The 2018 Volkswagen Trucks Tiguan arrived as a modern compact crossover aimed at buyers who wanted everyday utility without giving up a more composed, car-like road feel. Its trim walk spans practical daily-driver models through sharper R-Line versions, and that matters because tire fitment changes across the lineup. This Tiguan uses five primary radial sizes, from 215/65R17 on S and SE models up to 255/40R20 on SEL Premium R-Line versions. That means the real choice starts with identifying the exact sub-model and wheel diameter, then narrowing the decision to the correct size, overall tire character, and appearance. On vehicles that may already have wheel upgrades, confirming the actual setup before replacement is especially important.
Which Tire Size Is Right for The 2018 Volkswagen Trucks Tiguan
Five primary tire sizes apply to the 2018 Volkswagen Trucks Tiguan, and they vary by sub-model rather than by alternate construction type. Every fitment is a radial, but the vehicle uses 17-inch, 18-inch, 19-inch, and 20-inch wheel diameters depending on trim. The first step is confirming the exact sub-model and wheel size on the vehicle, especially since two different tire sizes use 19-inch rims.
215/65R17 is a modern metric radial size: 215 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2018 Volkswagen Trucks Tiguan, this size serves the S, S 4Motion, SE, and SE 4Motion models, making it the core fitment for the more mainstream trims. Its role is straightforward and practical, so the main concerns are matching the actual 17-inch wheel setup and choosing a tire that suits the vehicle's intended street use. It is the correct starting point for replacement on those trims rather than a substitute for larger-wheel versions.
235/55R18 follows the same modern metric radial format, with a 235-millimeter section width, a 55-series profile, radial construction, and an 18-inch rim diameter. This size applies to the 2018 Volkswagen Trucks Tiguan SEL and SEL 4Motion, placing it between the smaller 17-inch fitment and the larger 19- and 20-inch R-Line-oriented setups. It keeps the buyer focused on confirming that the vehicle is actually on its original 18-inch wheels before comparing tire options. For SEL models, this is the size to evaluate when maintaining the intended wheel and tire balance for that trim level.
235/50R19 uses a 235-millimeter nominal width, a 50-series aspect ratio, radial construction, and a 19-inch rim. On the 2018 Volkswagen Trucks Tiguan, this size belongs to the SEL Premium and SEL Premium 4Motion, so it should not be confused with the wider 255/45R19 fitment used on other 19-inch-wheel trims. The practical issue here is that wheel diameter alone is not enough to identify the right tire, since two different 19-inch sizes exist. Buyers replacing tires on a SEL Premium model should verify both the sub-model and the size on the vehicle before moving forward.
Fit(s): SEL Premium R-Line and SEL Premium R-Line 4Motion
Construction: Radial|Rim: 20 in
255/40R20 is a modern metric radial size with a 255-millimeter nominal width, a 40-series profile, and a 20-inch rim diameter. This fitment is used on the 2018 Volkswagen Trucks Tiguan SEL Premium R-Line and SEL Premium R-Line 4Motion, where the tire selection leans toward the largest wheel package in the range. Available product choice shown here includes a BFGoodrich g-Force Phenom T/A in Blackwall form, giving this size a distinctly performance-oriented product character. It is the correct size to evaluate for those R-Line Premium models, but wheel width and actual vehicle setup should still be checked before replacement.
255/45R19 combines a 255-millimeter nominal section width with a 45-series profile, radial construction, and a 19-inch wheel diameter. On the 2018 Volkswagen Trucks Tiguan, this size applies to the SEL R-Line and SEL R-Line 4Motion, making it separate from the narrower 235/50R19 fitment used on SEL Premium versions even though both share a 19-inch rim diameter. That distinction matters because a 19-inch wheel alone does not confirm the correct replacement size. For an SEL R-Line, this is the fitment to match when keeping the original trim-specific wheel and tire package intact.
Tire fitment on the 2018 Volkswagen Trucks Tiguan changes with the sub-model, and that makes trim identification essential before choosing a replacement tire. Several versions share the same size, but the lineup spans four wheel diameters and two different 19-inch fitments, so the exact model designation matters.

2018 Volkswagen Trucks Tiguan S
The 2018 Volkswagen Trucks Tiguan S uses the 215/65R17 radial size on a 17-inch wheel package. Tire selection for this sub-model is mainly about staying with the correct metric radial fitment and confirming that the vehicle has not been changed to a different wheel setup.
The 2018 Volkswagen Trucks Tiguan S 4Motion uses the same 215/65R17 radial fitment as the front-drive S model. That keeps replacement straightforward, though it is still wise to verify the actual wheel size on the vehicle before ordering if aftermarket wheels have ever been installed.
The 2018 Volkswagen Trucks Tiguan SE also uses 215/65R17 radial tires, sharing the same basic fitment as the S trims. The buying decision centers less on alternate size choices and more on selecting the right tire within that fitment for the vehicle's road use and current wheel setup.
The 2018 Volkswagen Trucks Tiguan SE 4Motion stays with the 215/65R17 radial size. That makes fitment relatively simple, but replacement should still begin with confirming the vehicle remains on its original 17-inch wheels rather than a later trim's larger package.
The 2018 Volkswagen Trucks Tiguan SEL uses a 235/55R18 radial tire, moving to an 18-inch wheel package. For this sub-model, the main task is matching that trim-specific size rather than assuming that any larger Tiguan wheel and tire combination will serve the same role.
The 2018 Volkswagen Trucks Tiguan SEL 4Motion uses the same 235/55R18 radial fitment as the SEL. Tire replacement should focus on preserving the correct 18-inch setup and checking the actual wheels on the vehicle if there is any chance of prior modifications.
The 2018 Volkswagen Trucks Tiguan SEL Premium uses 235/50R19 radial tires. Since the Tiguan range also includes a different 19-inch fitment, this sub-model calls for extra care in confirming the exact size before comparing replacement options.
The 2018 Volkswagen Trucks Tiguan SEL Premium 4Motion uses the 235/50R19 radial size. That means the buyer should verify both the sub-model and the sidewall marking on the current tire, because another 19-inch Tiguan fitment in this model year uses a different width and profile.
The 2018 Volkswagen Trucks Tiguan SEL Premium R-Line uses the largest primary fitment in the range, 255/40R20. Tire selection here starts with confirming the 20-inch wheel package and then comparing products that suit this larger, lower-profile radial size.
2018 Volkswagen Trucks Tiguan SEL Premium R-Line 4Motion
The 2018 Volkswagen Trucks Tiguan SEL Premium R-Line 4Motion also uses 255/40R20 radial tires. Because this fitment sits at the largest end of the Tiguan lineup, wheel width and the actual installed wheel package are worth checking before choosing a replacement.
The 2018 Volkswagen Trucks Tiguan SEL R-Line uses 255/45R19 radial tires rather than the narrower 235/50R19 found on SEL Premium models. That makes sub-model confirmation especially important on 19-inch-wheel Tiguans, since the correct replacement depends on the exact trim.
The 2018 Volkswagen Trucks Tiguan SEL R-Line 4Motion uses the 255/45R19 radial fitment. Buyers should treat this as its own trim-specific size and verify the sidewall marking before replacement, especially on vehicles that may have swapped wheels within the Tiguan range.
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 2018 Volkswagen Trucks Tiguan Tires for Sale
Available product choice is currently concentrated in 255/40R20, where the 2018 Volkswagen Trucks Tiguan can be matched with a BFGoodrich g-Force Phenom T/A Blackwall radial. For SEL Premium R-Line models, that makes series character, sidewall appearance, and wheel-width compatibility the key comparison points.
These FAQs focus on the exact tire sizes used across the 2018 Volkswagen Trucks Tiguan lineup, how trim level affects fitment, and what to check when comparing radial tires, wheel sizes, and real-world vehicle setup.
Tire Size & Fitment
What tire size fits a 2018 Volkswagen Trucks Tiguan?
The 2018 Volkswagen Trucks Tiguan uses five primary tire sizes: 215/65R17, 235/55R18, 235/50R19, 255/45R19, and 255/40R20. The correct size depends on the exact sub-model, with S and SE trims using 215/65R17, SEL using 235/55R18, SEL Premium using 235/50R19, SEL R-Line using 255/45R19, and SEL Premium R-Line using 255/40R20.
The practical takeaway is that trim identification matters as much as the model name. Two different 19-inch sizes appear in the lineup, so wheel diameter alone is not enough to confirm replacement. Checking the current sidewall marking, the wheel size, and the exact trim helps avoid choosing a tire that belongs to a different Tiguan configuration.
What size rim does a 2018 Volkswagen Trucks Tiguan use?
A 2018 Volkswagen Trucks Tiguan may use 17-inch, 18-inch, 19-inch, or 20-inch rims, depending on sub-model. The 215/65R17 fitment uses a 17-inch rim, 235/55R18 uses an 18-inch rim, 235/50R19 and 255/45R19 both use 19-inch rims, and 255/40R20 uses a 20-inch rim.
That spread makes wheel confirmation a necessary first step before buying tires. Since two fitments share a 19-inch diameter, measuring only the wheel or reading only the rim size does not fully identify the correct replacement. The safest approach is to confirm the trim level and read the full size molded into the existing tire sidewall.
Why does the 2018 Volkswagen Trucks Tiguan have more than one tire size?
The 2018 Volkswagen Trucks Tiguan has more than one tire size because different sub-models use different wheel-and-tire packages. Mainstream trims use smaller fitments such as 215/65R17, while SEL, SEL Premium, SEL R-Line, and SEL Premium R-Line models move to larger diameters and, in some cases, wider tires.
That means tire selection is tied to trim and wheel package rather than to the model name alone. It also means a replacement should match the vehicle's actual setup, not simply another Tiguan size from the same year. Any vehicle with wheel upgrades or take-off wheels from another trim deserves an extra fitment check before ordering.
Choosing the Right Tire
What should I consider when choosing a 255/40R20 tire for a 2018 Volkswagen Trucks Tiguan?
Start by confirming that the Tiguan is an SEL Premium R-Line or SEL Premium R-Line 4Motion still using the 255/40R20 fitment. In this size, available product choice shown here includes a BFGoodrich g-Force Phenom T/A Blackwall radial, with an 8.5 to 10 inch rim-width range and a maximum load capacity of 1819 lbs at 50 psi.
Those details help frame the comparison, but they do not replace a vehicle check. The wheel should match the required diameter and fall within the tire's rim-width range, and the overall setup should be checked for proper clearance and intended use. That is especially important on vehicles with aftermarket wheels or suspension changes.
What sidewall styles are available for 2018 Volkswagen Trucks Tiguan tires?
Current visible product choice for the 2018 Volkswagen Trucks Tiguan includes a Blackwall sidewall style in 255/40R20. That fitment appears on SEL Premium R-Line models, where sidewall presentation stays clean and modern rather than using a whitewall, stripe, or raised-letter vintage treatment.
Sidewall style matters mostly as an appearance decision once the correct size is confirmed. A Tiguan owner should first match the proper trim-specific tire size and wheel diameter, then compare how the available sidewall treatment fits the vehicle's look. On a newer crossover like this one, the visual choice is typically subtler than on collector-era vehicles.
What brands offer tires for the 2018 Volkswagen Trucks Tiguan?
BFGoodrich appears among the available tire options for the 2018 Volkswagen Trucks Tiguan, specifically in the 255/40R20 fitment used on SEL Premium R-Line models. The tire series shown in that size is the g-Force Phenom T/A, a radial Blackwall product with a more contemporary performance-oriented presentation.
Brand comparison only helps after the correct size has been confirmed, since the Tiguan uses several different fitments across its trim range. A buyer should narrow the search by exact sub-model, wheel diameter, and tire size first, then compare brand, series, sidewall style, and wheel-width compatibility within the appropriate fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Volkswagen Trucks Tiguan?
Yes, modifications can affect tire fitment on a 2018 Volkswagen Trucks Tiguan even when the replacement tire matches one of the model year's original sizes. Aftermarket wheels, suspension changes, lowering, spacers, or body alterations can change clearance at the fender, suspension, and steering points.
That matters even more on this Tiguan because the lineup already spans 17-inch through 20-inch wheel packages, including two different 19-inch sizes. A modified vehicle should be checked by actual wheel diameter, width, and current tire size rather than by trim alone. Reading the sidewall and inspecting available clearance before replacement helps prevent expensive mistakes.
What should I inspect before driving a 2018 Volkswagen Trucks Tiguan on new tires?
Before driving a 2018 Volkswagen Trucks Tiguan on new tires, confirm that all four tires match the intended size for the exact sub-model and that they are mounted on the correct wheel diameter. Tire pressure should be set properly, and the wheels should be inspected for damage, uneven seating, or any visible issue around the bead area.
A short visual and road check is also worthwhile. Look for adequate clearance during steering and suspension movement, especially if the vehicle has non-original wheels or has moved between trim-level wheel packages. After the first drives, recheck pressure and inspect for rubbing, unusual wear, or air loss so small fitment problems do not go unnoticed.
How often should tires on a 2018 Volkswagen Trucks Tiguan be inspected?
Tires on a 2018 Volkswagen Trucks Tiguan should be inspected regularly for pressure loss, tread wear, cuts, bulges, and sidewall damage. Even on a newer vehicle, routine checks matter because the Tiguan's trim-specific tire packages can mask problems if the owner focuses only on wheel appearance rather than on actual tire condition.
A quick inspection every month and before longer drives is a sensible habit, especially on vehicles that see mixed city and highway use. It also helps to inspect any time the vehicle has contacted a pothole or curb. Uneven wear or repeated pressure loss can point to alignment, wheel, or fitment issues that deserve closer attention.
