Does the R matter on tires?
R: Radial Tires R is for radial tires, the industry standard for most tires today. They have better road grip, lower rolling resistance for better gas mileage or electric range, ride comfort and durability than previous generations of tires. For drivers who want more off-road versatility than an All-Terrain can offer, an Extreme-Terrain tire has larger tread voids and softer rubber than an A/T, giving it better traction in mud, sand, unstable terrain, and even slush or snow.The tread of H/T tires is much smoother, with more shallow grooves than A/T tires, causing less friction with the road which makes for a smoother, quieter ride, lengthens the tire’s life and increases the vehicle’s fuel economy.All-terrain tires give drivers the versatility to tackle rugged landscapes as well as four-lane highways with ease. They are perfect for drivers who use their vehicle for daily commutes as well as weekend adventures in the outdoors.If your travels involve rough or unpaved roads, D tires provide enhanced durability and grip, making them a better choice. For primarily highway driving, R tires can offer a quieter, more comfortable experience. Additionally, think about the weather conditions you typically encounter.
