The 2020 Lexus GS F sits at the sharp end of the GS lineup, blending Lexus luxury-sedan refinement with the kind of rear-wheel-drive performance that rewards careful chassis setup. It is a modern performance car with a staggered tire layout, so tire selection is tied directly to preserving the balance between front turn-in and rear traction. The 2020 Lexus GS F uses 255/35R19 tires in front and 275/35R19 tires in the rear, both in radial construction on 19-inch wheels. Available choices include several performance-oriented radial series, primarily in blackwall form. The key is matching the correct front and rear sizes while confirming wheel specifications and any changes from the original wheel or suspension setup.
Which Tire Size Is Right for The 2020 Lexus GS F
The 2020 Lexus GS F uses two primary tire sizes, both on 19-inch rims, with 255/35R19 at the front and 275/35R19 at the rear. This is a staggered radial fitment, so the first step is confirming whether you are replacing the front pair or the rear pair. Once that is established, the decision shifts to comparing available performance tire series, brand options, and wheel-width compatibility within the correct position-specific size.
In 255/35R19, the 255 refers to nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2020 Lexus GS F, this size serves the front position and supports the car's steering response and front-end balance. Available options include BFGoodrich choices from the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, all in blackwall form. This is the size to evaluate when replacing the front tires and confirming that wheel width stays within the tire's intended range.
In 275/35R19, the 275 is the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 19 identifies the wheel diameter in inches. On the 2020 Lexus GS F, this is the rear tire size, where the wider section supports the car's staggered performance layout. Product choices include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2, all with blackwall styling. This is the size to focus on when replacing the rear tires and checking that the wheel and tire package remains appropriate for the car's rear clearance.
Sub-model fitment on the 2020 Lexus GS F is straightforward in name but position-specific in practice. The covered front and rear applications use different sizes, so identifying which axle you are servicing matters before choosing a tire.

2020 Lexus GS F Base Front
The 2020 Lexus GS F Base Front uses the narrower of the two primary radial sizes and is part of the car's staggered 19-inch setup. Tire selection here centers on choosing a front-position performance tire that matches the wheel width and maintains the intended front-end feel.
The 2020 Lexus GS F Base Rear uses the wider rear radial size, which is separate from the front fitment and should not be treated as interchangeable by default. Rear tire selection is best approached by confirming the wheel setup, then comparing available performance tire series for the correct rear position.
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 Lexus GS F?
The 2020 Lexus GS F uses a staggered setup with 255/35R19 tires at the front and 275/35R19 tires at the rear. Both are radial sizes mounted on 19-inch wheels, so the car does not use the same tire size at all four corners.
That staggered layout means replacement starts with identifying which axle needs tires. Front and rear sizes serve different positions, so the wheel location matters just as much as the rim diameter. It is also smart to confirm that the car still has the correct wheel widths and that no aftermarket wheel or suspension changes have altered the fitment.
What size rim does a 2020 Lexus GS F use?
The 2020 Lexus GS F uses 19-inch rims with both of its primary tire sizes. The front 255/35R19 and rear 275/35R19 are both built around a 19-inch wheel diameter, even though the tire widths differ from front to rear.
Rim diameter is only part of the fitment picture on a performance sedan like the GS F. Wheel width still needs to match the tire you choose, especially with a staggered setup. Checking the actual front and rear wheel specifications before buying helps avoid selecting a tire that suits the diameter but not the wheel or intended axle position.
Why does the 2020 Lexus GS F have more than one tire size?
The 2020 Lexus GS F uses more than one tire size because it has a staggered fitment, with 255/35R19 in front and 275/35R19 in the rear. The rear tire is wider than the front, which is common on rear-wheel-drive performance cars.
That layout affects how the car balances steering response and rear traction, so size choice is tied to position on the vehicle. A front-size tire should not simply be substituted for the rear, or vice versa, without a full wheel and clearance review. Matching the proper axle-specific size keeps the tire selection aligned with the car's intended setup.
Choosing the Right Tire
What should I consider when choosing 2020 Lexus GS F tires?
Start with the correct axle-specific size: 255/35R19 for the front and 275/35R19 for the rear. From there, compare radial tire series, wheel-width compatibility, and product details such as load capacity where stated, since the GS F depends on a properly matched staggered setup.
The right choice often comes down to how the car is used and whether the wheel package remains original. A daily-driven sedan may call for a different product emphasis than a fair-weather performance car. Keeping front and rear fitment separate during the buying process helps narrow the choices quickly and avoids mixing sizes incorrectly.
What brands offer tires for the 2020 Lexus GS F?
Tires for the 2020 Lexus GS F are available from BFGoodrich and Nitto in the sizes used by this car. BFGoodrich appears in both the front and rear fitments, while Nitto is offered in the rear 275/35R19 size.
Brand choice should be considered alongside the exact tire series, not by name alone. Some owners may be comparing options for both axles at once, while others only need a rear replacement. Looking at the brand within the correct size and position makes it easier to compare wheel-width suitability and the general character of the available product lines.
What tire series are available for the 2020 Lexus GS F?
The 2020 Lexus GS F has several tire series available within its front and rear fitments, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. In the rear 275/35R19 size, the Nitto NT555 G2 is also available.
Series matters because it helps distinguish one product line from another even when the tire size is correct. That becomes especially useful on a staggered performance car where owners may want to keep the same line front to rear when possible. Comparing series within the correct axle position keeps the focus on fitment first, then product character.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Lexus GS F?
A period-style approach on a 2020 Lexus GS F still begins with the correct modern staggered sizes, 255/35R19 front and 275/35R19 rear. Since the available products are radial blackwall performance tires, the visual direction stays true to the car's contemporary sport-sedan character rather than a vintage presentation.
Selection is less about whitewalls or classic sidewall treatments and more about keeping the overall stance and wheel relationship intact. Owners aiming for an original-looking presentation should verify the actual wheel setup and avoid changing tire proportions casually. Preserving the intended front-to-rear visual balance matters as much as choosing the correct nominal size.
Does correct tire fitment matter for a 2020 Lexus GS F restoration or preservation project?
Correct tire fitment matters on a 2020 Lexus GS F because the car uses a staggered modern performance layout rather than a one-size-fits-all arrangement. Keeping the proper 255/35R19 front and 275/35R19 rear sizing helps preserve the visual stance and operating character the car was designed around.
Preservation-minded owners should also pay attention to wheel width, overall tire condition, and whether prior modifications changed the setup. Even on a relatively modern collector car, incorrect proportions can alter appearance and create clearance or handling concerns. Matching the right size to the right axle is the foundation before comparing brands or tire series.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lexus GS F?
Yes, modifications can affect tire fitment on a 2020 Lexus GS F even when the nominal tire size remains 255/35R19 front and 275/35R19 rear. Aftermarket wheels, altered offsets, suspension changes, or ride-height changes can all change how much room the tire has at the fender, steering, and inner suspension areas.
That matters most on a staggered 19-inch setup because front and rear positions already use different widths. Any owner working with non-stock wheels should confirm actual wheel width and clearance before selecting tires. A fitment that seems close on paper can still create rubbing or geometry issues once the car is loaded, turned, or driven aggressively.
What should I inspect before driving a 2020 Lexus GS F on new tires?
Before driving a 2020 Lexus GS F on new tires, inspect the wheel condition, verify that the front and rear sizes were mounted in the correct positions, and check inflation pressure. It is also wise to confirm there is no visible contact issue at the fender, suspension, or steering components.
A short initial road test can reveal vibration, rubbing, or directional instability before the car goes on a longer drive. Rechecking pressure after installation is useful, and so is confirming that each tire suits the wheel width being used. On a staggered car, simple position mistakes can create avoidable handling and wear problems.
How often should tires on a 2020 Lexus GS F be inspected?
Tires on a 2020 Lexus GS F should be inspected regularly, especially because the car uses low-profile 19-inch performance sizes that can be sensitive to pressure loss, impact damage, and uneven wear. Routine checks should include tread condition, sidewall cuts or bulges, and any signs of irregular wear between the front and rear axles.
Frequent inspection is particularly important if the car is driven spiritedly or sits for long periods between outings. Looking over the tires before a longer drive can catch aging, punctures, or air loss early. Since the front and rear sizes differ, each axle should be checked on its own rather than assuming wear patterns will match.
