Get low, drive through the tire, and flip it over.
Lift with your legs and chest into the tire, never round your back to muscle it up.
Flipping a tyre starts as a deadlift-style leg drive, the quads pushing the ground away from a deep crouch, and finishes with the glutes extending the hips as you step in and shove it over. Because the load is awkward and shifting, the whole body has to coordinate, but the legs and hips remain the engine on every flip. It earns its place in strongman-style training and conditioning as raw, satisfying power work you cannot replicate on a machine.
One you can flip with crisp leg drive for repeats, not a one-flip maximum grind. If you have to fight and heave with a rounded back to move it, it is too heavy to train with. Speed and posture first, ego later.
Lifting it like a bent-over row with your arms and back. The tyre should rise because your legs drove through the floor with your chest pressed into it, then you flip your grip and push. Arms lift nothing here, they just connect you to it.
Explosive leg and hip power with a conditioning kick, quads driving off the floor and glutes snapping the hips through. It also builds full-body coordination against an awkward object, which is strength that transfers outside the gym.
