2022 Infiniti Tire Fitment Guide

2022 Infiniti fitment here covers two model lines with six distinct sizes. The Q50 uses 225/50R18, 245/40R19, and 265/35R19, while the Q60 uses 255/40R19, 255/35R20, and 275/30R20. Rim diameters span 18, 19, and 20 inches, and rim width guidance appears on several sizes: 225/50R18 fits 6.0 to 8.0-inch rims, 245/40R19 fits 8.0 to 9.5-inch rims, 265/35R19 fits 9.0 to 10.5-inch rims, 255/40R19 fits 8.5 to 10.0-inch rims, and 255/35R20 fits 8.5 to 10.0-inch rims.

That means 2022 Infiniti buyers should start with model identification, then confirm the wheel diameter already on the car. A Q50 and Q60 do not share a universal replacement size, and even within one model, different wheel packages point to different tire dimensions. Matching the exact size on the sidewall or factory wheel package is the safest way to stay within the intended fitment family.

On a 2022 Infiniti, 225/50R18 is a metric radial tire size. The 225 is the nominal section width in millimeters, 50 is the aspect ratio, meaning the sidewall height is 50 percent of that width, R indicates radial construction, and 18 is the wheel diameter in inches. In this application, 225/50R18 belongs to the Q50 and is paired with 18-inch wheels.

That code matters because each part affects the tire’s overall dimensions and wheel compatibility. A tire with the same 18-inch rim diameter but a different width or aspect ratio can change stance, clearance, and speedometer behavior. For a Q50 owner, 225/50R18 points to the standard 18-inch fitment family rather than the lower-profile 19-inch alternatives used elsewhere in the range.

No, 2022 Infiniti models do not use the same tire size across the lineup. The Q50 uses one 18-inch size and two 19-inch sizes, while the Q60 uses one 19-inch size and two 20-inch sizes. Every fitment here is a radial, but the actual dimensions and wheel diameters differ from model to model.

That difference is important for buyers who know they have a 2022 Infiniti but have not yet narrowed it down to Q50 or Q60. The body style and wheel package determine the tire family, and that affects both fitment and available product choices. If the car has been modified, check the wheel itself and the current sidewall marking before using model-level fitment as your final reference.

2022 Infiniti tire options in these sizes use Blackwall sidewalls throughout the range. That applies to Q50 sizes such as 225/50R18, 245/40R19, and 265/35R19, as well as Q60 sizes such as 255/40R19, 255/35R20, and 275/30R20. The overall look is contemporary and consistent with the modern sport-luxury character of these cars.

For a 2022 Infiniti owner, that keeps the decision focused on correct size, brand, and speed rating rather than decorative sidewall treatment. Unlike earlier collector vehicles where whitewalls or period sidewall scripts may influence authenticity, these late-model Infiniti applications are centered on clean modern presentation. Choosing the right size and load-speed specification will matter more than sidewall styling on this year and make.

BFGoodrich and Nitto cover the 2022 Infiniti sizes here. BFGoodrich appears across 225/50R18, 245/40R19, 265/35R19, 255/40R19, and 255/35R20, while Nitto appears in 265/35R19, 255/35R20, and 275/30R20. That gives Q50 buyers BFGoodrich-only coverage in some sizes and a BFGoodrich-Nitto choice in 265/35R19, while Q60 buyers see BFGoodrich in 255/40R19, BFGoodrich and Nitto in 255/35R20, and Nitto in 275/30R20.

The practical takeaway is that brand choice depends partly on which wheel package your 2022 Infiniti carries. A common-size performance application may open up multiple brand paths, while a more specialized rear fitment can narrow the field. Once size is confirmed, compare the available series within that size for speed rating, load capacity, and approved rim-width range rather than assuming every brand offers the same specification.

On several 2022 Infiniti sizes, BFGoodrich g-Force Phenom T/A and g-Force Sport COMP-2 overlap but are not identical. In 245/40R19, the g-Force Sport COMP-2 carries a 98W rating while the g-Force Phenom T/A carries a 98Y rating, and both fit 19-inch rims with an 8.0 to 9.5-inch approved width range. In 255/35R20, the g-Force Sport COMP-2 is 97W while the g-Force Phenom T/A is 97Y, and the Phenom T/A also carries a 1609-pound load figure at 50 psi.

That means two tires in the same size can differ in speed category and supporting specification even when they appear very similar at a glance. For a 2022 Infiniti owner, it is worth comparing the exact sidewall marking and approved rim-width range before making a final choice. The better match is the one that aligns with your wheel width, intended driving use, and the car’s original fitment size.

Several 2022 Infiniti sizes have clear rim-width guidance. 225/50R18 fits 6.0 to 8.0-inch rims, 245/40R19 fits 8.0 to 9.5-inch rims, 265/35R19 fits 9.0 to 10.5-inch rims, 255/40R19 fits 8.5 to 10.0-inch rims, and 255/35R20 fits 8.5 to 10.0-inch rims. Those ranges are size-specific, so they should not be transferred from one tire size to another just because the wheel diameter is similar.

That is especially important on 2022 Infiniti applications because the cars use low-profile performance sizes where section width and wheel width work closely together. Before ordering, confirm the actual wheel width stamped on the wheel or verify it through the vehicle’s wheel specification. Staying within the approved rim-width range helps maintain the intended tire shape, load support, and overall fitment behavior.

The 2022 Infiniti tires in these sizes are tubeless radial applications. Product markings include TL on one 255/40R19 example, and the modern ZR radial construction used across the full fitment range aligns with tubeless performance tires rather than tube-type collector-car casings. Nothing in these Q50 and Q60 sizes points to a tube-type setup.

For most owners, that means the focus shifts to wheel condition, valve stems, and bead-sealing surfaces rather than tube selection. If the car is on factory-style late-model wheels, tubeless fitment is the normal expectation. A wheel that has been repaired, refinished, or replaced should still be inspected carefully, since air loss on a tubeless tire often starts with wheel or valve issues rather than the tire itself.

A 2022 Infiniti should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that age rubber. Keep the tires properly inflated, avoid long exposure to standing moisture, and move the car periodically if it will sit for extended periods. These are low-profile radial performance tires, so prolonged underinflation during storage can put extra stress on the sidewall and contact patch.

If the car will remain parked for months, rolling it occasionally or supporting it appropriately can help reduce flat spotting and localized stress. Clean the tires with mild soap and water rather than petroleum-based dressings. A storage routine matters just as much on a modern performance-luxury Infiniti as it does on an older collector car, especially when replacement sizes are exact and profile-sensitive.

Tires on a 2022 Infiniti should be evaluated by age as well as tread wear. A practical collector and enthusiast standard is to inspect closely once tires reach about five to seven years of service and to treat roughly ten years as a serious replacement threshold, even if tread depth still looks usable. The DOT date code on the sidewall is the best way to establish tire age.

That matters because many Q50 and Q60 cars see lower annual mileage than ordinary commuter vehicles, so tread may not disappear before age-related hardening or cracking begins. Heat cycles, storage conditions, and inflation habits can shorten useful life further. A newer-looking tire is not automatically a younger tire, so sidewall date verification should be part of any ownership baseline on a 2022 Infiniti.

Tires on a 2022 Infiniti should be inspected before every drive and again before any longer trip. Look for sidewall cracking, cuts, punctures, uneven wear, tread damage, and any sign of bulging or impact injury, especially on the lower-profile 19- and 20-inch fitments. Pressure should be checked regularly, not just visually, because a low-profile radial can lose pressure without appearing dramatically underinflated at a glance.

That inspection habit is especially worthwhile on performance-luxury cars that may sit between drives and then return to highway use without much warning. A quick pressure and condition check helps catch issues before they affect handling or ride quality. If the car has recently hit a pothole or curb, inspect both the tire and the wheel immediately, since wheel damage can accompany tire damage on short-sidewall applications.

Yes, the 2022 Infiniti tires in these fitments are modern radial highway-capable tires, and their speed ratings support normal interstate use comfortably when the tires are in good condition and properly inflated. W-rated products are rated up to 168 mph, and Y-rated products are rated to 186+ mph. Those ratings appear across sizes such as 245/40R19, 265/35R19, 255/40R19, and 255/35R20, while other sizes such as 225/50R18 and 275/30R20 are available with W ratings.

Real-world safety still depends on more than the letter on the sidewall. Tire age, inflation pressure, alignment, suspension condition, and impact damage all matter, particularly on low-profile performance fitments. On a 2022 Infiniti, the car’s mechanical condition and the exact size match are just as important as the tire’s speed category when preparing for regular highway use.

Inflation pressure for a 2022 Infiniti should start with the factory placard or owner’s manual for the exact model and wheel package, since the car’s recommended running pressure is vehicle-specific. Several tire options also carry their own maximum load and pressure references: 225/50R18 includes 1709 lbs at 50 psi, 245/40R19 and 265/35R19 include 1653 lbs at 50 psi, 255/40R19 includes 1764 lbs at 50 psi, and 255/35R20 includes 1609 lbs at 50 psi.

Those figures are tire capacity limits, not a universal everyday inflation target. They should not be used as a substitute for the vehicle manufacturer’s recommendation, and they should not be transferred from one size to another. For the best result, use the Infiniti-specified pressure for your exact Q50 or Q60 fitment, then confirm the tire’s sidewall information for its maximum rated pressure and load ceiling.

Before a longer drive in a 2022 Infiniti, inspect each tire for cracking, cuts, punctures, bulges, uneven wear, and any damage from potholes or curb contact. Confirm cold inflation pressure, check that valve stems are intact, and make sure the spare or emergency tire solution is serviceable. On staggered-size applications such as some Q50 and Q60 wheel packages, verify that each tire is mounted in the correct position and matches the intended size.

A longer-trip check should also include the broader condition of the car, especially brakes, alignment, and suspension components that can accelerate tire wear or affect stability. These Infiniti fitments use short sidewalls and performance-oriented dimensions, so small issues can become noticeable quickly at speed. A careful pre-drive routine helps protect both ride quality and tire life on the road.
