What is the 71r tire?
2 Answers
71r is a tire from the Bridgestone Potenza series, which is a track-capable tire. This high-performance tire offers strong grip, enhances cornering speed, and reduces braking distance. Tires are crucial components of a vehicle, being round, elastic rubber products mounted on various vehicles to roll on the ground. They directly contact the road surface and, together with the car's suspension, help mitigate the impacts encountered during driving, ensuring good ride comfort and smooth driving. Tires often operate under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes while in motion. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning properties.
I often encountered similar issues when repairing cars. 71R sounds like part of a tire size specification, where 71 is the load index number, indicating the tire can bear a maximum weight of approximately 345 kg, and R is the speed rating letter, representing a maximum speed of 170 km/h, similar to the rating on most summer tires for family cars. In practical use, you need to consider the entire size, such as the common 195/65R15, because just saying 71R can be confusing as it also involves the tire width and aspect ratio. I remember once my neighbor, Old Wang, mistakenly thought 71R was a specific model and ended up with mismatched tires, causing the car to feel unstable at high speeds. Later, I helped him check the label to confirm the load and speed ratings before resolving the issue. The key takeaway is to always cross-check the vehicle manual requirements when changing tires, as failing to do so can affect traction and safety.
