Steven Liu, vice president, product development, American Tire Distributors Inc., says the R/T segment is growing because of the “versatility an R/T tire brings to the table. “No official data shows whether or not the R/T segment is bigger than the other product segments” in the LT category “in terms of volume,” Liu notes. “While the A/T and R/T segments are currently close in volume, the R/T market is quickly catching up and in many cases outpacing A/T growth. “While the R/T market currently isn’t larger than the H/T and A/T segments, its growth rate surpasses both. While A/T tires still lead in overall volume, R/T tires are one of the fastest-growing segments.
