The 2017 Volkswagen Trucks Touareg sits in the modern luxury-SUV space with a mix of highway composure, substantial curb presence, and trim-specific wheel packages that can change the tire decision dramatically. For owners, this is less about choosing among vintage-style constructions and more about matching the exact setup already on the vehicle. The 2017 Volkswagen Trucks Touareg uses three different primary radial tire sizes depending on sub-model: 255/55R18, 275/45R20, or 275/40R21. That makes wheel diameter and trim identification the first step, followed by evaluating the tire's profile and intended road use. Getting that foundation right helps preserve ride quality, appearance, and proper fitment.
Which Tire Size Is Right for The 2017 Volkswagen Trucks Touareg
Three different tire sizes apply to the 2017 Volkswagen Trucks Touareg, and each one is tied to a specific sub-model and wheel diameter. The first thing to confirm is the exact trim and whether the vehicle still wears its original 18-inch, 20-inch, or 21-inch wheels. Once that is established, the real choice becomes selecting the right radial tire within the correct size and profile for the way the Touareg is driven and maintained.
A 275/40R21 tire uses a 275-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 21-inch rim diameter. On the 2017 Volkswagen Trucks Touareg, this size belongs to a trim-specific wheel package and delivers a lower-profile modern SUV fitment than the smaller-diameter alternatives. The shorter sidewall gives this size a distinctly different look from the 18-inch setup, even though both are radial designs. Choosing 275/40R21 starts with confirming that the vehicle has the correct 21-inch wheels and enough clearance for the exact tire selected.
A 255/55R18 tire combines a 255-millimeter nominal section width with a 55-series profile, radial construction, and an 18-inch rim diameter. For the 2017 Volkswagen Trucks Touareg, this size represents the smallest wheel diameter used across the covered sub-models, with a taller sidewall than the 20-inch and 21-inch fitments. That profile affects both the vehicle's visual stance and the tire-selection process, since 18-inch wheel fitment is not interchangeable with the larger-diameter setups. This is the right size to evaluate only after confirming the Touareg's exact sub-model and wheel package.
A 275/45R20 tire pairs a 275-millimeter nominal section width with a 45-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2017 Volkswagen Trucks Touareg, this size sits between the 18-inch and 21-inch fitments in wheel diameter while sharing the same nominal width as the 21-inch option. That makes it important to distinguish by rim diameter rather than width alone. Selecting 275/45R20 means confirming the vehicle's 20-inch wheel setup first, then comparing tires within that size for the right balance of appearance, use, and compatibility.
Tire fitment for the 2017 Volkswagen Trucks Touareg varies by sub-model, and each trim uses its own radial size and wheel diameter. Checking the exact trim matters before comparing tires, because the 18-inch, 20-inch, and 21-inch setups are distinct fitments rather than interchangeable versions of the same package.

2017 Volkswagen Trucks Touareg V6 Executive
The 2017 Volkswagen Trucks Touareg V6 Executive uses the largest wheel fitment among these sub-models, with a 275/40R21 radial tire. Tire selection starts with confirming that the vehicle still has its 21-inch wheels, then comparing options in that exact size for profile, road use, and overall fitment.
The 2017 Volkswagen Trucks Touareg V6 Sport uses a 255/55R18 radial tire on an 18-inch wheel. That gives this trim a different tire profile from the larger-wheel Touareg versions, so selection should stay focused on the 18-inch setup rather than assuming another Touareg size will cross over.
The 2017 Volkswagen Trucks Touareg V6 Wolfsburg uses a 275/45R20 radial tire on a 20-inch wheel. For this sub-model, the key step is verifying the 20-inch wheel package and then evaluating tires within that exact size for proper profile, clearance, and intended driving use.
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.
Frequently Asked Questions
The most important tire questions for the 2017 Volkswagen Trucks Touareg center on trim-specific sizing, wheel diameter, radial fitment, and what to inspect before replacing tires on a modern luxury SUV with multiple factory wheel packages.
Tire Size & Fitment
What tire size fits a 2017 Volkswagen Trucks Touareg?
The 2017 Volkswagen Trucks Touareg uses one of three radial tire sizes, depending on sub-model: 255/55R18, 275/45R20, or 275/40R21. These are not universal across the model line. The V6 Sport uses 255/55R18, the V6 Wolfsburg uses 275/45R20, and the V6 Executive uses 275/40R21.
The practical takeaway is that trim identification comes before tire shopping. Two Touareg tires may have similar overall diameter, but they are built for different wheel diameters, and the wheel itself determines what can be mounted. Checking the sub-model, wheel size, and the current sidewall marking helps prevent choosing an 18-inch, 20-inch, or 21-inch tire for the wrong vehicle setup.
What size rim does a 2017 Volkswagen Trucks Touareg use?
A 2017 Volkswagen Trucks Touareg can use an 18-inch, 20-inch, or 21-inch rim, depending on sub-model. The V6 Sport uses an 18-inch rim with 255/55R18 tires, the V6 Wolfsburg uses a 20-inch rim with 275/45R20 tires, and the V6 Executive uses a 21-inch rim with 275/40R21 tires.
Rim diameter is the first fitment check because a tire must match the wheel it mounts to. Even when two Touareg tire sizes have a similar outside diameter, an 18-inch tire cannot be mounted on a 20-inch or 21-inch wheel. It is also worth confirming that the vehicle has not been changed to an aftermarket wheel package before selecting a replacement tire.
Why does the 2017 Volkswagen Trucks Touareg have more than one tire size?
The 2017 Volkswagen Trucks Touareg has more than one tire size because the covered sub-models use different wheel packages. The V6 Sport, V6 Wolfsburg, and V6 Executive each pair with a different radial tire size and rim diameter. That is why the Touareg appears with 18-inch, 20-inch, or 21-inch tire fitments within the same model year.
This matters because tire selection is tied to the exact wheel setup, not just the model name on the liftgate. A Touareg owner should confirm the trim level, verify the wheel diameter already on the vehicle, and check the sidewall of the current tires before ordering replacements. That extra step helps avoid mixing sizes that belong to another Touareg sub-model.
Choosing the Right Tire
What should I consider when choosing a 2017 Volkswagen Trucks Touareg tire?
Start with the exact tire size that matches the Touareg's sub-model and wheel diameter: 255/55R18, 275/45R20, or 275/40R21. Because all three primary fitments are radial, the main decision is not bias-ply versus radial construction but choosing the correct modern size for the vehicle's existing wheel package.
After size is confirmed, compare tires with the vehicle's real use in mind. A daily-driven Touareg, a highway-oriented SUV, and a lightly used secondary vehicle may lead to different priorities in ride, tread design, or overall character. It also helps to confirm the actual wheel setup if the vehicle has been changed from its original trim-specific package.
How do I choose between the available 2017 Volkswagen Trucks Touareg tire sizes?
You do not choose among the three sizes based on preference alone, because each one belongs to a specific Touareg sub-model and wheel diameter. The right size is determined first by whether the vehicle is a V6 Sport, V6 Wolfsburg, or V6 Executive, and second by whether it still carries the corresponding 18-inch, 20-inch, or 21-inch wheels.
Once the correct size is established, then it makes sense to compare tires within that size. That approach keeps the focus on proper mounting and vehicle compatibility rather than trying to substitute across trim packages. Checking the sidewall on the current tires and measuring the wheel diameter is a smart safeguard, especially if the SUV was purchased used.
How important is wheel diameter when choosing tires for a 2017 Volkswagen Trucks Touareg?
Wheel diameter is critical on the 2017 Volkswagen Trucks Touareg because the three primary sizes mount to three different rims: 18, 20, and 21 inches. A 255/55R18 is built for an 18-inch wheel, a 275/45R20 for a 20-inch wheel, and a 275/40R21 for a 21-inch wheel.
This is the fitment point that eliminates the most mistakes. Width and aspect ratio may change the look and profile of the tire, but the bead must still match the wheel diameter exactly. On a used Touareg, wheel swaps are always possible, so it is worth physically confirming the installed wheel size instead of relying only on trim-name assumptions.
Restoration & Appearance
Does correct tire fitment matter for the appearance of a 2017 Volkswagen Trucks Touareg?
Yes, correct tire fitment has a noticeable effect on the appearance of a 2017 Volkswagen Trucks Touareg. The V6 Sport's 255/55R18, the V6 Wolfsburg's 275/45R20, and the V6 Executive's 275/40R21 each create a different visual balance because the wheel diameter and sidewall profile change from one sub-model to another.
Using the right size helps preserve the intended stance and proportion for that specific trim. A lower-profile 21-inch setup presents differently than an 18-inch package with a taller sidewall, even when overall tire diameter stays in a similar range. Owners who care about appearance should match the tire to the actual wheel package rather than selecting by width alone.
Should a period-style or original-looking approach matter on a 2017 Volkswagen Trucks Touareg?
On a 2017 Volkswagen Trucks Touareg, appearance usually centers more on preserving the correct trim-specific wheel-and-tire package than on vintage restoration concerns. This is a modern SUV with modern radial fitments, so the visual goal is generally to maintain the proper 18-inch, 20-inch, or 21-inch presentation that belongs to the vehicle's sub-model.
That makes exact size selection more important than chasing a historical sidewall style. Keeping the V6 Sport, V6 Wolfsburg, or V6 Executive on its proper tire size helps the Touareg retain the look intended for that wheel package. If originality matters on a particularly well-kept example, confirming the current setup against model-specific vehicle documentation is worthwhile.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Volkswagen Trucks Touareg?
Yes, modifications can affect tire fitment on a 2017 Volkswagen Trucks Touareg. Aftermarket wheels, suspension changes, lowering, or non-original wheel offsets can alter the clearance available for 255/55R18, 275/45R20, or 275/40R21 tires. Even if the tire size matches a Touareg trim, the actual vehicle setup may no longer match the original wheel package.
That is why it helps to verify wheel diameter, wheel width, and clearance at full steering lock before assuming a replacement tire will behave like the previous one. A used Touareg may already have modifications that are not obvious at first glance. Inspecting the wheel and suspension setup first reduces the chance of rubbing or other fitment issues.
What should I inspect before driving a 2017 Volkswagen Trucks Touareg on new tires?
Before driving a 2017 Volkswagen Trucks Touareg on new tires, inspect the installed wheel size, confirm the tire size matches the sub-model, and check inflation pressure carefully. It is also smart to look over the wheels for damage and make sure the tires seat properly and clear the suspension, fenders, and inner liners.
A short road test should follow, with attention to steering feel, vibration, and any sign of rubbing during turns or over bumps. Modern SUVs like the Touareg can hide fitment issues until the suspension is loaded or the steering is near full lock. Rechecking pressure after installation and inspecting for uneven contact helps catch small problems early.
How often should tires on a 2017 Volkswagen Trucks Touareg be inspected?
Tires on a 2017 Volkswagen Trucks Touareg should be inspected regularly, not just when tread looks worn. A routine check should include inflation pressure, tread condition, cuts, bulges, irregular wear, and any sign of air loss. Because this Touareg uses trim-specific sizing, it is also worth confirming that all four tires match the intended wheel-and-tire setup.
Monthly checks are a sensible habit, with extra attention before highway trips or seasonal use changes. Owners should also inspect the inner sidewall and shoulder areas, since those can be easy to miss on wider modern SUV tires. Catching pressure loss or uneven wear early can prevent larger handling, ride, or fitment problems from developing.
