The 2017 Fiat Trucks 500X brought Fiat’s small crossover formula into a market that expected city-friendly dimensions with a more versatile stance and available all-wheel drive. Its tire fitment reflects that mix, with several radial sizes used across Lounge, Pop, and Trekking configurations on 16-, 17-, and 18-inch rims. Some versions center on a comfort-oriented 215-section fitment, while others move to lower-profile 18-inch sizing such as 225/45R18. That means the real decision is not just tire size, but matching the exact sub-model and wheel setup, then choosing the right tire character for everyday road use, appearance, and overall fitment confidence.
Which Tire Size Is Right for The 2017 Fiat Trucks 500X
The 2017 Fiat Trucks 500X uses five primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Fitment varies across Lounge, Pop, and Trekking versions, with 16-, 17-, and 18-inch rims all in the mix. Before choosing a tire, confirm the sub-model and verify the actual wheel size currently on the vehicle, especially if it may have been changed from stock.
215/55R18 is a metric radial size with a 215-millimeter section width, a 55-series profile, radial construction, and an 18-inch rim diameter. On the 2017 Fiat Trucks 500X, this size is part of the larger-wheel fitment used on certain configurations and gives the vehicle a lower-profile look than the taller 17- and 16-inch alternatives. Product choices are not shown here, so the main focus is confirming that the vehicle actually carries the 18-inch wheel setup. It is a size to evaluate carefully when appearance, wheel diameter, and the exact sub-model all need to line up.

215/60R17 is a metric radial size that pairs a 215-millimeter section width with a 60-series profile on a 17-inch rim. For the 2017 Fiat Trucks 500X, this size appears on several AWD-related applications and represents one of the more substantial sidewall profiles used on the model. No product assortment is shown here for this fitment, so the key decision is making sure the vehicle uses the correct 17-inch wheel before moving further. It is a practical size to confirm when the goal is staying with the proper wheel diameter and fitment pattern for the exact version of the 500X.

215/55R17 is a metric radial size with a 215-millimeter section width, a 55-series sidewall, and a 17-inch rim diameter. On the 2017 Fiat Trucks 500X, it serves specific FWD applications and sits between the taller 215/60R17 and the lower-profile 18-inch choices. Available products in this size come from BFGoodrich in blackwall form across the g-Force Comp 2 AS and g-Force Phenom T/A series. It is a useful fitment to compare when the vehicle already wears 17-inch wheels and the buyer wants to weigh series differences, load details, and rim-width compatibility within the correct size.
225/45R18 is a metric radial size that uses a wider 225-millimeter section width, a 45-series profile, and an 18-inch rim. On the 2017 Fiat Trucks 500X, this size is tied to specific FWD configurations that use the sportier-looking 18-inch setup rather than the narrower 215-section alternatives. Product options include blackwall tires from BFGoodrich and Nitto, with choices across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 lines. This size deserves close attention when wheel diameter, rim width, and the exact sub-model all matter to selecting the right tire.
215/60R16 is a metric radial tire size with a 215-millimeter section width, a 60-series profile, and a 16-inch rim diameter. For the 2017 Fiat Trucks 500X, it appears on a specific Pop FWD fitment and stands apart from the 17- and 18-inch wheel packages used elsewhere in the range. No matching product assortment is shown here, so the important step is confirming that the vehicle still has its 16-inch wheel setup before choosing a replacement tire. It is the size to focus on when preserving the proper wheel-and-tire relationship for that configuration.
Tire fitment on the 2017 Fiat Trucks 500X is not uniform across the lineup, and several sub-models use more than one wheel-and-tire package. Checking the exact Lounge, Pop, or Trekking configuration matters because the correct tire can change with drivetrain and wheel diameter.

2017 Fiat Trucks 500X Lounge (AWD)
The 2017 Fiat Trucks 500X Lounge (AWD) uses radial fitments tied to either a 17-inch or 18-inch wheel package. Tire selection starts with confirming which wheel diameter is on the vehicle now, then choosing a replacement that matches that setup rather than assuming every Lounge AWD uses the same size.
The 2017 Fiat Trucks 500X Lounge (FWD) uses radial tires in two distinct fitments, one on a 17-inch rim and another on an 18-inch rim. That makes wheel verification essential before replacement, especially since the 18-inch option also shifts to a wider, lower-profile tire.
The 2017 Fiat Trucks 500X Pop (AWD) has the simplest fitment pattern in the range, using one radial tire size on a 17-inch wheel. The main decision here is selecting the right tire within that size rather than sorting through multiple primary fitments.
The 2017 Fiat Trucks 500X Pop (FWD) uses radial tires but can be found with either a 16-inch or 17-inch fitment. Tire choice depends first on confirming the actual wheel diameter, since that determines which of the two primary sizes belongs on the vehicle.
The 2017 Fiat Trucks 500X Trekking (AWD) shares the same basic fitment pattern as the AWD Lounge, with radial tire options tied to 17-inch and 18-inch wheels. Replacement decisions should begin with wheel confirmation, then move to selecting the right tire style and specifications within the proper size.
The 2017 Fiat Trucks 500X Trekking (FWD) uses one of two radial fitments depending on whether the vehicle has the 17-inch or 18-inch package. That means the correct tire is determined by the exact wheel setup, not by the Trekking name alone.
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 2017 Fiat Trucks 500X?
The 2017 Fiat Trucks 500X uses five primary tire sizes: 215/55R18, 215/60R17, 215/55R17, 225/45R18, and 215/60R16. All of them are radial sizes, and the correct one depends on the exact Lounge, Pop, or Trekking configuration along with whether the vehicle is FWD or AWD.
The safest starting point is to confirm the exact sub-model and the wheel diameter currently on the vehicle. Since the 500X can use 16-, 17-, or 18-inch rims, replacing tires by model name alone can lead to choosing the wrong size for the actual wheel setup.
What size rim does a 2017 Fiat Trucks 500X use?
A 2017 Fiat Trucks 500X can use 16-inch, 17-inch, or 18-inch rims depending on the sub-model and tire package. The tire sizes attached to those diameters include 215/60R16 on 16-inch rims, 215/60R17 and 215/55R17 on 17-inch rims, and 215/55R18 or 225/45R18 on 18-inch rims.
Rim diameter should be confirmed before anything else because it determines which tire sizes are even possible. Looking at the sidewall size already on the vehicle and verifying the wheel itself is especially important if the 500X has changed hands or may have had wheels swapped.
Why does the 2017 Fiat Trucks 500X have more than one tire size?
The 2017 Fiat Trucks 500X has more than one tire size because fitment changes across Lounge, Pop, and Trekking versions, and some sub-models use alternate wheel packages. That creates a mix of 16-, 17-, and 18-inch applications, along with differences in profile and, in one case, section width.
This matters because the right tire is tied to the specific configuration rather than the 500X name by itself. A buyer should identify the exact sub-model, confirm whether the vehicle is FWD or AWD, and check the current wheel diameter before narrowing down tire choices.
Choosing the Right Tire
What should I consider when choosing a 2017 Fiat Trucks 500X tire?
Start with the correct primary size for the exact 2017 Fiat Trucks 500X sub-model and wheel diameter, then compare the construction and specifications within that size. Since this model uses only radial tires, the main variables are size, rim-width compatibility, load details where shown, and the tire series available for that fitment.
A practical choice depends on how the vehicle is used and which wheel package it carries. One 500X may need a 16-inch replacement, while another may use a lower-profile 18-inch tire, so the selection process should begin with fitment confirmation before comparing individual product characteristics.
What brands offer tires for the 2017 Fiat Trucks 500X?
The available products shown for the 2017 Fiat Trucks 500X come from BFGoodrich and Nitto. BFGoodrich appears in both 215/55R17 and 225/45R18, while Nitto is represented in 225/45R18 among the currently visible options.
Brand comparison only matters after the correct tire size is confirmed for the vehicle’s wheel and sub-model. Once that is settled, the buyer can look at differences in tire series, load information where available, and rim-width range to decide which option best matches the intended use of the 500X.
What tire series are available for the 2017 Fiat Trucks 500X?
The visible tire series for the 2017 Fiat Trucks 500X include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, BFGoodrich g-Force Sport Comp 2, and Nitto NT555 G2. These appear across the 215/55R17 and 225/45R18 fitments and give buyers several ways to compare tires within the correct size.
Series differences are most useful once the size is locked in, because the 500X does not use one universal fitment. After confirming the proper tire size and wheel diameter, compare the series by their sidewall presentation, rim-width suitability, and any load or weight details that matter to the setup.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Fiat Trucks 500X?
A period-style approach for a 2017 Fiat Trucks 500X starts with keeping the correct original-type size and wheel diameter for the exact sub-model, since this vehicle belongs to a modern radial era rather than a bias-ply restoration era. Staying with the proper 16-, 17-, or 18-inch fitment matters more than chasing a vintage-style sidewall treatment.
Visual consistency comes from preserving the intended stance and profile of the vehicle’s existing package. If originality matters closely, compare the current wheel-and-tire setup to vehicle-specific historical references before changing sizes, because a different rim diameter can alter the look of the 500X more than brand choice alone.
Does correct tire fitment matter for a 2017 Fiat Trucks 500X restoration?
Correct tire fitment matters on a 2017 Fiat Trucks 500X because the model uses several distinct radial sizes across different sub-models and wheel packages. A restoration-minded replacement should begin with the proper tire size and rim diameter for the exact configuration, not simply any tire that looks close on the vehicle.
Proper fitment helps preserve the vehicle’s intended proportions and avoids mixing a 16-, 17-, or 18-inch package with the wrong tire profile. For a carefully presented 500X, confirm the sub-model, drivetrain, and wheel setup first, then compare available radial products within that exact size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Fiat Trucks 500X?
Yes, modifications can affect tire fitment on a 2017 Fiat Trucks 500X. Wheel changes, suspension alterations, lowering, or body modifications can change the space available for the original tire size, especially on versions that already use lower-profile 18-inch fitments such as 215/55R18 or 225/45R18.
Even when the tire size matches a factory application, aftermarket wheel width or offset can change clearance at the fender, strut, or steering components. Any modified 500X should have the wheel diameter, tire size, and turning clearance checked together rather than assuming a stock fitment still applies without adjustment.
What should I inspect before driving a 2017 Fiat Trucks 500X on new tires?
Before driving a 2017 Fiat Trucks 500X on new tires, inspect the wheel diameter and confirm the new tires match the correct size for the vehicle’s sub-model and current wheel setup. It also makes sense to check air pressure, verify even seating on the rim, and look for any obvious rubbing or clearance concerns.
A short local drive is useful for confirming that steering feels normal and that nothing contacts the inner fender or suspension during turns. Rechecking pressure after installation and watching for any early air loss can help catch mounting or valve issues before the vehicle goes into regular use.
How often should tires on a 2017 Fiat Trucks 500X be inspected?
Tires on a 2017 Fiat Trucks 500X should be inspected regularly rather than only when tread looks low. Routine checks should include pressure, tread wear, cuts, bulges, sidewall damage, and any signs of uneven wear that could point to alignment, suspension, or wheel issues.
A quick visual inspection before longer trips is especially worthwhile on a vehicle that may alternate between city use and highway driving. Keeping an eye on wear patterns also helps confirm that the chosen tire size is working correctly with the vehicle’s wheel setup and that no clearance problem is developing over time.
