Contact patch area calculator (and much more)
 

I thought I saw this link here before, but couldn't find it. So I'm gonna leave it here in case someone needs it.

I'm thinking larger contact = more even pressure across the area = better grip and less wear.

I'm currently playing with tire sizes to get for the rims that I already have. It's depressing that most of what I'm considering produces a contact patch area less that Primacy's on stock rims ;)
Now, the compound is gonna be better...
