I was an airframe eng in the RAF, and worked on a big tail dragger, the Handley Page Hastings. When marshalling an aircraft into position before shutdown, we had to bring it forward until the tail wheel was straight. This was to ensure that the tyre was not distorted when at rest. Surely we all know that tyres distort when turning, and that can wear the sidewall. So why would you park an aircraft, or even your car, to the detriment of the tyres?
