The 2020 Kia Cadenza sits in the modern full-size sedan space with a strong emphasis on quiet highway travel, upscale road manners, and clean, understated styling. For buyers who already know this exact car, the key tire question is less about vintage-style construction and more about confirming the correct wheel setup. This Cadenza uses radial fitments in two sizes, 245/40R19 and 245/45R18, depending on sub-model and wheel diameter. Available choices lean toward blackwall performance-oriented radial lines from BFGoodrich and Nitto. The right selection comes down to matching the exact trim and rim size, then balancing everyday road use with the tire series and specifications that best suit the car.
Which Tire Size Is Right for The 2020 Kia Cadenza
Two primary tire sizes apply to the 2020 Kia Cadenza, and the first step is confirming the exact sub-model and wheel diameter. Both fitments are radial, but they use different rims: 245/40R19 for a 19-inch wheel and 245/45R18 for an 18-inch wheel. Once that is settled, the real comparison shifts to tire series, brand choice, and the rim-width specifications that match your wheel.
In 245/40R19, the 245 identifies nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. On the 2020 Kia Cadenza, this is a modern radial fitment tied to the 19-inch wheel setup rather than a vintage sizing convention. Available choices in this size include BFGoodrich lines such as g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, all in blackwall form. This size is the one to evaluate when your Cadenza is equipped with 19-inch wheels and you want to compare tire series within the correct fitment.
In 245/45R18, the 245 is the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. For the 2020 Kia Cadenza, this size belongs to the 18-inch wheel fitment and remains a fully modern radial choice. Product options include BFGoodrich g-Force series tires and the Nitto NT555 G2, all with blackwall styling and slightly different rim-width specifications. This is the size to confirm when your Cadenza has 18-inch wheels and you want to compare brand and series options within that configuration.
Sub-model fitment matters on the 2020 Kia Cadenza because tire size is not completely uniform across the range. The Limited stays with one primary size, while the Technology trim can appear with either of the two radial fitments, making wheel confirmation especially important before selecting tires.

2020 Kia Cadenza Limited
The 2020 Kia Cadenza Limited uses the 245/40R19 radial tire size. Tire selection for this trim is mainly about choosing among the available BFGoodrich blackwall performance-oriented series while confirming that the car still has its 19-inch wheel setup.
The 2020 Kia Cadenza Technology can use either 245/40R19 or 245/45R18, so this trim requires closer attention before tire selection begins. The practical decision is confirming whether the car is on 19-inch or 18-inch wheels, then comparing the product options available within that exact 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.

These 2020 Kia Cadenza tire FAQs focus on the two correct sizes, 18-inch versus 19-inch wheel fitment, available radial choices, and the practical checks to make before replacing tires on a modern luxury sedan.
Tire Size & Fitment
What tire size fits a 2020 Kia Cadenza?
The 2020 Kia Cadenza uses two tire sizes: 245/40R19 and 245/45R18. Both are radial fitments, but they do not serve the same wheel setup. The Limited uses 245/40R19, while the Technology trim can use either 245/40R19 or 245/45R18 depending on how the car is equipped.
That makes wheel confirmation the most important first step before choosing tires. A 19-inch wheel takes the 245/40R19 size, and an 18-inch wheel takes the 245/45R18 size. If the car has had wheel changes at any point, check the actual wheel diameter on the vehicle rather than relying only on trim name.
What size rim does a 2020 Kia Cadenza use?
A 2020 Kia Cadenza uses either an 18-inch or 19-inch rim, depending on tire size and configuration. The 245/45R18 fitment uses an 18-inch wheel, and the 245/40R19 fitment uses a 19-inch wheel. Both sizes are modern radial applications with closely related overall dimensions but different rim diameters.
Rim diameter has to match the tire exactly, so this is not a detail to estimate. Looking at the current tire sidewall or measuring the wheel is the quickest way to verify the setup. Once the wheel diameter is confirmed, compare the tire's approved rim-width range with the wheel on the car before making a final choice.
Do all 2020 Kia Cadenza sub-models use the same tire size?
No, tire fitment is not fully uniform across the 2020 Kia Cadenza line. The Limited uses 245/40R19, while the Technology trim can use either 245/40R19 or 245/45R18. That means the exact sub-model helps narrow the fitment, but the actual wheel diameter still needs to be confirmed on the car.
This matters because two vehicles with the same model name may not use the same tire even within the same model year. The safest approach is to identify the trim, then verify the current wheel size and tire marking. That avoids ordering an 18-inch tire for a 19-inch wheel, or the reverse.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Kia Cadenza?
Start with the correct size for the wheel on the car: 245/40R19 or 245/45R18. From there, compare radial tire series, brand, and approved rim-width range. On this Cadenza, the available choices stay within blackwall modern radial products, so the decision is more about fitment and intended road use than cosmetic variation.
A practical comparison should include the wheel diameter, wheel width, and the kind of driving the car sees most often. Some choices lean toward all-season use, while others carry a more performance-oriented character in their series naming and specifications. Matching the tire to the car's actual wheel setup remains the first priority.
What brands offer tires for the 2020 Kia Cadenza?
Tires for the 2020 Kia Cadenza are available from BFGoodrich and Nitto, depending on size. The 245/40R19 fitment is represented by BFGoodrich, while the 245/45R18 fitment includes both BFGoodrich and Nitto options. That gives the 18-inch application a broader brand spread than the 19-inch size.
Brand alone should not decide the purchase. It makes more sense to compare the correct size first, then look at tire series, rim-width compatibility, load figures where stated, and the way the car is used. On a modern sedan like the Cadenza, fitment accuracy matters more than simply choosing by brand name.
What tire series are available for the 2020 Kia Cadenza?
The 2020 Kia Cadenza is served by several radial tire series, including BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and the Nitto NT555 G2 in the 245/45R18 size. These are all blackwall modern radial offerings rather than period-style collector tires.
Series comparison is useful when the correct tire size is already confirmed and you want to sort options by character and specification. It is also worth checking each tire's approved rim-width range against the wheel on the car. That keeps the focus on proper fitment instead of choosing by series name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Kia Cadenza?
A 2020 Kia Cadenza does not call for a vintage or bias-ply look, so a period-appropriate presentation still means staying with the correct modern radial size for the car's wheel setup. That means choosing 245/40R19 or 245/45R18 as required, then selecting among the available blackwall radial series.
Appearance on this model is less about whitewalls or collector-era sidewall treatments and more about preserving the clean, contemporary stance intended for the sedan. Keeping the correct diameter, aspect ratio, and wheel match does more for visual correctness than chasing a particular brand name. Wheel changes can alter that look quickly, so verify what is on the car now.
Does correct tire fitment matter for a 2020 Kia Cadenza restoration or preservation project?
Yes, correct tire fitment still matters on a preserved or carefully maintained 2020 Kia Cadenza. Even though this is a modern sedan rather than a vintage restoration candidate, the right size preserves the car's proportions and keeps the wheel-and-tire package in line with its intended setup. On this model, that means using the proper 18-inch or 19-inch fitment.
For owners focused on original presentation, the most important visual step is maintaining the correct size and wheel diameter rather than experimenting with alternate profiles. Tire choice can then be narrowed by blackwall radial series and brand. Any car with replacement wheels should be checked carefully so the final fitment still suits the body and suspension layout.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Kia Cadenza?
Yes, modifications can affect tire fitment on a 2020 Kia Cadenza even when the tire size appears close to stock. Wheel changes, altered offset, suspension lowering, or body modifications can influence clearance at the fender, steering components, and inner wheelhouse. That is especially important here because the car already uses two different wheel diameters depending on configuration.
A modified Cadenza should be checked at full steering lock and through normal suspension travel before settling on a replacement tire. The best starting point is still the correct size for the wheel in use, followed by confirmation that the wheel width suits the tire. Small setup changes can have a larger fitment effect than the size code alone suggests.
What should I inspect before driving a 2020 Kia Cadenza on new tires?
Before driving a 2020 Kia Cadenza on new tires, confirm that the installed size matches the wheel, the tire pressure is set correctly for the application, and the beads are seated properly. It also helps to inspect for any visible wheel damage, uneven suspension wear, or alignment issues that could shorten tire life from the start.
A short road check should include listening for rubbing, vibration, or pull that was not present before the tire change. Rechecking pressure after the first drives is also smart, especially if the car has been sitting or the wheels were recently serviced. Any unusual contact or air loss deserves attention before regular use continues.
How often should tires on a 2020 Kia Cadenza be inspected?
Tires on a 2020 Kia Cadenza should be inspected regularly, not just when tread looks low. A routine walkaround can catch cuts, punctures, sidewall bulges, irregular wear, or air loss early. On a car that sees mixed daily and highway use, checking condition and pressure monthly is a sensible habit, with a closer inspection before longer trips.
Inspection matters even more if the sedan is driven infrequently, because age and storage conditions can affect tires long before they wear out. Looking at the inner and outer shoulder wear pattern can also reveal alignment or suspension issues. Keeping the correct pressure and addressing damage early helps preserve ride quality and stability.
