I am picking up a '72 Spider next week and I have been told it has P400's on it. I am assuming I am going to have to replace them. I was looking at past threads and it sounds like the recommendation is to use a 195/65r14, 185/70r14 or a 205/60r14. When I started looking around and talked to TireRack they are suggesting a 195/60/r14 BFGoorich gForce Super Sport A/S (H/V rated) since I will be doing some auto crossing in it. It is OK to use a 60? They said in the other sizes I won't find a good sport tire? I went on other sites and that sounds about right. Any thoughts ... Help.
