This reminds me of a post I put in the spectator section some weeks back never did get the answer I was looking for maybe some of you guys could tell me, I drive a 44 ton truck it has 16 wheels inflated to 110psi, I remember when being close up to a 737 looking at the main bogies and thinking how on earth can just 4 main wheel take all the weight of a fully loaded 737 from what I gather this can be 75.000kgs, I know there a 2 wheels at the nose but I would think the mains carry most of the weight but how on earth can such a small number of wheels carry that weight without even bulging.
