The 2017 Kia Cadenza sits in the full-size sedan category with a quieter, upscale character than many mainstream family cars, so tire choice plays a real role in preserving the car’s composed road manners and clean appearance. On this model, fitment centers on two radial sizes: 245/45R18 and 245/40R19, depending on trim and wheel package. That means the first step is confirming which sub-model and rim diameter the car actually has before comparing tires. From there, the decision is less about vintage-style construction and more about choosing the right blackwall radial by size, series, and intended driving use.
Which Tire Size Is Right for The 2017 Kia Cadenza
Two tire sizes apply to the 2017 Kia Cadenza, and the difference comes down to sub-model and wheel diameter. Some versions use 245/45R18 on an 18-inch rim, while others use 245/40R19 on a 19-inch rim, so confirming the exact trim and wheel setup is the first step before comparing tire choices.
245/40R19 is a metric radial size: 245 identifies the nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. On the 2017 Kia Cadenza, this size belongs with the 19-inch wheel setup rather than the 18-inch configuration. Available choices are blackwall radials from BFGoodrich across g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A lines. This size is the one to evaluate when the car already wears 19-inch wheels and you want to compare series and use type within that fitment.
245/45R18 is also a metric radial size, with a 245-millimeter nominal width, a 45-series aspect ratio, and an 18-inch rim diameter. For the 2017 Kia Cadenza, this size is tied to the 18-inch wheel fitment, so wheel diameter should be confirmed before anything else. Product choices include blackwall radials from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the relevant size for Cadenzas equipped with the 18-inch setup and gives the buyer several modern radial options to compare.
Sub-model fitment matters on the 2017 Kia Cadenza because tire size changes with trim and wheel package. The right starting point is identifying whether the car is a Limited, Premium, or Technology model and then confirming whether it carries 18-inch or 19-inch wheels.

2017 Kia Cadenza Limited
The 2017 Kia Cadenza Limited uses the 245/40R19 radial fitment on a 19-inch wheel setup. That makes wheel-diameter confirmation especially important before comparing blackwall radial choices across the available performance-oriented tire series.
The 2017 Kia Cadenza Premium uses the 245/45R18 radial size with the 18-inch wheel configuration. Tire selection here focuses on staying with the correct 18-inch fitment and then comparing brand, tire series, and rim-width suitability.
The 2017 Kia Cadenza Technology appears with either 245/40R19 or 245/45R18 radial tires, so this trim requires an extra wheel check before selecting a replacement. The practical decision is not the trim name alone, but whether the car currently has the 18-inch or 19-inch setup.
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.
Best 2017 Kia Cadenza Tires for Sale
Available 2017 Kia Cadenza tires center on blackwall radials in 245/40R19 and 245/45R18. BFGoodrich covers both sizes with several g-Force series, while 245/45R18 also adds a Nitto NT555 G2 option, giving buyers useful variety in series and rim-width compatibility.
These 2017 Kia Cadenza tire FAQs focus on the two correct sizes, trim-related fitment differences, wheel diameter, available brands and series, and the checks worth making before putting the car back into regular road use.
Tire Size & Fitment
What tire size fits a 2017 Kia Cadenza?
The 2017 Kia Cadenza uses two radial tire sizes: 245/45R18 and 245/40R19. The correct size depends on the sub-model and wheel package, with Premium using 245/45R18, Limited using 245/40R19, and Technology appearing with either size depending on the wheel setup.
That means the first step is checking the actual rim diameter on the car before choosing a tire. Even though the two sizes are very close in overall diameter, they are built for different wheel diameters, so an 18-inch tire cannot be used on a 19-inch wheel, and vice versa.
What size rim does a 2017 Kia Cadenza use?
A 2017 Kia Cadenza uses either an 18-inch or 19-inch rim, depending on the trim and wheel package. The 245/45R18 tire pairs with an 18-inch wheel, while the 245/40R19 tire pairs with a 19-inch wheel.
Rim diameter is the most important fitment check because it immediately determines which tire size group applies. Once that is confirmed, it also helps narrow the product choices by proper rim-width range, since the 18-inch and 19-inch options carry different wheel-width specifications across the available tires.
Why does the 2017 Kia Cadenza have more than one tire size?
The 2017 Kia Cadenza has more than one tire size because different sub-models and wheel packages use different rim diameters. Premium models use 245/45R18, Limited models use 245/40R19, and Technology models can appear with either fitment.
This is why trim alone should not be the only guide if the car has had wheel changes or if you are looking at a Technology model. A quick check of the actual wheel diameter and the current tire sidewall marking helps prevent ordering the right width and profile in the wrong rim size.
Choosing the Right Tire
What should I consider when choosing a 2017 Kia Cadenza tire?
Start with the correct size for the car’s wheel package: 245/45R18 for the 18-inch setup or 245/40R19 for the 19-inch setup. After size is settled, compare construction, rim-width range, load capacity where stated, tire series, and the kind of driving the car actually sees.
The available Cadenza options are all blackwall radials, but they vary by series and wheel-width compatibility. That makes it worth checking the actual wheel width before choosing, especially if the sedan has aftermarket wheels or if you want a tire that matches the car’s balance of daily comfort and more responsive handling.
What sidewall styles are available for 2017 Kia Cadenza tires?
The available 2017 Kia Cadenza tires in these fitments use a blackwall sidewall style. That applies across the listed 245/40R19 and 245/45R18 product choices, including the BFGoodrich and Nitto options offered in these sizes.
For a modern sedan like the Cadenza, blackwall keeps the presentation clean and straightforward, so the real differences come from size, tire series, and wheel compatibility rather than decorative sidewall treatment. Once the correct size is confirmed, the buyer can focus on the tire’s character instead of appearance variations.
What brands offer tires for the 2017 Kia Cadenza?
BFGoodrich and Nitto offer tires for the 2017 Kia Cadenza within these fitments. BFGoodrich appears in both 245/40R19 and 245/45R18, while Nitto is available in the 245/45R18 size through the NT555 G2 line.
Brand comparison should come after confirming the correct wheel diameter and tire size on the car. In practice, the more useful comparison is often between the tire series within the correct size, since those differences affect which products make the most sense for the car’s wheels and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Kia Cadenza?
A period-style approach for a 2017 Kia Cadenza starts with preserving the correct factory-era size relationship for the wheel package already on the car. That means staying with 245/45R18 on 18-inch wheels or 245/40R19 on 19-inch wheels and choosing a blackwall radial that suits the car’s original modern-sedan presentation.
Because this is a late-model full-size sedan rather than a vintage collector car, appearance choices are more about maintaining the proper stance and sidewall profile than selecting whitewalls or specialty vintage styling. Keeping the right size and wheel pairing usually matters more to the overall look than choosing between brands.
Does correct tire fitment matter for a 2017 Kia Cadenza restoration or clean original-style presentation?
Yes, correct tire fitment matters because the 2017 Kia Cadenza was designed around two specific modern radial sizes tied to two different wheel diameters. Using the proper 245/45R18 or 245/40R19 size helps preserve the car’s intended proportions and avoids the mismatched look that can come from an incorrect profile or wheel pairing.
A clean original-style presentation usually comes from getting the basics right: correct size, correct rim diameter, and an appropriate blackwall radial. If the car has replacement wheels, confirm their diameter and width carefully, since a wheel change can alter both the appearance and the tire choices that make sense.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Kia Cadenza?
Yes, modifications can affect tire fitment on a 2017 Kia Cadenza. Aftermarket wheels, altered wheel width, offset changes, suspension lowering, or body modifications can all change which 245-section tire works properly, even when the sidewall size marking looks close to the original setup.
That is especially important on the Technology trim, where either 18-inch or 19-inch fitment may appear. Check the actual wheel diameter and width first, then look for steering and fender clearance through a full turn and normal suspension movement before settling on a replacement tire.
What should I inspect before driving a 2017 Kia Cadenza on new tires?
Before driving a 2017 Kia Cadenza on new tires, inspect wheel diameter, wheel width, and overall tire size against the car’s trim and current wheel package. It also makes sense to check valve stems, wheel condition, lug hardware, and the initial air pressure so the new tires start from a sound baseline.
A short follow-up inspection after the first miles is also worthwhile. Look for any rubbing at full steering lock, uneven seating on the wheel, vibration, or unexpected air loss, since these signs can point to a wheel mismatch, clearance issue, or installation problem that should be corrected early.
How often should tires on a 2017 Kia Cadenza be inspected?
Tires on a 2017 Kia Cadenza should be inspected regularly, not just when tread looks worn. Pressure, tread wear, cuts, bulges, and sidewall condition are all worth checking on a routine basis, especially if the car spends long periods parked or sees changing seasonal temperatures.
Frequent inspection helps catch problems before they affect ride quality or road manners. It is also a practical way to spot alignment issues, suspension wear, or slow air loss early, which matters on a sedan using lower-profile 245-section radials where changes in pressure and wear pattern can become noticeable quickly.
