I bought new YOKOHAMA RY215 in 7.00x15 (7R-15) from Tire Rack. Weight rating is 2,040 at 65-psi, 8-ply rated. Nice narrow tread, takes full lock turns on fresh, sharp concrete with virtually no scuff. Have 5,000 miles on them; temps on 100F day never above 125F (hot, 71-psi)(less than the new Michelins on the truck). This is a commercial service tire. See Yokohama site for info.
