The small footprint of the bar grip tread makes them perform poorly on sand. Even in the 1930s, 'balloon' tyres with wider treads, smaller tread patterns and lower pressures, were available for desert use. [5] [6] The poor water clearance of bar grips may limit their performance on very wet mud.
The chief reason for tire replacement is friction from moving contact with road surfaces, causing the tread on the outer perimeter of tires to eventually wear away. When the tread depth becomes too shallow, like for example below 3.2 mm (4/32 in), the tire is worn out and should be replaced.
Aircraft tires generally operate at high pressures, up to 200 psi (14 bar; 1,400 kPa) for airliners, [2] and even higher for business jets [citation needed].The main landing gear on the Concorde was typically inflated to 232 psi (16.0 bar), whilst its tail bumper gear tires were as high as 294 psi (20.3 bar).

The Tweel airless tire design. The Tweel (a portmanteau of tire and wheel) is an airless tire design developed by the French tire company Michelin.Its significant advantage over pneumatic tires is that the Tweel does not use a bladder full of compressed air, and therefore cannot burst, leak pressure, or become flat.
The tundra-style tire has been independently invented at different times and places. In North America its post-World War II invention is credited to Canadian Welland Phipps, [1] potentially inspired by the Goodyear Tire & Rubber Company's pre-World War II development of their own, similar low-pressure "airwheel" as a complete wheel-rim and tire set — said to be of the "Musselman" type from U ...
