If we do math... example:

Stock 19” Rear is 9”Rim w +44mm. So overall stack = (9/2 x 25.4) +44 = 158.3

I am looking at a 20” Rear 10” w +40 which based on formula = 167mm

That would put the rear wheel lip .355” out from stock wheel. Yes?

Same logic in front
R19 x 8 w +30 = 131.6mm

Option
R20 x 9 w +38 = 152 mm

Difference +.815”

Am I doing this right???
