LT275/65R18 Cracks the Top 10 OE Sizes List

Feb. 26, 2019

Size LT275/65R18 finally made it into the Top 10 list of most popular replacement light truck tire sizes. It replaced LT285/75R16 as the 10th most popular replacement LT size.

That is not surprising, given that LT275/65R18 has been one of the Top 10 original equipment light truck tire sizes for more than 10 years. The only questions is, why did it take so long to crack the Top 10?

According to the preliminary edition of the latest U.S. Tire Manufacturers Association (USTMA) Factbook, size LT245/75R17 remains the most popular OE size -- it has been No. 1 for the last eight years.
