What tires does the Infiniti Q50 use?
3 Answers
Infiniti Q50 uses 225/55r17 and 245/40r19 tires. In 225/55r17, 225 represents the tire width of 225 millimeters, 55 indicates the aspect ratio of 55, r stands for radial tire, and 17 means it can be installed on 17-inch rims. The following are the functions of tires: 1. Support the entire weight of the vehicle and bear the load of the car. 2. Transmit traction and braking torque to ensure the adhesion between the wheels and the road surface. 3. Reduce and absorb the vibration and impact force during driving, preventing severe vibration and early damage to car components.
I remember the Infiniti Q50's factory tire setup is quite professional, typically featuring high-performance summer tires. The specific models and sizes vary by year, with most Q50 models using 245/40R19, commonly from brands like Pirelli's P Zero or Michelin's Pilot series. These tires are optimized for grip and handling, making the car feel very stable in corners. The load index and speed rating are also important—the factory V-rating (up to 240 km/h) is sufficient, but don’t go lower to avoid safety risks. Remember to switch to appropriate tires with the seasons: summer tires like the factory ones work well in warm weather, while winter tires are necessary for icy conditions. For maintenance, I check tire pressure monthly, keeping it at 2.3-2.5 bar to extend lifespan and improve fuel efficiency. Don’t skip wear checks—replace tires when tread depth falls below 3mm. Avoiding hard braking can also prolong tire life, with factory tires usually lasting 40,000-50,000 km.
I've been driving my Infiniti Q50 for three years, and the original tires were Goodyear, size 245/40R19, which provided a quiet and comfortable ride. Later, when I changed the tires myself, I opted for a Hankook all-season tire because it's more durable and offers better value for money. Getting the tire size right is crucial, as mismatched sizes can affect balance, so I always check the manual before making a change. Keeping an eye on tire pressure is also important—I use a mobile app to monitor it and maintain around 2.4 bar for fuel efficiency and safety. When winter comes, I switch to snow tires since the factory ones aren't suitable for low temperatures, and the shorter braking distance helps prevent skidding. Driving habits should be gentle, as sudden acceleration increases wear. Tire lifespan is generally around 40,000 kilometers, and regular inspections help detect cracks early. Here's a tip: compare discounts across e-commerce platforms when choosing tires, but prioritize safety over cheap deals.
