Not true. Here's the math:
245/35/19:
19" wheel = 482.6mm
sidewall = 245 x 0.35 = 85.75mm
total diameter = 482.6 + (85.75 x 2) = 654.1mm
285/30/19:
19" wheel = 482.6mm
sidewall = 285 x 0.30 = 85.5mm
total diameter = 482.6 + (85.5 x 2) = 653.6mm
255/30/19:
19" wheel = 482.6mm
sidewall = 89.25mm
total diameter = 482.6 + (89.25 x 2) = 661.1mm
The 245/35 and 285/30 are within 0.5mm of each other. the 255/30 is 7mm larger.
