In about a week I will let you know if my experiment works out. I found a set of 15x7 rally IIs in a bone yard I am putting on a '67 rag top. The rubber is going to be 245 60 R 15s. I curently have a set of old keystone klassics with 225 70 R 15s and they clear the fender wells and sub frame just fine. I'll let you know how it turns out.
