I am currently planning to convert the Tamiya 1533 LRDG patrol car to its 1311 little brother. I am aware that the wheels were smaller but am trying to understand by how much.
The LRDG website provides some great information but at the same time not quite enough.
The 1533 wheels are quoted as 10.5x 20" and the 1311 at 7.5x 17".
What do these numbers mean, I am trying to work out wheel diameter, tyre diameter and tyre width?
Once I know that I will then have to work out how to make them but that is the next problem!
