Infiniti G37 Tires

Infiniti G37 fitments in this year range include 225/50R18, 225/45R19, and 245/40R19 for 2008 through 2013, plus 245/45R18 and 225/55R17 for 2009 through 2013. Those sizes correspond to 18-inch, 19-inch, 19-inch, 18-inch, and 17-inch wheels respectively. Several years list multiple sizes at the same time, so the model family does not use one universal tire size.

The practical way to narrow it down is to check the tire placard, the size molded on the current tires, and the actual wheel diameter on the car. On Infiniti G37 applications with staggered fitments, the front and rear sizes may differ, so measure by axle rather than assuming all four tires match.

A 2009 Infiniti G37 can show 225/45R19, 225/50R18, 245/40R19, 245/45R18, and 225/55R17 because the model line used more than one wheel diameter and more than one front-to-rear tire combination. That means the size split is tied to configuration rather than a single across-the-board fitment. The 17-, 18-, and 19-inch wheels each require their own matching tire sizes.

Start by identifying whether the car has 17-, 18-, or 19-inch wheels, then determine whether it uses the same size at all four corners or a staggered setup with wider rear tires. That approach will eliminate most fitment mistakes far faster than searching by year alone.

Infiniti G37 fitments in this range use 17-inch, 18-inch, and 19-inch wheel diameters. The 225/55R17 size uses a 17-inch rim, 225/50R18 and 245/45R18 use 18-inch rims, and 225/45R19 plus 245/40R19 use 19-inch rims. Seventeen-inch fitments appear from 2009 onward, while 18- and 19-inch sizes run across the full 2008 to 2013 span.

Wheel diameter is the first thing to verify because a tire cannot be mounted on the wrong rim diameter even if the width and overall look seem close. Check the marking cast or stamped on the wheel and compare it with the tire size already on the car before moving on to brand or tread selection.

On an Infiniti G37, 225/45R19 means the tire is 225 millimeters wide, has a sidewall height equal to 45 percent of that width, uses radial construction, and fits a 19-inch wheel. It is one of the metric radial sizes used on the model across 2008 through 2013. The code is describing both the tire’s dimensions and the wheel diameter it must fit.

That size should only be chosen when the car actually carries 19-inch wheels and the specific axle calls for the narrower 225-width fitment. If the Infiniti G37 has a staggered setup, the matching rear tire may be a different 19-inch size, so verify both front and rear before replacing a pair.

A 2011 Infiniti G37 can use 225/45R19, 225/50R18, 245/40R19, 245/45R18, or 225/55R17, depending on wheel package and axle position. That means the year alone is not enough to select the tire. The correct size is the one that matches the wheel diameter and the front or rear position on the actual car.

Check the size molded into the current tires, compare front and rear, and confirm the wheel diameter before making a selection. If the car has been modified with aftermarket wheels, rely on the installed wheel and tire measurements rather than assuming the original factory-style combination is still in place.

Infiniti G37 tire offerings here include Blackwall, Wide Whitewall, and Redline sidewall styles. Blackwall choices appear across all five fitment sizes, while the Wide Whitewall and Redline options are available in 225/55R17 through the BFGoodrich Silvertown Radial line. That gives the model a split between contemporary performance-oriented appearance and a more custom or period-inspired look.

Most Infiniti G37 owners seeking an original modern sport-luxury presentation will stay with blackwalls. Wide whitewall and redline tires can be useful when the goal is a custom build, tribute styling direction, or a very specific visual statement, but they should still be matched to the correct 17-inch wheel fitment.

The brands listed for Infiniti G37 fitments here are BFGoodrich and Nitto. BFGoodrich covers all five listed sizes with several g-Force and Silvertown Radial choices, while Nitto appears in 245/45R18 with the NT555 G2. That means brand selection is broadest in some sizes and narrower in others.

If appearance and tire series matter as much as size, begin by confirming which fitment your car uses and then compare the options within that exact size. A 17-inch Infiniti G37 opens the door to more sidewall-style variety, while some 18- and 19-inch sizes are focused more tightly on modern blackwall performance radials.

Infiniti G37 offerings here include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Silvertown Radial, and Nitto NT555 G2. Those series reflect different approaches, from all-season-oriented performance and summer-style sport radials to appearance-driven specialty radials with wide whitewall or redline sidewalls. All listed choices are radial-construction tires, but they are not all aimed at the same look or driving character.

Choose first by correct size and wheel diameter, then by the role the car plays. A regularly driven Infiniti G37 may call for a modern blackwall performance radial, while a custom or show-oriented build on 17-inch wheels may lean toward the Silvertown Radial for its visual presentation.

An Infiniti G37 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and extreme temperature swings. Keeping the tires properly inflated helps prevent flat spotting and sidewall stress during long periods of inactivity. If the car will sit for an extended season, moving it occasionally or supporting it to reduce constant load can help preserve the tires’ shape.

Collector-car storage habits matter even on modern radial tires because low annual mileage often means age becomes a bigger factor than tread wear. Before the car goes back into regular use, inspect all four tires for pressure loss, cracking, irregular wear, and any sign that the fronts and rears have aged differently.

Tires on an Infiniti G37 should be visually checked every time the car is driven after storage and inspected more thoroughly at regular service intervals. Look for cracking, punctures, uneven shoulder wear, center wear from overinflation, and signs that one axle is wearing faster than the other. On a staggered setup, compare each axle separately rather than assuming all four tires should wear the same way.

Frequent inspection is especially important on enthusiast cars because they may sit for long periods and then return to spirited use. A quick walk-around before each drive and a deeper inspection several times a year will catch age, pressure, or alignment problems before they become expensive or unsafe.

An Infiniti G37 tire should be replaced when age, cracking, impact damage, sidewall bulges, repeated air loss, or internal deterioration becomes evident, even if tread depth still looks usable. Performance-oriented radials can appear serviceable while rubber hardening has already reduced grip and braking effectiveness. Uneven wear patterns can also point to replacement time if the tire can no longer wear evenly or safely.

On a low-mileage collector or weekend-driven Infiniti G37, age often ends tire service life before the tread is consumed. If the car has sat unused for extended periods or the tires have an uncertain service history, a hands-on inspection by a tire professional is the best way to decide whether continued road use is wise.

Infiniti G37 used more than one tire size during its 2008 through 2013 run, including 225/50R18, 225/45R19, 245/40R19, 245/45R18, and 225/55R17 depending on year and configuration. The available tire series here are all modern radial products rather than a single original-equipment pattern. That makes the correct original-style reference point the specific year, wheel package, and axle arrangement on the car being restored.

For an authenticity-focused project, verify the car’s original wheel diameter and whether it left the factory with a square or staggered setup before choosing a replacement tire. If the goal is faithful modern-era appearance, blackwall radials in the proper metric size will generally align more closely with how an Infiniti G37 was presented when new.

Correct tire fitment does affect how an Infiniti G37 is viewed, especially when the car is being preserved as an unmodified example or judged in marque-oriented circles. The right size, wheel diameter, sidewall treatment, and front-to-rear pairing all contribute to whether the car presents as factory-correct or intentionally customized. Even on a newer collector car, visibly incorrect proportions can hurt credibility.

If value retention or event judging matters, match the tire size to the car’s actual wheel package and intended presentation. A tasteful custom choice such as redlines or wide whitewalls may suit a modified Infiniti G37, but an original-spec restoration is better served by staying close to the appropriate blackwall radial fitment.

For a restoration-minded Infiniti G37, Blackwall is the sidewall style that most closely fits the model’s modern sport-luxury character. Wide Whitewall and Redline options are also available in 225/55R17, but those choices create a distinctly custom visual effect rather than a typical production-era look for the G37. Sidewall style therefore changes the presentation of the car almost as much as wheel design does.

Choose blackwalls when the goal is a factory-style restoration or an OEM-like appearance. Consider redline or wide whitewall only when the car is being built in a custom direction and the 17-inch fitment is already correct, since appearance should never come ahead of matching the wheel diameter and tire size properly.

These Infiniti G37 tires are modern radial designs intended for road use when they are the correct size for the wheel, are properly mounted, and are in sound condition. The listed fitments include contemporary performance-oriented series as well as specialty-style radials, but safety still depends on matching the right size to the right axle and maintaining the tire correctly. A wrong-size tire can create handling, clearance, and load issues even if it physically mounts.

Before regular road use, verify wheel diameter, front and rear sizing, inflation condition, and overall tire age. If the car has been modified or lowered, pay extra attention to fender, suspension, and inner-wheel-well clearance because the safest tire is the one that fits the actual car without rubbing or overstressing the chassis.

Before driving an Infiniti G37, check inflation pressure, inspect the sidewalls and tread for visible damage, and confirm that the front and rear tires match the intended setup for the car. Also look for uneven wear that may suggest alignment or suspension issues, especially on a performance coupe or sedan that has seen spirited use. Any vibration, pull, or recurring pressure loss deserves attention before the car returns to normal road speeds.

A short pre-drive inspection is especially valuable after storage or after wheel changes. Infiniti G37 fitments can vary by diameter and axle, so confirming that all four tires are the correct size and are mounted where they belong is one of the simplest ways to avoid preventable handling problems.

An Infiniti G37 should only be driven at speeds appropriate to the condition, age, and exact service rating of the tires fitted to it, not merely the car’s performance potential. Several listed sizes use modern ZR-designated performance fitments, but real-world safe speed still depends on inflation, temperature, road surface, load, and whether the tires are fresh and evenly worn. The vehicle itself can exceed what an aged or compromised tire should be asked to do.

Treat tire condition as the governing limit, especially on a collector or infrequently driven Infiniti G37. If the car has older tires or uncertain history, use conservative speeds until the tires have been fully inspected and evaluated, because a modern performance chassis can quickly expose weaknesses in worn or hardened rubber.
