I am building the M4A3 75mm Gun version late production Sherman (Tamiya kit no 35250) The wheels have spokes on one side and are smooth on the other. The picture on the box cover shows the smooth side being used, but most builds I have seen have used the spoked side. There is an option to use either obviously. Anybody know which one is correct or does it really matter.This is a link to a picture of the kit and you can plainly see the smooth side has been selected.
