The 2014 Infiniti Q60 sits at the point where Infiniti’s G-based coupe and convertible formula had matured into a refined grand-touring package with a more performance-focused identity. Buyers looking at this exact car are usually balancing style, road manners, and the importance of keeping the front and rear tire setup properly matched. This Q60 uses radial tire fitments in four sizes across 18-inch and 19-inch wheel packages: 225/50R18, 245/45R18, 225/45R19, and 245/40R19. Available choices center on blackwall performance-oriented tires from BFGoodrich and Nitto across several series. The key is confirming your exact wheel setup and whether your car uses a square or staggered arrangement before selecting replacements.
Which Tire Size Is Right for The 2014 Infiniti Q60
The 2014 Infiniti Q60 uses four primary tire sizes, and the right one depends first on whether the car has 18-inch or 19-inch wheels and whether you are replacing a front or rear tire on a staggered setup. All four sizes are radial fitments, so the decision is less about vintage construction and more about confirming wheel diameter, axle position, and the exact sub-model configuration before choosing among the available performance tire options.
Fit(s): Convertible Front, Coupe, Coupe Front, IPL Convertible Front, IPL Coupe Front, Journey, Journey Front, Sport Convertible Front, and Sport Coupe Front
Construction: Radial|Rim: 19 in
225/45R19 is a metric radial size in which 225 identifies the tire's nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2014 Infiniti Q60, this size is used as a front fitment on 19-inch applications. Available choices are blackwall performance tires from BFGoodrich in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This is the size to evaluate when the car carries 19-inch front wheels and the goal is preserving the intended front-end fitment and stance.
Fit(s): Convertible Front, Coupe, Journey, and Sport Convertible Front
Construction: Radial|Rim: 18 in
225/50R18 follows the same modern metric radial format, with a 225-millimeter section width, a 50-series profile, radial construction, and an 18-inch rim diameter. On the 2014 Infiniti Q60, this size serves as a front tire on 18-inch wheel setups. BFGoodrich offers it in blackwall form through the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, giving buyers several ways to stay within the proper size. Choose this fitment when your Q60 is equipped with 18-inch front wheels and you want to keep the correct front tire dimensions.
Fit(s): Convertible Rear, Coupe Rear, IPL Convertible Rear, IPL Coupe Rear, Journey Rear, Sport Convertible Rear, and Sport Coupe Rear
Construction: Radial|Rim: 19 in
245/40R19 is a wider metric radial size, with 245 showing nominal section width in millimeters, 40 indicating a lower-profile sidewall, R for radial construction, and 19 for wheel diameter. On the 2014 Infiniti Q60, this size is used at the rear on 19-inch staggered applications. BFGoodrich offers blackwall choices in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This is the rear size to confirm when replacing tires on a 19-inch setup, especially if the car uses a narrower front tire and wider rear tire combination.
Fit(s): Convertible Rear and Sport Convertible Rear
Construction: Radial|Rim: 18 in
245/45R18 uses the modern metric radial format and denotes a 245-millimeter nominal section width, a 45-series profile, radial construction, and an 18-inch wheel diameter. On the 2014 Infiniti Q60, it serves as the rear fitment on 18-inch applications. Available blackwall options include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2. This size matters when your Q60 runs an 18-inch staggered setup and you want to keep the correct rear width, wheel match, and overall fitment balance.
Sub-model fitment on the 2014 Infiniti Q60 varies by body style, trim, axle position, and wheel package, so tire selection is not one-size-fits-all. It is important to confirm both the exact sub-model and whether you are replacing a front or rear tire, especially on staggered 19-inch applications.

Owners of a 2014 Infiniti Q60 usually need clear answers on front and rear tire sizing, 18-inch versus 19-inch wheel fitment, available radial tire choices, and what to inspect before putting a performance coupe or convertible back on the road.
Tire Size & Fitment
What tire size fits a 2014 Infiniti Q60?
The 2014 Infiniti Q60 uses four primary radial tire sizes: 225/45R19, 225/50R18, 245/40R19, and 245/45R18. The narrower 225 sizes are front fitments, while the wider 245 sizes are rear fitments. Wheel diameter determines which pair applies, with either an 18-inch or 19-inch setup.
The practical first step is checking the actual wheel diameter on the car and confirming whether you are replacing a front or rear tire. Many Q60 configurations use a staggered arrangement, so matching the correct axle position matters just as much as matching the wheel size.
What size rim does a 2014 Infiniti Q60 use?
A 2014 Infiniti Q60 uses either 18-inch or 19-inch rims, depending on the exact configuration. The 225/50R18 and 245/45R18 sizes belong to 18-inch wheels, while the 225/45R19 and 245/40R19 sizes belong to 19-inch wheels.
Verifying rim diameter before ordering is important because a tire designed for an 18-inch wheel cannot be mounted on a 19-inch wheel, and vice versa. It also helps to confirm front and rear wheel sizing separately if the car has staggered wheels or has been changed from its original setup.
Why does the 2014 Infiniti Q60 have more than one tire size?
The 2014 Infiniti Q60 has more than one tire size because fitment varies by wheel package and axle position. Some versions use 18-inch front and rear pairings, while others use 19-inch pairings, and the rear tire is wider than the front on staggered applications.
That means tire selection should start with the exact sub-model, wheel diameter, and whether the tire is going on the front or rear axle. A Q60 that has aftermarket wheels or a mixed replacement history should be inspected carefully so the new tire matches the wheel actually installed on that corner.
Choosing the Right Tire
What should I consider when choosing a 2014 Infiniti Q60 tire?
Start with the correct size for the exact wheel and axle position, since the 2014 Infiniti Q60 uses both front and rear-specific fitments across 18-inch and 19-inch packages. All available options here are radial tires, so the main variables become series choice, load specification where stated, and the tire's approved rim-width range.
A good selection process also accounts for how the car is used. A weekend coupe, daily-driven convertible, or modified Q60 may place different priorities on tire choice, but the size still needs to match the wheel and the front-to-rear arrangement already on the car.
What brands offer tires for the 2014 Infiniti Q60?
BFGoodrich covers all four primary 2014 Infiniti Q60 sizes, and Nitto is available in 245/45R18. Within the BFGoodrich range, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, giving the Q60 owner several radial performance-oriented options.
Brand choice should still come after fitment confirmation. Once the correct front or rear size is identified, compare each tire's series, load details when stated, and rim-width specifications rather than assuming every tire in the same nominal size serves the same purpose on the car.
What tire series are available for the 2014 Infiniti Q60?
The 2014 Infiniti Q60 is offered with several radial tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2 in 245/45R18. These series appear across the Q60's front and rear sizes rather than in one universal fitment.
Series matters because it gives the buyer a useful way to compare available options without leaving the correct size. After confirming wheel diameter and axle position, review the tire series alongside sidewall style, load specification, and approved wheel-width range to narrow the right match for the car's setup.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Infiniti Q60?
A period-style 2014 Infiniti Q60 tire choice begins with keeping the proper modern radial size for the car's actual wheel package and axle position. Since the available options here are blackwall performance tires, the visual presentation stays close to the clean, contemporary look that suits a 2014 Infiniti coupe or convertible.
Appearance should still follow fitment, not replace it. Confirm whether the car uses 18-inch or 19-inch wheels and whether it has a staggered front-to-rear setup, then choose the tire series that best supports the look and use of the vehicle without altering the basic size relationship.
Does correct tire fitment matter for a 2014 Infiniti Q60 restoration?
Correct tire fitment matters on a 2014 Infiniti Q60 restoration because the car's stance, wheel-to-tire relationship, and overall presentation depend on using the proper front and rear sizes. A mismatched diameter or incorrect axle placement can change the visual balance of the coupe or convertible noticeably.
For a restoration-minded owner, the best approach is to confirm the wheel package currently on the car and keep the correct radial size tied to that setup. If the goal is greater originality, comparing the car to period photos, window-sticker records, or marque-specific references can help guide the final appearance choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Infiniti Q60?
Yes, modifications can affect tire fitment on a 2014 Infiniti Q60. Aftermarket wheels, suspension changes, lowering, or body alterations can change the clearance available for the Q60's front and rear tire sizes, even when the nominal size still looks close to a standard 18-inch or 19-inch fitment.
A modified car should be checked at each corner for wheel diameter, wheel width, and available clearance through steering and suspension travel. That is especially important on a staggered setup, where front and rear tires already differ in width and profile from the factory-style size arrangement.
What should I inspect before driving a 2014 Infiniti Q60 on new tires?
Before driving a 2014 Infiniti Q60 on new tires, inspect wheel condition, confirm the correct size is mounted at the proper axle position, and verify inflation pressure after installation. It is also wise to look over the suspension, alignment condition, and brake components so the new tires are not starting life on a compromised chassis.
A short initial road test can reveal rubbing, vibration, or handling irregularities that deserve attention right away. Rechecking pressure and visually confirming clearance after a few miles is a smart follow-up, particularly on cars with staggered wheels, previous modifications, or a long period of storage.
How should tires on a collector 2014 Infiniti Q60 be maintained?
Tires on a collector 2014 Infiniti Q60 should be maintained with regular pressure checks, routine visual inspection, and close attention to age-related deterioration. Even low-mileage tires can develop cracking, flat spotting, or air loss when a car spends long periods parked rather than being driven consistently.
Storage conditions matter as much as mileage on a low-use Q60. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and periodic inspections of tread, sidewalls, and valve areas can catch problems before the next drive or seasonal outing.
