The 2014 Kia Optima sits in the midsize sedan segment with a distinctly modern shape and a stronger design identity than many family cars of its era. Buyers looking at one today are often balancing everyday drivability with the need to match the car’s exact trim-level wheel package. Tire fitment on the 2014 Kia Optima is entirely radial, but it is not one-size-fits-all, with 16-inch, 17-inch, and 18-inch applications depending on sub-model. That makes the real choice less about vintage-style construction and more about confirming the correct trim, wheel diameter, and the type of road-going tire character you want.
Which Tire Size Is Right for The 2014 Kia Optima
The 2014 Kia Optima uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All three are metric radial sizes, but they are spread across 16-inch, 17-inch, and 18-inch rims, so the first step is confirming which wheels are on the car now. Once that is settled, the decision shifts to selecting the right tire series and product characteristics within the correct size.
A 215/55R17 tire is a metric radial size with a 215 millimeter section width, a 55-series aspect ratio, and fitment for a 17-inch rim. On the 2014 Kia Optima, this size suits certain trims that use a balanced middle-ground wheel package rather than the smaller 16-inch or larger 18-inch setup. Available choices center on BFGoodrich offerings in blackwall construction, including g-Force Comp 2 AS and g-Force Phenom T/A series. This size is the right one to evaluate when the car already wears 17-inch wheels and you want to compare tire character without moving away from the intended wheel diameter.
A 205/65R16 tire is a metric radial size that uses a 205 millimeter section width, a 65-series profile, and a 16-inch rim. On the 2014 Kia Optima, this size belongs to trims that use the smaller wheel package, so it should not be confused with the 17-inch or 18-inch fitments found elsewhere in the lineup. Its sizing emphasizes correct wheel match first, since the diameter and profile are different from the other Optima applications. This is the size to confirm when maintaining stock-style fitment on a 16-inch-wheel car or when checking a Hybrid LX that may have been equipped either way.
A 225/45R18 tire is a metric radial with a 225 millimeter section width, a 45-series aspect ratio, and fitment for an 18-inch rim. On the 2014 Kia Optima, this size is tied to trims using the larger wheel package, making wheel confirmation especially important before comparing products. Available options include blackwall tires from BFGoodrich and Nitto across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is the one to review when the car carries 18-inch wheels and the goal is to compare series, load-related specifications, and tire character within the correct fitment.
Tire fitment on the 2014 Kia Optima changes by sub-model, and in one case it can vary within the same trim family. Checking the exact badge and wheel diameter matters before choosing a tire, because the Optima range spans 16-inch, 17-inch, and 18-inch applications.

2014 Kia Optima EX
The 2014 Kia Optima EX uses the 215/55R17 radial size. That keeps selection focused on confirming the existing 17-inch wheel setup and then comparing available blackwall tire series within that size.
The 2014 Kia Optima Hybrid EX also uses the 215/55R17 radial size. Tire selection follows the same path as the EX, with the main task being proper 17-inch wheel confirmation and choosing among the available radial product lines.
The 2014 Kia Optima Hybrid LX can use either 205/65R16 or 215/55R17, so this is the trim where wheel verification comes first. Before choosing a tire, check whether the car is on the 16-inch or 17-inch setup so the replacement size matches the actual wheel package.
The 2014 Kia Optima LX uses the 205/65R16 radial size. That makes the key decision straightforward: confirm that the car still has its 16-inch wheels and choose a tire that stays within that fitment.
The 2014 Kia Optima Limited uses the 225/45R18 radial size. Tire choice here centers on the larger 18-inch wheel package, where comparing series, brand options, and product specifications becomes more important than sorting through multiple primary sizes.
The 2014 Kia Optima SX uses the 225/45R18 radial size. That points the buying decision toward matching the 18-inch wheel diameter first, then reviewing the available performance-oriented radial choices in that size.
The 2014 Kia Optima SX Turbo uses the 225/45R18 radial size. With the correct 18-inch wheel setup confirmed, the remaining decision is which blackwall radial series best suits the car’s current use and 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.

Tire Size & Fitment
What tire size fits a 2014 Kia Optima?
A 2014 Kia Optima can use three different tire sizes: 205/65R16, 215/55R17, and 225/45R18. The correct size depends on the exact sub-model and wheel package, with LX models using 205/65R16, EX and Hybrid EX using 215/55R17, and Limited, SX, and SX Turbo using 225/45R18. Hybrid LX models can use either 205/65R16 or 215/55R17.
The most important next step is checking the car’s actual wheel diameter before ordering tires. A 16-inch tire will not work on a 17-inch or 18-inch rim, and vice versa. If the Optima has had wheel changes at some point, use the wheel itself rather than the trim badge alone as the final confirmation.
What size rim does a 2014 Kia Optima use?
The 2014 Kia Optima uses three rim diameters across its model range: 16-inch, 17-inch, and 18-inch. Those wheel sizes correspond to the three primary tire sizes used on the car, so rim diameter is directly tied to proper tire selection rather than being a secondary detail.
Checking rim diameter first prevents the most basic fitment mistake. Once that is confirmed, it also helps narrow the correct trim-level tire size quickly, especially on a Hybrid LX where two different wheel and tire combinations are possible. If aftermarket wheels are installed, also verify wheel width before comparing specific tire models.
Why does the 2014 Kia Optima have more than one tire size?
The 2014 Kia Optima has more than one tire size because different sub-models use different wheel packages. The lineup spans 205/65R16 on 16-inch rims, 215/55R17 on 17-inch rims, and 225/45R18 on 18-inch rims, with the Hybrid LX appearing in either the 16-inch or 17-inch setup.
That means the right tire is determined by the exact trim and the wheels currently on the car. It is not enough to match the year and model name alone. A quick check of the existing sidewall size or wheel diameter will usually settle the question and keep the replacement aligned with the car’s actual configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Kia Optima?
Start with the correct size for the exact sub-model and wheel diameter, since the 2014 Kia Optima uses 16-inch, 17-inch, and 18-inch applications. After that, compare construction details within the proper size, including wheel-width compatibility, load-related specifications where stated, and the intended character of the tire series.
The available Optima products are all radial blackwall tires, so the decision is mainly about matching the car’s setup and use rather than choosing between vintage constructions or sidewall styles. A daily-driven EX may call for a different product emphasis than an SX on 18-inch wheels, even when both choices stay fully within correct fitment.
What brands offer tires for the 2014 Kia Optima?
BFGoodrich and Nitto both offer tires for the 2014 Kia Optima within the sizes available here. BFGoodrich appears in 215/55R17 and 225/45R18, while Nitto is offered in 225/45R18. That gives buyers some brand choice, especially on the 18-inch applications used by Limited, SX, and SX Turbo models.
Brand alone should not decide the purchase. It makes more sense to compare the exact size, the tire series, and the wheel-width range that matches the car’s rims. On a 17-inch Optima, the comparison is within BFGoodrich series, while the 18-inch fitment opens the door to a broader brand and series comparison.
What tire series are available for the 2014 Kia Optima?
Available tire series for the 2014 Kia Optima include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, BFGoodrich g-Force Sport Comp 2, and Nitto NT555 G2. These series appear across the 17-inch and 18-inch Optima applications, with the broader selection concentrated in 225/45R18.
Series names matter because they help distinguish the kinds of product choices available within the same size. Once the correct tire size is confirmed, comparing series can help narrow the field by wheel-width compatibility, weight, and other stated product characteristics. That is especially useful on 18-inch Optimas, where several product lines are available in the same fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Kia Optima?
A period-style approach on a 2014 Kia Optima usually means staying with the tire size that matches the car’s original wheel package rather than changing diameter or profile. Since this Optima uses modern radial sizes, the closest visual match comes from retaining the correct 16-inch, 17-inch, or 18-inch fitment for the exact trim.
Appearance is more consistent when the sidewall height and wheel relationship remain in proportion to the car’s intended setup. Because the available products here are blackwall radials, the deciding factor is less about decorative sidewall treatment and more about preserving the overall stance and size relationship that suits the specific Optima sub-model.
Does correct tire fitment matter for a 2014 Kia Optima restoration?
Correct tire fitment matters on a 2014 Kia Optima restoration because wheel diameter and tire profile strongly affect how the car sits and presents visually. Using 205/65R16, 215/55R17, or 225/45R18 in the wrong place can change the look of the car even before any driving considerations enter the picture.
For a restoration-minded owner, the safest starting point is the exact size tied to the car’s trim and wheel package. That keeps the proportions aligned with the way the Optima was configured in period. If the car has been modified, confirming the actual wheels on the vehicle is still more important than assuming fitment from the model badge.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Kia Optima?
Yes, modifications can affect tire fitment on a 2014 Kia Optima. Aftermarket wheels, suspension changes, lowering, and body alterations can all change the space available for the tire, even when the tire size matches one of the known Optima applications such as 205/65R16, 215/55R17, or 225/45R18.
A modified Optima should be checked for wheel diameter, wheel width, and clearance at full steering lock and through suspension travel before replacing tires. Changes in rim size or offset are especially important, because a tire that is correct for one stock trim can still be the wrong choice for a car with a different wheel setup.
What should I inspect before driving a 2014 Kia Optima on new tires?
Before driving a 2014 Kia Optima on new tires, inspect wheel condition, confirm the tire size matches the actual rim diameter, and make sure inflation is set correctly for the application. It also helps to look over the suspension and alignment condition, since uneven wear patterns or steering pull can shorten tire life quickly.
A short test drive should include listening for rubbing and checking that the car tracks normally. Recheck pressure after installation and keep an eye on any vibration that was not present before. On an Optima with non-stock wheels, a final clearance check is worthwhile even when the tire size itself appears correct.
How should tires on a 2014 Kia Optima be maintained?
Tires on a 2014 Kia Optima should be maintained with regular pressure checks, routine visual inspections, and attention to tread wear across the full width of the tire. Watch for cracking, cuts, bulges, or repeated air loss, and do not ignore feathering or shoulder wear that may point to alignment or suspension issues.
Consistent maintenance matters because the Optima uses several different wheel-and-tire combinations, and each depends on staying within the correct size and operating condition. Vehicles that sit for long periods still need inspection, since age and storage conditions can affect tire health even when mileage stays low. Clean, dry storage away from heat and ozone sources is helpful.
