The 2020 Kia Forte sits in the modern compact-sedan class, where trim level makes a real difference in both appearance and driving character. From value-oriented daily-driver versions to the sharper GT models, the Forte uses radial tire fitments throughout, but not one single size across the range. Depending on the sub-model, the correct fitment is 195/65R15, 205/55R16, 225/45R17, or 225/40R18. That means the tire decision starts with confirming the exact trim and wheel diameter, then narrowing choices by brand, tire series, and sidewall treatment where available. For any Forte that has been modified, the actual wheel and clearance setup should be checked before selecting a replacement tire.
Which Tire Size Is Right for The 2020 Kia Forte
The 2020 Kia Forte uses four different primary tire sizes, and they vary by sub-model as well as rim diameter. Every fitment is a radial, but the first step is still identifying the exact Forte trim and confirming whether the car is running a 15-, 16-, 17-, or 18-inch wheel before comparing tire choices.
225/45R17 is a metric radial size where 225 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2020 Kia Forte, this size suits trims that use a 17-inch wheel and keeps the selection focused on modern radial construction. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, raised white letter, and Redline sidewall treatments depending on the tire series. It is a useful fitment to evaluate when the goal is matching the correct 17-inch setup while still choosing the look and product character that best fits the car.
195/65R15 is a metric radial size that uses a 195-millimeter section width, a 65-series profile, and a 15-inch rim diameter. Its taller sidewall profile compared with the larger-wheel Forte fitments reflects a trim-specific setup rather than a universal size across the model line. The practical meaning for a buyer is that wheel diameter matters just as much as tire size, since a 15-inch Forte setup calls for a different fitment path than the 16-, 17-, or 18-inch versions. This size should be chosen only after confirming the exact sub-model and current wheel package on the vehicle.
225/40R18 is a metric radial size with a 225-millimeter section width, a 40-series profile, and an 18-inch rim diameter. On the 2020 Kia Forte, it belongs to the trims that use the largest factory wheel diameter in this model range, making wheel confirmation especially important before replacement. Product choices in this size include BFGoodrich and Nitto lines, with Blackwall styling across g-Force and NT555 G2 series options. This fitment is the one to evaluate when the Forte has the 18-inch performance-oriented wheel package and the goal is staying with the correct size format.
205/55R16 is a metric radial size that combines a 205-millimeter section width with a 55-series aspect ratio on a 16-inch wheel. For the 2020 Kia Forte, it represents a trim-specific middle ground between the smaller 15-inch setup and the larger 17- and 18-inch fitments. Available products include BFGoodrich, Michelin, and American Classic choices, mostly in Blackwall form, with a Wide Whitewall option for buyers who want a more distinctive appearance. This size is worth closer comparison when the car uses a 16-inch wheel and the buyer wants to balance correct fitment with sidewall and series selection.
Tire fitment changes across the 2020 Kia Forte lineup, so identifying the exact sub-model is the key first step. Each covered trim uses one primary radial size, but the wheel diameter ranges from 15 to 18 inches, which makes trim confirmation essential before replacement.

2020 Kia Forte EX
The 2020 Kia Forte EX uses the 225/45R17 radial fitment on a 17-inch wheel. That makes the main decision less about alternate primary sizes and more about comparing available brands, tire series, and sidewall treatments within the correct 17-inch setup.
The 2020 Kia Forte FE uses the 195/65R15 radial size. Tire selection for this trim starts with staying on the correct 15-inch wheel diameter, then confirming that the car has not been changed to a different wheel package since new.
The 2020 Kia Forte GT uses the 225/40R18 radial fitment. This places the focus on the correct 18-inch wheel setup and on comparing the available performance-oriented radial choices offered in that size.
The 2020 Kia Forte GT M/T also uses the 225/40R18 radial size. Buyers shopping for this trim should confirm the existing 18-inch wheel package and then compare the available Blackwall tire series that match that fitment.
The 2020 Kia Forte GT-Line uses the same 225/45R17 radial size as the EX. That shared fitment keeps the size question simple, allowing the choice to center on brand, tire series, and appearance details such as Blackwall, raised white letter, or Redline styling.
The 2020 Kia Forte LXS uses the 205/55R16 radial fitment on a 16-inch wheel. Selecting tires for this trim means staying with the proper 16-inch size and then deciding whether a straightforward Blackwall look or a more distinctive Wide Whitewall presentation makes sense for the car.
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.

Common 2020 Kia Forte tire questions usually come down to trim-specific size, wheel diameter, product selection, and whether the car still has its original wheel setup. The answers below focus on fitment first, then on choosing among the available radial tire options.
Tire Size & Fitment
What tire size fits a 2020 Kia Forte?
A 2020 Kia Forte does not use one universal tire size across every trim. The correct primary fitment is 195/65R15, 205/55R16, 225/45R17, or 225/40R18, depending on the specific sub-model, and every one of those fitments is a radial.
The practical first step is confirming whether the car is an FE, LXS, EX, GT-Line, GT, or GT M/T, then checking the wheel diameter on the car itself. That matters because a Forte running a 15-inch setup requires a completely different tire size than one using 16-, 17-, or 18-inch wheels.
What size rim does a 2020 Kia Forte use?
The 2020 Kia Forte uses several rim diameters across the model range: 15-inch, 16-inch, 17-inch, and 18-inch. Rim diameter follows the tire size, so 195/65R15 uses a 15-inch rim, 205/55R16 uses a 16-inch rim, 225/45R17 uses a 17-inch rim, and 225/40R18 uses an 18-inch rim.
Wheel diameter should be verified before ordering replacement tires, especially if the car was bought used or has aftermarket wheels. A trim badge alone is helpful, but the actual wheel on the car is what determines whether the replacement tire will match the vehicle's present setup.
Why does the 2020 Kia Forte have more than one tire size?
The 2020 Kia Forte has more than one tire size because different sub-models were paired with different wheel diameters and tire profiles. FE uses 195/65R15, LXS uses 205/55R16, EX and GT-Line use 225/45R17, and GT and GT M/T use 225/40R18.
That means tire replacement starts with trim and wheel confirmation, not with a one-size-fits-all assumption. Even though the overall tire diameters stay relatively close, the rim size, section width, and profile differ enough that selecting by the exact sub-model is the safest way to narrow the correct fitment.
Choosing the Right Tire
What should I consider when choosing a 2020 Kia Forte tire?
The most important factor is selecting the exact tire size that matches the Forte's sub-model and wheel diameter. After that, the real comparison shifts to radial tire series, brand, rim-width compatibility, sidewall style where available, and whether the tire's general character suits the way the car is driven.
A Forte with 17-inch or 18-inch wheels presents a different choice set than one with 15-inch or 16-inch wheels, so trim confirmation comes first. It also helps to inspect the current wheel package, because a car that has been changed from stock may need a different fitment path than the original trim specification suggests.
What sidewall styles are available for 2020 Kia Forte tires?
Most available 2020 Kia Forte tire options use a Blackwall sidewall, but there is some variation by size. In 225/45R17, Blackwall, raised white letter, and Redline options appear, while 205/55R16 also includes a Wide Whitewall choice alongside more conventional Blackwall tires.
Sidewall style mainly affects appearance, so the right choice depends on whether the Forte is being kept understated or given a more distinctive look. The key is to separate appearance preference from fitment, since the tire still needs to match the correct trim-specific size and wheel diameter before sidewall styling becomes the deciding factor.
What brands offer tires for the 2020 Kia Forte?
Available 2020 Kia Forte tire brands include BFGoodrich, Nitto, Michelin, American Classic, and Pro-Trac, depending on the size. Brand availability changes with the trim-specific fitment, so a 17-inch or 18-inch Forte will not necessarily see the same mix of options as a 16-inch car.
Brand comparison works best after the correct size is confirmed, because tire series, sidewall choices, and rim-width specifications vary within each fitment. Instead of treating the whole Forte range as one category, it makes more sense to compare brands inside the exact size your car uses and the look you want.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Kia Forte?
A period-style approach on a 2020 Kia Forte still begins with the correct trim-specific radial size, since fitment does not become less important just because appearance is part of the goal. From there, the most distinctive visual choices appear in 225/45R17 with Redline or raised white letter styling, and in 205/55R16 with a Wide Whitewall option.
That kind of selection is more about creating a custom visual theme than duplicating an exact original-delivery look. Buyers who want the car to remain visually close to its standard modern presentation will usually stay with a Blackwall sidewall, while those building a more personalized car can compare the specialty sidewall treatments within the correct size.
How does tire construction affect the appearance of a restored 2020 Kia Forte?
On the 2020 Kia Forte, tire construction does not create a bias-ply-versus-radial appearance decision because the primary fitments are all radial. The visual differences instead come from sidewall treatment, tire series, and the wheel diameter tied to the specific trim.
That means appearance planning should focus on whether the car looks best with a simple Blackwall or with a more noticeable style such as Redline, raised white letter, or Wide Whitewall where offered. Keeping the correct size for the sub-model is still essential, because the wrong profile or rim diameter will change the car's stance more than sidewall styling alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Kia Forte?
Yes, modifications can affect tire fitment on a 2020 Kia Forte even when the original trim specification is known. Aftermarket wheels, changes in wheel width, suspension lowering, or other alterations can change the space available for the tire and may also alter which size is currently appropriate on the car.
A modified Forte should be checked at the wheel, not just by trim name. It helps to confirm actual wheel diameter, tire size currently installed, and the clearance around the strut, fender, and steering range before replacing tires, especially when moving between the Forte's different 15-, 16-, 17-, and 18-inch fitment families.
What should I inspect before driving a 2020 Kia Forte on new tires?
Before driving a 2020 Kia Forte on new tires, inspect the wheel for the correct diameter and general condition, and make sure the installed tire size matches the car's trim and setup. It is also smart to confirm proper inflation, check for even seating on the rim, and look over the suspension and alignment condition.
A quick road-use check should include turning the steering from lock to lock and watching for any unexpected rubbing if the car has non-stock wheels or suspension changes. Even with brand-new tires, the surrounding hardware still matters, and uneven wear can start early when alignment or suspension issues are left uncorrected.
How often should tires on a 2020 Kia Forte be inspected?
Tires on a 2020 Kia Forte should be inspected regularly rather than only when replacement time arrives. Frequent checks for inflation, tread wear, sidewall cuts, bulges, cracking, and air loss help catch problems early, especially on a daily-driven compact sedan where tire condition directly affects ride quality and road manners.
Inspection becomes even more important if the car has been parked for long periods or if a wheel change was made after purchase. Looking over the tires during routine maintenance and before longer trips is a practical habit, and it helps confirm that the current size and wheel package still match the way the Forte is being used.
