2016 Infiniti Q50 Tires

The 2016 Infiniti Q50 uses three primary radial tire sizes: 225/55R17, 245/40R19, and 265/35R19. The correct size depends on the sub-model and wheel setup. Base models use 225/55R17, many Hybrid Premium, Sport, and Red Sport 400 AWD versions use 245/40R19, and the Red Sport 400 RWD uses a staggered arrangement with 245/40R19 in front and 265/35R19 in the rear.

The practical first step is checking the exact trim and the wheels already on the car. Premium models can appear with either 17-inch or 19-inch fitment, and the Red Sport 400 RWD should be checked by axle position instead of assuming the same size at all four corners. Matching the installed wheel diameter is just as important as matching the tire size.

A 2016 Infiniti Q50 uses either a 17-inch or 19-inch rim, depending on the tire size and sub-model. The 225/55R17 fitment uses a 17-inch rim, while both 245/40R19 and 265/35R19 use 19-inch rims. That means the vehicle spans two wheel diameters across the covered configurations rather than one universal rim size.

Rim diameter should be confirmed before comparing any tire options, especially on a Premium model that may have either package. On a Red Sport 400 RWD, the wheel diameter stays at 19 inches front and rear, but the tire sizes still differ by axle. A quick sidewall check on the current tires usually settles the question before ordering replacements.

The 2016 Infiniti Q50 has more than one tire size because fitment changes with trim, wheel package, drivetrain configuration, and in one case front-versus-rear placement. Some versions use 225/55R17 on 17-inch wheels, several performance-oriented configurations use 245/40R19 on 19-inch wheels, and the Red Sport 400 RWD adds a wider 265/35R19 rear tire as part of a staggered setup.

That variation means tire selection starts with identifying the exact version of the car rather than searching the model name alone. It is also worth checking whether the car still wears its original wheel package, since later owner changes can alter what is physically on the vehicle. Using the current tire sidewall markings is the safest confirmation point.

For a 2016 Infiniti Q50 that uses 245/40R19, start with the correct sub-model and make sure the car actually has a 19-inch square setup. Available options in this size are radial blackwall tires from BFGoodrich, including the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. That gives you a choice of tire series within the same primary fitment.

The next comparison points are wheel compatibility and how you want to use the car. This size is used across several trims, but that does not make every 19-inch setup identical if aftermarket wheels have been installed. Check the wheel width, compare any load information that matters to your application, and keep the same size at all four corners unless the car uses a factory-style staggered arrangement.

Sidewall style depends on the tire size chosen for the 2016 Infiniti Q50. Blackwall is available across all three primary sizes, while 225/55R17 also offers appearance-focused choices in wide whitewall and redline through the Silvertown Radial line. The 19-inch 245/40R19 and 265/35R19 options shown here are blackwall performance tires.

That means sidewall appearance becomes a bigger factor on 17-inch Q50s than on the 19-inch performance fitments. A buyer trying to preserve a clean modern look may stay with blackwall, while a custom or more personalized build may lean toward the whitewall or redline presentation in 225/55R17. The key is choosing the style within the correct size already used by the car.

BFGoodrich supplies tires for all three 2016 Infiniti Q50 fitments covered here, and Nitto appears in the 265/35R19 rear size. Within BFGoodrich, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Silvertown Radial. Brand choice is therefore tied closely to the specific tire size and whether the car uses a front-only or rear-only staggered fitment.

The most useful way to compare brands is after the correct size has been confirmed. A Base or 17-inch Premium car has a different mix of options than a Red Sport 400 RWD rear axle. Once size is settled, compare the available series, sidewall style, and any wheel-width or load details that matter to how the car is driven and presented.

A period-style direction on a 2016 Infiniti Q50 starts with keeping the correct original-size fitment for the sub-model and wheel package already on the car. Among the available choices, 225/55R17 offers the widest appearance range thanks to Silvertown Radial options, while the 19-inch sizes focus on modern blackwall performance styling. That gives the 17-inch setup more visual flexibility than the 19-inch performance fitments.

The right answer depends on whether the goal is a clean stock-inspired look or a more custom presentation. Whitewall and redline treatments can change the car's character without changing the primary size, but appearance should still come second to correct rim diameter and proper fitment. For owners pursuing exact showroom-era details, model-specific photos and enthusiast references are worth reviewing before making a final choice.

Tire construction is simple on the 2016 Infiniti Q50 because all primary fitments here are radial. That means the visual difference comes less from bias-ply versus radial construction and more from the sidewall treatment and tire series you choose. In practice, blackwall creates the most contemporary performance look, while 225/55R17 also opens the door to wide whitewall or redline styling.

Appearance changes most noticeably when wheel diameter and sidewall profile also change, so it helps to keep the car's intended setup in mind. A 17-inch car with a taller sidewall presents differently from a 19-inch sport package even before the sidewall style is considered. Matching the tire to the wheel package already on the vehicle usually produces the most coherent finished result.

Yes, modifications can affect tire fitment on a 2016 Infiniti Q50 even when the nominal tire size looks correct. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, and body alterations can all change how a 225/55R17, 245/40R19, or 265/35R19 tire sits in the wheelwell. That matters even more on the Red Sport 400 RWD because its staggered layout already uses different front and rear sizes.

A modified Q50 should be checked for steering clearance, fender clearance, and rear-suspension space before replacement tires are chosen. It also helps to confirm whether the car still uses the same wheel diameters as its original setup, since Premium trims can be found on either 17-inch or 19-inch packages. Looking at the current wheel and tire combination avoids ordering by trim name alone.

Before driving a 2016 Infiniti Q50 on new tires, inspect the wheel condition, confirm the tire size matches the car's actual wheel package, and make sure the tires are mounted in the correct positions if the car uses a staggered setup. Tire pressure should be set appropriately, and each tire should be checked for any shipping or installation damage, unusual bulges, or air loss after mounting.

A short initial road test is useful for catching vibration, rubbing, or steering issues before normal use. It also makes sense to recheck lug torque, look for clearance at full steering lock, and confirm that front and rear tires were not mixed on a Red Sport 400 RWD. Those quick checks matter more than brand choice once the correct size has been selected.

Tires on a 2016 Infiniti Q50 should be inspected regularly, not only when tread looks worn. Routine checks should include pressure, visible tread wear, sidewall condition, cuts, punctures, and any signs of uneven wear that could suggest alignment or suspension issues. A performance-oriented sedan with 19-inch low-profile tires can show road-impact damage or edge wear sooner than a taller-sidewall setup.

It helps to inspect the tires before longer drives and anytime the car has been parked for an extended period. Owners should also pay attention to vibration, pulling, or repeated pressure loss, since those symptoms often appear before damage is obvious from a quick walkaround. On a staggered Red Sport 400 RWD, checking front and rear tires separately is especially important because the sizes are different.
