The "R" on trailer tires stands for "radial," indicating that the tire's design includes radial ply construction. This information can be found on TireBuyer.com, specifically in their "Tire Tech 101" section, where they discuss tire size and type identification (https://www.tirebuyer.com/education/u...). The same information is also available on etrailer.com, within their "Tire Terminology and Definitions" page (https://www.etrailer.com/faq-tire-ter...).
