Infiniti FX50 Tires — Fitment by Year

The Infiniti FX50, produced from 2009 through 2013, occupies a specific niche in the performance crossover segment. Built on a rear-wheel-drive-biased platform with available all-wheel drive and powered by a 5.0-liter V8, the FX50 was engineered to prioritize driving dynamics as much as utility. This character has direct implications for tire selection — the FX50 rewards tires that can handle high lateral loads in corners while still providing the ride quality expected of a luxury vehicle.

The FX50 was originally equipped with staggered fitment from the factory on many trims, meaning the rear tires are wider than the fronts. This setup optimizes traction and handling balance but complicates tire rotation and replacement. Shoppers should confirm their specific year and trim configuration before purchasing, since staggered fitments typically require separate front and rear tire sets and do not allow standard cross-rotation patterns. Verifying the exact OEM tire size on the door jamb placard or owner's manual is the most reliable starting point.

For daily driving in mixed conditions, a high-performance all-season tire in the appropriate speed and load rating is the most practical choice for this vehicle. The FX50 carries significant curb weight, so maintaining the correct load index is important — do not downgrade the load rating when selecting replacement tires. Speed rating is equally relevant given the vehicle's performance orientation; a tire rated at least V (149 mph) or W (168 mph) is consistent with the original fitment category and preserves the intended handling envelope.

Drivers in regions with significant winter weather should consider a dedicated winter tire set mounted on a second set of wheels. Because the FX50 uses staggered sizing on many configurations, a non-staggered square setup (matching front and rear sizes) is sometimes chosen for a winter wheel-and-tire package to simplify rotation. If you pursue this approach, confirm the chosen size clears the front calipers and suspension components, as the FX50's front brake package is substantial. A tire retailer or fitment specialist can verify clearance before you commit.

All-terrain tires are not a natural fit for the FX50. Its suspension tuning and low ride height are calibrated for pavement, and all-terrain tires would compromise the on-road handling characteristics that define the vehicle. If light gravel or unpaved roads are occasionally part of your driving, a capable all-season tire handles those surfaces adequately without sacrificing the FX50's road manners. Noise levels also matter on a vehicle in this class — touring-oriented performance all-season tires generally offer a quieter, more refined ride than aggressive tread patterns.

Because tire availability and sizing have evolved since the FX50's production run, always cross-reference the exact size, load index, and speed rating from your door placard against current tire options. Trim levels and optional equipment packages could affect OEM specs even within the same model year, so confirming the specifics for your individual vehicle is the safest approach before placing any order.
