Ironhorse i didn't have a problem with the tires and heat it was from the front axiles tires would tend to tip up nails and the second and last set of tires was always getting flats.
Always seem like i get flats in late summer when the grader stur up old nails,wire,objects and the ground surface being harder?:beatsme
With the 17.5 rims(one piece) tubeless tires i could usual just air them up and at least make the move then fix ,where you can't do that with tube type.
Plus the old split rims are a pain and dangerous to fix !!!!!! Just a couple reason i switched them,but heat and blowing tire wasn't an issue,but most of my hauls are just short hauls:usa
