2020 Audi Trucks Q5 PHEV Tires

The 2020 Audi Trucks Q5 PHEV uses two primary tire sizes: 235/55R19 and 255/45R20. Both are radial sizes, and the correct one depends on the trim and wheel package. Premium uses 235/55R19, while Premium Plus and Prestige can be equipped with either 235/55R19 or 255/45R20.

That means tire selection starts with the actual wheels on the vehicle, not just the model name on the tailgate. A Q5 PHEV with 19-inch wheels needs the 19-inch size, and one with 20-inch wheels needs the 20-inch size. If the vehicle has changed hands or has aftermarket wheels, confirm the mounted wheel diameter before buying tires.

The 2020 Audi Trucks Q5 PHEV uses either a 19-inch or 20-inch rim, depending on the tire size and trim configuration. The 235/55R19 fitment matches a 19-inch rim, and the 255/45R20 fitment matches a 20-inch rim. Both are modern radial applications rather than older bias-ply sizing formats.

Rim diameter is the first fitment detail to verify because a 19-inch tire cannot be mounted on a 20-inch wheel, and the reverse is equally true. Premium Plus and Prestige can appear with either setup, so an owner should inspect the wheels directly. Wheel width also matters once the tire size is known, especially when comparing available 20-inch products.

No, not all 2020 Audi Trucks Q5 PHEV sub-models use the same tire size. Premium uses 235/55R19, while Premium Plus and Prestige can use either 235/55R19 or 255/45R20. The difference is tied to wheel package, so the exact trim alone does not always settle the question on the upper models.

This matters because a buyer cannot assume every Premium Plus or Prestige wears the same wheel and tire setup. The practical approach is to confirm both the sub-model and the wheels currently on the vehicle. That prevents ordering a 20-inch tire for a Q5 PHEV still running the 19-inch package or choosing a tire style that only exists in one size.

Start with the correct size for the vehicle's wheel package: 235/55R19 or 255/45R20. From there, compare tire construction, wheel compatibility, sidewall style, brand, and tire series where choices exist. The 20-inch size has the broader visible product spread, so that fitment invites a closer look at how the tire will suit the vehicle's intended use and presentation.

A careful choice goes beyond matching the size stamped on the sidewall. Check the wheel diameter, confirm the wheel width falls within the tire's approved range when that specification is available, and think about whether appearance matters as much as everyday driving character. That approach helps narrow the right tire without treating every same-size option as identical.

In the available 255/45R20 fitment for the 2020 Audi Trucks Q5 PHEV, sidewall styles include blackwall, RWL, and redline. Blackwall appears across several brands and series, while Pro-Trac Street Pro III is also offered in raised white letter and redline form. Those choices create a noticeable difference in how the 20-inch package presents on the vehicle.

Sidewall style should be chosen only after confirming the correct tire size and wheel diameter. A blackwall usually keeps the look understated and modern, while RWL and redline add more visual presence. Owners trying to shape the vehicle's appearance should compare sidewall treatment alongside tire series and wheel setup, not as a separate decision from fitment.

For the 255/45R20 fitment used on some 2020 Audi Trucks Q5 PHEV configurations, available brands include BFGoodrich, Nitto, and Pro-Trac. Those products span several radial series, including g-Force Comp 2 AS, g-Force Sport Comp 2, Nitto NT555 G2, and Pro-Trac Street Pro III. The brand choice is really part of a broader comparison that also includes sidewall treatment and wheel compatibility.

Rather than choosing by brand name alone, compare the exact tire series, size notation, and approved rim-width range where it is stated. Some owners may prefer a conventional blackwall look, while others may want the visual character of raised white letters or a redline. Matching the right brand and series to the actual wheel setup keeps the decision practical.

A 2020 Audi Trucks Q5 PHEV is a modern vehicle, so the starting point is still the correct contemporary radial size for the wheel package rather than a vintage-style construction. If the vehicle uses 255/45R20, available choices include blackwall, raised white letter, and redline sidewall treatments that can shift the overall look more noticeably than the size itself.

For a cleaner, more restrained presentation, many buyers focus on blackwall options. An owner who wants a stronger visual statement may lean toward RWL or redline, but the tire still needs to match the exact wheel diameter and intended trim setup. Appearance should follow fitment, not replace it, especially on a vehicle that may already have wheel-package variation.

On a 2020 Audi Trucks Q5 PHEV, construction is less of an appearance divide than it would be on an older collector vehicle because the primary fitments are already modern radials. The more visible appearance changes come from sidewall style and tire series, especially in the 255/45R20 fitment where blackwall, RWL, and redline options are available.

That shifts the buyer's attention toward presentation within the correct modern size rather than choosing between bias-ply and radial looks. A restoration-minded owner should first keep the wheel diameter and size consistent with the vehicle's actual setup, then compare sidewall treatment against the desired visual character. The tire can influence the stance and finish without changing the essential fitment.

Yes, modifications can affect tire fitment on a 2020 Audi Trucks Q5 PHEV even when the tire size itself appears correct. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, or body alterations can all change clearance at the fender, strut, or steering range. That matters most on a vehicle that already has more than one factory wheel diameter in circulation.

An owner should confirm the actual wheel diameter and width on the vehicle before selecting tires, especially on Premium Plus and Prestige trims. It also helps to check turning clearance and suspension travel if the vehicle has been altered from stock. A tire that matches the nominal size still needs to suit the real-world wheel and chassis setup on the vehicle.

Before driving a 2020 Audi Trucks Q5 PHEV on new tires, inspect basic mounting and condition points such as correct size, air pressure, bead seating, valve condition, and visible sidewall or tread damage. It is also wise to look for signs of rubbing at full steering lock and to confirm that all four tires match the intended wheel setup on the vehicle.

A short road check can reveal vibration, pull, or unexpected clearance problems before the vehicle is used normally. Since this Q5 PHEV can wear either 19-inch or 20-inch fitment depending on trim and wheels, that confirmation matters more than it would on a one-size application. Any uncertainty about wheel compatibility or installation should be addressed by a qualified tire professional.

Tires on a 2020 Audi Trucks Q5 PHEV should be inspected regularly rather than only when a problem appears. Look over tread condition, sidewall cracking, cuts, bulges, and any sign of air loss, and check pressure on a routine schedule. A modern plug-in hybrid crossover still benefits from simple, frequent checks that catch issues before they become drivability concerns.

Inspection becomes even more important if the vehicle is driven infrequently, stored for periods, or fitted with non-original wheels. Low-use vehicles can develop age-related issues even when tread depth still looks acceptable. A quick visual check before longer trips, along with pressure monitoring and occasional clearance review, helps keep the correct 19-inch or 20-inch setup road-ready.
