The only difference between the stock tire and the tire the OP listed is the aspect ratio. The 60 versus the stock 70. The 70 would be the taller of the two tires, measured from the ground to the top of the tire. BUT sometimes the aspect ratio affects the overall sidewall width too.
I used to check the Dennis Kirk catalogs when I needed specific info on tires, they had really good tire charts and gave inflated tire dimensions. I haven't looked into Kirk in a long time so don't know if they still have that feature.
