The 2015 Hyundai Equus was Hyundai’s full-size flagship sedan, aimed at buyers who wanted substantial comfort, quiet road manners, and rear-drive luxury in a modern executive-car format. Its long-wheelbase presence and upscale mission make tire fitment especially important, because the chassis relies on a staggered 19-inch setup rather than a one-size arrangement. The front uses 245/45R19 radial tires, while the rear uses 275/40R19 radials. Available choices center on blackwall performance-oriented radial lines from BFGoodrich and Nitto. For an Equus owner, the key is matching the correct front and rear sizes, then choosing the tire series that best suits the car’s road use and wheel setup.
Which Tire Size Is Right for The 2015 Hyundai Equus
The 2015 Hyundai Equus uses two primary tire sizes, both in metric radial construction on 19-inch rims. Tire selection depends on position, because the front uses 245/45R19 and the rear uses 275/40R19 across the covered Signature and Ultimate configurations. The first step is confirming that the car still has its correct staggered wheel setup before choosing among the available radial tire lines.
245/45R19 is a 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 rim diameter in inches. On the 2015 Hyundai Equus, this size serves the front position in the staggered setup. 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 size matters because it preserves the intended front fitment, so wheel width and front-end clearance should be checked before substituting anything else.
275/40R19 is a metric radial size with a 275-millimeter nominal section width, a 40-series profile, radial construction, and a 19-inch rim diameter. On the 2015 Hyundai Equus, this is the rear tire size and works with the wider rear wheel position in the staggered arrangement. BFGoodrich and Nitto options are available here as well, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2, all in blackwall form. Choosing this size correctly helps maintain the front-to-rear fitment balance, especially if the car has seen wheel or suspension changes.
Sub-model fitment on the 2015 Hyundai Equus is straightforward in one way and position-sensitive in another. Signature and Ultimate both use the same staggered 19-inch tire setup, so the important distinction is front versus rear rather than trim level.

2015 Hyundai Equus Signature Front
The Signature front position uses the 245/45R19 radial size. Tire selection here centers on choosing the right blackwall radial series for the front axle while keeping wheel width and overall front-end fitment in mind.
The Signature rear position uses the wider 275/40R19 radial size. That makes rear tire choice a matter of matching the correct staggered fitment and confirming compatibility if the car no longer has its original wheel arrangement.
The Ultimate front position uses the same 245/45R19 radial tire size as the Signature front. That keeps trim-level fitment simple, leaving the real decision focused on tire series, wheel compatibility, and intended driving use.
The Ultimate rear position uses 275/40R19 radial tires, matching the Signature rear setup. For selection purposes, the key is retaining the proper rear size and checking wheel width and clearance if any modifications have been made.
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 Equus Tires for Sale
Available 2015 Hyundai Equus tire options focus on the 245/45R19 front and 275/40R19 rear sizes, with blackwall radial choices from BFGoodrich and Nitto. The main differences in the product grid come from tire series, rim-width compatibility, load-related specifications, and overall performance-oriented character.
Common 2015 Hyundai Equus tire questions usually come down to the staggered front-and-rear sizing, 19-inch rim fitment, product-series differences, and what to inspect before putting a full-size luxury sedan back on the road.
Tire Size & Fitment
What tire size fits a 2015 Hyundai Equus?
The 2015 Hyundai Equus uses a staggered tire setup with 245/45R19 on the front and 275/40R19 on the rear. Both sizes are radial tires fitted to 19-inch rims, and this front-to-rear arrangement applies to the covered Signature and Ultimate configurations.
That means the first fitment check is tire position, not just trim level. An Equus with replacement wheels, a previous tire swap, or mixed-size service history should be inspected carefully so the front and rear sizes are not reversed and the wheel widths still match the intended staggered setup.
What size rim does a 2015 Hyundai Equus use?
Both primary tire sizes for the 2015 Hyundai Equus are built around a 19-inch rim diameter. The front 245/45R19 and rear 275/40R19 sizes share that diameter, even though the rear tire is wider and lower in profile than the front.
Rim diameter is only part of the fitment picture, so the actual wheel width still matters when comparing tires. A car that has been fitted with aftermarket wheels should be checked for both diameter and width before any replacement tire is chosen, especially because the Equus uses different front and rear sizes.
Do all 2015 Hyundai Equus sub-models use the same tire size?
The covered 2015 Hyundai Equus sub-models share the same overall tire arrangement rather than one identical size at all four corners. Signature and Ultimate both use 245/45R19 on the front and 275/40R19 on the rear, so trim level does not change the basic fitment pattern.
That makes the real question front versus rear, not Signature versus Ultimate. Tire selection stays simpler when the original staggered layout is still in place, but any wheel change, rotation mistake, or previous owner modification should be verified before ordering replacements for a specific corner of the car.
Choosing the Right Tire
What should I consider when choosing a 2015 Hyundai Equus tire?
Start with the correct position-specific size, since the 2015 Hyundai Equus uses 245/45R19 in front and 275/40R19 in the rear. From there, compare radial tire series, wheel-width compatibility where stated, load-related specifications, and whether the car is being driven as a luxury cruiser, a highway car, or a more aggressively tuned street sedan.
An Equus owner should also think about keeping the front and rear tire character consistent. Mixing very different tire types across a staggered setup can change the way the car feels on the road, so it helps to confirm wheel dimensions, match the correct size to each axle, and choose a tire line that suits the car’s intended use.
What brands offer tires for the 2015 Hyundai Equus?
Tire options for the 2015 Hyundai Equus include BFGoodrich and Nitto in the correct 19-inch front and rear sizes. Across the two sizes, BFGoodrich appears in several g-Force series and the g-Force Phenom T/A line, while Nitto offers the NT555 G2.
Brand choice is only one part of the decision, because the available tires also vary by series and some published wheel-width specifications. The better approach is to choose the correct front or rear size first, then compare the specific tire line that fits the car’s wheels and the kind of driving the Equus actually sees.
What tire series are available for the 2015 Hyundai Equus?
The 2015 Hyundai Equus has several available tire series in its correct sizes, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. These are all radial blackwall options sized for the Equus front or rear fitment.
Series choice helps distinguish one tire from another when the size is already correct. It is worth comparing which line applies to the front size, which applies to the rear size, and whether the wheel-width range and other product details make sense for the actual wheel setup on the car before making a final selection.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Hyundai Equus?
A period-style approach for a 2015 Hyundai Equus starts with keeping the original staggered layout intact: 245/45R19 in front and 275/40R19 in the rear. Since the available options are modern radial blackwall tires, the decision is less about vintage appearance and more about preserving the sedan’s proper visual stance and factory-era sizing character.
That usually means avoiding experimental size changes that alter the Equus’s balanced executive-sedan presentation. Owners focused on a clean, era-appropriate look should compare tire series within the correct sizes, confirm the wheels remain true to the intended setup, and keep front and rear fitment consistent from side to side.
Does correct tire fitment matter for a 2015 Hyundai Equus restoration?
Correct tire fitment matters on a 2015 Hyundai Equus because the car was designed around a staggered 19-inch arrangement rather than a universal four-corner size. Using the proper 245/45R19 front and 275/40R19 rear sizes helps preserve the car’s intended stance, wheel-to-tire proportion, and overall presentation.
Appearance is only part of the story, since incorrect sizing can also complicate wheel clearance and service consistency. A restoration-minded owner should confirm the actual wheels on the car, inspect for previous modifications, and keep the fitment aligned with the original front-and-rear size relationship instead of treating the Equus like a square-setup sedan.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Hyundai Equus?
Yes, modifications can affect tire fitment on a 2015 Hyundai Equus even when the nominal tire sizes remain 245/45R19 front and 275/40R19 rear. Aftermarket wheels, suspension changes, lowering, or bodywork differences can alter the wheel width, offset, and available clearance around the wider rear tire especially.
That is why a modified Equus should be measured rather than assumed correct by size alone. Checking wheel dimensions, steering clearance, fender clearance, and the relationship between the tire and suspension components helps prevent choosing a tire that matches the size code but does not suit the actual setup now on the car.
What should I inspect before driving a 2015 Hyundai Equus on new tires?
Before driving a 2015 Hyundai Equus on new tires, inspect the wheel condition, confirm the front and rear sizes are mounted in the correct positions, and check inflation carefully. It also makes sense to look over alignment condition, valve stems, and any signs of rubbing that might point to a wheel or suspension issue.
A full-size luxury sedan puts a lot of emphasis on smooth road manners, so small setup issues can become noticeable quickly. After installation, recheck pressure, monitor for vibration, and look for uneven wear during the first stretch of use so any fitment or chassis problem is caught before it becomes a bigger issue.
How often should tires on a 2015 Hyundai Equus be inspected?
Tires on a 2015 Hyundai Equus should be inspected regularly, not just when tread looks worn. A quick visual check for air loss, cuts, bulges, punctures, shoulder wear, and sidewall damage is worthwhile during routine use, and a more deliberate inspection should happen before longer trips or after the car has been parked for extended periods.
The Equus uses a staggered setup, so inspection also means confirming that each axle still carries the correct size. Paying attention to pressure consistency and wear patterns can reveal alignment or suspension issues early, which is especially useful on a heavier executive sedan where tire condition has a strong effect on comfort and stability.
