if they have a smaller rolling diamter than stock, it'll shorten your gearing ratio. here's the math: (7000 * 6.51) / (4.08 * 1.00 * 88) = 126.92 mph if the Kumhos aren't true to spec and have a smaller rolling diameter... say... 6.40, 4th gear would top out at 125 mph I don't know why you're only doing 120 mph. It could be speedometer error, though.
