Genesis G80 Tires

Genesis G80 fitments span eight sizes across model years 2017 through 2026. For 2017-2020, the listed sizes are 245/45R18 on 18-inch wheels, plus 245/40R19 and 275/35R19 on 19-inch wheels. For 2021-2026, the listed sizes are 245/50R18 on 18-inch wheels, 245/45R19 and 275/40R19 on 19-inch wheels, and 245/40R20 with 275/35R20 on 20-inch wheels.

That means a Genesis G80 owner needs to match both the year and the actual wheel package on the car. Some years use more than one wheel diameter, and some combinations are staggered with a narrower front tire and wider rear tire. Read the size molded into the sidewall of the existing tire and compare it with the year-specific list before choosing a replacement.

The 2021 Genesis G80 has five listed tire sizes because that model year includes several wheel package combinations rather than one universal fitment. The sizes break across three wheel diameters: 245/50R18 for 18-inch wheels, 245/45R19 and 275/40R19 for 19-inch setups, and 245/40R20 with 275/35R20 for 20-inch setups. Some of those are paired as front and rear sizes on staggered configurations.

A 2021 Genesis G80 owner should identify whether the car has 18-, 19-, or 20-inch wheels and then confirm whether the same size is used at all four corners or whether the rear tires are wider. The easiest way is to check the sidewall markings on both front and rear tires. If the front and rear numbers differ, replace each axle with the matching size rather than assuming a square setup.

Genesis G80 uses 18-inch, 19-inch, and 20-inch rim diameters within the 2017-2026 range. The early years already include both 18-inch and 19-inch wheel fitments, and 20-inch fitments appear beginning in 2021. The rim diameter is the final number in each listed tire size, so R18 means an 18-inch wheel, R19 means a 19-inch wheel, and R20 means a 20-inch wheel.

Because more than one wheel diameter can apply within the same generation, wheel size should be verified on the car rather than guessed from the model year alone. A Genesis G80 with 19-inch wheels cannot use an 18-inch or 20-inch tire, even if the overall stance looks similar. Checking the stamped wheel size and the current tire sidewall together is the safest way to avoid a mismatch.

On a Genesis G80, 245/45R19 means the tire is 245 millimeters wide, has a sidewall height equal to 45 percent of that width, uses radial construction, and fits a 19-inch wheel. That sizing format is common on modern performance and luxury sedans because it describes the tire's shape and the wheel diameter in one code. The same logic applies to the other Genesis G80 sizes in this range.

Understanding the code matters because two Genesis G80 tires can share the same wheel diameter while differing in width or sidewall height. A 245/45R19 and a 275/40R19 both fit 19-inch wheels, but they are not interchangeable side to side if the car uses a staggered setup. Always match the full size code, not just the final wheel diameter number.

A 2023 Genesis G80 can use 245/50R18, 245/45R19 with 275/40R19, or 245/40R20 with 275/35R20, depending on wheel package and whether the car is staggered front to rear. That means the year alone is not enough to identify the correct tire. The existing tire sidewall and the wheel itself will tell you whether the car is on 18-, 19-, or 20-inch wheels and whether the rear tires are wider than the fronts.

Start by reading the size on the front tire, then check the rear tire separately instead of assuming they match. On a staggered Genesis G80, the rear size will be different and wider. If the car has had aftermarket wheel changes, compare the actual installed sizes and wheel diameters against the combinations listed for the model year before deciding which replacement tire belongs on the car.

Genesis G80 tires in the listed range appear with Blackwall, RWL, and Redline sidewall styles. Blackwall options are available across the full spread of modern radial performance sizes, while RWL and Redline appear in certain Pro-Trac Street Pro III offerings for 245/50R18, 245/40R20, and 275/35R20. That creates a broader cosmetic range than many late-model luxury sedans typically receive.

A Genesis G80 owner looking for a factory-like modern appearance will usually gravitate toward blackwall tires. RWL and redline choices can create a more custom or retro-inspired visual effect, so they make the most sense when the wheel and styling theme already support that look. If preserving an understated luxury presentation is the goal, matching sidewall style across all four corners is especially important.

Genesis G80 tires in these fitments are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across much of the 18-, 19-, and 20-inch spread with g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. Nitto is represented by the NT555 G2, while Pro-Trac appears in the Street Pro III line on selected sizes.

That brand mix gives a Genesis G80 owner a choice between more conventional blackwall performance radials and selected specialty sidewall treatments in certain sizes. The right brand depends less on the badge itself than on whether the tire is offered in your exact wheel diameter and front or rear fitment. On staggered cars, check that both axle sizes are available in the same overall style before mixing brands or series.

Genesis G80 fitments are represented by several tire series: BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III. All are radial tires, but they differ in branding, available wheel diameters, and sidewall presentation. Street Pro III is the series that introduces RWL and redline sidewall choices in the listed Genesis G80 sizes, while the BFGoodrich and Nitto offerings shown here are blackwall selections.

For a Genesis G80 owner, the practical question is not only which series sounds familiar but which one is offered in the exact front and rear sizes the car uses. A 20-inch staggered setup has a different menu than an 18-inch package. Compare the available series within your size first, then decide whether appearance, matching front-to-rear style, or staying with a particular brand matters most for the finished result.

A Genesis G80 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and long periods of extreme temperature. Tires age more gracefully when the car is kept indoors, moved occasionally, and not left standing in one position for months at a time. Maintaining the tires at the vehicle maker's recommended pressure also helps reduce flat spotting and sidewall stress during storage.

If a Genesis G80 will sit for an extended period, roll the car slightly from time to time or place it on appropriate supports if that suits the overall storage plan. Check pressures before and after storage rather than assuming they stayed constant. Cars with staggered tire setups deserve extra attention, since front and rear tires are not interchangeable and uneven wear can be harder to correct later.

Tires on a Genesis G80 should be inspected regularly even if the car is driven only occasionally. A monthly visual check is a sound baseline, and another inspection before any longer drive is wise. Look for pressure loss, irregular shoulder wear, cuts, sidewall bulges, and any mismatch between front and rear sizes that might indicate a previous incorrect replacement.

A Genesis G80 with 19-inch or 20-inch low-profile tires can reveal alignment or impact issues sooner than a taller sidewall tire, so early inspection pays off. Also check tread depth across the full width rather than only in the center. If one axle shows unusual wear while the other looks normal, investigate alignment, suspension condition, and inflation pressure before fitting another set of tires.

Tires on a Genesis G80 should be replaced when age, cracking, impact damage, bulges, repeated air loss, or hardening of the rubber make them questionable, even if tread depth still looks acceptable. Collector-minded owners often focus on mileage, but calendar age matters just as much. A tire that appears lightly worn can still be compromised by time, heat cycles, and long stationary storage.

The practical rule for a Genesis G80 is to treat visible aging or structural concerns as a replacement signal rather than trying to use up the remaining tread. If the car has staggered sizing, compare front and rear condition separately because one axle may age or wear differently. Any vibration, impact bruise, or sidewall deformation deserves prompt evaluation before the car returns to regular road use.

The listed Genesis G80 tires are modern radial road tires in the sizes used across the 2017-2026 model range, so they are intended for normal public-road use when fitted in the correct size and maintained properly. Safety depends on using the right wheel diameter, the correct front and rear size where staggered fitments apply, and tires that are in sound condition. A mismatched size can affect handling, braking balance, and electronic system behavior.

Before driving, make sure every Genesis G80 tire matches the installed wheel diameter and that the front-to-rear pairing is correct for the car's configuration. Also inspect pressures, tread condition, and any signs of curb or pothole damage, especially on the lower-profile 19-inch and 20-inch combinations. Safe road use comes from correct fitment and condition together, not from size code alone.

Before driving a Genesis G80, check inflation pressure, tire condition, and whether the front and rear tires are the correct matching pair for the wheel package. On this model, that means confirming whether the car uses 18-inch, 19-inch, or 20-inch wheels and whether the rear tires are wider than the fronts. Also look for cuts, punctures, bulges, uneven wear, and any damage from potholes or curb strikes.

A quick walkaround can prevent bigger problems on a Genesis G80, particularly if the car is not driven every day. Read the sidewall on all four tires instead of assuming the same size is fitted everywhere. If one tire differs from the others in brand, series, or dimensions, confirm that it belongs there and has not been installed as a temporary mismatch after a previous replacement.

A Genesis G80 should always be driven within legal limits, road conditions, and the capability of the specific tires fitted to the car. The listed products include modern ZR-size radial performance tires, but appropriate speed is still governed by proper inflation, condition, load, alignment, and whether the full set matches the intended configuration. A luxury sport sedan can expose tire problems quickly if one axle is mismatched or underinflated.

The sensible approach for a Genesis G80 is to treat tire condition and setup as the first limiters, not the car's performance reputation. If the vehicle has recently received replacement tires, verify that the steering feels stable and the car tracks correctly before any sustained highway use. Any vibration, pull, or unusual response is reason to stop and inspect the tires and wheel package again.
