Steam Catapult track of HMAS Melbourne is not a problem for single nosewheel tyre of the A4G Skyhawk. All A4G tyres were about double the air pressure (about 300 psi?) - compared to land - for carrier ops, arresting and catapulting. This could be a problem when landing ashore on short wet NAS Nowra runways, after being catapulted from the ship (and don't forget to arm the spoilers - not used onboard).
