Training tyres are a great functional fitness tool for any gym. You can flip them, push them, roll them, pull them, lift them, jump over them, the list goes on. Unlike large tractor tyres these tyres are designed for a gym environment. The addition of handles means you can perform movements like the deadlift and farmers walks. Coated in a polyurethane leather means that they are extremely robust and built to last. These are sure to 'tyre' out any level of athlete.
