The 2019 Kia Cadenza sits in the modern full-size sedan space with a strong emphasis on quiet highway comfort, clean styling, and upscale everyday use. For many owners, tire selection affects not just appearance, but also how the car delivers the refined road manners expected from a Cadenza. This model uses two primary radial sizes, 245/40R19 and 245/45R18, depending on sub-model and wheel diameter. Available choices center on blackwall performance-oriented radial tires from BFGoodrich and Nitto across several series. The key step is matching the correct size to the exact trim level and wheel setup before comparing tire series, load details, and intended driving use.
Which Tire Size Is Right for The 2019 Kia Cadenza
The 2019 Kia Cadenza uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. Limited and Technology models use a 19-inch setup with 245/40R19, while the Premium uses an 18-inch setup with 245/45R18. Before choosing a tire, confirm the exact trim and verify whether the car still has its original wheel diameter, especially if wheels have been changed.
In 245/45R18, the 245 is the section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 18 denotes the wheel diameter in inches. This radial size belongs to 2019 Kia Cadenza configurations equipped with 18-inch wheels rather than the larger 19-inch setup. Product choices include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to compare when the car is a Premium model or when the wheel diameter on the vehicle confirms an 18-inch application.
Tire fitment for the 2019 Kia Cadenza varies by sub-model, so trim identification matters before selecting a tire. The main difference is wheel diameter, with some trims using 19-inch tires and another using an 18-inch size.

Tire Size & Fitment
What tire size fits a 2019 Kia Cadenza?
A 2019 Kia Cadenza uses either 245/40R19 or 245/45R18, depending on sub-model. The Limited and Technology use 245/40R19, while the Premium uses 245/45R18. Both are radial metric sizes, but they are tied to different wheel diameters.
The practical difference is that tire selection begins with trim and wheel confirmation, not just the model name. A Cadenza with replacement wheels or a previous owner modification may no longer match its original setup, so checking the current rim diameter before choosing a tire helps avoid ordering the wrong size.
What size rim does a 2019 Kia Cadenza use?
The 2019 Kia Cadenza uses either an 18-inch or 19-inch rim, depending on sub-model. The 245/45R18 tire fits the 18-inch setup, and the 245/40R19 tire fits the 19-inch setup. Both sizes are modern radial fitments with similar overall tire dimensions but different wheel diameters.
That makes rim diameter the first thing to verify on the car itself before comparing tires. Looking at the sidewall size on the existing tire and confirming the wheel diameter is especially important if the vehicle has aftermarket wheels, since the correct tire size must match the actual rim diameter in use.
Do all 2019 Kia Cadenza sub-models use the same tire size?
No, the 2019 Kia Cadenza does not use one tire size across every sub-model. Limited and Technology models use 245/40R19, while the Premium uses 245/45R18. The difference is tied to the wheel package rather than a separate tire construction type, since both sizes are radial.
That means a buyer should identify the exact trim before moving into product selection. Once the sub-model and wheel diameter are confirmed, the comparison becomes much simpler because the remaining decision is among the available tire series, brand options, and supporting specifications within the correct size.
Choosing the Right Tire
What should I consider when choosing a 245/40R19 or 245/45R18 tire for a 2019 Kia Cadenza?
Start with the correct tire size for the exact 2019 Kia Cadenza trim, since the car uses either 245/40R19 or 245/45R18. After size confirmation, compare construction, rim-width compatibility, tire series, load figures where stated, and whether the tire suits the car's intended everyday highway and street use.
The two sizes are tied to different wheel diameters, so the selection process changes once the wheel setup is known. A useful next step is comparing product specs within the correct size rather than cross-shopping between the 18-inch and 19-inch groups, because the correct fitment starts with the wheel already on the vehicle.
What sidewall styles are available for 2019 Kia Cadenza tires?
The available tire choices for the 2019 Kia Cadenza use a blackwall sidewall style. That applies across both primary sizes, 245/40R19 and 245/45R18, and across the BFGoodrich and Nitto products offered for this model. The visual presentation is modern and understated rather than restoration-oriented.
Since sidewall styling does not vary here, the real comparison shifts to tire series and supporting fitment details. Buyers choosing between available products should pay closer attention to the correct size, the wheel diameter on the car, and any differences in rim-width range or load specification that matter for the intended setup.
What brands offer tires for the 2019 Kia Cadenza?
BFGoodrich and Nitto offer tire choices for the 2019 Kia Cadenza within the applicable sizes. BFGoodrich appears in both 245/40R19 and 245/45R18 through several g-Force series, while Nitto is available in 245/45R18 with the NT555 G2. All of these are blackwall radial tires.
Brand choice should come after the correct trim-based size is locked in. Once that is settled, compare the available series within the right size and look at practical details such as rim-width range, stated load figures, and the type of driving the car sees most often rather than selecting by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Kia Cadenza?
A 2019 Kia Cadenza is a modern sedan, so a period-style presentation still begins with the correct original-format radial size for the specific trim. That means 245/40R19 for Limited and Technology models or 245/45R18 for the Premium, paired with the modern blackwall appearance used by the available products.
Appearance decisions here are more about keeping the right wheel-and-tire proportion than recreating a vintage look. Staying with the proper size and wheel diameter helps preserve the car's intended stance, and then the comparison can focus on tire series and overall presentation within the correct fitment.
Does correct tire fitment matter for a 2019 Kia Cadenza restoration or cosmetic refresh?
Yes, correct tire fitment matters because the 2019 Kia Cadenza uses two different size-and-wheel combinations across its trims. A cosmetic refresh looks more cohesive when the tire size matches the wheel diameter and the trim's intended fitment, rather than mixing an 18-inch tire size with a 19-inch wheel package or the reverse.
The visual effect of the tire depends on both sidewall proportion and how the wheel fills the opening. Confirming the current wheels, using the proper trim-based size, and checking that replacement tires suit the wheel width already on the car are the most useful steps before focusing on brand or series.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Kia Cadenza?
Yes, modifications can affect tire fitment on a 2019 Kia Cadenza, especially if the car has aftermarket wheels, altered suspension height, or changes in wheel width. Since this model uses either an 18-inch or 19-inch setup from the start, any change in wheel diameter can also change which tire size belongs on the car.
A modified vehicle should be checked for wheel diameter, wheel width, and clearance at the fender and steering range before a tire is chosen. Even when the size looks close on paper, the actual setup on the car determines whether a given tire remains a sensible fitment choice.
What should I inspect before driving a 2019 Kia Cadenza on new tires?
Before driving a 2019 Kia Cadenza on new tires, confirm that the installed size matches the trim and wheel diameter, then inspect inflation pressure, bead seating, and overall tire condition. It is also smart to look for any visible clearance issues around the inner fender, suspension, and steering components.
A short initial drive can reveal vibration, rubbing, or other setup issues that are easier to correct early. After that first road test, recheck pressure and give the tires another visual inspection, especially if the car has replacement wheels or any previous suspension changes that could affect fitment.
How often should tires on a 2019 Kia Cadenza be inspected?
Tires on a 2019 Kia Cadenza should be inspected regularly, not just when replacement time arrives. Routine checks should include tread condition, uneven wear, cuts, bulges, sidewall damage, and air loss. Since the Cadenza uses low-profile modern radial sizes, keeping an eye on condition helps catch problems before they become road-use concerns.
Monthly visual checks and pressure checks are a sensible habit, with additional inspection before longer trips. Cars that sit for extended periods still need attention, because low use does not prevent air loss or age-related condition changes, and the correct tire size does not compensate for a tire that is no longer in sound service condition.
