The 2021 Infiniti Q60 sits in the modern sport coupe category with sleek styling, rear-drive performance roots, and a strong appeal for owners who want a grand touring car with sharper visual attitude. Tire choice matters on this model because fitment changes across the lineup, with 255/40R19 on Luxe and Pure models and a 20-inch staggered setup on Red Sport 400 versions. That means the decision is not only about brand, but also about wheel diameter, front-to-rear sizing, and whether blackwall, raised white letter, redline, or performance-oriented series best suit the car. Getting the right size first helps preserve both stance and proper clearance.
Which Tire Size Is Right for The 2021 Infiniti Q60
The 2021 Infiniti Q60 uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel setup. Luxe and Pure models use a 19-inch radial, while Red Sport 400 versions move to 20-inch radials, including a staggered front-and-rear arrangement on the RWD model. Before choosing a tire, confirm the sub-model and wheel diameter, then match the correct front or rear size where staggered fitment applies.
A 255/40R19 tire uses a 255-millimeter section width, a 40-series profile, radial construction, and a 19-inch rim diameter. On the 2021 Infiniti Q60, this size is the primary fitment for Luxe and Pure models, making it the starting point for owners with the standard 19-inch wheel package. Available choices include BFGoodrich and Pro-Trac products in blackwall, raised white letter, and redline presentations across series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Street Pro III. This size is the right place to focus if the car retains its 19-inch setup and a square fitment.
Fit(s): Red Sport 400 (AWD) and Red Sport 400 (RWD) Front
Construction: Radial|Rim: 20 in
A 255/35R20 tire keeps the same 255-millimeter section width but uses a shorter 35-series sidewall on a 20-inch rim. On the 2021 Infiniti Q60, this size is used on Red Sport 400 AWD models and on the front of the Red Sport 400 RWD, so it serves a different role than the 19-inch fitment. Product choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, raised white letter, and redline sidewall treatments available in several performance-oriented series. This is the size to verify when the car has factory-style 20-inch front fitment or an AWD Red Sport 400 configuration.
A 275/30R20 tire is wider than the 255-series options and uses a lower 30-series profile on the same 20-inch rim diameter. On the 2021 Infiniti Q60, this size is used at the rear of the Red Sport 400 RWD, where it forms part of a staggered arrangement rather than a same-size setup at all four corners. The available product choice in this size is a Nitto NT555 G2 blackwall radial, keeping the focus on matching the proper rear application. This size should be selected only after confirming that the car is the RWD Red Sport 400 rear position and not a square setup.
Tire fitment for the 2021 Infiniti Q60 changes by sub-model, and the biggest difference is whether the car uses 19-inch wheels or a 20-inch performance setup. Checking the exact trim and, in the case of the Red Sport 400 RWD, the front or rear position is essential before choosing a tire.

2021 Infiniti Q60 Luxe
The 2021 Infiniti Q60 Luxe uses the 255/40R19 radial size on a 19-inch wheel setup. That keeps tire selection focused on choosing among available brands, sidewall styles, and series rather than sorting through multiple primary fitments.
The 2021 Infiniti Q60 Pure also uses the 255/40R19 radial fitment, matching the standard 19-inch arrangement shared with the Luxe. Tire choice here comes down to construction details, appearance preferences such as blackwall or redline, and confirming the car still has the original wheel diameter.
The 2021 Infiniti Q60 Red Sport 400 (AWD) uses 255/35R20 radial tires on its 20-inch setup. That makes wheel-diameter confirmation especially important, since this fitment differs from the 19-inch Luxe and Pure models and from the staggered RWD arrangement.
The front of the 2021 Infiniti Q60 Red Sport 400 (RWD) uses the 255/35R20 radial size. Front tire selection should stay matched to the rear setup, so the key step is confirming that the tire is being chosen for the front axle of the staggered 20-inch package.
The rear of the 2021 Infiniti Q60 Red Sport 400 (RWD) uses a wider 275/30R20 radial tire. That rear-specific fitment means the tire should be chosen as part of the staggered package, not as a universal Q60 size across all trims or all wheel positions.
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.

Tire Size & Fitment
What tire size fits a 2021 Infiniti Q60?
The 2021 Infiniti Q60 uses three primary tire sizes: 255/40R19, 255/35R20, and 275/30R20. Luxe and Pure models use 255/40R19, the Red Sport 400 AWD uses 255/35R20, and the Red Sport 400 RWD uses a staggered setup with 255/35R20 in front and 275/30R20 in the rear.
That means the correct tire is tied to both sub-model and wheel position. A Q60 owner should confirm the trim level, check whether the car has 19-inch or 20-inch wheels, and make sure a Red Sport 400 RWD is not being treated like a same-size setup at all four corners.
What size rim does a 2021 Infiniti Q60 use?
The 2021 Infiniti Q60 uses either a 19-inch or 20-inch rim, depending on the sub-model. The 255/40R19 fitment uses a 19-inch rim, while the 255/35R20 and 275/30R20 fitments use 20-inch rims.
Rim diameter is the first thing to verify before comparing tires, especially on a Q60 that may have changed wheels since new. Matching the tire to the actual wheel diameter on the car prevents chasing the wrong size and helps keep the fitment process focused on the correct trim and axle position.
Why does the 2021 Infiniti Q60 have more than one tire size?
The 2021 Infiniti Q60 has more than one tire size because the lineup uses different wheel packages and, in the case of the Red Sport 400 RWD, a staggered front-and-rear arrangement. Luxe and Pure models stay with 255/40R19, while Red Sport 400 versions move to 20-inch fitments.
That variation is normal on a performance-oriented coupe with multiple trim levels. The practical takeaway is to identify the exact sub-model first, then confirm whether the car uses a square setup or different front and rear sizes before selecting a tire.
Choosing the Right Tire
What should I consider when choosing a 2021 Infiniti Q60 tire?
Start with the correct Q60 size for the exact trim and wheel position, then compare the available radial tire options within that fitment. Important differences include wheel diameter, whether the car uses a square or staggered setup, sidewall style, tire series, and product details such as load figures or rim-width guidance where available.
A Luxe or Pure owner is choosing within the 255/40R19 category, while a Red Sport 400 owner needs to stay focused on the correct 20-inch front or rear size. Once the fitment is confirmed, appearance and intended use become the deciding factors rather than size alone.
What sidewall styles are available for 2021 Infiniti Q60 tires?
Sidewall choices for the 2021 Infiniti Q60 include blackwall, RWL, and redline, depending on the tire size and series. Blackwall options appear across the BFGoodrich and Nitto performance tires, while Pro-Trac Street Pro III brings raised white letter and redline treatments in select Q60 sizes.
That gives the car noticeably different visual character without changing the primary size itself. Owners who want a more modern understated look often stay with blackwall, while RWL or redline can push the coupe toward a more custom or muscle-inspired appearance, provided the chosen style is available in the exact required size.
What brands offer tires for the 2021 Infiniti Q60?
Tires for the 2021 Infiniti Q60 are available from BFGoodrich, Nitto, and Pro-Trac. Brand availability varies by size, with the 19-inch and front 20-inch fitments offering the broadest mix, while the 275/30R20 rear size for the Red Sport 400 RWD is represented by Nitto in the current selection.
Choosing among brands should start with the correct fitment, then move to series character and sidewall presentation. A driver looking at 255/40R19 or 255/35R20 has more room to compare blackwall, redline, or RWL choices, while the wider rear fitment is more narrowly focused.
Restoration & Appearance
Which tire should I choose for a period-style 2021 Infiniti Q60?
A period-style approach on a 2021 Infiniti Q60 still begins with the proper modern radial size for the exact trim. From there, the most appearance-driven choices are usually within the available sidewall treatments and tire series, especially in 255/40R19 and 255/35R20 where blackwall, raised white letter, and redline options are available.
Because the Q60 is a contemporary performance coupe, period style usually means emphasizing a chosen visual theme rather than recreating an early production presentation. Keeping the original wheel diameter and, where applicable, the proper staggered layout will usually matter more to the overall look than changing to a different size.
How does tire construction affect the appearance of a restored 2021 Infiniti Q60?
Tire construction is straightforward on the 2021 Infiniti Q60 because the primary fitments are all radial. The visible appearance differences come less from construction type and more from profile, wheel diameter, sidewall treatment, and the way a square or staggered setup fills the car's wheel openings.
For an owner refreshing the car's appearance, the main visual choice is usually blackwall versus a more expressive sidewall such as RWL or redline in the correct size. Staying true to the car's original fitment layout helps preserve the intended stance, especially on the Red Sport 400 RWD.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Infiniti Q60?
Yes, modifications can affect tire fitment on a 2021 Infiniti Q60. Aftermarket wheels, altered offsets, suspension changes, ride-height adjustments, or attempts to square up a factory staggered setup can all change how much room the tire has at the fender, suspension, and steering components.
A modified Q60 should have the actual wheel diameter and width checked before a tire is chosen, not just the model year and trim. On Red Sport 400 RWD cars especially, front and rear fitment should be verified separately so a wider rear tire is not mistakenly ordered for the front position.
What should I inspect before driving a 2021 Infiniti Q60 on new tires?
Before driving a 2021 Infiniti Q60 on new tires, inspect the wheels for correct diameter and condition, confirm that each tire size matches the proper axle position, and check inflation pressure carefully. It is also wise to look over alignment condition, valve stems, and any visible suspension or steering issues that could affect tire wear.
A short clearance check is especially important on cars with 20-inch fitments or modified wheels. Turning the steering from lock to lock and looking for rubbing at the fender liner, strut area, or rear wheelhouse can catch problems early before they become wear or handling issues.
How often should tires on a 2021 Infiniti Q60 be inspected?
Tires on a 2021 Infiniti Q60 should be inspected regularly, not only when tread looks worn. Pressure, tread depth, shoulder wear, cuts, punctures, sidewall damage, and irregular wear patterns all deserve routine attention, especially on a performance coupe where fitment and alignment have a strong effect on tire life.
Cars with staggered sizing deserve extra attention because front and rear tires do different jobs and cannot simply be treated as one universal set. A quick visual inspection before longer drives, plus closer checks at service intervals, helps catch wear issues before they affect ride quality or road manners.
