a 305/35 is TALLER than a 285/35 . . The "middle" number is the "percentage" of the tread with that equals side wall height, so.
35% of 305mm = 106.75mm or 4.2", 2 sidewalls plus rim diameter = 26.4"
35% of 285mm = 99.75mm or 3.9", 2 sidewalls plus rim diameter = 25.8"

He is %100 correct......... if youve never heard of it before i guess you dont deal with car stuff very often do you....????? The middle number is called the aspect ratio..... the percent of the tread width that is the sidwall height.
