B) These are probbibly 15\" rims not 16\" where are you measuring. the total rim diameter from rim edge to rim edge this is not the true rim measurement. rims are measured from bead seat, if memory servs type 1 & type 2 stock never came with a 16\" rim only steel 15\" from factory.Do you have a better description of these wheels. are they aluminum , width , what is the real diameter of these rims. design/style with this maybe some one can help you.
