2024 RCSB 5.0 10 Speed 4X4 with 3.73 gears.
I leveled and then mounted 35X11.50/17 tires. 35s are 10% larger than the 31's (265X70/17) that came stock.
As EXPECTED, my speedometer was off by 10%. 40 mph on the dash was 44 GPS, 50 was 55 GPS, 60 was 66 GPS. I used a couple of GPS devices to double check those numbers.
As I had planned, I then swapped out the 3.73 gears for 4.11 gears. 4.11s are 10% lower than 3.73 so for any given RPM, the axles shafts should be turning 10% slower...
