The 2019 Fiat Trucks 500X blends compact crossover practicality with Fiat’s smaller European-flavored design language, making it a distinctive choice for drivers who want something more characterful than a typical utility vehicle. Its stance and proportions mean tire fitment plays a real role in both appearance and everyday road manners. For this model year, the 500X uses radial tires in two primary sizes, 215/60R17 and 215/55R18, depending on sub-model and wheel setup. That makes the key decision less about vintage-style construction and more about confirming the exact trim and rim diameter first. Once that is settled, the focus shifts to maintaining the intended fit, ride, and clearance.
Which Tire Size Is Right for The 2019 Fiat Trucks 500X
The 2019 Fiat Trucks 500X uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Both fitments are radial, but one uses a 17-inch rim and the other uses an 18-inch rim, so confirming the actual wheel on the vehicle is the first step before comparing tire choices.
215/60R17 is a metric radial size where 215 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2019 Fiat Trucks 500X, this size is part of the primary fitment range and is tied to specific sub-model and wheel combinations. Its dimensions make it a distinct fitment choice rather than an interchangeable alternative to the 18-inch setup. This is the size to evaluate when the vehicle is equipped with 17-inch wheels and the goal is to preserve the intended wheel-and-tire relationship.
Fit(s): Trekking, Trekking Plus, and Trekking Urbana Pkg.
Construction: Radial|Rim: 18 in
215/55R18 is also a metric radial size, using the same 215-millimeter nominal width but a 55-series profile on an 18-inch rim. For the 2019 Fiat Trucks 500X, it serves as the other primary fitment and applies to certain trim and wheel combinations rather than the full model line. The lower profile and larger rim diameter make wheel confirmation especially important before selection. This size belongs on vehicles set up with 18-inch wheels, so buyers should match the tire to the actual rim rather than choosing by model name alone.
Sub-model fitment on the 2019 Fiat Trucks 500X is not completely uniform, because some versions use one size while others appear with either of the two primary sizes. Checking the exact trim and the wheel currently on the vehicle matters before selecting a replacement tire.

2019 Fiat Trucks 500X Pop
The 2019 Fiat Trucks 500X Pop uses the 215/60R17 radial tire fitment. Tire selection for this trim starts with staying on the correct 17-inch wheel setup and then choosing a replacement that preserves the intended size and profile.
The 2019 Fiat Trucks 500X Trekking appears with either 215/60R17 or 215/55R18 radial tires, depending on the wheel package on the vehicle. That makes wheel-diameter confirmation essential before replacement, since the 17-inch and 18-inch fitments are separate primary sizes.
The 2019 Fiat Trucks 500X Trekking Plus also uses either 215/60R17 or 215/55R18 radial tires. Tire choice here depends on verifying which wheel setup the vehicle actually has, then matching the replacement to that exact rim diameter and size code.
The 2019 Fiat Trucks 500X Trekking Urbana Pkg. uses the 215/55R18 radial tire fitment. Replacement selection should center on maintaining the correct 18-inch sizing and confirming that the vehicle has not been changed to a different wheel setup over time.
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
Common tire questions for the 2019 Fiat Trucks 500X center on the two correct sizes, 17-inch versus 18-inch rim fitment, trim-specific selection, and what to inspect before putting the vehicle back into regular road use.
Tire Size & Fitment
What tire size fits a 2019 Fiat Trucks 500X?
The 2019 Fiat Trucks 500X uses two primary tire sizes: 215/60R17 and 215/55R18. Both are radial fitments, but they do not apply universally across every version of the vehicle. The Pop uses 215/60R17, the Trekking Urbana Pkg. uses 215/55R18, and Trekking and Trekking Plus can use either size depending on wheel setup.
The practical next step is to confirm the exact sub-model and the wheel diameter currently on the vehicle before ordering tires. A 17-inch tire and an 18-inch tire are separate fitments, even when the model name is the same. Checking the tire sidewall and the wheel itself helps avoid choosing the wrong size for the vehicle’s actual configuration.
What size rim does a 2019 Fiat Trucks 500X use?
A 2019 Fiat Trucks 500X uses either a 17-inch rim or an 18-inch rim, depending on trim and wheel package. The 215/60R17 tire fits a 17-inch rim, while the 215/55R18 tire fits an 18-inch rim. Both are standard metric radial sizes, and the final number in each size code corresponds to rim diameter in inches.
Rim diameter is the first fitment point to verify because the tire must match the wheel exactly. A 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. Buyers should confirm the actual wheels on the vehicle, especially on Trekking and Trekking Plus models that appear with more than one primary size.
Why does the 2019 Fiat Trucks 500X have more than one tire size?
The 2019 Fiat Trucks 500X has more than one tire size because fitment changes with sub-model and wheel package. Some trims stay with a single setup, while others use either 215/60R17 or 215/55R18. Both sizes are legitimate primary fitments for the model line, but they correspond to different wheel diameters rather than interchangeable replacements.
That means the right tire is determined by the vehicle’s exact configuration, not just by the year and model name. A buyer should identify the trim, check the current wheel diameter, and confirm the size already on the tire sidewall. That simple check matters most on Trekking and Trekking Plus versions, where either fitment may be present.
Choosing the Right Tire
What should I consider when choosing a tire for a 2019 Fiat Trucks 500X?
Start with the correct primary size for the vehicle: 215/60R17 or 215/55R18. The 2019 Fiat Trucks 500X uses radial tires, so the first decision is not construction type but exact fitment. Pop and Trekking Urbana Pkg. models follow a single size, while Trekking and Trekking Plus require confirmation of which wheel-and-tire package is actually on the vehicle.
After size is confirmed, compare the replacement tire’s intended use against how the vehicle is driven. Wheel diameter, profile, and overall fitment should stay aligned with the setup already on the vehicle unless a deliberate change is being evaluated. Buyers should also inspect for prior wheel changes, because an aftermarket setup can alter what size is appropriate now.
How do I choose between the available tire sizes for a 2019 Fiat Trucks 500X?
The two sizes for a 2019 Fiat Trucks 500X are not competing options to choose between freely; they belong to different wheel setups. 215/60R17 is for 17-inch rims, while 215/55R18 is for 18-inch rims. The correct choice comes from the vehicle’s trim and, more importantly, the wheel diameter actually installed on the vehicle today.
That distinction matters because both sizes have similar overall proportions but mount to different rims. Buyers should read the existing sidewall, measure nothing by appearance alone, and verify the wheel before replacing tires. This is especially important on Trekking and Trekking Plus models, where either primary size may be present depending on how the vehicle was equipped.
How do I choose between 215/60R17 and 215/55R18 tires for a 2019 Fiat Trucks 500X?
Choosing between 215/60R17 and 215/55R18 for a 2019 Fiat Trucks 500X begins with the wheel, not preference alone. Each size is designed for a different rim diameter, and both are valid primary fitments within the model range. One belongs to the 17-inch setup and the other to the 18-inch setup, so the vehicle’s current wheels determine the correct starting point.
Once the wheel diameter is confirmed, the goal is to keep the tire matched to that setup unless the vehicle is being intentionally reconfigured. Any wheel change should be evaluated carefully for clearance and overall compatibility before selecting a different size. On an unmodified vehicle, the sidewall marking already on the tire is the quickest guide to the right replacement.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Fiat Trucks 500X restoration or appearance refresh?
Yes, correct tire fitment still matters on a 2019 Fiat Trucks 500X, even though it is a modern crossover rather than a vintage restoration project. The vehicle uses either 215/60R17 or 215/55R18 depending on trim and wheel package, and staying with the proper size helps preserve the intended stance, wheel-to-tire proportion, and everyday usability.
Appearance can change noticeably when the wrong rim diameter or profile is used, especially on a vehicle with trim-specific wheel packages. Anyone refreshing the vehicle cosmetically should confirm whether the goal is to maintain its existing look or return it to a particular factory-style setup. That process starts by verifying the wheels currently installed and matching the tire size accordingly.
How does tire size affect the appearance of a 2019 Fiat Trucks 500X?
Tire size affects both stance and visual balance on a 2019 Fiat Trucks 500X because the model uses either a 17-inch or 18-inch wheel package. A 215/60R17 presents a different sidewall-to-wheel proportion than a 215/55R18, even though both belong to the same vehicle line. That difference is part of the model’s trim-specific appearance.
Buyers who care about presentation should avoid choosing by wheel style alone and confirm the exact size used on the vehicle. Keeping the proper size helps maintain the look intended for that wheel package and avoids an obviously mismatched combination. If the vehicle has been altered with different wheels, appearance and fitment should be reviewed together before replacement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Fiat Trucks 500X?
Yes, modifications can affect tire fitment on a 2019 Fiat Trucks 500X. The original fitment range already includes both 17-inch and 18-inch wheel setups, so aftermarket wheels, suspension changes, or altered ride height can complicate replacement selection. Even when the vehicle started with 215/60R17 or 215/55R18, the current setup may no longer match the original trim configuration.
That is why the actual wheel diameter and the tire size currently mounted should be checked before choosing replacements. Clearance at the fender, suspension, and steering range also matters when a vehicle has been changed from stock form. A quick visual inspection and sidewall check can prevent ordering a size that suits the badge but not the vehicle’s present setup.
What should I inspect before driving a 2019 Fiat Trucks 500X on new tires?
Before driving a 2019 Fiat Trucks 500X on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure inflation is set correctly for the installed tires. It is also wise to check valve stems, lug hardware, and the condition of the suspension and alignment-related components that influence how the new tires will wear.
A short road check afterward can reveal vibration, pull, or rubbing that was not obvious during installation. Buyers should also confirm there is adequate clearance through full steering travel, especially if the vehicle has non-original wheels. Catching these issues early helps protect the new tires and makes sure the vehicle is ready for normal road use.
How often should tires on a 2019 Fiat Trucks 500X be inspected?
Tires on a 2019 Fiat Trucks 500X should be inspected regularly, not only when replacement is due. A routine check for uneven wear, cracking, cuts, punctures, bulges, and air loss helps catch problems early, especially on a vehicle that may see mixed city and highway use. Both 215/60R17 and 215/55R18 fitments deserve the same basic inspection habits.
Monthly pressure checks and visual inspections are a sensible baseline, with another close look before longer drives. Owners should pay extra attention if the vehicle has sat for extended periods or has recently had wheel, brake, or suspension work. Consistent inspection helps confirm that the tire condition still matches the way the 500X is being used on the road.
