2011 Infiniti G37 Tires

The 2011 Infiniti G37 uses several radial tire sizes: 225/45R19, 225/50R18, 245/40R19, 245/45R18, and 225/55R17. The correct size depends on the exact coupe, sedan, convertible, sport, IPL, or X configuration, and some versions use staggered fitment with one size in front and a wider size in back.

The practical first step is identifying the exact sub-model and confirming whether the car carries 17-, 18-, or 19-inch wheels. On staggered applications, replacing front and rear tires by position matters just as much as choosing the correct size code, especially if the car has aftermarket wheels or a changed suspension setup.

A 2011 Infiniti G37 can use 17-inch, 18-inch, or 19-inch rims depending on the specific version and tire size. The covered fitments pair 225/55R17 with 17-inch wheels, 225/50R18 and 245/45R18 with 18-inch wheels, and 225/45R19 and 245/40R19 with 19-inch wheels.

Rim diameter should be confirmed before anything else because the G37 does not rely on one universal wheel size across the range. Checking the wheel itself is especially important when the car has been modified, when trim history is unclear, or when a previous owner may have changed from the original wheel package.

The 2011 Infiniti G37 was offered in multiple body styles and trim configurations, so tire fitment changes with the wheel package and with square versus staggered setups. Some versions use one size at all four corners, while sport-oriented applications use a narrower front tire and a wider rear tire.

That means the correct replacement tire is tied to the exact car rather than the G37 name alone. A coupe, sedan, convertible, IPL model, or X model can point to different sizes, and front and rear fitment may need to be checked separately before selecting a replacement tire.

Start with the exact tire size required for the specific 2011 Infiniti G37 configuration, then confirm whether the car uses a square setup or staggered front-and-rear sizes. After that, compare radial tire series, wheel-width compatibility, and any load information shown for the size you need.

Appearance can matter too, especially in 225/55R17 where blackwall, wide whitewall, and redline choices are available. A car driven regularly may call for a different product focus than one built around style or occasional use, so the best comparison points are size, wheel fit, intended use, and sidewall presentation.

Most 2011 Infiniti G37 tire options are blackwall radials, especially in the 18-inch and 19-inch sizes used on many coupe, sport, and staggered-fitment applications. The 225/55R17 size also opens up BFGoodrich Silvertown Radial choices with wide whitewall and redline sidewall treatments.

That gives 17-inch sedan applications the widest styling range of any G37 fitment covered here. Sidewall style should still be chosen only after the size and rim diameter are confirmed, since appearance options do not override the need to match the vehicle’s actual wheel package and fitment layout.

BFGoodrich is the primary brand across the 2011 Infiniti G37 size range, with g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Silvertown Radial offerings appearing in the covered fitments. Nitto also appears in 245/45R18 with the NT555 G2.

Brand comparison should be done within the correct size and wheel application first, since not every line is available in every G37 fitment. It also helps to compare sidewall style, intended use, and wheel-width range so the tire choice suits the car’s actual setup rather than just the brand name.

A period-style approach on a 2011 Infiniti G37 usually begins with keeping the exact size and wheel diameter already used by the car, then selecting a tire whose appearance supports the build. The clearest styling options appear in 225/55R17, where blackwall, wide whitewall, and redline radial choices are available.

That approach works best for an owner who wants a more distinctive visual presentation without moving away from the correct primary size. Exact originality claims for a modern collector-era Infiniti should be checked against marque-specific references, but size accuracy and proper wheel fit remain the most important starting points.

On the 2011 Infiniti G37, the covered fitments are all radial, so the appearance difference comes less from construction changes and more from sidewall treatment and tire series. Blackwall performance radials create the most contemporary look, while wide whitewall and redline 225/55R17 options shift the car toward a more custom or nostalgic presentation.

That makes the visual decision highly dependent on the specific G37 build and wheel package. A sedan on 17-inch wheels offers more room for appearance-driven sidewall choices, while many 18-inch and 19-inch sport setups remain centered on blackwall performance-oriented tires that match the car’s later-model character.

Yes. Wheel changes, altered offset, suspension lowering, and other modifications can affect tire fitment on a 2011 Infiniti G37 even when the tire size looks close to the original application. That is especially important on staggered 18-inch and 19-inch setups where front and rear sizes already serve different roles.

Clearance should be checked at full steering lock and through suspension travel if the car has aftermarket wheels or chassis changes. A modified G37 may also need extra attention to wheel width and rear clearance, since a tire that matches the size code still has to work with the actual wheel and body setup.

Before driving a 2011 Infiniti G37 on new tires, inspect wheel condition, confirm the tire sizes match the exact front and rear positions, and make sure inflation is set appropriately for the installed tires. It also helps to verify that the wheels are the intended 17-, 18-, or 19-inch diameter for the configuration.

A short check of alignment, visible suspension wear, and fender or strut clearance can prevent problems that are blamed on the tires later. After installation, watch for vibration, uneven wear, or rubbing, since those signs usually point to wheel, balance, alignment, or setup issues that deserve immediate attention.

Tires on a 2011 Infiniti G37 should be inspected regularly for tread wear, cuts, bulges, cracking, and air loss, especially if the car is driven spiritedly or spends long stretches parked. Staggered applications deserve extra attention because front and rear tires may wear differently and cannot always be rotated in the same way as square setups.

A good routine is to look them over during pressure checks and before longer drives, then inspect more closely whenever ride quality or steering feel changes. Low-use cars still need attention, since age and storage conditions can affect tire condition even when tread depth looks acceptable.
