Kym likes the Hankook Dynapro Mud Terrain 37x12.5 R17 for his Fuso Canter and Iveco Daily 4x4 campers, which have a fully loaded weight as high as 5500 kg / 12,000 lb.
"Hankook, BFG, Micky Thompson, Yokohama, Cooper, Goodyear, Falken, and Nitto Trail all offer a 37 x 12.5 R17’s so one has a vast choice."
