Frequently asked
What size tires does the Infiniti QX50 use?
235/55R19 on Pure and Luxe (19-inch wheels); 255/45R20 on Sensory and Autograph (20-inch wheels). Verify with your door jamb sticker.
What are the best tires for the Infiniti QX50?
Michelin CrossClimate 2 for all-weather capability. Michelin Primacy Tour A/S for OEM-equivalent premium touring. Continental CrossContact LX25 for efficient, quiet all-season use.
How do I know when my QX50 needs new tires?
Check tread with a quarter and look for uneven wear or sidewall cracking. Longer stops in the rain, a pull, or a new hum at speed all say it's time. On a luxury crossover, a worn or cheap tire also brings back road noise the QX50 was built to keep out — so replacing on time protects the ride as much as your safety.
How much should I budget for tires on an Infiniti QX50?
Budget for a set, not one tire, and expect luxury-tier pricing — the QX50's premium sizes cost more than a mainstream crossover, and larger factory wheels more than smaller ones. A local shop can quote your exact size installed, including mount, balance, and disposal. If it's all-wheel drive, keeping the four matched is worth the upfront spend.
