https://www.stellamodels.com.hk/alum...u-p-10503.html Here's a good profile view of a typical rim for this type of tire. When I measure the stock Tamiya rims I get 47mm outer diameter and 44mm in the valleys on both sides where the tire rests. Maybe it would be a good idea to buy a set of cheap Tamiya rims for measurements. https://www.stellamodels.com.hk/5654...a-p-10104.html and https://www.stellamodels.com.hk/5654...a-p-10106.html
