I'm going to ride motorcycle ( Ninja 400) with organized group tour from Chiang Khong, Thailand, to China. The trip will be on 5th December, 2018. I'm worried about Laos section. Last I heard was that roads in Laos have deteriorated very much. Would adventure tires( (trail) be recommended? I'd prefer to retain road tires for high speed riding on Chinese highway, but ready to change to something like Continental Trail Attack 2 tires, if that is needed
