The tyre, wheel rim, and inner tube were also found to be in poor condition, increasing the risk of explosion - and no suitable assessment was completed to ensure the tyre could be inflated safely, the probe found.
A young farmer tragically died after a tractor tyre he was helping a colleague inflate suddenly exploded in his face.
The dad-of-one was trying to help fix the large tyre, which was being inflated at the time of the explosion at the Lancashire farm, run by partnership William Hesketh and Sons.
Joshua was helping one of the partners, Bill Hesketh, re-seat and inflate the tyre, Preston Magistrates' Court heard.
Hesketh was in the middle of inflating the tyre's inner tube when it suddenly exploded in the horror accident on May 7, 2021.
