Infiniti EX35 Tires — Fitment by Year

The Infiniti EX35 (2008–2012) is a compact luxury crossover built on a rear-wheel-drive-based platform shared with the G37. It combines sport-sedan handling dynamics with SUV versatility, which means tire selection plays a larger role in daily driving character than it might on a more utilitarian crossover. The tires you choose will directly affect ride refinement, cornering precision, and highway noise — all areas where EX35 owners tend to have high expectations.

The EX35 left the factory on 18-inch wheels across most trim levels, though it is always worth confirming the exact original equipment size listed on the driver's door jamb placard for your specific vehicle. The door jamb placard is the authoritative source for the factory-recommended tire size, load index, and speed rating. Do not rely solely on what is currently mounted, as the previous owner may have changed wheel or tire sizing.

Because the EX35 uses a sport-tuned suspension and is not designed for off-road use, all-terrain tires are not a practical choice for this vehicle. The majority of EX35 owners are best served by a high-performance all-season tire or, for spirited driving, a grand touring all-season. These categories balance year-round traction with the low road noise and responsive handling that suit the EX35's character. If you live in a region with significant winter snowfall, a dedicated winter tire mounted on a separate set of wheels is a more effective and safer approach than relying on all-season compounds in severe cold.

When selecting a replacement tire, pay close attention to the load index and speed rating. The EX35's sport orientation means the factory tires typically carry a higher speed rating — replacing them with a tire rated lower than the original spec is not recommended. Load index should match or exceed the OEM figure. Additionally, keep sidewall profile in mind: the EX35's ride quality is partly managed by sidewall compliance, so moving to a lower-profile tire than stock (e.g., dropping from a 55 to a 45 series) can sharpen steering feel but will also transmit more road imperfections into the cabin.

If you are considering upsizing the wheel diameter for aesthetic reasons and mounting a lower-profile tire to maintain the same overall diameter, be careful to calculate the total rolling diameter against the factory spec. A significant deviation can affect speedometer accuracy, stability control calibration, and clearance within the wheel well. Plus sizing by one inch (e.g., moving to a 19-inch fitment) is generally manageable if done with proper offset and load-matched tires, but verify fitment data specific to the EX35 before purchasing.

Always cross-reference your exact model year, trim level, and current wheel size before ordering tires. Infiniti may have used different configurations across the 2008–2012 production run, and aftermarket wheel changes by a previous owner can mean your vehicle no longer matches the original tire spec. Use your door jamb placard as the starting point and consult fitment data for your specific configuration to ensure you are selecting a tire that is both safe and appropriate for how you use the vehicle.
