国外发达的国家已广泛使用子午线轮胎，我区能否推广使用此种轮胎，进行了子午线轮胎和斜交轮胎的对比试验研究。通过装用子午线轮胎作轮胎报废里程、轮胎翻新率、车辆油耗、轮胎磨耗、轮胎费用等试验，结果表明，子午线轮胎耐磨、行驶里程高，节油效果明显，安全舒适等。 Developed countries abroad have extensive use of radial tires, our region can promote the use of such tires, the radial tire and bias tire comparative experimental study. The results showed that the radial tire wear resistance, high mileage, fuel-efficient effect is obvious, safe and comfortable and so on through the use of radial tires for tire scrap mileage, tire retreading rate, vehicle fuel consumption, tire wear, tire costs and other tests.
