Romer1, I did a little research for you Toyo is a Japanese Company that has been around since 1945, they bought out the Cheng Shin Tire Co. of China in 2002. They have tire plants in just about every country. The M-143 that your asking about are made in Toyo's plant in Atlanta Georgia U.S.A. and there USA HQ is in Cypress, CA. The M-143 tires are a hard rubber truck tire. I got on a Toyo M-143 tire reviews RV Forum and they got outstanding reviews there, and they have a solid reputation around the World. If you decide to buy these tires they have a good RV tire care website toyotires101! Sounds like a good deal to me! Good Luck
