Lexus GS F Tires

Lexus GS F uses two tire sizes across all model years from 2016 through 2020: 255/35R19 and 275/35R19. Both sizes are radial tires for 19-inch wheels, and both appear throughout the full production span rather than being tied to an early or late production change. The difference between them is width, with one size narrower and the other wider.

That means a Lexus GS F owner should treat size selection as an axle-position question, not just a model-year question. Check the size marking on the tire already mounted to the car, then confirm the wheel width as well, since listed 255/35R19 products are suited to narrower wheel widths than listed 275/35R19 products. Replacing tires in matched pairs by axle is the practical approach on a staggered setup.

On a Lexus GS F, 255/35R19 is a modern metric radial size code. The 255 number is the tire's section width in millimeters, 35 is the aspect ratio, meaning the sidewall height is 35 percent of the section width, R means radial construction, and 19 is the rim diameter in inches. The listed products in this size are all radial tires for 19-inch wheels.

Understanding that code helps prevent two common mistakes: confusing section width with tread width and overlooking the wheel diameter. A Lexus GS F owner comparing replacement options should also note the wheel-width range where provided, because the listed 255/35R19 tires are intended for 8.5 to 10.0 inch rims. Matching all of those dimensions matters more than matching the model year alone.

A 2018 Lexus GS F has two tire sizes listed because the car uses a staggered fitment, and that same two-size arrangement appears in every Lexus GS F year from 2016 through 2020. The two sizes share the same 19-inch rim diameter and the same radial construction type, so the split is not caused by a wheel-diameter change or a bias-ply versus radial choice. The difference is the vehicle configuration across front and rear positions.

That practical takeaway is simple: do not assume one size belongs on all four corners of a Lexus GS F. Check each axle before replacing a tire, especially if the car has had previous wheel or tire changes. When the sizes differ front to rear, keeping the correct size on the correct axle preserves intended handling balance and avoids avoidable fitment problems.

Lexus GS F uses 19-inch wheels with both listed tire sizes, 255/35R19 and 275/35R19, across every model year from 2016 through 2020. There is no rim diameter change within the production run in the available fitment range. The 19 at the end of each metric size code is the wheel diameter in inches.

That makes rim-diameter verification straightforward on a Lexus GS F, but it is still worth confirming the actual wheels on the car if you are working with a used example. Performance sedans often receive aftermarket wheel changes, and the original tire size guidance only applies when the car still carries 19-inch wheels with the appropriate width range for the chosen front or rear tire size.

A 2017 Lexus GS F uses the same two sizes found across the whole model run: 255/35R19 and 275/35R19. Since both sizes appear in the same year and both use 19-inch wheels, the deciding factor is the wheel position and the wheel width, not a year-based change. The narrower size and the wider size serve different places on the car.

Start by reading the sidewall of the tire already mounted on the axle you are replacing, then compare that with the wheel width if needed. The listed 255/35R19 products suit narrower wheel widths than the listed 275/35R19 products where specifications are provided. That step matters most when replacing a single axle set on a Lexus GS F with staggered tires.

The listed Lexus GS F tire options are all blackwall designs. That applies across both available sizes, 255/35R19 and 275/35R19, and across the brands represented in the current product range. There are no alternate whitewall or specialty sidewall treatments in the available fitment set.

For a Lexus GS F, blackwall construction is consistent with the car's modern high-performance character and keeps the appearance close to what most owners expect on a contemporary sport sedan. If appearance matters as much as performance, compare the sidewall styling details among the available performance series, but plan on staying within blackwall options for correct visual character.

The listed Lexus GS F tire options come from BFGoodrich and Nitto. BFGoodrich appears in both available sizes with multiple g-Force series options, while Nitto appears in the 275/35R19 size with the NT555 G2. All listed products for Lexus GS F are radial blackwall tires built around modern performance use.

Brand choice on a Lexus GS F is less about basic fit and more about the balance you want between all-season use, performance emphasis, and tread design within the correct size. Once the front or rear size is confirmed, compare the available series within that size rather than assuming the same lineup exists for both axle positions.

Lexus GS F fitments are available in several distinct tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. All are radial performance-oriented designs for 19-inch wheels, but they represent different product families rather than one identical tire sold in multiple sizes. Some are offered in both Lexus GS F sizes, while others appear only in one size.

That matters because a Lexus GS F owner may need to balance front and rear availability as well as preferred driving character. If you want the same tire family on both axles, first verify that the series is offered in both 255/35R19 and 275/35R19. Then compare wheel-width compatibility and service descriptions so the complete set works together as intended.

A Lexus GS F should be stored on clean, properly inflated tires in a cool, dry, dark environment away from direct sunlight, ozone sources, and large temperature swings. Because Lexus GS F uses low-profile 19-inch performance tires, extended underinflation during storage can encourage flat spotting and sidewall stress more quickly than on a taller touring tire. Keeping the car and tires clean also helps preserve the rubber and makes later inspections easier.

If the Lexus GS F will sit for long periods, move it occasionally or support it in a way that reduces prolonged load on one contact patch. Check inflation before and after storage rather than assuming the pressure has held. A little routine attention during downtime usually does more for collector and enthusiast tire life than simply letting the car sit untouched.

Tires on a Lexus GS F should be inspected regularly even if the car is driven only occasionally. A visual check before drives and a more careful inspection at least several times a year is a sensible routine for a performance sedan on low-profile radials. Look for uneven wear, cracking, punctures, sidewall damage, and any change in how the tire is seated on the wheel.

Inspection is especially important on a staggered Lexus GS F because front and rear tires are different sizes and can wear differently. Pay attention to shoulder wear, impact damage from potholes, and any vibration that develops after storage or limited seasonal use. Catching those issues early helps you correct alignment, pressure, or wheel-condition problems before they shorten tire life.

A Lexus GS F tire should be replaced when age, cracking, impact damage, persistent vibration, or structural concerns appear, even if the tread still looks usable. Low annual mileage can fool owners into thinking a performance tire is still serviceable simply because the grooves remain deep. Rubber ages with time as well as use, and that aging matters on any modern high-performance radial.

The practical rule is to treat calendar age and condition as seriously as tread depth on a Lexus GS F. Check the date code and have older tires inspected by a qualified tire professional who understands performance applications. If the car feels less stable, noisier, or harsher than before, do not assume that tread depth alone means the tire is still fit for continued road use.

The listed Lexus GS F tires are modern radial performance tires built for 19-inch wheels, and they are intended for normal road use when they are the correct size for the wheel and axle position. Safety depends on correct fitment, proper inflation, sound wheel condition, and overall tire age and condition rather than on size designation alone. A mismatched or aging tire can compromise a high-performance sedan quickly.

For a Lexus GS F, road safety starts with using the proper 255/35R19 or 275/35R19 size where it belongs and keeping tires in matched pairs by axle. After installation, confirm pressures, inspect for rubbing or clearance issues, and pay attention to ride quality and steering response during the first miles. Modern performance cars reveal tire problems early if the fit or condition is wrong.

Before driving a Lexus GS F, check tire pressure, visible sidewall condition, tread condition, and whether the correct size is mounted on the correct wheel position. Since Lexus GS F uses two sizes across a staggered 19-inch setup, one of the most important checks is making sure the narrower and wider tires have not been swapped to the wrong axle. Also look for punctures, bulges, or damage from curb contact.

A short walk-around before a drive is especially valuable if the Lexus GS F has been parked for a while. Performance tires can lose pressure gradually, and low-profile sidewalls do not always make that obvious at a glance. If anything feels unusual once underway, such as pulling, vibration, or harsh impact response, stop and inspect before continuing at speed.

A Lexus GS F should only be driven at speeds appropriate to current road conditions, tire condition, inflation, and the service description of the specific tire installed. The listed tires include performance-oriented ratings such as W and Y on certain products, but those ratings apply only when the tire is in proper condition and used exactly as intended. Age, damage, or incorrect fitment can reduce real-world safety long before any rated speed is relevant.

In practical terms, Lexus GS F owners should think about stability, condition, and setup before thinking about maximum speed potential. Keep the tires matched by axle, maintain proper inflation, and avoid high-speed driving on tires of uncertain age or after hard impacts. A modern performance sedan can mask tire problems until loads rise, so conservative judgment is part of safe use.
