My truck will mostly drive up to 55mph max. Maybe some time down the road I’ll get a NV4500.37” tire and 4.10 gears isn’t too bad, so long as your engine is in decent shape. Your talking 2400-2500 rpm at 65mph. I have 35” tires and 4.56 gears with a 4 speed manual (no overdrive) in one of my trucks. It is spinning nearly 2900 at 65mph which is screaming, but liveable within reason. If you spend much time off road you will appreciate the lower gear ratio since the 3 speed doesn’t have a deep 1st gear.
I have only 3 gears , but also have a granny gear.
