The 2015 Infiniti Q60 sits at the close of Infiniti’s G-based coupe and convertible lineage, blending grand-touring comfort with a more athletic rear-wheel-drive character than many luxury sport coupes of its era. That mix makes tire fitment especially important, because this car uses staggered front and rear sizing in some configurations and offers both 18-inch and 19-inch wheel packages across the range. All primary fitments are radial, with 225-width front sizes and 245-width rear sizes depending on wheel diameter and sub-model layout. The real decision is confirming your exact front or rear application first, then choosing the right series, load specification, and road-use character for the way the car is equipped.
Which Tire Size Is Right for The 2015 Infiniti Q60
The 2015 Infiniti Q60 uses four primary tire sizes, and the right one depends first on whether you are matching a front or rear position and whether the car is equipped with 18-inch or 19-inch wheels. All of these fitments are radial, so the key choice is confirming the exact wheel diameter and axle position before comparing available tire series, load specifications, and product details.
Fit(s): Base Front, IPL Front, Journey, Journey Front, S Convertible Front, S Coupe Front, and S Limited Front
Construction: Radial|Rim: 19 in
225/45R19 is a metric radial size with a 225-millimeter section width, a 45-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2015 Infiniti Q60, this is a front-position size used on several 19-inch-wheel configurations, including IPL, S, and some Journey applications. Available choices center on BFGoodrich blackwall performance-oriented series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This size matters when preserving the intended front fitment on a 19-inch setup rather than mixing front and rear dimensions or crossing over to the 18-inch package.
225/50R18 is a metric radial size that uses a 225-millimeter section width, a 50-series profile, and an 18-inch wheel diameter. On the 2015 Infiniti Q60, it serves as a front tire size for certain Base and Journey configurations equipped with 18-inch wheels. Product choices include BFGoodrich blackwall options across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. This is the size to evaluate when the car has the 18-inch front wheel package and you want to keep the fitment matched to that wheel diameter and front-axle role.
Fit(s): Base Rear, IPL Rear, Journey Rear, S Convertible Rear, S Coupe Rear, and S Limited Rear
Construction: Radial|Rim: 19 in
245/40R19 is a metric radial size with a 245-millimeter section width, a 40-series profile, radial construction, and a 19-inch rim diameter. On the 2015 Infiniti Q60, this is the rear-position size used with 19-inch staggered setups on IPL, S, and certain Journey configurations. BFGoodrich offers this size in blackwall form through the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. It should be chosen only when matching the rear axle of a 19-inch configuration, since its width and profile are part of the car’s staggered front-to-rear fitment strategy.
245/45R18 is a metric radial size combining a 245-millimeter section width with a 45-series profile on an 18-inch wheel. On the 2015 Infiniti Q60, it fills the rear position for 18-inch staggered applications, pairing with the narrower 225/50R18 front size. Available blackwall choices include several BFGoodrich g-Force lines as well as the Nitto NT555 G2, giving this rear size the broadest product mix on the page. This is the size to confirm when the car carries an 18-inch rear wheel and you want to keep the staggered balance appropriate to that axle position.
Sub-model fitment on the 2015 Infiniti Q60 is closely tied to wheel diameter and front-versus-rear position. Some versions use 18-inch front and rear pairings, while others use a 19-inch staggered setup, so identifying the exact sub-model and axle position is essential before choosing a tire.

2015 Infiniti Q60 Base Front
The 2015 Infiniti Q60 Base Front uses one of two front radial sizes depending on whether the car is equipped with 18-inch or 19-inch wheels. Tire selection starts with confirming the wheel diameter on the car, then comparing blackwall performance-oriented options within the matching front size.
The 2015 Infiniti Q60 Base Rear uses one of two rear radial sizes, matched to either an 18-inch or 19-inch staggered wheel package. Rear-tire selection should stay tied to the actual rear wheel diameter so the wider rear fitment remains consistent with the car’s axle-specific setup.
The 2015 Infiniti Q60 IPL Front uses a 19-inch front radial fitment. That makes the buying decision more straightforward, with the focus shifting from size identification to choosing the right tire series and specification within the correct front application.
The 2015 Infiniti Q60 IPL Rear uses a 19-inch rear radial fitment paired with the wider rear section width typical of the staggered setup. Tire choice here should keep the correct rear size in place and avoid substituting a front-size tire simply because the overall diameter appears similar.
The 2015 Infiniti Q60 Journey appears with both 18-inch and 19-inch tire configurations, so size selection depends on the wheel package actually on the car. Matching front and rear sizes to that package is more important than choosing a tire series first.
The 2015 Infiniti Q60 Journey Front uses the 19-inch front radial size in this configuration. Once that front fitment is confirmed, the decision becomes which blackwall performance-oriented tire line best suits the car’s intended road use.
The 2015 Infiniti Q60 Journey Rear uses the 19-inch rear radial size in this configuration. Rear replacement should stay axle-specific, with attention paid to keeping the wider rear tire matched to the wheel diameter already on the car.
The 2015 Infiniti Q60 S Convertible Front uses a 19-inch front radial fitment. That keeps size confirmation simple, leaving the main decision centered on tire series, rim-width compatibility, and the kind of driving the convertible actually sees.
The 2015 Infiniti Q60 S Convertible Rear uses a 19-inch rear radial size. Choosing for this position means keeping the rear tire matched to the staggered layout rather than treating the car as though it uses the same size at all four corners.
The 2015 Infiniti Q60 S Coupe Front uses the 19-inch front radial size. With size settled, the useful comparison points are tire series, blackwall presentation, and whether the tire’s specifications suit the car’s wheel width and driving style.
The 2015 Infiniti Q60 S Coupe Rear uses the wider 19-inch rear radial fitment. Tire selection should keep that rear-specific sizing intact so the car’s staggered setup is not compromised by an incorrect width or rim-diameter change.
The 2015 Infiniti Q60 S Limited Front uses the 19-inch front radial size. Once the front axle application is confirmed, product choice comes down to comparing the available BFGoodrich series and making sure the tire matches the wheel width on the car.
The 2015 Infiniti Q60 S Limited Rear uses the 19-inch rear radial fitment. Rear replacement should remain tied to that specific axle position, especially on a staggered setup where width and wheel diameter are both part of the intended tire arrangement.
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 2015 Infiniti Q60 Tires for Sale
Available 2015 Infiniti Q60 tires focus on modern radial blackwall performance fitments in all four primary sizes. Most choices come from BFGoodrich across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, while 245/45R18 also includes a Nitto NT555 G2 option.
Q60 tire questions usually come down to front-versus-rear sizing, 18-inch versus 19-inch wheels, and how to compare the available radial tire series. The FAQs below focus on exact fitment, product selection, and the checks worth making before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 2015 Infiniti Q60?
The 2015 Infiniti Q60 uses four primary tire sizes: 225/45R19, 225/50R18, 245/40R19, and 245/45R18. The narrower 225-section sizes are used at the front, while the wider 245-section sizes are used at the rear, with the exact pairing determined by whether the car has an 18-inch or 19-inch wheel package.
That means the first step is not choosing a brand but confirming wheel diameter and axle position. A Q60 with 19-inch wheels uses a different front-and-rear pairing than one with 18-inch wheels, and staggered setups should be matched carefully so front and rear tire sizes stay appropriate to the car’s actual configuration.
What size rim does a 2015 Infiniti Q60 use?
The 2015 Infiniti Q60 uses either 18-inch or 19-inch rims, depending on the version and tire position. The primary tire sizes are built around those diameters, with 225/50R18 and 245/45R18 for 18-inch setups, and 225/45R19 and 245/40R19 for 19-inch setups.
Rim diameter should be verified before anything else because an 18-inch tire cannot be mounted on a 19-inch wheel, and the reverse is just as true. It also helps to confirm wheel width, especially on staggered cars, since the available products are matched to specific rim-width ranges within each size.
Why does the 2015 Infiniti Q60 have more than one tire size?
The 2015 Infiniti Q60 has more than one tire size because fitment varies by wheel package and by front-versus-rear position. Some configurations use an 18-inch staggered setup with 225/50R18 front and 245/45R18 rear, while others use a 19-inch staggered setup with 225/45R19 front and 245/40R19 rear.
That variation is normal for a sport-oriented coupe or convertible with multiple trim and wheel combinations. The practical takeaway is to check the exact sub-model, then verify the wheel size on the car itself, especially if it has changed hands before or has been fitted with aftermarket wheels at any point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Infiniti Q60?
Start with the exact size required for the front or rear of the 2015 Infiniti Q60 and make sure it matches the wheel diameter on the car. From there, compare the tire series available in that size, the rim-width range, and any load figures given for the product you are considering.
A Q60 with a staggered setup needs the correct axle-specific sizing preserved, so the decision is more than simply picking a tire that mounts on the wheel. It helps to think about how the car is used as well, whether that means regular street driving, seasonal use, or a more performance-oriented role.
What sidewall styles are available for 2015 Infiniti Q60 tires?
The available 2015 Infiniti Q60 tire choices shown here use a blackwall sidewall style across all four primary sizes. That gives the page a very consistent modern performance look rather than offering multiple sidewall treatments such as whitewall, raised white letter, or stripe variations.
Since sidewall appearance is not the differentiator on this Q60 fitment, the more useful comparison points are tire series, wheel-diameter match, rim-width compatibility, and any load specification attached to the product. Buyers trying to maintain a clean contemporary appearance will find that blackwall presentation is consistent throughout these options.
What brands offer tires for the 2015 Infiniti Q60?
BFGoodrich appears across all four primary 2015 Infiniti Q60 tire sizes, with choices in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. Nitto also appears in 245/45R18, where the NT555 G2 adds another rear-tire option for the 18-inch setup.
That brand spread means some sizes are more varied than others, especially the 18-inch rear fitment. A useful approach is to narrow the search by exact size first, then compare the available series within that size rather than assuming every brand or tire line is offered across the whole Q60 range.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Infiniti Q60?
Yes, modifications can affect tire fitment on a 2015 Infiniti Q60, especially because the car uses staggered front and rear sizing and may be equipped with either 18-inch or 19-inch wheels. Aftermarket wheels, suspension changes, lowering, or spacer use can all change the clearance relationship around the tire.
That makes it important to inspect the actual setup on the car rather than relying only on what the trim originally used. Wheel diameter, wheel width, and available clearance at the fender, strut, and steering components should all be checked before selecting a replacement tire for a modified Q60.
What should I inspect before driving a 2015 Infiniti Q60 on new tires?
Before driving a 2015 Infiniti Q60 on new tires, inspect the wheel size, confirm that the correct front and rear sizes were installed, and check air pressure after mounting. It is also smart to look over the wheels for damage and make sure there is no interference at the suspension, brake, or inner fender areas.
A short initial road test can reveal vibration, pull, or clearance issues that are easier to address early. Rechecking inflation, looking for any signs of rubbing, and confirming that the staggered setup was maintained correctly are especially worthwhile on a Q60 that uses different sizes front and rear.
How often should tires on a 2015 Infiniti Q60 be inspected?
Tires on a 2015 Infiniti Q60 should be inspected regularly, not just when tread looks low. Pressure loss, uneven wear, sidewall cuts, bulges, and age-related deterioration can all develop long before a tire appears obviously worn, especially on cars that spend part of the year parked or driven only occasionally.
A frequent visual check is a good habit, and a closer inspection before longer drives is even better. Because the Q60 may run different sizes at the front and rear, uneven wear can be less obvious at a glance, so each axle should be checked on its own rather than assuming all four tires are aging the same way.
