The 2013 Kia Optima sits in the midsize sedan segment with a design language that helped give this generation a more athletic, upscale presence than many family cars of its era. That matters when choosing tires, because the Optima’s wheel and tire package changes noticeably across trim levels. This model uses three primary radial sizes: 205/65R16, 215/55R17, and 225/45R18, depending on sub-model. Available choices lean toward modern blackwall radial designs from BFGoodrich and Nitto, with differences in tire series, rim-width compatibility, and load specification. The key is matching the exact trim and wheel diameter first, then selecting the tire character that suits everyday driving, appearance, and any existing wheel changes.
Which Tire Size Is Right for The 2013 Kia Optima
The 2013 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 are split across 16-inch, 17-inch, and 18-inch rims. Before choosing a tire, confirm the trim and the actual wheel diameter on the car, especially if the vehicle has changed hands or has been updated with different wheels.
215/55R17 is a metric radial size in which 215 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2013 Kia Optima, this size suits trims that use a 17-inch wheel and keeps the tire choice in a modern radial format. Available options in this size come from BFGoodrich in blackwall form, including the g-Force Comp 2 AS and g-Force Phenom T/A series. It is the right size to evaluate when the car has a 17-inch setup and the goal is balancing correct fitment with the desired tire character.
205/65R16 is a metric radial size where 205 indicates nominal section width in millimeters, 65 is the aspect ratio, R stands for radial construction, and 16 identifies the wheel diameter in inches. For the 2013 Kia Optima, this size is tied to sub-models that use a 16-inch wheel and represents the most conservative of the three primary fitments. Its slightly taller profile shape is part of what distinguishes it from the larger-wheel options used elsewhere in the range. Choose this size only after confirming the car still wears the correct 16-inch wheel package for that trim.
225/45R18 is a metric radial size with a 225-millimeter nominal section width, a 45-series profile, radial construction, and an 18-inch rim diameter. On the 2013 Kia Optima, this size is associated with trims using the largest wheel package in the lineup, so wheel diameter confirmation is especially important. Product choices in this size include blackwall radial options from BFGoodrich and Nitto across several performance-oriented series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the size to consider when the car has factory-style 18-inch fitment or an unchanged equivalent wheel setup.
Tire fitment on the 2013 Kia Optima varies by sub-model, so trim identification matters before selecting a replacement tire. Most sub-models use one primary size, while the Hybrid LX can be found with either a 16-inch or 17-inch fitment.

2013 Kia Optima EX
The 2013 Kia Optima EX uses the 215/55R17 radial size on a 17-inch wheel package. Tire selection here is mainly about choosing the right blackwall radial option within that size and confirming the wheel has not been changed from the original diameter.
The 2013 Kia Optima Hybrid EX also uses the 215/55R17 radial size. That keeps the decision focused on product choice within the correct 17-inch fitment rather than sorting through multiple primary sizes.
The 2013 Kia Optima Hybrid LX can use either 205/65R16 or 215/55R17, making wheel confirmation the first step before replacing tires. Once the actual rim diameter is verified, the tire choice becomes much more straightforward.
The 2013 Kia Optima LX uses the 205/65R16 radial size. That means replacement starts with a 16-inch wheel fitment check, especially on cars that may have been upgraded with larger aftermarket wheels.
The 2013 Kia Optima SX uses the 225/45R18 radial size on an 18-inch wheel. Choosing tires for this sub-model centers on staying with the proper lower-profile fitment and comparing the available blackwall radial series in that size.
The 2013 Kia Optima SXL uses the 225/45R18 radial size. That makes wheel diameter and rim-width compatibility important checkpoints before comparing the available 18-inch blackwall radial options.
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 FAQs focus on 2013 Kia Optima tire sizes, trim-level fitment, wheel diameter, product selection, and the basic checks that matter before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2013 Kia Optima?
A 2013 Kia Optima can use 205/65R16, 215/55R17, or 225/45R18, depending on the exact sub-model. LX uses 205/65R16, EX and Hybrid EX use 215/55R17, and SX and SXL use 225/45R18. Hybrid LX is the exception because it appears with either 205/65R16 or 215/55R17.
The practical step is to confirm the trim and the wheel diameter actually on the car before ordering tires. Many Optimas have changed hands, and some may have aftermarket wheels or a different OE-style wheel package. The correct size starts with the rim diameter, then moves to matching the exact tire specification for that setup.
What size rim does a 2013 Kia Optima use?
The 2013 Kia Optima uses 16-inch, 17-inch, or 18-inch rims, depending on sub-model and tire size. The 205/65R16 fitment uses a 16-inch rim, 215/55R17 uses a 17-inch rim, and 225/45R18 uses an 18-inch rim.
Rim diameter is the first thing to verify because the tire size must match it exactly. A 16-inch tire cannot be mounted on a 17-inch wheel, and an 18-inch tire cannot be used on a 17-inch rim. Checking the wheel first prevents choosing the right tire size for the wrong wheel package.
Why does the 2013 Kia Optima have more than one tire size?
The 2013 Kia Optima has more than one tire size because tire fitment changes across the model range. Different trims use different wheel diameters, which leads to 205/65R16, 215/55R17, or 225/45R18 as the primary sizes. The Hybrid LX spans two fitments, so it needs extra attention.
That variation means there is no single universal tire size for every 2013 Optima. The right choice depends on the exact sub-model and the wheel currently installed on the vehicle. Looking at the existing sidewall marking and confirming the trim level is the simplest way to narrow the choice before comparing tire options.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Kia Optima?
Start with the correct primary size for the specific 2013 Kia Optima sub-model, then compare the tire’s construction, rim-width specification, and any stated load details. This vehicle uses radial tires only, so the main decision is not bias-ply versus radial, but choosing the right modern radial within the proper 16-inch, 17-inch, or 18-inch fitment.
Once size is settled, look at how the car is actually used. Daily driving, wheel changes, and personal preference for a more touring-oriented or sportier tire series can all shape the final choice. A tire that matches the wheel diameter and width range is far more important than choosing by appearance or brand alone.
What sidewall styles are available for 2013 Kia Optima tires?
The available 2013 Kia Optima products here use a blackwall sidewall style. That applies across the visible 17-inch and 18-inch tire selections, including BFGoodrich and Nitto options. The emphasis is on modern radial blackwall presentation rather than whitewall, stripe, or raised-letter vintage treatments.
For most buyers, that keeps the appearance decision simple and shifts attention to size, series, and wheel compatibility. If the car has been modified for a different visual theme, the first step is still confirming the correct tire size and wheel package. Sidewall style should follow fitment, not override it.
What brands offer tires for the 2013 Kia Optima?
BFGoodrich and Nitto offer tire options for the 2013 Kia Optima among the available sizes shown here. BFGoodrich appears in both 17-inch and 18-inch fitments, while Nitto is present in the 225/45R18 size. The available series vary by size rather than every brand appearing in every fitment.
That means the best way to compare brands is after the correct tire size is confirmed. Once the right wheel diameter is established, the remaining differences come down to tire series, rim-width range, and related specifications. Brand choice matters, but only within the correct fitment for the specific Optima trim.
Restoration & Appearance
How does tire construction affect the appearance of a 2013 Kia Optima?
On a 2013 Kia Optima, tire construction is straightforward because the primary fitments are radial. The visual difference comes less from bias-ply versus radial and more from the wheel diameter, sidewall height, and the tire series used in each correct size. A 16-inch setup presents differently from an 18-inch one even when both are proper fitments.
Appearance should still follow the exact sub-model and wheel package. Using the proper 205/65R16, 215/55R17, or 225/45R18 size helps preserve the intended stance and proportion of the car. If the goal is keeping the vehicle close to its original look, avoid guessing and confirm the trim and wheel setup first.
Does correct tire fitment matter for a 2013 Kia Optima restoration or refurbishment?
Correct tire fitment matters because the 2013 Kia Optima was offered with three different primary sizes across its trims, and each one supports a different wheel package and overall look. A refurbishment that uses the wrong rim diameter or profile can change the car’s stance and complicate future replacement choices.
Even on a newer collector or enthusiast-owned sedan, staying with the proper size for the exact trim keeps the presentation more consistent with the vehicle’s original configuration. For appearance-minded work, start by matching the wheel diameter and tire size, then compare available blackwall radial series within that fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Kia Optima?
Yes, modifications can affect tire fitment on a 2013 Kia Optima. Aftermarket wheels, suspension changes, lowering, or body modifications can alter the space available for the original 205/65R16, 215/55R17, or 225/45R18 sizes. Even when the tire size looks close, wheel width and overall package differences can change how the tire sits in the car.
A modified Optima should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension travel before selecting replacement tires. That is especially important on cars using 18-inch fitment or non-stock wheels. The tire sidewall marking and the actual wheel measurements should agree before a new set is chosen.
What should I inspect before driving a 2013 Kia Optima on new tires?
Before driving a 2013 Kia Optima on new tires, inspect the wheel diameter and tire size match, then confirm inflation pressure, bead seating, and general tire condition. It is also smart to check for visible rubbing points, damaged wheels, and uneven suspension wear that may affect how the new tires contact the road.
A short local drive followed by another visual inspection is a practical next step. Look for any signs of contact at the fender liner, strut area, or during tight turns. New tires can highlight existing alignment or suspension issues, so early inspection helps catch a fitment or wear problem before it becomes more expensive.
How often should tires on a 2013 Kia Optima be inspected?
Tires on a 2013 Kia Optima should be inspected regularly, not just when tread looks low. Pressure loss, irregular wear, cuts, bulges, and sidewall damage can develop gradually, especially on a daily-driven midsize sedan. Visual checks and pressure checks should be part of routine ownership rather than something saved for service visits only.
Inspection becomes even more important if the car has been sitting, driven on rough roads, or fitted with non-stock wheels. Checking the tires before longer trips is a sensible habit, and any unusual vibration or pull should prompt a closer look. Staying ahead of wear and air loss protects both fitment and drivability.
