The 2018 Infiniti Q60 blends modern grand touring style with the sharp stance expected from a luxury sport coupe, and tire fitment plays a big role in preserving that look and response. On this model, fitment ranges from 255/40R19 on several sub-models to a 20-inch setup on Red Sport versions, including a staggered arrangement on Red Sport (RWD). All primary fitments are radial, with product choices that include blackwall, raised white letter, and redline sidewall treatments across several performance-oriented series. The key is confirming the exact sub-model and wheel diameter first, then choosing the tire style and construction details that suit the car's appearance and intended road use.
Which Tire Size Is Right for The 2018 Infiniti Q60
The 2018 Infiniti Q60 uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel setup. Several Q60 trims use 255/40R19 on 19-inch wheels, while Red Sport versions move to 20-inch fitments, including a staggered front-and-rear arrangement on Red Sport (RWD). Before choosing a tire, confirm both the sub-model and the wheel diameter currently on the car.
255/40R19 is a metric radial size in which 255 refers to the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2018 Infiniti Q60, this size is used on several 19-inch-wheel sub-models and keeps the fitment in the vehicle's primary modern radial format. Available choices include BFGoodrich and Pro-Trac options, with blackwall, raised white letter, and redline sidewall treatments 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 when the car retains its 19-inch factory-style wheel diameter.
255/35R20 is a metric radial size with a 255-millimeter nominal section width, a 35-series profile, and a 20-inch rim diameter. On the 2018 Infiniti Q60, this size serves the 20-inch front fitment used on Red Sport models, so it should not be treated as the universal Q60 size. Tire choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, raised white letter, and redline presentations available depending on the series. This is the size to evaluate when the car has the correct 20-inch front-wheel setup and the goal is to match the intended Red Sport fitment.
275/30R20 is a metric radial size in which 275 denotes the nominal section width in millimeters, 30 is the aspect ratio, and 20 is the rim diameter in inches. On the 2018 Infiniti Q60, this size is used as the rear tire on the staggered Red Sport (RWD) configuration, giving it a specific role rather than broad applicability across the model range. The available product in this size is a Nitto NT555 G2 blackwall radial, which keeps the fitment aligned with the Q60's modern performance-oriented tire format. This size matters most when maintaining the proper rear setup on a Red Sport rear-wheel-drive car.
Sub-model fitment matters on the 2018 Infiniti Q60 because wheel diameter and tire size are not the same across the lineup. Most covered trims share a 19-inch tire size, while Red Sport versions use 20-inch fitments and, in rear-wheel-drive form, a staggered front-and-rear arrangement that must be matched correctly.

2018 Infiniti Q60 Luxe
The 2018 Infiniti Q60 Luxe uses the 255/40R19 radial fitment. Tire selection centers on choosing the right 19-inch radial within that size, with sidewall appearance and tire series becoming the main points of comparison.
The 2018 Infiniti Q60 Pure also uses 255/40R19 radials on a 19-inch wheel setup. That keeps fitment straightforward, so the decision moves toward brand, sidewall style, and whether the car still has its original wheel diameter.
The 2018 Infiniti Q60 Red Sport (AWD) uses the 255/35R20 radial size. Because this trim moves to a 20-inch fitment, wheel confirmation is essential before comparing available blackwall, raised white letter, or redline choices.
The 2018 Infiniti Q60 Red Sport (RWD) Front uses 255/35R20 as part of a staggered radial setup. Front tire selection should be matched carefully with the rear size so the car keeps the intended 20-inch front-and-rear relationship.
The 2018 Infiniti Q60 Red Sport (RWD) Rear uses 275/30R20, making it the wider rear portion of the staggered setup. Rear replacement should focus on maintaining the correct 20-inch rear fitment rather than treating it as interchangeable with the front size.
The 2018 Infiniti Q60 Sport (AWD) uses the same 255/40R19 radial size found on several other Q60 trims. That consistency makes size selection simple, leaving appearance, tire series, and wheel compatibility as the main buying considerations.
The 2018 Infiniti Q60 Sport (RWD) uses 255/40R19 radials. As with the other 19-inch Q60 trims, the main choice is among the available tire lines and sidewall presentations while keeping the correct wheel diameter in place.
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 2018 Infiniti Q60 Tires for Sale
Available 2018 Infiniti Q60 tires span 19-inch and 20-inch radial fitments from BFGoodrich, Nitto, and Pro-Trac. The product grid is where to compare blackwall, raised white letter, and redline sidewalls along with tire series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Street Pro III, and NT555 G2.
Q60 tire questions usually come down to exact size by sub-model, 19-inch versus 20-inch wheel fitment, staggered Red Sport setups, and choosing among the available radial tire lines and sidewall styles.
Tire Size & Fitment
What tire size fits a 2018 Infiniti Q60?
The 2018 Infiniti Q60 uses three primary tire sizes: 255/40R19, 255/35R20, and 275/30R20. Luxe, Pure, Sport (AWD), and Sport (RWD) use 255/40R19, Red Sport (AWD) uses 255/35R20, and Red Sport (RWD) uses a staggered setup with 255/35R20 in front and 275/30R20 in the rear.
The practical first step is identifying the exact sub-model and confirming whether the car still has its original 19-inch or 20-inch wheel diameter. A Red Sport rear-wheel-drive car needs both front and rear sizes matched correctly, while the 19-inch trims focus on selecting the right tire within a single size.
What size rim does a 2018 Infiniti Q60 use?
A 2018 Infiniti Q60 uses either a 19-inch or 20-inch rim, depending on the sub-model and tire size. The 255/40R19 fitment uses a 19-inch rim, while both 255/35R20 and 275/30R20 use 20-inch rims.
Rim diameter should be confirmed before comparing tires because the Q60 does not use one wheel size across every trim. It is also worth checking the actual wheel on the car, since aftermarket changes can create a mismatch between the intended sub-model fitment and the wheel diameter currently installed.
Why does the 2018 Infiniti Q60 have more than one tire size?
The 2018 Infiniti Q60 has more than one tire size because different sub-models use different wheel diameters and, in one case, a staggered front-and-rear setup. Most trims use 255/40R19, but Red Sport versions move to 20-inch tires, and Red Sport (RWD) uses a wider rear tire than front.
That means the correct tire cannot be chosen by model name alone. A buyer should verify the trim, whether the car is all-wheel drive or rear-wheel drive, and whether the rear-wheel-drive Red Sport still has its staggered arrangement before selecting replacement tires.
Choosing the Right Tire
What should I consider when choosing a 255/40R19 tire for a 2018 Infiniti Q60?
Start with the correct size, wheel diameter, and radial construction, then compare the character of the available 255/40R19 tires. In this size, choices include BFGoodrich and Pro-Trac products, with tire series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Street Pro III.
Once the basic fitment is confirmed, the main differences become sidewall style, tire series, and wheel-width compatibility where stated. Blackwall keeps a more current appearance, while raised white letter or redline sidewalls create a more distinctive look, so the right choice depends on how the Q60 is driven and presented.
What sidewall styles are available for 2018 Infiniti Q60 tires?
Sidewall choices for the 2018 Infiniti Q60 include blackwall, RWL, and redline, depending on the tire size and product line. Blackwall appears across all three primary sizes, while RWL and redline treatments are available in selected 255/40R19 and 255/35R20 options.
Sidewall style does not change the need to match the correct tire size to the correct sub-model. It mainly affects the visual presentation of the car, so a buyer choosing between blackwall and more expressive sidewall treatments should still confirm wheel diameter, front-versus-rear position on staggered cars, and the intended overall look.
What brands offer tires for the 2018 Infiniti Q60?
Tires for the 2018 Infiniti Q60 are available from BFGoodrich, Nitto, and Pro-Trac. Brand availability depends on size, with BFGoodrich and Pro-Trac appearing in 255/40R19 and 255/35R20, while the 275/30R20 rear Red Sport (RWD) fitment is represented by a Nitto NT555 G2 option.
Brand choice should be compared alongside the exact tire series, sidewall style, and wheel compatibility details for the size you need. On this Q60, the product mix varies enough by fitment that the correct approach is to confirm the sub-model first and then compare only the products built for that specific size.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Infiniti Q60?
A period-style approach on a 2018 Infiniti Q60 still begins with the correct modern radial size for the exact sub-model. Since this is a contemporary luxury sport coupe rather than a vintage bias-ply application, the appearance decision usually comes down to keeping a clean blackwall presentation or choosing a more distinctive sidewall treatment where available.
For a factory-inspired look, many owners stay close to the original wheel diameter and overall visual balance of the car. Raised white letter or redline tires can shift the styling noticeably, so the best choice depends on whether the goal is understated late-model sport coupe appearance or a more customized presentation.
How does tire construction affect the appearance of a restored 2018 Infiniti Q60?
On the 2018 Infiniti Q60, primary fitment is radial across all supported sizes, so construction choice is less about bias-ply versus radial appearance and more about the visual details of the radial tire itself. The biggest appearance changes come from sidewall style, tire series, and whether the car keeps its correct 19-inch or 20-inch wheel setup.
A Q60 that stays close to stock usually looks most cohesive when the wheel diameter and size match the proper trim-level fitment. More customized choices such as RWL or redline sidewalls can create a deliberate style statement, but they should still be selected within the correct front and rear sizing for the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Infiniti Q60?
Yes, modifications can affect tire fitment on a 2018 Infiniti Q60. Wheel changes, altered offsets, suspension lowering, and body modifications can all change how a 255/40R19, 255/35R20, or 275/30R20 tire sits in the wheel opening, even when the tire itself matches one of the Q60's primary sizes.
A modified Q60 should be checked for steering clearance, fender clearance, and front-to-rear size matching if it uses a staggered Red Sport setup. Even a correct nominal size may behave differently on a non-original wheel, so verifying the actual wheel dimensions on the car is just as important as selecting the tire size.
What should I inspect before driving a 2018 Infiniti Q60 on new tires?
Before driving a 2018 Infiniti Q60 on new tires, inspect wheel condition, confirm the correct size at each corner, and make sure the tires are mounted on the intended rim diameter. It is also wise to check inflation pressure, valve stems, lug torque, and whether a staggered Red Sport (RWD) setup has been kept in the proper front-and-rear positions.
A short visual clearance check can prevent rubbing issues, especially if the car has aftermarket wheels or suspension changes. After the first miles, recheck pressure and watch for vibration, uneven seating, or air loss so the new tires can be evaluated before the Q60 returns to regular highway use.
How often should tires on a 2018 Infiniti Q60 be inspected?
Tires on a 2018 Infiniti Q60 should be inspected regularly, especially if the car sees spirited driving or long periods of storage. Check tread condition, sidewall damage, punctures, uneven wear, and air pressure often enough that small issues are caught before they become ride, handling, or safety problems.
Low-use cars deserve extra attention because age and underuse can be just as important as mileage. Looking over the tires before longer drives, after seasonal storage, and whenever ride quality changes helps confirm that the Q60's 19-inch or 20-inch fitment remains in good condition and ready for road use.
