Just replaced the stock wheels and tires on 2019 Rubicon JLU 2.0T and went up 1 size on tires. Went from stock 285/70r17 to new Nitto Ridge grappler 285/75r17 c rated. tire size comparison chart shows only 3.4% difference in circumference. Is it really worth it to reprogram tire size with that little of change? Just did it friday and had only driven jeep 35 miles on stock tires and could not see any real difference. I know new tire/wheel combo weighs 100 lbs. Chart shows speedo will be off 2 mph to the fast side at 60 which I can live with. New tires are an inch taller.
