The 2017 Genesis G90 arrived as a flagship luxury sedan aimed at established European competitors, with a quiet, substantial road presence and a chassis tuned for composed highway travel. Its tire fitment reflects that modern full-size luxury-sedan mission with a staggered 19-inch radial setup: 245/45R19 in front and 275/40R19 in the rear. That means the main decision is not whether one size fits all corners, but choosing the right front and rear pairing within the correct dimensions. Available options center on blackwall performance-oriented radial tires from BFGoodrich and Nitto, so owners should match tire choice to wheel position, intended use, and the car’s current wheel setup.
Which Tire Size Is Right for The 2017 Genesis G90
The 2017 Genesis G90 uses two primary tire sizes, both in radial construction on 19-inch rims. Fitment depends on wheel position rather than trim alone, with 245/45R19 used at the front and 275/40R19 at the rear on the covered Premium and Ultimate configurations. The first step is confirming that the car still has its proper staggered 19-inch setup before selecting a front tire, a rear tire, or a matched set.
245/45R19 is a modern metric radial size in which 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. On the 2017 Genesis G90, this size serves the front position and supports the car’s staggered fitment layout. Available choices include BFGoodrich and Nitto blackwall tires across series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when replacing the front pair while preserving the intended front-to-rear balance of the car’s 19-inch setup.
275/40R19 is a modern metric radial size where 275 represents nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2017 Genesis G90, this is the rear tire size and it works with the narrower front tire as part of the staggered arrangement. BFGoodrich and Nitto offer blackwall options here, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the key size to confirm when replacing rear tires or checking whether the car still retains the correct wheel-position fitment.
Tire fitment is consistent across the covered G90 Premium and Ultimate configurations, but it varies by wheel position. Checking the exact front or rear application matters because the G90 uses a staggered 19-inch setup rather than one uniform size at all four corners.

2017 Genesis G90 Premium Front
The 2017 Genesis G90 Premium Front uses the front-size radial fitment within the car’s staggered 19-inch arrangement. Tire selection here should focus on choosing the correct front-position size and comparing blackwall radial options that suit the car’s present wheel and suspension setup.
The 2017 Genesis G90 Premium Rear uses the wider rear tire size that completes the staggered radial setup. That makes rear tire selection a matter of confirming the correct wheel position and choosing among available blackwall radial products in the proper rear dimension.
The 2017 Genesis G90 Ultimate Front uses the same front tire sizing approach as the Premium front position, with radial construction on a 19-inch wheel. The practical decision is selecting the right front tire within that size while keeping the front and rear pairing consistent.
The 2017 Genesis G90 Ultimate Rear uses the same wider rear radial fitment as the Premium rear position. Owners replacing rear tires should confirm wheel position first, then compare the available blackwall radial choices in the proper rear size.
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 questions for a 2017 Genesis G90 usually come down to understanding the staggered front and rear sizes, confirming 19-inch wheel fitment, and choosing between the available radial tire series. The answers below also cover product selection, appearance, maintenance, and what to inspect before regular road use.
Tire Size & Fitment
What tire size fits a 2017 Genesis G90?
The 2017 Genesis G90 uses a staggered tire setup with 245/45R19 at the front and 275/40R19 at the rear. Both sizes are radial tires mounted on 19-inch wheels, and the covered Premium and Ultimate front and rear applications follow that same basic front-to-rear sizing pattern.
That means tire selection starts with confirming wheel position rather than looking for one universal size for all four corners. A buyer should verify whether the car still has its original-style staggered setup, since aftermarket wheel changes or previous tire replacements can alter what is currently installed.
What size rim does a 2017 Genesis G90 use?
The primary tire fitments for the 2017 Genesis G90 are built around 19-inch rims. Both 245/45R19 and 275/40R19 use the same 19-inch rim diameter, even though the front and rear tires differ in section width and aspect ratio as part of the staggered arrangement.
Rim diameter is only one part of fitment, so it is still important to confirm actual wheel width and current wheel configuration before replacing tires. A 19-inch wheel must also be appropriate for the specific front or rear tire size being selected, especially on a car with different tire sizes at each end.
Do all 2017 Genesis G90 sub-models use the same tire size?
The covered 2017 Genesis G90 Premium and Ultimate configurations share the same overall fitment pattern, but they do not use one single tire size at every wheel position. Both use 245/45R19 in front and 275/40R19 in the rear, so the difference is between front and rear rather than between those trims.
That makes the practical step very simple: identify whether the tire being replaced is on the front axle or rear axle. Even when the sub-model is the same, choosing the wrong wheel-position size can upset the intended staggered setup and create avoidable fitment or handling concerns.
Choosing the Right Tire
What should I consider when choosing a 2017 Genesis G90 tire?
Start with the correct wheel-position size: 245/45R19 for the front and 275/40R19 for the rear. From there, compare radial construction details, rim-width compatibility where stated, load-capacity information when available, and the intended character of the tire series offered in each size.
The 2017 Genesis G90 is a large luxury sedan, so it helps to think about how the car is used before choosing among the available options. Some owners may prioritize everyday road manners, while others may focus on a more performance-oriented feel, but the correct size and proper front-to-rear pairing come first.
What sidewall styles are available for 2017 Genesis G90 tires?
The available tires for the 2017 Genesis G90 are offered in blackwall form across both primary sizes. That gives the car a clean modern appearance consistent with contemporary performance and luxury-sedan tire presentation rather than a whitewall, redline, or raised-letter look.
Since sidewall treatment is uniform here, the more meaningful differences come from brand, tire series, and fitment details such as wheel-position size and stated rim-width range. A buyer comparing products for this G90 will usually make the final decision on construction details and series character rather than sidewall appearance.
What brands offer tires for the 2017 Genesis G90?
BFGoodrich and Nitto both offer tires in the primary 19-inch sizes used on the 2017 Genesis G90. Depending on front or rear fitment, the available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2.
Choosing between them is less about brand hierarchy and more about selecting the correct front or rear size, then comparing the specific tire series available in that size. It also helps to review rim-width guidance and load information where listed so the selected tire matches the car’s wheel and usage requirements.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Genesis G90?
A period-style approach for a 2017 Genesis G90 still centers on the proper staggered modern radial sizing, since this sedan belongs to a contemporary luxury era rather than a vintage bias-ply period. The correct starting point is 245/45R19 in front and 275/40R19 in the rear, both on 19-inch rims.
Appearance choices are more restrained here than on older collector vehicles, because the available products are blackwall radials rather than ornamental sidewall designs. Owners pursuing an original-era presentation should keep the staggered proportions intact and avoid mixing wheel-position sizes or changing the car’s visual stance unintentionally.
Does correct tire fitment matter for a 2017 Genesis G90 restoration or preservation project?
Correct tire fitment matters because the 2017 Genesis G90 uses a deliberate front-to-rear size relationship rather than one uniform tire at every corner. Keeping the 245/45R19 front and 275/40R19 rear layout preserves the car’s intended visual balance and maintains the wheel-position fitment it was designed around.
Preservation-minded owners should look beyond simple rim diameter and check that the tires on the car still match the proper front and rear sizes. Even on a newer collector candidate, mismatched replacements or wheel changes can alter appearance and complicate future tire selection more than expected.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Genesis G90?
Yes. A 2017 Genesis G90 can be affected by aftermarket wheels, suspension changes, ride-height alterations, or previous tire substitutions, especially because the car uses a staggered 19-inch setup with one size in front and a different size in the rear. Any of those changes can alter clearance or wheel compatibility.
A smart check includes verifying actual wheel diameter, wheel width, and which size is mounted at each axle before ordering replacements. Steering clearance at the front and inner or outer clearance at the rear both matter, particularly if the car no longer retains its original-style wheel and suspension configuration.
What should I inspect before driving a 2017 Genesis G90 on new tires?
Before regular road use, inspect air pressure, tread seating, visible sidewall condition, valve stems, and the basic front-to-rear tire pairing on the 2017 Genesis G90. It also helps to confirm that the 245/45R19 tires are mounted in front and the 275/40R19 tires are mounted at the rear.
A short initial drive should be followed by another look for uneven clearance, rubbing, or air loss. On a car with recent wheel service or tire replacement, rechecking lug torque, alignment behavior, and any vibration at highway speed can catch a setup issue before it becomes a larger problem.
How often should tires on a 2017 Genesis G90 be inspected?
Tires on a 2017 Genesis G90 should be inspected regularly, not just when tread looks low. Routine checks should include pressure, uneven wear, cuts, bulges, cracking, and any signs that the staggered front and rear sizes have been rotated incorrectly or replaced with mismatched dimensions.
Monthly visual checks are a sensible baseline, with a closer inspection before longer trips or after any impact with road hazards. Because this car relies on different front and rear sizes, catching irregular wear early can also help reveal alignment, inflation, or suspension issues before they shorten tire life.
