The 2017 Genesis G80 sits in the modern luxury sport-sedan category, blending rear-drive proportions, upscale road manners, and a more driver-focused character than many buyers expected from the Genesis name at the time. Tire choice on this car is tied closely to configuration, because the G80 uses three primary radial sizes: 245/45R18 on the 3.8, plus a staggered 19-inch setup of 245/40R19 front and 275/35R19 rear on the 5.0. Available options lean toward blackwall performance-oriented radial tires from BFGoodrich and Nitto across several series. The key is matching the exact sub-model and wheel diameter before comparing tread style, load capability, and intended driving use.
Which Tire Size Is Right for The 2017 Genesis G80
Three primary tire sizes apply to the 2017 Genesis G80, and the right one depends first on identifying the exact sub-model and wheel setup. The 3.8 uses an 18-inch radial tire, while the 5.0 uses a staggered 19-inch arrangement with different front and rear sizes. Before choosing a tire, confirm whether the car has the 18-inch single-size setup or the 19-inch front-and-rear combination.
A 245/45R18 tire uses a 245-millimeter section width, a 45-series aspect ratio, radial construction, and an 18-inch rim. On the 2017 Genesis G80, this is the primary fitment for the 3.8 and suits the car's standard 18-inch wheel package. In this size, available choices include BFGoodrich and Nitto, with blackwall sidewalls and 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 right starting point if the car is a G80 3.8 and still uses its 18-inch wheel diameter.
A 245/40R19 tire carries the same 245-millimeter section width as the 18-inch fitment, but with a shorter 40-series sidewall and a 19-inch rim diameter. On the 2017 Genesis G80, this size is used at the front of the 5.0's staggered setup, so it should be treated as part of a matched front-and-rear arrangement rather than a universal G80 size. Available options include blackwall performance radials from BFGoodrich in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. Choose this size only after confirming the car is a 5.0 front position on 19-inch wheels.
A 275/35R19 tire is wider than the front 5.0 fitment, using a 275-millimeter section width, a 35-series profile, radial construction, and a 19-inch rim. On the 2017 Genesis G80, this size is used at the rear of the 5.0, reflecting the car's staggered tire layout. Product choices include blackwall radial tires 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 is the correct size to evaluate only for the rear position of a G80 5.0 running the 19-inch setup.
Sub-model fitment matters on the 2017 Genesis G80 because tire size changes with both trim and wheel package. The 3.8 uses one 18-inch size, while the 5.0 uses a staggered 19-inch front-and-rear arrangement that requires position-specific tire selection.

2017 Genesis G80 3.8
The 2017 Genesis G80 3.8 uses a single 245/45R18 radial tire size, which keeps fitment relatively straightforward as long as the car remains on its 18-inch wheels. Tire selection then becomes a matter of comparing blackwall performance-oriented options, rim-width compatibility, and how the car is actually driven.
The 2017 Genesis G80 5.0 Front uses 245/40R19 radial tires as the front half of a staggered setup. That means front tire selection should stay coordinated with the matching rear size, while also confirming the car still has the proper 19-inch wheel configuration.
The 2017 Genesis G80 5.0 Rear uses 275/35R19 radial tires, a wider rear fitment paired with the 245/40R19 front size. Tire choice here should account for the staggered layout, rear wheel width, and whether the vehicle remains on its intended 19-inch rear wheel package.
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.
Best 2017 Genesis G80 Tires for Sale
Available 2017 Genesis G80 tire choices center on radial blackwall performance tires from BFGoodrich and Nitto. Depending on size, buyers can compare series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2, along with differences in rim-width range and load specification.
Common 2017 Genesis G80 tire questions usually come down to exact size by sub-model, 18-inch versus 19-inch wheel fitment, staggered front-and-rear selection on the 5.0, and how to compare the available blackwall radial tire options.
Tire Size & Fitment
What tire size fits a 2017 Genesis G80?
The 2017 Genesis G80 uses three primary tire sizes depending on configuration. The G80 3.8 uses 245/45R18, while the G80 5.0 uses a staggered 19-inch setup with 245/40R19 in front and 275/35R19 in the rear. All of these are radial tire sizes.
The practical step is to confirm both the exact sub-model and the wheel package on the car before selecting tires. A 3.8 on 18-inch wheels calls for a different fitment path than a 5.0 with staggered 19-inch wheels, and the 5.0 front and rear positions should not be treated as the same size.
What size rim does a 2017 Genesis G80 use?
The 2017 Genesis G80 uses either an 18-inch or 19-inch rim, depending on sub-model. The 3.8 uses an 18-inch rim with 245/45R18 tires, while the 5.0 uses 19-inch rims with 245/40R19 front tires and 275/35R19 rear tires.
Wheel diameter should be verified before anything else, especially if the car was bought used or may have been changed from stock wheel sizing. Once diameter is confirmed, compare the tire's approved rim-width range and make sure the front and rear wheel positions on a staggered 5.0 setup are matched to the correct tire size.
Why does the 2017 Genesis G80 have more than one tire size?
The 2017 Genesis G80 has more than one tire size because fitment changes by sub-model and wheel arrangement. The 3.8 uses a single 18-inch tire size, while the 5.0 uses a staggered 19-inch layout with one size in front and a wider size in the rear.
That difference affects more than just dimensions on paper. A staggered setup means the front and rear tires serve different positions, so selection has to follow the actual wheel arrangement on the car rather than assuming every G80 uses the same tire. Checking the door-jamb placard and actual mounted wheel sizes helps avoid ordering the wrong configuration.
Choosing the Right Tire
What should I consider when choosing a 2017 Genesis G80 tire?
Start with the exact tire size for the car's sub-model and wheel position: 245/45R18 for the 3.8, or 245/40R19 front and 275/35R19 rear for the 5.0. From there, compare radial construction details such as rim-width range, load capacity where stated, tire series, and the type of driving the car sees most often.
A G80 used mainly for everyday road miles may point a buyer toward one style of performance radial, while a more aggressive driving focus may lead to another within the same size. It also helps to keep front and rear tire character consistent on a staggered 5.0 setup rather than mixing unrelated designs just because the sizes happen to match.
What sidewall styles are available for 2017 Genesis G80 tires?
The available 2017 Genesis G80 tires in these sizes use blackwall sidewalls. That applies across the 245/45R18, 245/40R19, and 275/35R19 fitments, including the BFGoodrich g-Force family and Nitto NT555 G2 where offered.
Since sidewall appearance is consistent here, the real comparison shifts to series character, rim-width compatibility, and load specification. For a modern luxury sport sedan like the G80, blackwall presentation also keeps the look clean and contemporary, so the buying decision is more about selecting the right performance-oriented radial within the correct size and position.
What brands offer tires for the 2017 Genesis G80?
BFGoodrich and Nitto offer tires for the 2017 Genesis G80 within the applicable sizes on this page. Depending on the exact size, available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2.
Brand alone should not decide the purchase. Compare the exact size, the wheel position on staggered 5.0 cars, the approved rim-width range, and any stated load figure that matters to your setup. Looking at the series side by side is the best way to narrow the choices once the correct 18-inch or 19-inch fitment has been confirmed.
Restoration & Appearance
Does correct tire fitment matter for a 2017 Genesis G80 restoration or preservation project?
Yes, correct tire fitment still matters on a 2017 Genesis G80 even though it is a modern car rather than a traditional restoration-era vehicle. Using the proper 245/45R18 size on the 3.8 or the correct 245/40R19 front and 275/35R19 rear sizes on the 5.0 helps preserve the car's intended stance and wheel-to-tire balance.
Preservation-minded owners should pay close attention to whether the car remains on its original wheel diameter and staggered or non-staggered layout. A used G80 may already have aftermarket wheels or replacement tires installed, so checking what is actually on the vehicle is just as important as knowing the proper size for the model configuration.
Which tire should I choose for a clean, period-appropriate look on a 2017 Genesis G80?
A clean, period-appropriate look for a 2017 Genesis G80 starts with staying in the correct original-style size format for the car's sub-model and wheel position. The available tires in these fitments are blackwall radials, which suit the G80's modern luxury-sport appearance better than a more decorative sidewall treatment would.
After size is confirmed, compare the available series with an eye toward preserving the sedan's balanced visual proportion rather than chasing the most aggressive look possible. Oversized substitutions or mismatched front and rear fitments can change the appearance quickly, especially on the 5.0, so staying close to the intended staggered layout usually produces the most natural result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Genesis G80?
Yes, modifications can affect tire fitment on a 2017 Genesis G80. Aftermarket wheels, different wheel widths, suspension changes, lowering, or altered alignment settings can all change how a 245/45R18, 245/40R19, or 275/35R19 tire sits in the wheelwell and how much clearance remains during steering and suspension travel.
A modified car should be checked carefully before replacement tires are chosen. Confirm actual wheel diameter and width, then look at fender clearance, inner clearance, and front-to-rear positioning on staggered 5.0 setups. Even when the size code seems familiar, wheel changes can make a tire that suits one G80 layout a poor match for another.
What should I inspect before driving a 2017 Genesis G80 on new tires?
Before driving a 2017 Genesis G80 on new tires, inspect the wheels for damage, confirm the correct tire size at each position, and verify proper inflation. It also helps to check for uneven wear patterns from the previous set, since they may point to alignment or suspension issues that could shorten the life of the replacement tires.
Road-use readiness goes beyond mounting fresh rubber. Look over brake and suspension condition, make sure lug hardware is correct and properly tightened, and confirm that a 5.0 still has the proper front-to-rear tire placement. A short local drive followed by a recheck of pressure and visual clearance is a sensible way to catch problems early.
How often should tires on a 2017 Genesis G80 be inspected?
Tires on a 2017 Genesis G80 should be inspected regularly, not just when tread looks low. Pressure, tread wear, sidewall condition, and any sign of cuts, bulges, or irregular wear deserve routine attention, especially on the 5.0 where a staggered setup can hide developing issues if only one axle is checked closely.
Monthly visual checks are a smart habit, and any vibration, pull, or sudden change in road feel deserves immediate attention. Cars that spend long periods parked still need tire inspection because age, heat, and flat-spotting can become issues even with limited mileage. Keeping records of pressure checks and rotations, where applicable, makes wear trends easier to catch.
