What is the standard for the rear tire of the Tianlongxing scooter?
2 Answers
Tire standards refer to the section width and the percentage of the aspect ratio. Tire Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are usually installed on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance. Tire Performance: Tires are often used under complex and demanding conditions. While driving, they endure various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance. Additionally, they require high wear resistance, flexibility, and low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, highlighting the significant demand for rubber in tire manufacturing. Tire Specifications: Specifications are the geometric parameters and physical performance indicators of tires. Tire specifications are often represented by a set of numbers, where the first number indicates the tire section width, and the second number indicates the rim diameter, both measured in inches.
I've been repairing motorcycles for nearly 20 years, so I'm the most qualified to talk about the rear tire of the Tianlong Star. It originally comes with tubeless tires, usually in the specification 100/90-10, and maintaining a tire pressure around 2.5 bar is optimal. However, this depends on the specific model year, which can be checked on the tire sidewall and the vehicle manual. Both overinflation and underinflation are problematic—too low and it's prone to bulging, too high and the grip suffers. Don't overlook the numbers and letters on the tire sidewall; for example, a load index of 65 means it can handle 290 kg, and a speed rating of L corresponds to a maximum speed of 120 km/h. I recommend checking the tread wear every 5,000 km—the small triangular indicator on the sidewall points to the wear limit. Don't wait until it's completely worn out to replace it, as it becomes especially dangerous in rainy conditions. When buying new tires, don't just go for the cheapest option; choose a reputable brand with deep treads—it can shorten braking distance by up to 2 meters.
