The 2009 Kia Optima sits in the practical midsize sedan class, offering a straightforward blend of everyday comfort, tidy proportions, and trim-dependent wheel and tire choices. For buyers replacing tires on one today, the main fitment question is less about vintage-style construction and more about matching the car’s exact wheel setup. This model uses radial tires in either 205/60R16 or 215/50R17, depending on sub-model and wheel package. Available choices range from a distinctive wide whitewall radial in 205/60R16 to blackwall performance-oriented 215/50R17 options. Before choosing, it helps to confirm the sub-model and wheel diameter, then decide whether appearance or modern driving character matters most.
Which Tire Size Is Right for The 2009 Kia Optima
The 2009 Kia Optima uses two primary tire sizes, and the right one depends on the sub-model and wheel diameter. Both are radial fitments, but one is built around a 16-inch rim and the other around a 17-inch rim. Before selecting a tire, confirm whether the car is set up for the 205/60R16 or the 215/50R17 size, since that wheel diameter difference is the first fitment checkpoint.
A 205/60R16 tire uses a 205-millimeter section width, a 60-series aspect ratio, radial construction, and a 16-inch rim. On the 2009 Kia Optima, this size suits the 16-inch wheel setup and is the primary fitment for the LX, while also appearing on some EX and EX V6 applications. Available choices include an American Classic radial with a 1.50 inch wide whitewall and an asymmetrical tread design. This size is the one to evaluate if the car wears 16-inch wheels and the goal is either a standard radial replacement or a more distinctive appearance.
A 215/50R17 tire is slightly wider in section width than the 205 size, uses a 50-series profile, radial construction, and mounts on a 17-inch rim. On the 2009 Kia Optima, it belongs to the 17-inch wheel configuration used on the SX and SX V6, and it can also apply to EX and EX V6 versions. Current choices in this size center on BFGoodrich blackwall performance-oriented series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This is the size to compare when the car already has 17-inch wheels and a sportier tire presentation is the priority.
Sub-model fitment matters on the 2009 Kia Optima because some trims use one size exclusively while others can be found with either 16-inch or 17-inch wheel setups. Confirming the exact trim and the wheel diameter on the car is the clearest way to narrow the tire choice before comparing brands, sidewall styles, or tire series.

2009 Kia Optima EX
The 2009 Kia Optima EX can use either the 205/60R16 or 215/50R17 radial size, so wheel diameter should be confirmed before ordering. That makes the EX a trim where the real tire decision starts with the wheel on the car, then moves to appearance and driving character.
The 2009 Kia Optima EX V6 also appears with either 205/60R16 or 215/50R17 radials, depending on its wheel setup. For this sub-model, checking the actual rim diameter avoids mixing 16-inch and 17-inch fitments and helps narrow the choice between whitewall and blackwall-style options.
The 2009 Kia Optima LX uses the 205/60R16 radial size on its 16-inch setup. Tire selection here is more straightforward, with the focus shifting from fitment confusion to choosing the right look and rim-width compatibility within that size.
The 2009 Kia Optima SX uses the 215/50R17 radial size on a 17-inch rim. That points the buyer toward blackwall performance-oriented options and makes wheel confirmation simpler, since this sub-model does not share the smaller 16-inch primary fitment.
The 2009 Kia Optima SX V6 uses the 215/50R17 radial tire size. For this sub-model, the main comparison is among available 17-inch radial choices, with attention to tire series, rim-width range, and the overall character desired from the replacement tire.
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 2009 Kia Optima?
The 2009 Kia Optima uses either 205/60R16 or 215/50R17, depending on the sub-model and wheel setup. Both are radial sizes, but they are not interchangeable as primary fitments because one is built for a 16-inch rim and the other is built for a 17-inch rim.
The first step is confirming the wheel diameter actually on the car. LX models use 205/60R16, SX and SX V6 models use 215/50R17, and EX or EX V6 cars can appear with either size. Once the wheel size is confirmed, compare the available tires by sidewall style, rim-width range, and overall tire character.
What size rim does a 2009 Kia Optima use?
A 2009 Kia Optima uses either a 16-inch or 17-inch rim, depending on trim and wheel package. The 205/60R16 tire matches the 16-inch rim setup, while the 215/50R17 tire matches the 17-inch rim setup used on other versions of the car.
Checking the actual rim diameter is important before ordering tires, especially on EX and EX V6 models that can use either fitment. Looking at the existing tire size on the sidewall and confirming the wheel itself helps prevent a mismatch between a 16-inch tire and a 17-inch wheel or the reverse.
Why does the 2009 Kia Optima have more than one tire size?
The 2009 Kia Optima has more than one tire size because different sub-models and wheel packages use different rim diameters. Some trims are tied to a single fitment, while EX and EX V6 versions can be found with either the 16-inch 205/60R16 setup or the 17-inch 215/50R17 setup.
That means trim name alone may not always settle the question if the car has one of the flexible EX-based applications. A quick check of the tire sidewall or wheel diameter is the safest starting point. After that, the decision becomes which radial tire best matches the car’s look and driving use.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 Kia Optima?
Start with the correct primary size: 205/60R16 for the 16-inch setup or 215/50R17 for the 17-inch setup. From there, compare the tire’s rim-width range, radial construction, sidewall style, tire series, and any load information that matters to how the car is used.
The 205/60R16 choices lean toward appearance with a wide whitewall option, while the 215/50R17 choices lean toward blackwall performance-oriented series. That makes the right selection less about finding a universal answer and more about matching the tire to the wheel on the car and the presentation you want.
What sidewall styles are available for 2009 Kia Optima tires?
Sidewall style depends on the size being used. In 205/60R16, the available option uses a wide whitewall treatment. In 215/50R17, the available choices are blackwall tires, giving the larger-wheel setup a more modern and performance-oriented visual character.
That difference makes sidewall style part of the buying decision, not just a cosmetic detail. A whitewall can change the entire look of an Optima fitted with 16-inch wheels, while the 17-inch tires keep a cleaner blackwall appearance. Confirm the size first, then choose the sidewall presentation that suits the car.
What tire series are available for the 2009 Kia Optima?
The 2009 Kia Optima has several distinct tire series across its two sizes. The 205/60R16 option uses an American Classic asymmetrical tread radial, while the 215/50R17 options include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A.
Series names help separate the available tires by character, but the first filter is still the correct wheel and tire size. Once that is settled, compare details such as rim-width compatibility, sidewall treatment, load figures where stated, and whether the goal is a more distinctive look or a more modern blackwall presentation.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Kia Optima?
A period-style choice for a 2009 Kia Optima starts with keeping the correct tire size for the wheel on the car, then selecting a tire that supports the appearance you want. Among the available options, the 205/60R16 American Classic radial stands out because it uses a 1.50 inch wide whitewall.
That does not make it a universal answer for every Optima, since the car may instead require the 17-inch 215/50R17 fitment. Buyers focused on presentation should confirm wheel diameter first, then decide whether a wide whitewall look or a blackwall performance-style look better matches the car’s intended finished appearance.
How does tire construction affect the appearance of a restored 2009 Kia Optima?
On the 2009 Kia Optima, construction is less of an appearance dividing line than it is on older collector cars because the primary fitments here are radial tires. The more visible styling difference comes from sidewall treatment and tire series, especially the contrast between the whitewall 205/60R16 option and the blackwall 215/50R17 choices.
For a restoration-oriented or appearance-conscious owner, the key is staying with the correct size and wheel diameter before focusing on the visual details. A whitewall can create a very different finished look from a blackwall, even when both are radials, so the tire should support the car’s intended presentation rather than fight it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Kia Optima?
Yes, modifications can affect tire fitment on a 2009 Kia Optima. Aftermarket wheels, suspension changes, lowering, or body alterations can change the relationship between the tire, rim width, and available clearance, even when the tire size appears close to one of the original 16-inch or 17-inch fitments.
A modified car should be checked for actual wheel diameter, wheel width, and clearance at the fender and steering components before replacement tires are chosen. That matters most on EX and EX V6 cars, where either primary size may appear, and on any car where the existing setup may no longer match stock trim-based expectations.
What should I inspect before driving a 2009 Kia Optima on new tires?
Before driving a 2009 Kia Optima on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure inflation is set appropriately for the tire being used. It also helps to check for uneven wear patterns that could point to alignment or suspension issues.
A short road check after installation is worthwhile to confirm there is no rubbing, vibration, or pull. Collector vehicles are not the only ones that suffer from age-related issues, so sidewall condition on the old tires, valve stem condition, and any signs of air loss are all worth reviewing before putting the car back into regular use.
How often should tires on a 2009 Kia Optima be inspected?
Tires on a 2009 Kia Optima should be inspected regularly, not just when tread looks worn. A visual check for cracking, cuts, bulges, uneven wear, and low inflation can catch problems early, whether the car uses the 205/60R16 setup or the 215/50R17 setup.
Cars that sit for longer periods deserve extra attention because age and storage conditions can affect tire condition even with limited mileage. Looking over the tires before longer drives and during routine maintenance visits helps confirm that the Optima’s tires remain suitable for road use and still match the wheel setup on the car.
