The U.S. Tire Manufacturers Association has identified the top original-equipment manufacturer and aftermarket tire sizes in its latest fact book that covers the 2018 calendar year, according to a report on ModernTireDealer.com.
The top sizes of truck tires added to new trucks include 295/75R22.5 (28.4%), 11R22.5 (24.9%), 275/80R22.5 (13.1%), 225/70R19.5 (8.6%), and 11R24.5 (5.8%). These sizes have been the top five for the past four years.
The top replacement sizes include 295/75R22.5 (24.3%), 11R22.5 (22.3%), 11R24.5 (9.7%), 225/70R19.5 (7.4%), and 275/80R22.5 (6.9%). These sizes have also been the top five for the past four years.
Prior to 2015, size 275/80R22.5 was grouped with size 295/75R22.5 in the USTMA system because they had identical applications, said an association spokesperson. From 2015-2017, they were reported as two different sizes. In 2019 (USTMA Factbook 2020), the association will return to its pre-2015 reporting "to more fairly represent the full market for this application."
