The 2019 Alfa Romeo Trucks Stelvio brings Alfa Romeo performance character into a modern sport-utility format, blending sharp styling with trim-specific wheel and tire packages that can change the fitment decision quickly. For this exact Stelvio, tire selection centers on four primary radial sizes: 235/60R18, 235/55R19, 255/45R20, and 285/40R20, depending on the sub-model and axle position. That matters because some versions share one size front and rear, while the Quadrifoglio uses a staggered 20-inch setup. Available choices in 255/45R20 also vary by brand, tire series, and sidewall treatment, so appearance, wheel confirmation, and intended road use all deserve a close look before replacing tires.
Which Tire Size Is Right for The 2019 Alfa Romeo Trucks Stelvio
Four primary tire sizes apply to the 2019 Alfa Romeo Trucks Stelvio, and the right one depends on the exact sub-model and wheel setup. Rim diameter is the first thing to confirm, since this Stelvio can use 18-inch, 19-inch, or 20-inch wheels, and the Quadrifoglio adds a staggered front-and-rear arrangement on 20-inch rims. Once the wheel and sub-model are confirmed, the decision shifts to selecting the appropriate radial tire within that fitment.
A 235/55R19 size uses a 235-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 19-inch rim. On the 2019 Alfa Romeo Trucks Stelvio, this is one of the core modern radial fitments used on several sub-models with 19-inch wheels. It sits in the mainstream crossover and performance-utility sizing range, so the key question is not decoding the format but confirming that the vehicle is actually on the 19-inch package. This size makes the most sense when the Stelvio retains its 19-inch wheel setup and does not use the 18-inch or 20-inch alternatives.
A 235/60R18 tire is a metric radial with a 235-millimeter nominal width, a 60-series profile, and an 18-inch rim diameter. For the 2019 Alfa Romeo Trucks Stelvio, this size belongs to certain Base configurations rather than the full range of trims. Its overall dimensions are close to the other primary Stelvio fitments, but the wheel diameter still makes it a distinct selection that cannot be treated like a 19-inch or 20-inch option. This is the size to evaluate when the vehicle is equipped with 18-inch wheels and the goal is staying with the correct primary fitment.
Fit(s): Base, Quadrifoglio Front, Sport, Ti, Ti Lusso, and Ti Sport
Construction: Radial|Rim: 20 in
A 255/45R20 tire combines a 255-millimeter nominal section width with a 45-series profile, radial construction, and a 20-inch rim. This size appears across several 2019 Alfa Romeo Trucks Stelvio configurations and also serves as the front fitment on the Quadrifoglio. Product choice is strongest here, with BFGoodrich, Nitto, and Pro-Trac options, plus Blackwall, raised white letter, and Redline sidewall treatments across g-Force and Street Pro III series. This size deserves extra attention when appearance matters as much as fitment, especially on a 20-inch wheel package where trim and axle position should be verified first.
A 285/40R20 tire uses a wider 285-millimeter nominal section width, a 40-series profile, radial construction, and a 20-inch rim. On the 2019 Alfa Romeo Trucks Stelvio, this size is tied to the rear of the Quadrifoglio's staggered setup rather than the standard front-and-rear fitments used on other trims. That wider rear sizing is a major reason the exact sub-model and axle position matter before choosing replacement tires. This is the correct size to review when the vehicle is a Quadrifoglio rear application and needs the wider 20-inch rear fitment rather than the narrower front size.
Sub-model fitment matters on the 2019 Alfa Romeo Trucks Stelvio because tire size changes with wheel package, trim, and in one case axle position. Some trims share the same basic size choices, while the Quadrifoglio uses a staggered 20-inch arrangement that should be confirmed before replacing any tire.

2019 Alfa Romeo Trucks Stelvio Base
The 2019 Alfa Romeo Trucks Stelvio Base can use more than one primary radial fitment, including 18-inch, 19-inch, and 20-inch wheel-based sizes. That makes wheel confirmation especially important, since tire selection depends on the actual rim diameter mounted on the vehicle rather than the trim name alone.
The 2019 Alfa Romeo Trucks Stelvio Quadrifoglio Front uses the 255/45R20 radial size as part of a staggered setup. Front tire replacement should be handled with the matching axle position in mind so the wider rear fitment is not confused with the front size.
The 2019 Alfa Romeo Trucks Stelvio Quadrifoglio Rear uses 285/40R20, making it distinct from the front tire size on the same model. Rear replacement should focus on preserving the correct staggered relationship and confirming that the wheel remains the proper rear 20-inch application.
The 2019 Alfa Romeo Trucks Stelvio Sport uses radial fitments tied to either 19-inch or 20-inch wheels. Tire selection is straightforward once the wheel diameter is verified, and that check becomes more important than the trim badge when the vehicle has had wheel changes.
The 2019 Alfa Romeo Trucks Stelvio Ti shares radial size choices found on other 19-inch and 20-inch Stelvio trims. Choosing the right tire starts with confirming which wheel package is actually on the vehicle, then narrowing the decision to the correct size and tire style.
The 2019 Alfa Romeo Trucks Stelvio Ti Lusso uses the same general radial fitment pattern as other 19-inch and 20-inch Stelvio trims. The practical decision is confirming the installed wheel diameter first, then selecting a tire that matches the intended balance of appearance and everyday road use.
The 2019 Alfa Romeo Trucks Stelvio Ti Sport uses radial sizes associated with either 19-inch or 20-inch wheels. Tire selection is easiest once the wheel setup is confirmed, especially since that determines whether the vehicle needs the 235/55R19 fitment or the wider 255/45R20 option.
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 2019 Alfa Romeo Trucks Stelvio?
The 2019 Alfa Romeo Trucks Stelvio uses four primary tire sizes: 235/60R18, 235/55R19, 255/45R20, and 285/40R20. All of them are radial sizes, but they do not apply uniformly across the lineup. Some trims use more than one possible size depending on wheel package, while the Quadrifoglio uses 255/45R20 in front and 285/40R20 in the rear.
The most important step is confirming the exact sub-model and the wheel diameter currently on the vehicle. An 18-inch, 19-inch, or 20-inch Stelvio setup calls for a different tire, and a staggered Quadrifoglio should always be checked by axle position before ordering replacements or rotating existing tires.
What size rim does a 2019 Alfa Romeo Trucks Stelvio use?
A 2019 Alfa Romeo Trucks Stelvio can use 18-inch, 19-inch, or 20-inch rims, depending on the sub-model and tire package. The 235/60R18 fitment uses an 18-inch rim, the 235/55R19 fitment uses a 19-inch rim, and both 255/45R20 and 285/40R20 use 20-inch rims.
That range makes wheel confirmation essential before choosing tires. Looking at the trim badge alone is not always enough, especially on a Base model with multiple possible setups or on a vehicle that may have had wheel changes. Reading the current tire size or measuring the wheel diameter prevents costly mistakes.
Why does the 2019 Alfa Romeo Trucks Stelvio have more than one tire size?
The 2019 Alfa Romeo Trucks Stelvio has more than one tire size because different trims and wheel packages use different diameters and widths. Base, Sport, Ti, Ti Lusso, and Ti Sport configurations can vary by wheel package, while the Quadrifoglio uses a staggered arrangement with one size in front and a wider size in the rear.
That means replacement tires should be matched to the exact setup on the vehicle, not just the year and model name. A 20-inch fitment is not interchangeable with an 18-inch or 19-inch package, and a Quadrifoglio rear tire should never be assumed to match the front without checking the mounted size first.
Choosing the Right Tire
What should I consider when choosing a 255/45R20 tire for a 2019 Alfa Romeo Trucks Stelvio?
Start with confirming that 255/45R20 is the correct fitment for the specific 2019 Alfa Romeo Trucks Stelvio and axle position. This size appears on several 20-inch Stelvio applications and on the front of the Quadrifoglio. Available choices differ by brand, tire series, sidewall style, rim-width specification, weight, and in some cases stated load information.
Once the size is confirmed, the real decision becomes how the tire should look and how the vehicle is used. Blackwall options keep a more contemporary appearance, while raised white letter or Redline versions create a more distinctive presentation. The wheel width should also be checked so the chosen tire matches the mounted rim properly.
What sidewall styles are available for 2019 Alfa Romeo Trucks Stelvio tires?
Within the available 255/45R20 options for the 2019 Alfa Romeo Trucks Stelvio, sidewall styles include Blackwall, raised white letter, and Redline. Blackwall appears on BFGoodrich and Nitto offerings, while Pro-Trac Street Pro III is available in both RWL and Redline form.
Sidewall treatment does not change the primary tire size, but it does change the visual character of the vehicle. A Blackwall tire gives the Stelvio a more understated modern look, while RWL and Redline versions stand out more clearly. The best choice depends on whether appearance or a cleaner OEM-style presentation matters more.
What brands offer tires for the 2019 Alfa Romeo Trucks Stelvio?
For the 2019 Alfa Romeo Trucks Stelvio's available 255/45R20 fitment, brands include BFGoodrich, Nitto, and Pro-Trac. Those choices span more than one tire series, including BFGoodrich g-Force variants, Nitto NT555 G2, and Pro-Trac Street Pro III, all in radial construction.
Brand selection should still come after confirming the actual tire size on the vehicle. Once that is settled, comparing the available series and sidewall treatments usually matters more than the brand name by itself. The most useful approach is matching the tire to the wheel setup, visual preference, and intended road use.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Alfa Romeo Trucks Stelvio?
A period-style approach on a 2019 Alfa Romeo Trucks Stelvio still begins with the correct modern radial size for the trim and wheel package. For 20-inch applications using 255/45R20, the available choices include contemporary Blackwall options as well as more appearance-driven alternatives such as raised white letter and Redline versions.
The right choice depends on how closely the vehicle is being kept to its original visual theme versus a personalized enthusiast look. A cleaner Blackwall presentation usually preserves a more understated appearance, while RWL or Redline adds visual emphasis. The best starting point is always the proper size and wheel fitment before sidewall style.
How does tire construction affect the appearance of a restored 2019 Alfa Romeo Trucks Stelvio?
On the 2019 Alfa Romeo Trucks Stelvio, the primary fitments are all radial, so the appearance difference comes less from construction type and more from tire series and sidewall treatment. In the available 255/45R20 range, Blackwall, raised white letter, and Redline styles each give the vehicle a noticeably different visual character.
That means a restoration-oriented or collector-minded Stelvio owner is really choosing the look within the correct radial fitment rather than deciding between bias-ply and radial presentation. Matching the wheel diameter and exact tire size remains the foundation. After that, sidewall style becomes the main tool for shaping the finished appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Alfa Romeo Trucks Stelvio?
Yes, modifications can affect tire fitment on a 2019 Alfa Romeo Trucks Stelvio even when the tire size itself is correct for a stock application. Aftermarket wheels, offset changes, suspension lowering, spacer use, or body alterations can change clearance at the fender, suspension, and steering components.
That is especially important on 20-inch applications and on the staggered Quadrifoglio setup, where front and rear sizing already differ. A modified Stelvio should be checked with the wheels turned and the suspension loaded so the replacement tire is evaluated against the vehicle's actual wheel position and available clearance.
What should I inspect before driving a 2019 Alfa Romeo Trucks Stelvio on new tires?
Before driving a 2019 Alfa Romeo Trucks Stelvio on new tires, inspect the wheel diameter and tire size against the sub-model, then check the tires for proper mounting, visible bead seating, and correct inflation. It is also smart to look over the wheels for damage and confirm that lug hardware is secure.
A short road test should follow, with attention to rubbing, vibration, and steering behavior. On a Quadrifoglio, verify that the front and rear tires were not mixed during installation. Any Stelvio that has seen wheel changes, curb damage, or suspension work deserves an extra clearance check before regular use resumes.
What should I check before a longer drive in a 2019 Alfa Romeo Trucks Stelvio?
Before a longer drive in a 2019 Alfa Romeo Trucks Stelvio, check tire pressure, tread condition, cuts, bulges, and any signs of uneven wear. The exact tire size should also be verified at all four corners, especially on a Quadrifoglio where front and rear fitments are intentionally different.
Longer trips are also a good time to inspect for slow air loss and to confirm that the tires have enough clearance under full steering lock and normal suspension travel. A Stelvio that spends time parked should be watched for age-related cracking as well, since low mileage does not always mean low tire wear.
