We replaced all tires on E631 on 08/22/2018 with Double Coin RLB1 Traction Tubeless tires while on a wildland fire assignment in Oregon. Shortly after replacement the engine was driven back to the home unit on the Hiawatha National Forest for the remained of the winter. At this point the tires were in good condition. Receiving a prescribed burn resource order for the Hoosier NF E631 made the drive to Bedford, IN. The following day at Bedford a firefighter operating the engine noticed a split in the sidewall of the passenger steering tire through to the wire on the sidewall. We had not contacted anything on the drive down to Indiana. The spot on the tire was hot to the touch after being driven on. After inspecting our other tires a spot on the passenger steering was found bubbled out and looked like it was ready to split as well. |
