The 2020 Kia Stinger brought rear-drive sport-sedan character to Kia’s lineup with fastback styling, available all-wheel drive, and trim levels that range from well-equipped touring use to more aggressive GT performance. Tire selection matters because this model uses more than one factory-size layout, including an 18-inch fitment on the GT-Line and a staggered 19-inch setup on GT, GT1, and GT2 trims. That means the real decision starts with identifying the exact trim and whether the car uses matching or front-and-rear-specific sizes. From there, the focus shifts to choosing the right radial tire series, brand, and wheel-compatible fitment for the way the car is driven and presented.
Which Tire Size Is Right for The 2020 Kia Stinger
The 2020 Kia Stinger uses three primary tire sizes, and the correct one depends on the exact trim and wheel setup. GT-Line models use an 18-inch radial fitment, while GT, GT1, and GT2 trims use a staggered 19-inch arrangement with different front and rear sizes. Before choosing a tire, confirm both the sub-model and the wheel diameter, then make sure the tire is going to the correct axle position on staggered applications.
Fit(s): GT (AWD) Front, GT (RWD) Front, GT1 (AWD) Front, GT1 (RWD) Front, GT2 (AWD) Front, and GT2 (RWD) Front
Construction: Radial|Rim: 19 in
225/40R19 is a metric radial size in which 225 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2020 Kia Stinger, this size serves as the front tire on 19-inch staggered GT, GT1, and GT2 applications. Available choices are centered on blackwall performance radials from BFGoodrich in series such as g-Force Comp 2 AS and g-Force Phenom T/A. This size is the one to evaluate when the car has the 19-inch front setup and the goal is to match the correct front fitment rather than a square arrangement.
255/35R19 is a metric radial size where 255 denotes nominal section width in millimeters, 35 is the aspect ratio, R marks radial construction, and 19 is the wheel diameter in inches. This is the rear tire size on staggered 19-inch 2020 Kia Stinger GT, GT1, and GT2 configurations, giving the rear axle a wider fitment than the front. BFGoodrich offers this size in blackwall form across g-Force series including Comp 2 AS, Sport Comp 2, and Phenom T/A. It is the correct size to review when replacing rear tires on a staggered Stinger rather than choosing a single size for all four corners.
225/45R18 is a metric radial size that uses a 225-millimeter nominal section width, a 45-series profile, radial construction, and an 18-inch rim diameter. On the 2020 Kia Stinger, this size is used on the GT-Line and represents the non-staggered 18-inch fitment within this model range. Product choices include blackwall radials from BFGoodrich and Nitto, with 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 compare when the car is a GT-Line and the priority is choosing among available performance-oriented radial options in the correct 18-inch format.
Sub-model fitment matters on the 2020 Kia Stinger because tire size changes with both trim level and axle position. GT-Line uses an 18-inch setup, while GT, GT1, and GT2 models use staggered 19-inch front and rear sizes that should be matched to the correct position on the car.

2020 Kia Stinger GT (AWD) Front
The 2020 Kia Stinger GT (AWD) Front uses the 225/40R19 radial size as part of the model’s staggered 19-inch setup. Tire selection here should stay focused on the front axle position and on matching the wheel diameter and intended handling balance of the GT layout.
The 2020 Kia Stinger GT (AWD) Rear uses the wider 255/35R19 radial size on a 19-inch wheel. That makes rear tire choice distinct from the front, so replacement should be based on the rear fitment rather than assuming the same size belongs at all four corners.
The 2020 Kia Stinger GT (RWD) Front uses 225/40R19 in radial construction. Choosing this position correctly means confirming the front axle fitment on the staggered 19-inch setup and comparing performance-oriented tire options within that exact size.
The 2020 Kia Stinger GT (RWD) Rear uses 255/35R19, giving the rear axle a wider tire than the front. That matters when replacing only two tires or rebuilding a matched set, because the rear size should not be confused with the narrower front fitment.
The 2020 Kia Stinger GT-Line uses the 225/45R18 radial size on its 18-inch setup. Tire selection is more straightforward here than on the staggered GT models, with the main decision shifting to brand, tire series, and wheel-compatible performance radial options.
The 2020 Kia Stinger GT1 (AWD) Front uses 225/40R19 as the front portion of the 19-inch staggered arrangement. The practical takeaway is to shop this size as a front-specific fitment and avoid mixing it up with the wider rear tire used on the same trim.
The 2020 Kia Stinger GT1 (AWD) Rear uses 255/35R19 radial tires on a 19-inch wheel. This rear-specific size should be matched to the correct axle position, especially when replacing a pair, maintaining a staggered setup, or comparing different tire series.
The 2020 Kia Stinger GT1 (RWD) Front uses the 225/40R19 radial fitment. Buyers should treat this as the front half of a staggered 19-inch package and compare tires in that exact size instead of treating the car as a square four-tire application.
The 2020 Kia Stinger GT1 (RWD) Rear uses 255/35R19, separate from the front size used on the same vehicle. That means rear-tire replacement should account for the wider axle-specific fitment and for the tire series choices available in this size.
The 2020 Kia Stinger GT2 (AWD) Front uses 225/40R19 in radial construction. Choosing correctly here starts with recognizing that GT2 uses a staggered 19-inch layout, so front tire selection should stay tied to the front axle and its wheel dimensions.
The 2020 Kia Stinger GT2 (AWD) Rear uses the 255/35R19 radial size. That rear fitment changes the buying decision, since the tire needs to suit the back axle’s wider setup rather than simply matching the front size out of convenience.
The 2020 Kia Stinger GT2 (RWD) Front uses 225/40R19 on a 19-inch wheel. Tire selection should remain front-specific on this staggered configuration, with attention paid to choosing a radial tire series that suits the car’s road use and wheel width.
The 2020 Kia Stinger GT2 (RWD) Rear uses 255/35R19, the wider rear fitment used on the GT2 staggered package. This is the size to verify before replacement so the rear axle keeps the intended fitment relationship with the 225/40R19 front tires.
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 2020 Kia Stinger?
The 2020 Kia Stinger uses three primary tire sizes: 225/45R18, 225/40R19, and 255/35R19. GT-Line models use 225/45R18, while GT, GT1, and GT2 trims use a staggered 19-inch setup with 225/40R19 in front and 255/35R19 in the rear.
The key step is identifying the exact trim and whether the car has the 18-inch non-staggered arrangement or the 19-inch front-and-rear-specific layout. On staggered cars, front and rear tires are not the same size, so replacement should be matched to the correct axle position as well as the wheel diameter.
What size rim does a 2020 Kia Stinger use?
A 2020 Kia Stinger uses either an 18-inch or 19-inch rim depending on the sub-model. The GT-Line uses an 18-inch fitment with 225/45R18 tires, while GT, GT1, and GT2 trims use 19-inch wheels with 225/40R19 front tires and 255/35R19 rear tires.
Wheel diameter should be confirmed before ordering tires, especially if the car has changed hands or has aftermarket wheels. The size molded on the current tire and the actual wheel measurement should agree, and staggered 19-inch cars also need front and rear positions checked separately before replacement.
Why does the 2020 Kia Stinger have more than one tire size?
The 2020 Kia Stinger has more than one tire size because different trims use different wheel and tire layouts. The GT-Line uses a single 18-inch size, while GT, GT1, and GT2 models use a staggered 19-inch setup with one size for the front axle and a wider size for the rear.
That means tire selection is tied to configuration, not just year and model name. A buyer should confirm trim level first, then verify whether the car still carries its original wheel setup. On 19-inch GT-based trims, replacing the wrong axle size can upset the intended front-to-rear fitment relationship.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Kia Stinger?
Start with the correct size for the exact 2020 Kia Stinger trim and axle position. GT-Line uses 225/45R18, while GT, GT1, and GT2 models use 225/40R19 in front and 255/35R19 in the rear, so wheel diameter and staggered positioning come before brand or series choice.
After size is confirmed, compare construction details such as rim-width compatibility, tire series, and load information where it is stated. A car driven year-round may call for a different product approach than one used mainly for fair-weather touring, and a staggered setup should be kept balanced from front to rear.
What brands offer tires for the 2020 Kia Stinger?
Tires for the 2020 Kia Stinger are available here from BFGoodrich and Nitto, depending on size. BFGoodrich appears across all three primary sizes, while Nitto is offered in 225/45R18 for the GT-Line 18-inch fitment.
Brand choice should still come after fitment is nailed down. A GT-Line owner can compare across both BFGoodrich and Nitto in the 18-inch size, while owners of GT, GT1, and GT2 trims will be choosing among BFGoodrich radial options in the two 19-inch staggered sizes.
What tire series are available for the 2020 Kia Stinger?
Available tire series for the 2020 Kia Stinger include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. The exact series selection depends on the tire size, with the broadest variety appearing in 225/45R18 and 255/35R19.
Series choice matters because it helps distinguish one performance-oriented radial option from another even within the same size. Once the correct fitment is confirmed, compare the series alongside rim-width range, load detail when shown, and whether the tire is going on a GT-Line or a staggered 19-inch GT-based trim.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Kia Stinger?
A period-style approach on a 2020 Kia Stinger starts with keeping the correct original-format sizing for the exact trim. That means 225/45R18 on a GT-Line or the staggered 225/40R19 front and 255/35R19 rear setup on GT, GT1, and GT2 models, all in modern radial construction.
Appearance on this generation is more about preserving the intended stance and wheel-to-tire relationship than choosing a vintage sidewall treatment. Staying with the proper size and axle placement keeps the car visually coherent, while wheel changes or mismatched sizes can alter the look even before they affect fitment.
Does correct tire fitment matter for a 2020 Kia Stinger restoration?
Correct tire fitment does matter on a 2020 Kia Stinger because the model’s look and setup vary by trim. A GT-Line wears an 18-inch package, while GT-based trims rely on a staggered 19-inch front and rear combination that contributes to the car’s intended visual balance and overall presentation.
Even on a newer collector candidate, the right size helps preserve the stance the car was designed around. Owners aiming for originality in appearance should verify the wheel package actually on the car and avoid assuming that one size works across all trims or all four corners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Kia Stinger?
Yes, modifications can affect tire fitment on a 2020 Kia Stinger. Aftermarket wheels, suspension changes, altered ride height, or attempts to convert a staggered setup into a square one can all change the wheel width, clearance, and axle-specific fitment requirements that the original tire sizes were chosen around.
Any modified Stinger should have wheel diameter, wheel width, and front-to-rear clearance checked before a new set is chosen. On GT, GT1, and GT2 models, it is especially important to confirm whether the car still uses 225/40R19 front and 255/35R19 rear rather than assuming the stock layout remains in place.
What should I inspect before driving a 2020 Kia Stinger on new tires?
Before driving a 2020 Kia Stinger on new tires, inspect the wheel size, mounting position, inflation, and overall tire condition. On staggered 19-inch trims, confirm that 225/40R19 tires are on the front and 255/35R19 tires are on the rear, and make sure the tires seat properly on the correct wheel widths.
It is also smart to check for rubbing during full steering lock and over suspension movement, especially if the car has aftermarket wheels or prior alignment changes. A short road test followed by a pressure recheck can help catch installation or clearance issues before the vehicle is put into regular use.
How often should tires on a 2020 Kia Stinger be inspected?
Tires on a 2020 Kia Stinger should be inspected regularly, not just when tread looks low. Check them for uneven wear, sidewall damage, punctures, air loss, and signs that front and rear tires may have been mixed up on staggered 19-inch trims where the axle positions use different sizes.
A monthly visual inspection and pressure check is a sensible baseline, with extra attention before longer drives or seasonal use changes. Cars that sit for extended periods still need tire checks, since age, flat spotting, and gradual pressure loss can affect road manners even when the tread still appears usable.
