Vehicle model
Infiniti FX/QX70
The FX, renamed QX70 in 2014, is a mid-size luxury crossover-coupe produced from 2003 to 2017 across two generations. A pioneer of the genre, it pairs a tall, muscular body with a coupe silhouette and a decidedly sporty drive, making it an atypical SUV aimed at buyers seeking style and dynamism rather than maximum space. The first generation (FX35/FX45) introduced the concept as early as 2003, followed by a more refined second generation (FX35/FX50) from 2009, renamed QX70 for the market. It is a vehicle sought after by enthusiasts for its character. On the tire and wheel side, the FX/QX70 runs large wheels (often 18 to 21 inches) and low-profile tires poorly suited to harsh winters: a dedicated set of winter tires, sometimes in a reduced diameter, is strongly advised in Quebec.

Tires and wheels
Tire and wheel compatibility
Les Infiniti modernes, surtout les VUS (QX50, QX55, QX60, QX80) et les berlines sportives (Q50, anciennes G), montent généralement des jantes de grand diamètre, souvent de l'ordre de 18 à 22 pouces selon le modèle et la finition, avec des pneus à profil relativement bas. L'entraxe (bolt pattern) le plus fréquent sur la base Nissan est de type 5 trous, à vérifier précisément selon le modèle et l'année. Au Québec, où les pneus d'hiver sont obligatoires, il est judicieux de prévoir un second train hivernal, parfois sur des jantes de diamètre inférieur pour réduire le coût et améliorer la motricité. Confirmez toujours la dimension exacte inscrite sur la portière du conducteur avant d'acheter pneus ou jantes.
