Stop in for a cup of coffee

195/70/14 in the front. The total diameter is identical but the rears have an 8" wide tread while the fronts have a 6' wide tread (actual tread width, not section width)

Section width is 9" rear and 7.7" front
Just curious. I will be getting tires for my Duster soon. I'm going for factory appearance with whitewalls and wheel covers. Likely go 215/70/14 all around. But still looking at options.
