The 2018 Kia Trucks Sorento sits in the modern three-row crossover segment, balancing family use, daily driving, and a more substantial road presence than a compact SUV. Buyers usually arrive here needing to sort out trim-specific wheel and tire fitment rather than choosing between vintage constructions or restoration themes. This Sorento uses radial tires in three primary sizes: 235/65R17, 235/60R18, and 235/55R19, depending on sub-model. That makes the first decision identifying the exact trim and confirming wheel diameter. Once that is settled, the choice becomes finding the right tire within the correct size for appearance, driving use, and overall fitment confidence.
Which Tire Size Is Right for The 2018 Kia Trucks Sorento
The 2018 Kia Trucks Sorento uses three primary tire sizes, and they are tied directly to sub-model and wheel diameter. 235/65R17, 235/60R18, and 235/55R19 are all radial fitments, so the first step is confirming the exact trim and whether the Sorento is on 17-inch, 18-inch, or 19-inch wheels before selecting a replacement tire.
A 235/60R18 tire uses a 235-millimeter section width, a 60-series aspect ratio, radial construction, and an 18-inch wheel. On the 2018 Kia Trucks Sorento, this size is part of the trim-specific factory-style radial fitment and keeps the buyer focused on the correct wheel diameter first. Its proportions place it close in overall height to the Sorento's other primary sizes, but it is still a distinct fitment tied to specific sub-models. Choose this size when the vehicle is already equipped with the proper 18-inch wheel setup and the trim calls for this configuration.
A 235/65R17 tire pairs a 235-millimeter section width with a 65-series profile, radial construction, and a 17-inch rim. For the 2018 Kia Trucks Sorento, this size serves the trims that use the smaller wheel diameter among the three primary fitments. The taller sidewall relative to the 18-inch and 19-inch options is part of the size's own design format, but it should still be treated as its own trim-based application rather than as a casual substitute. This is the size to evaluate when the Sorento has the correct 17-inch wheels and matching sub-model fitment.
A 235/55R19 tire keeps the same 235-millimeter nominal width but uses a lower 55-series profile on a 19-inch wheel, with radial construction. On the 2018 Kia Trucks Sorento, this size belongs to the trims equipped with the largest primary wheel diameter in the range. It gives the buyer a distinctly different wheel-and-tire package from the 17-inch and 18-inch setups, even though the overall tire height remains in a similar range. This is the correct direction to pursue when the Sorento's trim and wheel package call for the 19-inch fitment.
Sub-model fitment matters on the 2018 Kia Trucks Sorento because tire size changes with trim. The main job here is matching the exact Sorento sub-model to its wheel diameter before comparing replacement tires within the correct radial size.

2018 Kia Trucks Sorento EX 2.0
The 2018 Kia Trucks Sorento EX 2.0 uses the 235/60R18 radial fitment. Tire selection starts with confirming the 18-inch wheel package, then narrowing choices within that size for the driving feel and replacement style that best suits the vehicle.
The 2018 Kia Trucks Sorento EX V6 also uses the 235/60R18 radial size. That keeps the fitment process straightforward as long as the Sorento remains on the correct 18-inch wheels and has not been changed to an aftermarket wheel setup.
The 2018 Kia Trucks Sorento L uses the 235/65R17 radial fitment. Buyers should stay focused on the 17-inch wheel diameter first, then compare replacement tires in that exact size rather than assuming the larger-wheel trims share the same fitment.
The 2018 Kia Trucks Sorento LX uses 235/65R17 radial tires. That means the right replacement path begins with confirming the 17-inch wheel size and selecting within that fitment instead of crossing into the 18-inch or 19-inch trim packages.
The 2018 Kia Trucks Sorento LX V6 uses the same 235/65R17 radial fitment as other 17-inch-wheel trims. Tire shopping is simplest when the wheel setup is still original, but any wheel change should be checked carefully before choosing a replacement size.
The 2018 Kia Trucks Sorento SX uses the 235/55R19 radial size. This trim's tire choice depends on staying with the correct 19-inch wheel package and verifying that any prior wheel or suspension changes have not altered clearance requirements.
The 2018 Kia Trucks Sorento SX Limited uses 235/55R19 radial tires. Buyers should confirm the 19-inch wheel diameter first, then compare replacement tires within that size for the right balance of fitment accuracy and intended road use.
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
These 2018 Kia Trucks Sorento tire questions focus on trim-specific sizing, wheel diameter, choosing the correct radial fitment, and the checks that matter before replacing tires on a daily-driven or lightly modified Sorento.
Tire Size & Fitment
What tire size fits a 2018 Kia Trucks Sorento?
The 2018 Kia Trucks Sorento uses three primary tire sizes: 235/65R17, 235/60R18, and 235/55R19. The correct size depends on the exact sub-model, with L, LX, and LX V6 using 235/65R17, EX 2.0 and EX V6 using 235/60R18, and SX and SX Limited using 235/55R19.
That means the first step is identifying the trim and confirming the wheel diameter already on the vehicle. A Sorento with replacement wheels or a prior tire change should be checked carefully, because the three sizes use different rim diameters even though their overall heights are close.
What size rim does a 2018 Kia Trucks Sorento use?
A 2018 Kia Trucks Sorento can use 17-inch, 18-inch, or 19-inch rims depending on sub-model. The 235/65R17 fitment uses a 17-inch rim, 235/60R18 uses an 18-inch rim, and 235/55R19 uses a 19-inch rim.
Rim diameter is the most important measurement to confirm before ordering tires, because a 17-inch tire will not mount on an 18-inch or 19-inch wheel. Checking the trim level helps, but it is still smart to verify the actual wheel on the vehicle, especially if it has been bought used or modified.
Do all 2018 Kia Trucks Sorento sub-models use the same tire size?
No. The 2018 Kia Trucks Sorento uses different tire sizes across its sub-model range. L, LX, and LX V6 use 235/65R17, EX 2.0 and EX V6 use 235/60R18, and SX plus SX Limited use 235/55R19.
That variation is tied to wheel diameter, so trim identification matters before any tire purchase. Even when two sizes appear close in overall dimensions, they are not the same fitment. Checking the current wheel size, the trim badge, and the existing tire sidewall helps keep the replacement process accurate.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Kia Trucks Sorento?
Start with the correct trim-specific size: 235/65R17, 235/60R18, or 235/55R19. The Sorento uses radial tires across all three fitments, so the essential first decision is matching the tire to the wheel diameter already on the vehicle rather than comparing unrelated sizes.
After that, look at how the Sorento is used. A family vehicle that sees daily commuting, highway travel, or occasional cargo duty should have tires selected with proper size, load suitability, and wheel compatibility in mind. Vehicles with aftermarket wheels or suspension changes deserve an extra clearance and fitment check before replacement.
How do I choose between the available 2018 Kia Trucks Sorento tire sizes?
The three Sorento tire sizes are not interchangeable choices to pick by preference alone. Each one belongs to specific sub-models and wheel diameters: 17-inch, 18-inch, or 19-inch. The right choice is the size that matches the vehicle's actual trim and wheel setup.
That makes the process more about verification than experimentation. Check the tire sidewall currently on the vehicle, confirm the wheel diameter, and compare that with the Sorento sub-model. If the vehicle was purchased used, changed to different wheels, or has uneven replacement history, inspect all four corners before selecting new tires.
What rim-fitment details matter when choosing tires for a 2018 Kia Trucks Sorento?
The key rim-fitment detail on a 2018 Kia Trucks Sorento is wheel diameter. The vehicle uses 17-inch rims with 235/65R17 tires, 18-inch rims with 235/60R18 tires, and 19-inch rims with 235/55R19 tires, depending on sub-model.
Beyond diameter, the actual wheel setup should still be inspected before replacement. A Sorento with aftermarket wheels, non-original offsets, or suspension changes can create different clearance conditions than a stock vehicle. Matching the tire to the real wheel on the vehicle helps avoid ordering a size that belongs to a different trim package.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Kia Trucks Sorento restoration or refurbishment?
Yes. Even on a modern vehicle like the 2018 Kia Trucks Sorento, correct tire fitment matters when returning the vehicle to a clean, factory-inspired appearance. The right trim-specific size keeps the wheel-and-tire package visually consistent with the vehicle's intended stance and avoids mixing fitments from other sub-models.
A refurbishment-minded buyer should confirm whether the Sorento still has its proper 17-inch, 18-inch, or 19-inch wheels before choosing tires. That is especially important on used vehicles, where one previous owner may have changed wheels while another simply replaced tires to match what was already installed.
How does tire size affect the appearance of a 2018 Kia Trucks Sorento?
Tire size affects how much sidewall is visible and how the wheel fills the opening on a 2018 Kia Trucks Sorento. The 235/65R17 setup presents more sidewall around a smaller wheel, while 235/60R18 and 235/55R19 move progressively toward larger wheel diameter and a shorter visible sidewall.
That visual difference is one reason trim-correct sizing matters. Choosing the proper size for the Sorento's actual wheel package helps maintain the intended look, while mixing sizes across trims can change the vehicle's presentation even if the overall tire height remains in a similar range.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Kia Trucks Sorento?
Yes. Modifications can affect tire fitment on a 2018 Kia Trucks Sorento even when the original trim used one of the standard sizes. Wheel changes, different offsets, suspension lowering, lift components, or body alterations can all change clearance and may alter which tire size works safely on the vehicle.
A modified Sorento should be checked at the wheel, not just by trim name. Verifying wheel diameter, observing sidewall and suspension clearance, and checking full steering travel are important before replacing tires. That extra step matters most when the vehicle no longer retains its original wheel-and-tire package.
What should I inspect before driving a 2018 Kia Trucks Sorento on new tires?
Before driving a 2018 Kia Trucks Sorento on new tires, inspect the wheel diameter, tire size, and basic installation details at all four corners. The tire should match the Sorento's actual wheel package, and the sidewalls should be free from damage or rubbing once the vehicle is back on the ground.
A short follow-up inspection is also worthwhile after the first miles. Check inflation pressure, listen for contact during turns, and look for uneven clearance around suspension and fender areas. On a used or previously modified Sorento, those simple checks help confirm that the replacement size truly matches the vehicle's setup.
How often should tires on a 2018 Kia Trucks Sorento be inspected?
Tires on a 2018 Kia Trucks Sorento should be inspected regularly, not just when replacement time arrives. Routine checks should include tread wear, visible cracking, cuts, bulges, and pressure loss, especially because a trim-specific size mistake can sometimes go unnoticed until uneven wear or clearance issues appear.
A monthly visual check is a sensible habit, along with inspection before longer highway travel. Sorentos that sit for extended periods, carry family or cargo loads, or run on non-original wheels deserve extra attention. Consistent inspection helps catch age, inflation, and fitment issues before they turn into road-use problems.
