Here is comment from Likai as below:
"The F-18 1/6 main door opening width is 132mm, this size is scale. The tire must be inflated to correct diameter 126mm, so the clearance on each side is only 3mm.
In a long period storage, the tire will flat to 115 mm.
The main tire of F-16 1/5 is inflated to 143mm and 134 mm when flat. It's no way to fitted in a scale sized 1/6 F-18 main door."
