I inspect before driving a 2016 Audi Trucks SQ5 on new tires?
Before driving a 2016 Audi Trucks SQ5 on new tires, inspect the wheels for the correct diameter and any visible damage, then confirm that the tire size matches the wheel setup. It also makes sense to look over valve stems, tread seating, and basic inflation so the vehicle starts out on the right footing.
A broader walk-around is worthwhile before road use. Check for rubbing at full steering lock, look at suspension and alignment wear patterns, and make sure there are no signs of air loss after installation. On a used SQ5, it is also smart to verify that all four tires match in size and general condition so the vehicle does not end up with a mixed setup.
What should I check before a longer drive in a 2016 Audi Trucks SQ5?
Before a longer drive, make sure the 2016 Audi Trucks SQ5 is on the correct tire size for its wheel diameter and inspect each tire for cuts, bulges, cracking, uneven wear, or slow air loss. Tire condition matters as much as size, especially on a vehicle that may alternate between regular use and longer parked periods.
It also helps to confirm inflation, inspect the spare or emergency equipment, and look for any signs of rubbing that may appear only when the vehicle is fully loaded or traveling at highway speed. A quick check of wheel hardware, alignment behavior, and suspension condition can prevent a small fitment issue from becoming much more noticeable on a longer trip.
