Vehicle model
Infiniti Q45
The Q45 is the flagship sedan that inaugurated the Infiniti brand in 1989. A large rear-wheel-drive luxury cruiser powered by a V8, it directly targeted the high-end German and Japanese benchmarks of the era. Three generations followed one another through 2006: the first (1989-1996), praised for its performance and based on the Nissan President platform; the second (1997-2001), more conventional, on the Nissan Cima base; and the third (2002-2006), with sharper styling and a more powerful 4.5 L V8. The Q45 then gave up its flagship role to the M sedan. It is today a prized collector vehicle. On the tire and wheel side, this large sedan ran touring tires on wheels of moderate diameter for the time; in Quebec, a suitable winter set remains essential on this kind of heavy rear-wheel-drive vehicle.

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.
