What is the tire specification of the new Bluebird?
2 Answers
Nissan Bluebird tire specification model is 215/50-R17. The function of car tires: Car tires are one of the important components of a car, directly in contact with the road surface and working together with the car suspension to cushion the impact during driving, ensuring good ride comfort and smoothness, ensuring good adhesion between the wheels and the road surface, improving the car's traction, braking, and passability, and bearing the weight of the car. The parameters of the tire represent: Production date, tire specification. Taking the 185/60r1789h model tire as an example, the tire parameters respectively represent: 185 indicates the tire width is 185mm; 60 indicates the aspect ratio of the tire section is sixty percent; r indicates the tire has a radial structure; 17 indicates the rim diameter is 17 inches; 89 indicates the load coefficient; h indicates the speed coefficient.
I remember when I first drove the new Bluebird, the original tire specification was 195/65 R15. This size was quite suitable for urban road conditions, ensuring a smooth ride without being too fuel-consuming. Later, when I went to the 4S shop for maintenance, the mechanic said this specification was designed to match the vehicle's suspension system. Changing the size randomly might affect steering sensitivity or increase noise. When I replaced the tires myself, I insisted on using the same specification, finding it cost-effective, and I also learned to check the tread depth—using a coin to measure it. If the wear reaches the marked level, it's time to replace them. I usually keep the tire pressure around 220 kPa, not too high in summer to prevent blowouts, and slightly lower in winter to enhance grip. I recommend car owners regularly check for cracks or bulges on the tire sidewalls and address any issues promptly for better safety.
