Wow!!! you are lucky you were still able to control the stop from 120! Ive never seen something like this happen apart from on really old trucks with bald tyres. Perhaps a manufacture fault? Only 5k km on them - i mean the tread still looks chunky and are basically new. Looks like you managed to save a rim out of it though so not all bad lol

Looks likes a nice trailer too - and RTT? how come you dont have the same mud tyres on your truck?
