      Would Firestone be the manufacturer of the biggest tyres?

      Or I think dump truck tyres are bigger? Bridgestone or Michelin

        Fun fact (eh…more like barely recollected memory, likely to be wrong to some extent) -

        The tires on those big ass haul trucks are seriously dangerous as they reach end of life - a blowout on something that size is real violent. Far as I know, they’ve got a ton of instrumentation these days to keep track of conditions and remaining life, etc.

          On our mine we have a lot of systems to protect the tyres, and they are inspected regularly. Like if you overload your truck the truck will go automatically into creep mode to protect the tyres. We also have specialised services on site to inspect any damages and wear to ensure safe usage of the tyres, scrapping them way before the expected life span, usually at 50-60%. Repairs are also done but only if the tyres are not structurally damaged.

          But proper standoff distance usually prevents any people or machinery coming into any dangerous situation of a tyre blowing out. The real danger of these huge trucks, we have the 350 Tonnes version, its collisions, can so easily drive over almost anything without knowing, so that is why we have a very far standoff distance, 80-100 meters to ensure no one gets too close. Also we have a collision avoidance system where the truck switches off when anything gets nearby
