Thanks Bob. Do you have strong opinion on the tradeoffs 65 vs. 60?:

225/60/R15 - sidewall height of 65 /146.5 aspect ratio (83.5" circumference)
225 /65/R15 - sidewall height of 60 /135 aspect ratio (80.5" circumference)

I want to get to lower the height of car a bit and squeeze in a meatier tire (which I was able to do on my 68').

Full disclosure that I am going into the 14x7 to 15x7 wheel upgrade to simplify finding tires to fit longer term.

Thanks.
