The 2016 Kia Optima sits in the midsize sedan segment with a sharper, more contemporary look than many family cars of its era, and its tire fitment reflects that spread from efficiency-minded trims to sportier configurations. Tire choice on this Optima centers on three primary radial sizes: 205/65R16, 215/55R17, and 235/45R18, depending on the sub-model. That means the first step is confirming the exact trim and wheel diameter before comparing tires. Available choices lean toward Blackwall performance-oriented radial lines from BFGoodrich in the 17-inch and 18-inch sizes. For everyday road use, the right decision comes down to matching the vehicle's current setup, intended driving feel, and wheel specifications.
Which Tire Size Is Right for The 2016 Kia Optima
The 2016 Kia Optima uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All three are radial fitments, but they span 16-inch, 17-inch, and 18-inch rims, so identifying the car's trim and confirming the wheels on the vehicle should come before comparing tire choices.
215/55R17 is a metric radial size in which 215 identifies the section width in millimeters, 55 is the aspect ratio, R designates radial construction, and 17 is the rim diameter in inches. On the 2016 Kia Optima, this size serves trims that step up from the base 16-inch fitment while keeping a balanced overall diameter. Available choices in this size include BFGoodrich Blackwall tires in the g-Force Comp 2 AS and g-Force Phenom T/A series. It is a useful size for owners who want to stay with the existing 17-inch wheel setup while comparing series and specification differences within the correct fitment.
205/65R16 is a metric radial size with a 205-millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 16-inch rim diameter. For the 2016 Kia Optima, this size appears on trims that use the smaller wheel package, making wheel confirmation especially important before selecting a replacement tire. Its proportions suit buyers who are maintaining the car's existing 16-inch setup rather than moving into the larger-wheel fitments used elsewhere in the range. This is the size to evaluate when the vehicle retains its original-style 16-inch wheel configuration or another confirmed 16-inch setup.
235/45R18 is a metric radial size that uses a wider 235-millimeter section width, a 45-series profile, and an 18-inch rim diameter. On the 2016 Kia Optima, this size is tied to the sport-oriented upper trims, so it should not be treated as a universal fitment across the full model line. BFGoodrich offers this size in Blackwall form across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. It is the right size to compare when the car already wears the 18-inch wheel package and the goal is to choose among compatible radial options within that configuration.
Tire fitment for the 2016 Kia Optima varies by sub-model, and some trims share a size while others move to a different wheel diameter entirely. Checking the exact trim matters here because the correct tire depends on whether the car uses a 16-inch, 17-inch, or 18-inch setup.

2016 Kia Optima EX
The 2016 Kia Optima EX uses the 215/55R17 radial fitment. That makes the tire decision less about size selection and more about choosing the right 17-inch radial based on series, wheel compatibility, and intended road use.
The 2016 Kia Optima Hybrid uses the 205/65R16 radial size. Owners should focus on maintaining the correct 16-inch wheel pairing and avoid assuming that the larger-wheel Optima tire sizes apply to this sub-model.
The 2016 Kia Optima Hybrid EX uses the 215/55R17 radial size. With the size established, the next step is comparing 17-inch tire choices that match the wheel and suit the car's intended daily-driving or touring role.
The 2016 Kia Optima LX can use either 205/65R16 or 215/55R17, so wheel diameter must be confirmed before choosing a tire. That extra verification matters because the two sizes belong to different rim packages and should not be selected by trim name alone.
The 2016 Kia Optima LX 1.6T uses the 205/65R16 radial size. Tire selection starts with keeping the correct 16-inch fitment, then comparing construction details and wheel-width compatibility for the tire being considered.
The 2016 Kia Optima SX uses the 235/45R18 radial fitment. Buyers choosing tires for this sub-model should stay focused on the 18-inch setup and compare the available Blackwall performance-oriented series within that size.
The 2016 Kia Optima SX Limited uses the 235/45R18 radial size. Since this fitment sits on the largest wheel package in the range, wheel confirmation and careful comparison of the available 18-inch tire series are the key selection steps.
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 2016 Kia Optima?
The 2016 Kia Optima uses three primary tire sizes: 205/65R16, 215/55R17, and 235/45R18. The correct size depends on the sub-model, with LX trims spanning both 16-inch and 17-inch fitments, EX and Hybrid EX using 215/55R17, Hybrid and LX 1.6T using 205/65R16, and SX and SX Limited using 235/45R18.
That means tire selection starts with confirming the exact trim and the wheels currently on the car. Two Optimas from the same model year can use different rim diameters, so checking the tire sidewall, wheel size, and vehicle setup prevents choosing a size that belongs to a different sub-model.
What size rim does a 2016 Kia Optima use?
A 2016 Kia Optima can use 16-inch, 17-inch, or 18-inch rims, depending on the sub-model and tire size. The 205/65R16 fitment uses a 16-inch rim, 215/55R17 uses a 17-inch rim, and 235/45R18 uses an 18-inch rim.
Rim diameter is the first thing to verify before comparing tires, especially on an LX because that trim can appear with either 16-inch or 17-inch fitment. The tire size must match the wheel diameter exactly, and any car with replacement wheels should be checked by the actual wheel and tire installed rather than trim name alone.
Why does the 2016 Kia Optima have more than one tire size?
The 2016 Kia Optima has more than one tire size because different sub-models use different wheel packages. The range starts at 205/65R16, steps to 215/55R17 on several trims, and moves to 235/45R18 on SX and SX Limited models.
Those size changes are tied to the vehicle's trim-specific wheel setup, not to interchangeable tire choices across the whole model line. A buyer should identify the exact sub-model and confirm the wheel diameter already on the car, since choosing by year and model alone can lead to a tire that matches another Optima configuration instead of the one being serviced.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Kia Optima?
Start with the correct size for the car's exact trim and wheel diameter, since the 2016 Kia Optima uses 205/65R16, 215/55R17, or 235/45R18 depending on configuration. Construction is straightforward because these are radial fitments, so the main comparison points become size accuracy, wheel compatibility, tire series, and any load or specification differences within the available options.
After size is confirmed, think about how the car is used and whether the existing wheels remain stock. A daily driver with 17-inch or 18-inch wheels may lead you toward different series within the same size, while any wheel change should be checked for proper width, clearance, and match to the tire being considered.
What sidewall styles are available for 2016 Kia Optima tires?
The available 17-inch and 18-inch tire choices for the 2016 Kia Optima use a Blackwall sidewall style. That keeps the appearance straightforward and modern, which suits a later-model midsize sedan without introducing vintage-style sidewall treatments.
Since sidewall variation is limited here, the real comparison shifts to tire series and fitment details rather than whitewall, stripe, or raised-letter presentation. Buyers choosing among the available products should pay closer attention to the correct tire size, wheel-width suitability, and the intended use of the car than to cosmetic sidewall differences.
What tire series are available for the 2016 Kia Optima?
The 2016 Kia Optima's available product range includes BFGoodrich tires in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, depending on size. The 215/55R17 fitment is offered in g-Force Comp 2 AS and g-Force Phenom T/A, while 235/45R18 adds g-Force Sport Comp 2 to the mix.
Series names matter because they help separate one tire choice from another even within the same size and sidewall style. Once the correct size is confirmed, compare series along with wheel-width compatibility, any stated load details, and the kind of driving the Optima sees most often rather than selecting only by brand familiarity.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Kia Optima?
A period-style approach for a 2016 Kia Optima usually means staying with the correct original-size format for the car's trim and wheel diameter rather than trying to create a vintage look. That points to 205/65R16, 215/55R17, or 235/45R18 radial tires, depending on the exact sub-model and wheel package.
Because this is a modern sedan, appearance is shaped more by maintaining the right proportions than by choosing collector-style sidewalls. A clean, correct-size Blackwall radial generally preserves the car's intended look best, while any concern about originality should start with verifying the wheel and tire size already associated with that specific trim.
Does correct tire fitment matter for a 2016 Kia Optima restoration or refresh?
Correct tire fitment matters on a 2016 Kia Optima because the model uses multiple trim-specific sizes and rim diameters. Keeping the tire matched to the proper 16-inch, 17-inch, or 18-inch setup helps preserve the car's proportions and avoids giving one trim the stance or wheel-to-tire relationship of another.
That is especially important on an LX, where both 205/65R16 and 215/55R17 appear, and on SX models that move to 235/45R18. A careful refresh should begin with the exact sub-model and actual wheels on the vehicle so the finished look stays consistent with the configuration being maintained.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Kia Optima?
Yes, modifications can affect tire fitment on a 2016 Kia Optima. Changes such as aftermarket wheels, altered wheel width, suspension lowering, or body modifications can change how a 205/65R16, 215/55R17, or 235/45R18 tire sits in the wheel opening and whether it has adequate clearance.
A car that no longer has its original wheel package should be checked by actual wheel diameter and width before replacement tires are chosen. Clearance at the fender, strut, and steering range also deserves attention, since a tire size that belongs to one Optima trim should not be assumed to suit a modified version of another.
What should I inspect before driving a 2016 Kia Optima on new tires?
Before driving a 2016 Kia Optima on new tires, inspect basic installation and condition items such as correct tire size, proper air pressure, visible bead seating, and any sign of damage or air loss. It is also worth confirming that the tires match the wheel diameter actually on the car and that the wheel hardware is properly secured.
A short check for rubbing during full steering lock and over normal suspension movement is smart, especially if the car has replacement wheels or has changed trims during its life. Looking over alignment wear patterns, suspension condition, and tread condition on the tires being replaced can also help prevent the same problem from affecting the new set.
How often should tires on a 2016 Kia Optima be inspected?
Tires on a 2016 Kia Optima should be inspected regularly, not just when replacement time arrives. Frequent visual checks for uneven wear, cracking, cuts, bulges, and pressure loss are especially useful because the model's trim-specific sizing means a mismatch or wear issue can be missed if attention stays only on the year and model.
Monthly pressure checks and routine walk-around inspections are a sensible habit, with closer attention before longer trips or seasonal changes. Cars driven less often still need monitoring, since aging and underinflation can affect a low-mileage sedan just as much as a daily driver, particularly when tire condition looks better than it actually is.
