The 2015 Hyundai Genesis marked Hyundai’s move deeper into the rear-wheel-drive luxury sport sedan market, blending quiet grand-touring comfort with a more serious performance character than many buyers expected. On this exact model, tire fitment depends on whether the car carries the 3.8 setup or the staggered 5.0 arrangement, with radial sizes in both 18-inch and 19-inch diameters. That makes the real decision less about vintage-style construction and more about matching the correct wheel position, profile, and series. Blackwall performance radials from BFGoodrich and Nitto give the Genesis owner room to balance everyday road use, sharper response, and the overall look of the car.
Which Tire Size Is Right for The 2015 Hyundai Genesis
The 2015 Hyundai Genesis uses three primary tire sizes, and the right one depends first on the exact sub-model and wheel position. The 3.8 uses an 18-inch radial, while the 5.0 uses a staggered 19-inch setup with one size for the front and a wider size for the rear. Before choosing a tire, confirm whether the car is a 3.8 or 5.0 and verify the actual rim diameter on the vehicle, especially if wheels have been changed.
A 245/45R18 tire is a metric radial size with a 245-millimeter nominal section width, a 45-series profile, and an 18-inch rim diameter. On the 2015 Hyundai Genesis, this size belongs to the 3.8 and keeps the fitment in a modern radial construction suited to contemporary handling and touring use. Available choices include BFGoodrich and Nitto options in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2, all in Blackwall styling. This is the size to evaluate when the car has the 3.8 wheel package and you want to compare road manners, load specification, and rim-width compatibility within the correct format.
A 245/40R19 tire uses the same 245-millimeter nominal width as the 18-inch option, but with a shorter 40-series profile and a 19-inch rim diameter. On the 2015 Hyundai Genesis, this size is used at the front of the 5.0, where it forms part of the staggered factory-style layout rather than a square four-corner setup. BFGoodrich offers this size in Blackwall form across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. Choose this size only when the Genesis has the 5.0 front-wheel fitment and confirm that the front wheels are still 19-inch rims before comparing product details.
A 275/35R19 tire is a wider metric radial with a 275-millimeter nominal section width, a 35-series profile, and a 19-inch rim diameter. On the 2015 Hyundai Genesis, this size is used at the rear of the 5.0, making it the wider half of the car’s staggered 19-inch arrangement. Product choices include Blackwall performance radials 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 rear size to assess when maintaining the proper front-to-rear balance on a 5.0 equipped with its original-style wheel layout.
Sub-model fitment matters on the 2015 Hyundai Genesis because the tire setup changes between the 3.8 and the 5.0. The 3.8 uses one 18-inch size, while the 5.0 uses a staggered 19-inch front and rear combination, so identifying the exact configuration comes first.

2015 Hyundai Genesis 3.8
The 2015 Hyundai Genesis 3.8 uses a single 245/45R18 radial size, which makes fitment more straightforward than the staggered 5.0 arrangement. Tire selection here centers on choosing among available Blackwall performance radial series, along with confirming the car still carries the correct 18-inch wheels.
The front position on the 2015 Hyundai Genesis 5.0 uses a 245/40R19 radial, and that size works as part of a staggered setup rather than as a universal fitment for every corner. Tire selection should preserve the intended front fitment and begin with confirming the 19-inch front wheel size.
The rear position on the 2015 Hyundai Genesis 5.0 uses a wider 275/35R19 radial, giving the car a distinct rear fitment compared with the front. Choosing a rear tire means keeping the staggered layout intact and comparing series, rim-width suitability, and overall vehicle setup before mixing products.
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 2015 Hyundai Genesis Tires for Sale
Available 2015 Hyundai Genesis tires center on modern Blackwall radial performance options from BFGoodrich and Nitto. Across the 18-inch and 19-inch sizes, the main comparisons come down to tire series, rim-width compatibility, load specifications where stated, and whether the car uses the single-size 3.8 setup or the staggered 5.0 layout.
The most common 2015 Hyundai Genesis tire questions revolve around identifying the correct size for the 3.8 or 5.0, confirming 18-inch versus 19-inch wheels, and choosing among the available radial performance tire series for everyday road use and proper staggered fitment.
Tire Size & Fitment
What tire size fits a 2015 Hyundai Genesis?
The 2015 Hyundai Genesis uses three primary tire sizes depending on sub-model and wheel position. The Genesis 3.8 uses 245/45R18, while the Genesis 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 first step is confirming whether the car is a 3.8 or a 5.0, then checking whether the car still has its original wheel arrangement. A 5.0 needs the correct front and rear sizes matched to their positions, while a 3.8 uses one size. If the Genesis has aftermarket wheels, measure the actual rim diameter before choosing a tire.
What size rim does a 2015 Hyundai Genesis use?
The 2015 Hyundai Genesis uses either an 18-inch or 19-inch rim depending on configuration. The 3.8 uses an 18-inch rim with 245/45R18 tires, while the 5.0 uses 19-inch rims with 245/40R19 tires in front and 275/35R19 tires in the rear.
Rim diameter is the most important fitment check before ordering tires because an 18-inch tire cannot be mounted on a 19-inch wheel, and vice versa. On a used Genesis, wheel changes are always possible, so it is smart to verify the stamping on the wheel or the current tire size on the car rather than relying only on the badge.
Why does the 2015 Hyundai Genesis have more than one tire size?
The 2015 Hyundai Genesis has more than one tire size because tire fitment changes by sub-model, and the 5.0 also uses a staggered setup. The 3.8 uses 245/45R18, while the 5.0 splits its fitment between 245/40R19 front tires and wider 275/35R19 rear tires.
That means tire selection is tied to the exact wheel package on the car, not just the model name. A staggered setup should keep the correct front and rear positions matched, while the 3.8 is simpler because it uses one size. Verifying the sub-model and actual wheel diameter helps avoid ordering a tire meant for a different Genesis configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Hyundai Genesis?
Start with the correct size for the exact car: 245/45R18 for the 3.8, or 245/40R19 front and 275/35R19 rear for the 5.0. From there, compare radial tire series, stated load figures where available, rim-width compatibility, and whether the tire’s overall character suits everyday road use or a more performance-focused setup.
The available Genesis options include BFGoodrich and Nitto products, all in Blackwall styling, so the main differences are series and specification rather than sidewall appearance. It also helps to keep the vehicle’s current wheel setup in mind. Matching the right tire to the right rim width and axle position matters more than choosing purely by brand name.
What brands offer tires for the 2015 Hyundai Genesis?
BFGoodrich and Nitto both offer tires for the 2015 Hyundai Genesis in the sizes used on this model. Depending on the size, the available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2.
Brand choice should be treated as one part of the decision rather than the whole decision. It still makes sense to compare each tire by size, intended wheel position, rim-width range, and other specifications tied to the exact product. On the 5.0 especially, make sure front and rear selections maintain the proper staggered fitment before comparing brand preferences.
What tire series are available for the 2015 Hyundai Genesis?
The 2015 Hyundai Genesis is covered by several modern radial 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. Availability varies by the exact Genesis tire size, so the right series depends on whether the car uses the 18-inch or staggered 19-inch setup.
Series names help separate the product choices in the grid, but size and wheel position still come first. A 3.8 owner can compare options within 245/45R18, while a 5.0 owner needs to compare the front and rear sizes separately. Looking at each series alongside rim-width specifications and load information creates a more useful comparison than name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Hyundai Genesis?
Yes, modifications can affect tire fitment on a 2015 Hyundai Genesis even when the tire size looks close to stock. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, and body or fender alterations can all change how a 245/45R18, 245/40R19, or 275/35R19 tire sits on the car.
That is especially important on the 5.0 because the front and rear tires are different sizes and are meant for specific wheel positions. A Genesis with non-original wheels should be checked for actual rim diameter, width, and clearance at full steering lock and full suspension travel. Small setup changes can matter just as much as the tire size itself.
What should I inspect before driving a 2015 Hyundai Genesis on new tires?
Before driving a 2015 Hyundai Genesis on new tires, inspect the wheels for damage, confirm the tire size matches the correct sub-model or axle position, and verify that each tire is mounted on the proper rim diameter. Tire pressure should be set correctly, and the suspension and alignment should be in sound condition.
A quick visual check also helps catch avoidable problems such as rubbing, uneven wheel spacing, or a rear tire mounted where a front tire belongs on a staggered 5.0 setup. After the first miles, recheck pressures and look for any signs of unusual wear or contact. Those simple steps help the new tires settle into service properly.
What should I check before a longer drive in a 2015 Hyundai Genesis?
Before a longer drive in a 2015 Hyundai Genesis, check inflation pressure, tread and sidewall condition, and any signs of cuts, bulges, or air loss. It also makes sense to confirm that the car has the correct size at each position, especially on a 5.0 where the front and rear tires are intentionally different.
Longer highway use places more importance on basic tire condition than many occasional drivers realize. A Genesis that has sat for extended periods should have its tires inspected for age-related cracking and flat spotting before being driven hard. Taking a moment to verify wheel torque, alignment feel, and general clearance can prevent problems once the trip begins.
