"Rin" comes from some South American countries. I'm Puerto Rican, and we say "aros" for wheels. Mexicans use the same word, as far as I'm aware. We call tires "gomas", but Mexicans and much of Central America call them "llantas". However, some South American countries use "llantas" for wheels! I've heard Spaniards and some South Americans call tires "neumáticos", but that's a super formal word. Many South American countries also say "ruedas" for tires. Dunno what the Cubans say -- paging Dr.
