Here are a few little graphs I put together for a few different people to compare the different measurements of a few select size tires.
First up is a comparo of a select few 255/35/18 and 265/35/18
all tires listed in this graph are a 35 profile and 18″ diameter
Measuring Width is the wheel width that was used when measuring Tread width and Section width. Both of tread width and section width change with wheel width. More on this in a future article.
