Infiniti G Tires — Fitment by Year

The Infiniti G series spans nearly two decades of rear-wheel-drive and all-wheel-drive sport-luxury sedans and coupes, from the early G20 and G45 of the mid-1990s through the G35 and G37 generations that defined the nameplate through 2013. Because the G lineup includes multiple distinct platforms, body styles, and drivetrain configurations across that range, tire selection requires attention to the specific model year and trim rather than treating the entire G family as a single fitment.

Tire sizing across the G series varies considerably by generation. Earlier models generally ran narrower, lower-profile fitments appropriate for a sport-compact profile, while the G35 and G37 sedans and coupes moved to wider, performance-oriented sizes with aspect ratios in the 45-to-55 range. Coupes and sport-trimmed sedans often carry larger diameter wheels and correspondingly low-profile tires compared with base or luxury trim levels on the same model year, so confirming your door-jamb placard size before ordering is essential.

For everyday driving, grand-touring all-season tires are the most practical choice for the G series. They balance the handling feedback these cars are engineered to deliver with adequate wet-weather traction and reasonable tread life. Drivers in regions with significant winter precipitation should consider a dedicated winter tire set — the G35 and G37 in rear-wheel-drive configuration are particularly sensitive to tire grip in snow and ice, and all-season tires are not a substitute for a true winter compound in those conditions. AWD variants of the G35 and G37 benefit from winter tires as well, since AWD aids acceleration but does not improve braking or cornering on slippery surfaces.

Sidewall and load rating considerations matter on these vehicles. The G series is a relatively heavy sport-luxury platform, and tires should carry a load index appropriate for the vehicle's curb weight and any added load from passengers or cargo. Ultra-high-performance tires with very low aspect ratios can sharpen steering response but will transmit more road noise and harshness into the cabin, which works against the refinement these cars are designed to provide. A moderate performance all-season or a grand-touring summer tire often strikes the better balance for most drivers. Speed rating should meet or exceed the OEM specification for your trim.

If you are considering a wheel and tire package that differs from the factory fitment — either a larger diameter or a different width — verify that the overall rolling diameter stays within roughly two to three percent of the original to avoid affecting speedometer accuracy and stability control calibration. The G series uses an electronic stability system that is sensitive to significant tire size deviations. Always cross-reference your specific model year, trim level, and drivetrain when confirming fitment, as specifications differ across the 1995-2013 range in ways that are not always obvious from the model name alone.
