Goodyear EfficientGrip SUV 1st Generation: Provides long-lasting quiet driving, high comfort, excellent handling, and outstanding fuel efficiency. Goodyear EfficientGrip SUV 2nd Generation: Focuses on quietness, comfort, and wet performance, with improvements in noise reduction and comfort, but fuel efficiency is not mentioned. The following are the related details: Quietness: Closed tread groove design: Effectively reduces tire noise by minimizing lateral tread movement. Closed shoulder design: Prevents tread noise radiation, significantly reducing interior and exterior noise. Closed shoulder tread pattern: Reduces shoulder deformation and uneven tread wear, ensuring low noise levels throughout the tire's lifespan. Comfort: Optimized tire contact area and pressure distribution to minimize vibrations; enhanced tire structure for better shock absorption and cushioning. Performance: Uses a high-silica compound for superior grip. The Goodyear EfficientGrip SUV 2nd Generation is specifically designed for luxury SUVs as an upgraded version of the 1st generation, with a stronger emphasis on comfort and safety.
I remember the main differences between the first and second generations of the Assurance SUV tires lie in performance and comfort. The first generation had quite noticeable tire noise at high speeds, making long drives tiring for the ears, and its wet grip wasn't strong either, leading to skidding during emergency braking in the rain. The second generation upgraded the tread design with finer patterns and premium rubber materials, significantly reducing noise—now it runs almost silently. It also offers better grip on wet roads, shortening braking distances and improving safety. Fuel efficiency is slightly better too; on the same route, my average fuel consumption dropped from about 9 liters to 8 liters. In terms of durability, the second generation is more wear-resistant—a friend's tires still have deep treads after two years of use. Although the overall price is a bit higher, it's more cost-effective in the long run, so I'd recommend SUV owners consider upgrading.
