The 2018 Kia Trucks Sportage sits in the compact crossover segment, where daily comfort, tidy exterior dimensions, and modern road manners matter just as much as utility. Buyers usually know the Sportage by trim, because wheel and tire fitment changes across the lineup in a meaningful way. This model uses radial tires throughout, with 225/60R17, 225/55R18, and 245/45R19 sizes tied to different sub-models. That creates different visual and driving personalities, from a narrower 17-inch setup with a narrow whitewall option to blackwall performance-oriented 19-inch choices. The key step is confirming the exact trim and wheel diameter before comparing sidewall style, tire series, or load-related specifications.
Which Tire Size Is Right for The 2018 Kia Trucks Sportage
Three primary tire sizes apply to the 2018 Kia Trucks Sportage, and the correct one depends on the exact sub-model and wheel diameter. The lineup uses radial construction throughout, but the LX, EX, and SX Turbo do not share the same size. Before choosing a tire, confirm whether the Sportage is riding on 17-inch, 18-inch, or 19-inch wheels and match the tire to that setup first.
The 225/55R18 size uses modern metric radial sizing: 225 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2018 Kia Trucks Sportage, this size represents an 18-inch radial fitment rather than a vintage or specialty format. The main consideration here is matching the tire to the correct wheel diameter and trim level before comparing options. This size is the right place to start when the Sportage carries the 18-inch wheel setup used on the applicable sub-model.
The 225/60R17 code describes a radial tire that is 225 millimeters wide, with a 60-series profile, built for a 17-inch rim. On this Sportage fitment, it pairs modern radial construction with the 17-inch wheel setup used on the corresponding sub-model. Available choices in this size include a Travelstar UN106 with a narrow whitewall treatment, which gives this otherwise modern fitment a more distinctive appearance than a typical blackwall tire. It is the size to evaluate when the vehicle has 17-inch wheels and the buyer wants to balance correct fitment with sidewall presentation.
The 245/45R19 designation means a radial tire with a 245-millimeter nominal section width, a 45-series profile, and a 19-inch rim diameter. For the 2018 Kia Trucks Sportage, this size is tied to the 19-inch wheel fitment used on the applicable sub-model and has a broader, lower-profile look than the smaller wheel packages. Product choices in this size include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the size to confirm when the Sportage carries the largest factory-style wheel diameter in the lineup.
Sub-model fitment matters on the 2018 Kia Trucks Sportage because each covered trim uses its own tire size and wheel diameter. Identifying whether the vehicle is an LX, EX, or SX Turbo is the first step before comparing tire style, construction details, or available product choices.

2018 Kia Trucks Sportage EX
The 2018 Kia Trucks Sportage EX uses the 225/55R18 radial fitment, placing it on an 18-inch wheel package rather than the 17-inch or 19-inch setups used elsewhere in the range. Tire selection starts with confirming that wheel diameter, then choosing an appropriate radial tire for the intended appearance and road use.
The 2018 Kia Trucks Sportage LX uses the 225/60R17 radial size on a 17-inch wheel. That makes this trim the one to check if a narrower-profile whitewall presentation is part of the buying decision, while still keeping the primary focus on matching the tire to the correct wheel setup.
The 2018 Kia Trucks Sportage SX Turbo uses the 245/45R19 radial fitment, which is the 19-inch setup in this lineup. Buyers should confirm the wheel diameter first, then compare the available blackwall performance-oriented tire series within that size.
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 2018 Kia Trucks Sportage?
The 2018 Kia Trucks Sportage uses three different tire sizes depending on sub-model: 225/60R17, 225/55R18, and 245/45R19. All three are radial sizes, and each one corresponds to a different wheel diameter, so there is not a single universal tire size across the full Sportage lineup.
The practical step is to identify the exact trim and confirm the wheel diameter already on the vehicle before selecting a tire. The LX uses the 17-inch setup, the EX uses the 18-inch setup, and the SX Turbo uses the 19-inch setup. If the vehicle has had wheel changes, the current wheel size matters more than trim assumptions.
What size rim does a 2018 Kia Trucks Sportage use?
A 2018 Kia Trucks Sportage can use 17-inch, 18-inch, or 19-inch rims, depending on sub-model. The LX uses a 17-inch fitment with 225/60R17 tires, the EX uses an 18-inch fitment with 225/55R18 tires, and the SX Turbo uses a 19-inch fitment with 245/45R19 tires.
Rim diameter is the first thing to confirm because each tire size is built for a specific wheel size and cannot be mixed casually across the lineup. It also helps to check actual wheel markings if the Sportage has aftermarket wheels, since visual guesses between 17-, 18-, and 19-inch setups are not always reliable once tire sidewall height changes.
Why does the 2018 Kia Trucks Sportage have more than one tire size?
The 2018 Kia Trucks Sportage has more than one tire size because different sub-models use different wheel packages. The LX carries 225/60R17, the EX uses 225/55R18, and the SX Turbo uses 245/45R19. All are radial fitments, but they are tied to trim-specific wheel diameters and tire proportions.
That means the right choice is not based on model name alone. Tire selection starts by matching the size to the exact trim and the wheels currently on the vehicle. A Sportage that has been upgraded or changed by a previous owner should be checked carefully, since trim-level expectations do not override the actual wheel diameter mounted on the vehicle.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Kia Trucks Sportage?
Start with the correct tire size for the exact Sportage sub-model and wheel diameter: 225/60R17, 225/55R18, or 245/45R19. From there, compare construction details, sidewall style, rim-width specifications where stated, and load-related figures such as 1709 lbs @ 44psi for the Travelstar 225/60R17 or 1874 lbs at 50 psi for one BFGoodrich 245/45R19 option.
The next decision is about how the vehicle will be used and how you want it to look. A narrow whitewall changes the visual character of the 17-inch setup, while the 19-inch blackwall choices lean toward a more contemporary performance appearance. Matching size first, then comparing specifications and presentation, keeps the selection process straightforward.
What sidewall styles are available for 2018 Kia Trucks Sportage tires?
Two sidewall styles appear among the available 2018 Kia Trucks Sportage tire choices: narrow whitewall and blackwall. The 225/60R17 Travelstar option uses a narrow whitewall, while the available 245/45R19 BFGoodrich and Nitto choices use blackwall sidewalls.
Sidewall style affects appearance more than fitment, but it still matters because it changes the overall look of the vehicle. A whitewall can give the 17-inch setup a more distinctive presentation, while blackwall keeps a cleaner modern look on the 19-inch fitment. The key is making sure the preferred sidewall treatment is available in the exact size your Sportage uses.
What brands offer tires for the 2018 Kia Trucks Sportage?
Available brands for the 2018 Kia Trucks Sportage include Travelstar, BFGoodrich, and Nitto. Travelstar appears in 225/60R17, while BFGoodrich and Nitto appear in 245/45R19. Those choices also bring different tire series into the mix, including UN106, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2.
Brand choice should come after confirming the correct tire size and wheel diameter for the specific trim. Once that is settled, compare the tire series, sidewall style, and any stated rim-width or load-related figures that matter to your use. A Sportage on 17-inch wheels is shopping a different group of products than one on 19-inch wheels.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Kia Trucks Sportage?
A period-style approach on a 2018 Kia Trucks Sportage usually means staying with the correct trim-specific size and choosing a sidewall treatment that suits the look you want. Among the available choices, the 225/60R17 Travelstar with a narrow whitewall creates a more distinctive visual presentation than the blackwall 245/45R19 performance-oriented options.
Appearance should still follow proper fitment. Confirm whether the Sportage is an LX, EX, or SX Turbo and match the tire to the wheel diameter already on the vehicle. Since 2018 is a modern application rather than a traditional restoration-era vehicle, period-style here is more about visual character than reproducing a documented factory-delivered tire presentation.
How does tire construction affect the appearance of a restored 2018 Kia Trucks Sportage?
On the 2018 Kia Trucks Sportage, construction does not create a bias-ply-versus-radial appearance decision because the primary fitments are radial throughout. The bigger appearance differences come from tire size, wheel diameter, profile, and sidewall treatment, especially the contrast between the narrow whitewall 17-inch option and the blackwall 19-inch selections.
That makes trim and wheel package more important than construction when shaping the finished look. A lower-profile 245/45R19 setup naturally presents differently from a 225/60R17, even before brand or series enters the picture. For a restoration-minded owner, preserving the correct size and wheel relationship is the strongest foundation for an authentic-looking result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Kia Trucks Sportage?
Yes, modifications can affect tire fitment on a 2018 Kia Trucks Sportage. Wheel changes, different offsets, suspension lowering, and other aftermarket alterations can change clearance even when the tire size looks close to the original LX, EX, or SX Turbo fitment. That matters because this model already uses three distinct tire and wheel combinations from the factory-style lineup.
A modified Sportage should be checked at the wheel itself rather than by trim assumptions alone. Confirm the actual wheel diameter and width, then look for enough clearance at the strut, fender, and steering range. Even small setup changes can matter more on the 19-inch fitment, where the lower-profile tire leaves less visual room for error.
What should I inspect before driving a 2018 Kia Trucks Sportage on new tires?
Before driving a 2018 Kia Trucks Sportage on new tires, inspect the wheel diameter and size match, confirm proper inflation, and look over the tires for any shipping or mounting damage. It is also smart to verify valve condition, lug torque, and basic clearance around the fenders and suspension once the vehicle is back on the ground.
A short local drive followed by a second inspection is a sensible next step. Recheck pressure, make sure there is no rubbing at full steering lock, and watch for any vibration that could point to balancing or wheel issues. On a Sportage with replacement wheels, this first follow-up check is especially useful after moving between 17-, 18-, or 19-inch setups.
How often should tires on a 2018 Kia Trucks Sportage be inspected?
Tires on a 2018 Kia Trucks Sportage should be inspected regularly rather than only when a problem appears. A quick visual check for air loss, cuts, bulges, uneven wear, or sidewall damage is worth doing often, especially before longer trips. Pressure should also be checked routinely, since modern radial tires can look acceptable even when underinflated.
A more careful inspection makes sense any time the vehicle has sat for a while, hit a pothole, or had wheel service performed. Pay extra attention if the Sportage has aftermarket wheels or if one trim-specific tire size has been swapped for another wheel package. Catching wear or clearance issues early is much easier than diagnosing them after damage occurs.
