The 2014 Audi Trucks SQ5 blends compact luxury utility with the sharper character that made Audi’s S models appealing to drivers who wanted performance without giving up everyday usefulness. It sits in a modern era where wheel and tire choice has a strong effect on both stance and road feel. For this exact SQ5, the primary fitments are radial sizes 255/45R20 and 255/40R21, so the first decision is confirming which wheel diameter is on the vehicle. Within the 20-inch fitment, choices include different brands, tire series, and sidewall treatments. That makes this page most useful for owners balancing proper size, appearance, and the reality of any wheel or suspension changes already made.
Which Tire Size Is Right for The 2014 Audi Trucks SQ5
The 2014 Audi Trucks SQ5 uses two primary tire sizes, and the difference starts with wheel diameter: 255/45R20 fits a 20-inch rim, while 255/40R21 fits a 21-inch rim. Both are radial fitments, and both SQ5 sub-models can use either size, so the key step is confirming the actual wheel setup on the vehicle before comparing tire options.
A 255/40R21 tire uses a 255-millimeter section width, a 40-series aspect ratio, radial construction, and a 21-inch wheel. On the 2014 Audi Trucks SQ5, this size supports the larger-wheel fitment and keeps the buyer focused on proper wheel diameter first. The shorter sidewall profile is part of what distinguishes this size code from the 20-inch alternative, even though both belong to the same general modern performance-oriented sizing family. This is the size to evaluate when the SQ5 already wears 21-inch wheels and tire selection begins with matching that wheel diameter exactly.
A 255/45R20 tire uses a 255-millimeter section width, a 45-series aspect ratio, radial construction, and a 20-inch wheel. For the 2014 Audi Trucks SQ5, this size opens up the clearest product variety, including BFGoodrich, Nitto, and Pro-Trac choices, along with Blackwall, raised white letter, and Redline sidewall treatments. Available series include g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III. This is the size to compare when the vehicle has 20-inch wheels and appearance or product character matters as much as basic fitment.
Fitment is straightforward across the covered 2014 Audi Trucks SQ5 sub-models because both the Premium Plus and Prestige use the same two radial tire sizes. The practical difference is not trim level but whether the vehicle is sitting on 20-inch or 21-inch wheels.

2014 Audi Trucks SQ5 Premium Plus
The 2014 Audi Trucks SQ5 Premium Plus uses the same two radial fitments found across this model line, so tire choice starts with confirming wheel diameter rather than trim. Once the wheel size is verified, the decision shifts to available product style, sidewall presentation, and the kind of road use the vehicle sees.
The 2014 Audi Trucks SQ5 Prestige shares the same basic tire-fitment pattern as the Premium Plus, with both 20-inch and 21-inch radial sizes applying. That means trim alone does not settle the purchase decision, and the owner should confirm the installed wheels before selecting a tire.
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.

Tire Size & Fitment
What tire size fits a 2014 Audi Trucks SQ5?
The 2014 Audi Trucks SQ5 uses two primary tire sizes: 255/45R20 and 255/40R21. Both are radial sizes, and both apply across the SQ5 Premium Plus and Prestige sub-models, so the fitment question is tied more to wheel diameter than to trim name.
The practical step is checking which wheels are actually on the vehicle now. A 20-inch wheel requires the 255/45R20 size, while a 21-inch wheel requires 255/40R21, and owners should not choose by appearance alone. If the SQ5 has been modified with aftermarket wheels, verify diameter, width, and clearance before selecting a replacement tire.
What size rim does a 2014 Audi Trucks SQ5 use?
A 2014 Audi Trucks SQ5 uses either a 20-inch or 21-inch rim, depending on which of its two primary tire sizes is on the vehicle. The 255/45R20 fitment matches a 20-inch rim, and the 255/40R21 fitment matches a 21-inch rim.
That makes wheel confirmation the first step before ordering tires. Looking only at the model or sub-model is not enough, because both Premium Plus and Prestige can use either wheel diameter. Reading the tire sidewall, measuring the wheel, and checking for aftermarket wheel changes are all worthwhile before settling on a size.
Do all 2014 Audi Trucks SQ5 sub-models use the same tire size?
The 2014 Audi Trucks SQ5 Premium Plus and Prestige share the same overall fitment pattern, but that pattern includes two sizes rather than one. Both sub-models can use 255/45R20 or 255/40R21, and both sizes are radial constructions.
Because the sub-models overlap, the decisive detail is the actual wheel package on the vehicle in front of you. An owner should confirm whether the SQ5 has 20-inch or 21-inch rims before comparing products, since the trim badge alone does not narrow the choice to a single tire size.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2014 Audi Trucks SQ5?
Start with the basics: correct size, radial construction, and compatibility with the vehicle’s 20-inch wheels. In 255/45R20, the SQ5 has access to several different tire series and brands, including BFGoodrich, Nitto, and Pro-Trac, so the choice is not just about size but also about the character of the tire.
After confirming wheel diameter, compare sidewall style, rim-width suitability where stated, and any differences in weight or load information that matter to your use. A Blackwall tire gives a more understated look, while raised white letter or Redline options change the visual tone. Tire selection should also reflect whether the SQ5 remains stock or has wheel and suspension changes.
What sidewall styles are available for 2014 Audi Trucks SQ5 tires?
For the 2014 Audi Trucks SQ5 in 255/45R20, available sidewall styles include Blackwall, raised white letter, and Redline. Those choices create very different visual results even when the basic tire size remains the same, which matters for owners who want something subtler or something with more visual emphasis.
Sidewall treatment should be chosen after the fitment basics are settled, not before them. A Blackwall usually keeps the look clean and modern, while raised white letter and Redline options make the tire more noticeable. If appearance is part of the goal, confirm that the chosen sidewall style is being applied to the correct 20-inch SQ5 fitment.
What brands offer tires for the 2014 Audi Trucks SQ5?
In the available 255/45R20 fitment for the 2014 Audi Trucks SQ5, brands include BFGoodrich, Nitto, and Pro-Trac. Those options cover several tire series, including g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Street Pro III.
Brand choice is most useful when it helps narrow down the type of tire you want rather than turning into a popularity contest. Compare each option by size match, sidewall style, construction, and any stated rim-width or load details. The strongest buying decision usually comes from balancing appearance, intended driving use, and the wheel setup already on the SQ5.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Audi Trucks SQ5?
A period-style approach on a 2014 Audi Trucks SQ5 usually starts with keeping the correct modern radial size for the wheel currently on the vehicle, either 255/45R20 or 255/40R21. Since this is a modern performance SUV rather than a vintage restoration candidate, the visual decision is more about maintaining a clean era-appropriate look than recreating an older tire style.
For many owners, that means choosing a tire whose sidewall treatment matches the intended presentation of the vehicle. A Blackwall tire keeps the appearance restrained, while raised white letter or Redline options make a stronger statement. The best-looking result still depends on proper size, correct wheel diameter, and a stance that suits the SQ5’s current setup.
Which sidewall style suits a period-style 2014 Audi Trucks SQ5?
A Blackwall sidewall usually suits a period-style 2014 Audi Trucks SQ5 most naturally because it preserves the clean, understated look expected on a modern Audi performance utility vehicle. Raised white letter and Redline options are also available in 255/45R20, but they create a more customized visual effect.
The right choice depends on whether the goal is subtle factory-inspired presentation or a more individualized appearance. Owners trying to keep the SQ5 visually close to its original era often lean toward Blackwall, while custom-oriented builds may favor the more expressive options. Appearance decisions should come after confirming the correct wheel and tire size combination.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Audi Trucks SQ5?
Yes, modifications can affect tire fitment on a 2014 Audi Trucks SQ5 even when the tire size looks close to the original specification. Aftermarket wheels, changes in wheel width or offset, suspension lowering, and body alterations can all influence whether 255/45R20 or 255/40R21 remains the right practical choice.
That is why a modified SQ5 should be checked as an actual vehicle rather than treated like a stock example. Confirm wheel diameter first, then look at clearance through steering travel and suspension movement. Rubbing at the fender, inner liner, or suspension components can come from wheel setup changes just as easily as from tire size itself.
What should I inspect before driving a 2014 Audi Trucks SQ5 on new tires?
Before driving a 2014 Audi Trucks SQ5 on new tires, inspect the wheels for the correct diameter, verify that the tire size matches the installed rims, and check inflation pressure carefully. It also helps to look over the suspension and steering components so the new tires are not being asked to work around worn hardware.
A short, careful road test is worthwhile once the tires are mounted. Listen for rubbing, watch for vibration, and recheck pressure after the initial drive. Owners should also confirm that lug hardware is properly secured and that there is no contact at full lock, especially if the SQ5 has larger wheels or any suspension changes.
How often should tires on a 2014 Audi Trucks SQ5 be inspected?
Tires on a 2014 Audi Trucks SQ5 should be inspected regularly, not just when tread looks worn. Pressure, tread condition, sidewall damage, uneven wear, and signs of impact should all be checked routinely, especially on a vehicle that may see spirited road use or large-diameter wheel packages.
Monthly visual checks are a sensible habit, and any vibration, pull, or air loss deserves attention right away. The SQ5’s 20-inch and 21-inch fitments leave little reason to ignore small problems, because wear and ride issues can develop quickly when pressure is off or alignment is no longer correct. Frequent inspection helps protect both fitment and drivability.
