2024 Infiniti Q50 Tires

The 2024 Infiniti Q50 uses three primary tire sizes: 225/50R18, 245/40R19, and 265/35R19. Fitment depends on the exact sub-model and wheel setup, with the Luxe using 225/50R18, the Sensory and Red Sport 400 AWD using 245/40R19, and the Red Sport 400 RWD using a staggered setup with 245/40R19 in front and 265/35R19 in the rear.

That means the correct choice starts with confirming more than just the model name. Check the trim level, wheel diameter, and whether the car has a square or staggered arrangement before comparing tires, especially on Red Sport 400 RWD cars where front and rear sizes are not the same.

The 2024 Infiniti Q50 uses either an 18-inch or a 19-inch rim, depending on the sub-model and tire size. The 225/50R18 fitment uses an 18-inch rim, while both 245/40R19 and 265/35R19 use 19-inch rims.

Rim diameter should be verified before anything else if the car has had wheel changes or if the current tire markings are unclear. A Q50 with aftermarket wheels, replacement packages, or mixed sets can easily differ from stock trim fitment, and selecting by model name alone can lead to the wrong tire size.

The 2024 Infiniti Q50 has more than one tire size because fitment changes by trim and wheel package. Some versions use an 18-inch setup, some use a 19-inch square setup, and the Red Sport 400 RWD uses a staggered arrangement with different front and rear sizes.

That variation affects more than appearance. It changes the wheel diameter being used and, on staggered cars, the tire's position on the vehicle. The best approach is to identify the exact sub-model first, then confirm whether the car still has its original wheel setup before choosing a replacement tire.

Start with the correct size for the exact Q50 sub-model, then compare the tire's intended use and specifications within that fitment. On this vehicle, the main variables are 18-inch versus 19-inch wheel diameter, square versus staggered fitment, radial tire series, and certain product details such as rim-width compatibility and max load figures where they are shown.

After size is confirmed, think about how the car is driven. A daily-driven Luxe may lead to a different choice than a Red Sport 400 used more aggressively. It also helps to compare whether the tire remains within the wheel's width range and whether the vehicle still uses its original wheel and suspension setup.

BFGoodrich appears across all three 2024 Infiniti Q50 tire sizes, with several g-Force series options available in 225/50R18 and 245/40R19. In 265/35R19, the rear size used on the Red Sport 400 RWD, both BFGoodrich and Nitto are available.

Brand choice should still come after fitment confirmation. On this Q50, some trims share a size while others do not, and the staggered Red Sport 400 RWD uses a different rear tire than the front. Once the correct size and axle position are settled, brand and series become meaningful comparison points.

Available tire series for the 2024 Infiniti Q50 include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. The 265/35R19 size also includes the Nitto NT555 G2, giving the wider rear Red Sport 400 RWD fitment an additional series choice.

Series matters because it helps distinguish the character of one tire from another even when the size is the same. Once the correct fitment is confirmed, comparing series is a practical way to narrow the field without losing sight of the core requirements of wheel diameter, tire position, and compatibility with the car's current setup.

A period-style approach on a 2024 Infiniti Q50 is less about vintage sidewall treatments and more about preserving the car's original visual balance through the correct size and wheel diameter. That means staying with 225/50R18 on the Luxe, 245/40R19 on the Sensory or Red Sport 400 AWD, and the proper staggered 245/40R19 front and 265/35R19 rear setup on the Red Sport 400 RWD.

All of the available products here use a blackwall presentation, which suits the Q50's modern sport-sedan look. For an owner focused on maintaining the car's intended appearance, matching the original fitment pattern and avoiding an unintended wheel or sidewall profile change will usually matter more than chasing cosmetic variation.

Correct tire fitment still matters on a 2024 Infiniti Q50 even though it is a modern vehicle rather than a vintage restoration candidate. The right size preserves the intended relationship between the wheel, tire profile, and body, and that is especially important on trims that use 19-inch performance fitments or a staggered front-and-rear arrangement.

For a careful preservation-minded owner, the goal is usually to keep the car visually and mechanically consistent with its original configuration. Confirm the trim, wheel diameter, and tire position before replacing anything, and pay close attention if the car has been modified or fitted with wheels that differ from the factory-style setup.

Yes, modifications can affect tire fitment on a 2024 Infiniti Q50 even when the replacement tire matches one of the factory sizes. Aftermarket wheels, altered wheel width, offset changes, suspension lowering, or body modifications can all change how much room the tire has at the fender, strut, and steering components.

That matters most on 19-inch setups and staggered Red Sport 400 RWD cars, where front and rear roles are already different. A modified Q50 should be checked for actual wheel diameter, width, and clearance rather than assuming stock dimensions, especially if the current wheels or stance no longer match original trim configuration.

Before driving a 2024 Infiniti Q50 on new tires, inspect the wheel for damage, confirm the tire size matches the correct trim and axle position, and check that inflation is set properly. It is also smart to look at suspension and steering components for looseness or wear, since those issues can affect how a fresh set of tires behaves on the road.

A short visual check can prevent larger problems. Look for uneven clearance, rubbing marks, abnormal tread contact, or signs that the wheel setup is different from the intended Q50 fitment. On staggered cars, confirm the wider rear size has not been installed where the front size belongs, and vice versa.

Before a longer drive in a 2024 Infiniti Q50, check tire pressure, tread condition, sidewall condition, and any sign of cuts, bulges, or air loss. It also helps to confirm the car is wearing the correct size combination for its trim, particularly if it is a Red Sport 400 RWD with different front and rear tires.

Longer drives put more emphasis on condition than appearance. A Q50 that has sat for extended periods should be checked for age-related deterioration and flat spotting, while a recently modified car should be checked for rubbing under steering and suspension movement. Verifying those basics makes the tire choice more meaningful in real road use.
