Absolutely outstanding! Brilliant modelling and also excellent photography!
Another Tip for the tires (that's how I bulge Aircraft-tires all the time

), as "ironing" didn't work out for me either:
Heat up a pan with a bit of water on the oven and then gently push then tire in the water against the pan's bottom - the water will help the tire not to melt and you can work it longer to create a nice bulge. Works perfectly for me...
