The INFINITI Q50 is a sport-focused luxury compact sedan that punches above its price in driving dynamics — especially the Q50 Red Sport 400 with its 400-horsepower twin-turbo V6. Tire choice follows the trim level: quiet touring for the base and Sensory, aggressive summer or sport all-season for the Red Sport.
INFINITI Q50 tire sizes by trim
The Q50 (2014 to present) uses 225/50R18 on the base Pure and Luxe trims (18-inch wheels), and 245/40R19 on the Sport, Sensory, and Red Sport 400 trims (19-inch wheels). Some Red Sport 400 configurations come with 245/40R19 front and a slightly different rear sizing on sport suspension packages — verify on the door sticker.
The Q50 is available in RWD or AWD. RWD models in the Red Sport 400 put all 400 hp through the rear tires — the right tire compound matters significantly for traction and rear wear rates.
Best all-season tires for the Q50 base and Sensory
Michelin Pilot Sport All Season 4 — the top pick for Q50 owners on 18 or 19-inch wheels who want both sport feel and all-weather capability. Available in 225/50R18 and 245/40R19. Strong wet braking, low road noise, and treadwear ratings around 500.
Continental PureContact LS — the quietest all-season in Q50 sizes. Best for owners who prioritize the Q50 touring character. Very smooth on rough pavement with strong wet weather scores. Available in 225/50R18 and 245/40R19.
Bridgestone Turanza QuietTrack — strong quiet touring option in 225/50R18. The right pick for Q50 owners who spend most time on highway.
Best summer and performance tires for the Q50 Red Sport 400
Michelin Pilot Sport 4S — the benchmark summer tire for the Red Sport 400. At 400 hp from a RWD or AWD platform, the Q50 Red Sport rewards a max-performance compound. Available in 245/40R19. Exceptional dry grip and predictable near-limit behavior.
Continental SportContact 7 — strong direct competitor to the PS4S in 245/40R19. Competes closely with the Michelin in independent test comparisons. Choose based on availability and price.
Goodyear Eagle F1 Asymmetric 6 — a sport-touring middle ground between the PS4S and a standard all-season. Better everyday durability and all-season usability than the PS4S at a lower price. A good choice for Red Sport 400 owners who want a single tire year-round.

Does the Q50 AWD need all four tires matched?
