The 2015 Audi Trucks Q5 sits in the modern luxury crossover market with a blend of daily usability, all-weather confidence, and the more athletic road manners buyers expect from Audi. It is the kind of vehicle where wheel-and-tire choice noticeably affects both stance and driving character. For this Q5, primary fitment stays firmly in radial territory, with three metric radial sizes used across the model range: 235/60R18, 235/55R19, and 255/45R20. That means the real decision is less about vintage construction and more about confirming the exact sub-model and wheel diameter, then choosing the right combination of series and sidewall style for appearance and intended road use.
Which Tire Size Is Right for The 2015 Audi Trucks Q5
The 2015 Audi Trucks Q5 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three are radial metric sizes, but they are tied to different 18-inch, 19-inch, and 20-inch wheel setups. Before choosing a tire, confirm the specific Q5 trim and the actual wheels on the vehicle, especially if it has been changed from its original configuration.
Fit(s): Hybrid Prestige, Premium, Premium Plus 2.0, Premium Plus 3.0T, Prestige, TDI Premium Plus, and TDI Prestige
Construction: Radial|Rim: 19 in
235/55R19 is a metric radial size in which 235 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2015 Audi Trucks Q5, this size serves as a common fitment across several sub-models and suits a 19-inch wheel setup. It represents a mainstream modern sizing format that is familiar to current crossover owners. This is the size to evaluate when the vehicle is equipped with 19-inch wheels and you want to stay with the radial construction used on this Q5.
Fit(s): Hybrid Prestige, Premium Plus 3.0T, Prestige, TDI Premium Plus, and TDI Prestige
Construction: Radial|Rim: 20 in
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. On the 2015 Audi Trucks Q5, it belongs to specific upper-trim configurations that use 20-inch wheels rather than the smaller wheel packages. Available products in this size include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, raised white letter, and Redline sidewall treatments depending on the tire series. It is the size to confirm when your Q5 has the larger 20-inch wheel package and appearance choice matters alongside fitment.
235/60R18 is a metric radial size where 235 denotes nominal section width in millimeters, 60 is the aspect ratio, R marks radial construction, and 18 indicates wheel diameter in inches. On the 2015 Audi Trucks Q5, this size is used on certain sub-models equipped with 18-inch wheels instead of the 19-inch or 20-inch alternatives. Its code follows the same modern metric system as the other Q5 fitments, but the wheel diameter makes it a separate fitment decision. Choose this size only after confirming that the vehicle is actually running the 18-inch wheel setup.
Tire fitment on the 2015 Audi Trucks Q5 is not completely uniform across the range, because different sub-models use different wheel-and-tire combinations. Checking the exact trim matters first, and confirming the wheel diameter on the vehicle matters just as much before selecting a replacement tire.

2015 Audi Trucks Q5 Hybrid Prestige
The 2015 Audi Trucks Q5 Hybrid Prestige uses either a 235/55R19 or 255/45R20 radial fitment depending on the wheel package on the vehicle. Tire selection starts with confirming whether it has 19-inch or 20-inch wheels, then comparing available product styles within the correct size.
The 2015 Audi Trucks Q5 Premium uses 235/60R18 or 235/55R19 radial tires, so this trim can appear with either 18-inch or 19-inch wheels. That makes wheel confirmation the first step, followed by choosing a tire that matches the vehicle’s current setup and intended road use.
The 2015 Audi Trucks Q5 Premium Plus 2.0 uses either 235/60R18 or 235/55R19 in radial construction. The practical decision is confirming which wheel diameter is on the vehicle now, especially if the Q5 has changed hands or has been updated with a different wheel package.
The 2015 Audi Trucks Q5 Premium Plus 3.0T uses 235/55R19 or 255/45R20 radial tires rather than the 18-inch setup found elsewhere in the range. That means selection comes down to verifying whether the vehicle is on 19-inch or 20-inch wheels and then choosing within the correct size.
The 2015 Audi Trucks Q5 Prestige uses either 235/55R19 or 255/45R20 radial tires. Buyers should verify the actual wheel package on the vehicle first, since the 19-inch and 20-inch fitments are both valid for this trim but are not interchangeable without matching the wheel diameter.
The 2015 Audi Trucks Q5 TDI Premium Plus uses 235/55R19 or 255/45R20 in radial construction. The key step is identifying the wheel diameter already on the vehicle so the replacement tire matches the existing setup rather than another valid Q5 configuration.
The 2015 Audi Trucks Q5 TDI Prestige uses either 235/55R19 or 255/45R20 radial tires. Because both sizes belong to this sub-model, the right replacement depends on checking the actual wheel package and then narrowing the choice by series and sidewall preference where applicable.
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.
Best 2015 Audi Trucks Q5 Tires for Sale
Available product choice centers on 255/45R20, with radial options from BFGoodrich, Nitto, and Pro-Trac. The product grid is where to compare series differences, Blackwall versus raised white letter or Redline sidewalls, and rim-width details tied to the larger 20-inch Q5 wheel setup.
Owners of a 2015 Audi Trucks Q5 usually need to sort out trim-level tire size, wheel diameter, and the difference between the 18-inch, 19-inch, and 20-inch fitments. The questions below focus on size selection, product choice, appearance, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2015 Audi Trucks Q5?
A 2015 Audi Trucks Q5 uses one of three radial tire sizes: 235/60R18, 235/55R19, or 255/45R20. The correct size depends on the exact sub-model and, just as importantly, the wheel package currently on the vehicle.
The easiest mistake is choosing a size that fits a different Q5 trim but not the wheels on your own vehicle. Check the sub-model, then confirm whether the vehicle has 18-inch, 19-inch, or 20-inch wheels before comparing tire options, because the size must match the installed rim diameter.
What size rim does a 2015 Audi Trucks Q5 use?
The 2015 Audi Trucks Q5 uses 18-inch, 19-inch, or 20-inch rims depending on the sub-model and wheel setup. Those rim diameters correspond to the three tire sizes used on this Q5: 235/60R18, 235/55R19, and 255/45R20.
Rim diameter is the first fitment check because the tire must match the wheel exactly. A Q5 that is valid with 19-inch tires in one configuration may also be valid with 20-inch tires in another, so it is important to inspect the actual wheels on the vehicle rather than relying on trim name alone.
Why does the 2015 Audi Trucks Q5 have more than one tire size?
The 2015 Audi Trucks Q5 has more than one tire size because different sub-models were fitted with different wheel packages. Across the range, the Q5 appears with 18-inch, 19-inch, and 20-inch rim diameters, each requiring its own matching tire size.
That variation means there is no single universal tire size for every 2015 Q5. Premium and Premium Plus 2.0 models can use 18-inch or 19-inch setups, while several Prestige, TDI, and 3.0T configurations use 19-inch or 20-inch combinations, so wheel confirmation is always part of correct tire selection.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2015 Audi Trucks Q5?
Start with the basics: the vehicle must actually use the 255/45R20 fitment and have 20-inch wheels. From there, compare radial tire series, sidewall style, and any rim-width guidance that applies to the product, since those details affect how the tire suits the Q5’s appearance and intended use.
Available 255/45R20 choices include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, raised white letter, and Redline sidewall treatments in the mix. The right choice depends on whether you want a more understated modern look or a more expressive presentation, while still staying within the correct size for the wheel.
What sidewall styles are available for 2015 Audi Trucks Q5 tires?
Within the 255/45R20 fitment for the 2015 Audi Trucks Q5, available sidewall styles include Blackwall, raised white letter, and Redline. Those choices all stay within radial construction, but they give the vehicle a noticeably different visual character.
Blackwall keeps the presentation cleaner and more understated, while raised white letter and Redline add a stronger performance-oriented accent. Sidewall style should be chosen only after confirming the correct tire size and wheel diameter, since appearance options matter only when they are attached to the right fitment.
What brands offer tires for the 2015 Audi Trucks Q5?
The 255/45R20 tire size for the 2015 Audi Trucks Q5 is available from BFGoodrich, Nitto, and Pro-Trac. Those brands appear across several radial tire series, giving buyers different approaches to style and product character within the same basic size.
Brand should be one part of the decision, not the whole decision. It makes more sense to compare the correct size first, then look at series, sidewall treatment, and wheel-compatibility details so the tire choice matches the Q5’s actual wheel setup and the kind of appearance you want.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Audi Trucks Q5?
A period-style approach on a 2015 Audi Trucks Q5 begins with staying in the correct original-type radial size for the sub-model and wheel package already on the vehicle. For a newer luxury crossover like this, the right visual starting point is usually more about preserving the proper wheel-and-tire proportion than recreating a vintage construction style.
Once size is settled, appearance comes from the product’s sidewall treatment and overall presentation. A Blackwall tire keeps the look closest to a restrained modern factory-era aesthetic, while options like Redline or raised white letter create a more customized impression that may suit an owner’s taste but changes the visual tone.
Which sidewall style suits a period-style 2015 Audi Trucks Q5?
For a period-style 2015 Audi Trucks Q5, Blackwall is usually the most restrained and era-appropriate visual direction among the available 255/45R20 options. It preserves a clean modern crossover appearance without drawing attention away from the vehicle’s wheel design and overall proportions.
Raised white letter and Redline sidewalls create a stronger custom or enthusiast-oriented statement. Those styles can be appealing, but they shift the Q5 away from a subtle original-era presentation, so they are best chosen when personal style matters more than maintaining a straightforward factory-era look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Audi Trucks Q5?
Yes. Modifications such as aftermarket wheels, suspension changes, lowering, or body alterations can affect tire fitment on a 2015 Audi Trucks Q5 even when the tire size is correct for a stock configuration. Wheel diameter, wheel width, and available clearance all matter once the vehicle has been changed.
A Q5 that originally used 235/55R19, 255/45R20, or 235/60R18 may no longer have its original setup. Inspect the actual wheel size, check for rubbing at full steering lock and through suspension travel, and confirm that the tire suits the current vehicle configuration rather than the trim name alone.
What should I inspect before driving a 2015 Audi Trucks Q5 on new tires?
Before driving a 2015 Audi Trucks Q5 on new tires, confirm that all four tires match the intended size and wheel diameter for the vehicle’s setup. It is also worth checking inflation, bead seating, valve condition, and any obvious clearance issues around fenders, suspension components, and steering travel.
A short inspection drive should follow, with attention to vibration, pulling, or contact noises that could point to fitment or installation problems. Since this Q5 can use several wheel-and-tire combinations, it is smart to verify the finished setup carefully rather than assuming any Q5 size belongs on every sub-model.
How often should tires on a 2015 Audi Trucks Q5 be inspected?
Tires on a 2015 Audi Trucks Q5 should be inspected regularly, not just at replacement time. Check them for uneven wear, cuts, bulges, cracking, embedded debris, and air loss, and pay extra attention if the vehicle is driven infrequently or sits for long periods between uses.
A routine visual check before longer trips is a good habit, especially on a crossover that may alternate between local driving and highway use. Consistent pressure checks and early attention to wear patterns can also reveal wheel, alignment, or suspension issues before they turn into larger fitment or handling problems.
