Mine isnt quite "stock", but on my 68 hardtop car I have Ralley wheels 15x7 and 275-60-15 with the inner wheel well trimmed. On the 68 converitble, I have 15x7 Ralleys and 255-60-15 with no mod to the inner side. Both are pretty close and are a bit of a trick to fit in when taking off or putting on.
