2013 Infiniti G37 Tires

The 2013 Infiniti G37 uses five primary tire sizes: 225/45R19, 225/50R18, 245/40R19, 245/45R18, and 225/55R17. Every one of those fitments is a radial, but they do not all apply to the same version of the car. Some G37 models use a square setup, while others use different front and rear sizes.

Finding the right size starts with the exact sub-model and wheel package, not the G37 name alone. A sedan, coupe, convertible, IPL, Sport, Journey, or X configuration can change the answer, and staggered applications require confirming both front and rear sizes before comparing actual tire choices.

A 2013 Infiniti G37 can use 17-inch, 18-inch, or 19-inch rims depending on configuration. The 225/55R17 fitment uses a 17-inch rim, the 225/50R18 and 245/45R18 fitments use 18-inch rims, and the 225/45R19 and 245/40R19 fitments use 19-inch rims.

Wheel diameter should be verified before anything else because it narrows the fitment immediately. It also helps determine whether the car is using a square arrangement or a staggered front-and-rear setup, which affects how the tire sizes should be matched across the vehicle.

The 2013 Infiniti G37 covers several body styles and trim-specific wheel packages, so it does not rely on one universal tire size. Some versions use a single size at all four corners, while others use narrower front tires and wider rear tires, particularly in 18-inch and 19-inch staggered applications.

That means the correct choice depends on the exact configuration and the wheels currently on the car. A G37 that has been changed from its original wheel package can require a different answer than a stock example, so it is worth checking both the sub-model and the actual front and rear wheel setup.

Start with the correct size for the exact 2013 Infiniti G37 configuration, then confirm whether the car uses a square setup or staggered front and rear tires. From there, compare construction, tire series, rim-width compatibility, and any load figures given for the specific size you need.

The product range includes performance-oriented blackwall choices and, in 225/55R17, more appearance-driven options such as wide whitewall and redline. That makes intended use important: a daily-driven sedan, a sport-oriented coupe, and a custom-styled G37 may all point toward different tire series even when the basic size is correct.

Most 2013 Infiniti G37 tire options are blackwall radials, especially in the 18-inch and 19-inch sizes. The 225/55R17 fitment adds more visual variety, with BFGoodrich Silvertown Radial choices available in wide whitewall and redline alongside blackwall performance tires.

Sidewall style does not change the need to match the correct size and wheel diameter, but it can change the car’s presentation significantly. A blackwall keeps a modern sport-sedan look, while redline or wide whitewall can push a 17-inch G37 toward a more customized or retro-inspired appearance.

BFGoodrich covers every primary tire size used on the 2013 Infiniti G37, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and selected Silvertown Radial applications. Nitto also appears in the 245/45R18 rear size with the NT555 G2.

Brand choice matters most after the correct fitment has been confirmed. Once size and wheel setup are settled, the buyer can compare series character, sidewall appearance, rim-width specifications, and load details where shown, rather than assuming any tire from the right brand will suit every G37 configuration equally well.

Yes, modifications can change what works on a 2013 Infiniti G37 even when the original size is known. Aftermarket wheels, altered wheel widths, suspension changes, lowering, or body modifications can all affect clearance and the way a 17-inch, 18-inch, or 19-inch tire sits on the car.

That is especially important on staggered G37 setups, where front and rear sizing already differ. Checking the actual wheel diameter, wheel width, and available clearance at both axles helps prevent choosing a tire that matches the catalog fitment on paper but conflicts with the car’s current setup.

Before road use, inspect the wheel condition, valve stems, and tire pressure, and make sure the new tires match the correct axle position on any staggered 2013 Infiniti G37 setup. It is also smart to look over suspension and alignment-related wear items if the old tires showed uneven wear patterns.

A short clearance check at full steering lock can help on cars with larger wheels or prior modifications. After the first drives, recheck pressure and watch for vibration, rubbing, or unusual wear, since those symptoms often point to balance, alignment, or wheel-fitment issues rather than the tire size alone.

Tires on a 2013 Infiniti G37 should be inspected regularly for pressure loss, irregular tread wear, cuts, bulges, and sidewall damage. Cars that are driven infrequently still need attention, because aging, flat spotting, and air loss can develop even when tread depth still looks usable.

A routine visual check before longer drives is especially worthwhile on performance-oriented staggered setups, where front and rear tires are not interchangeable. Keeping an eye on wear patterns also helps catch alignment or suspension issues early, which protects both the tire investment and the way the G37 drives.
