You can make your rpm basically whatever you feel is appropriate by changing gears and / or adjusting speed. You don't honestly think a 4.10 vs 3.55 gear ratio is going to make a difference in glazing brakes if the driver is using his equipment property do you?

Actually lower differential gears will bring all the final gears closer together giving you more options and able to pick a more appropriate gear for your situation. It's a bigger deal when you are going up hill but down hill it helps too.

If you are alone on the road then you can pick whatever speed is appropriate for your rig/ situation but in traffic your speed is often dictated by the traffic around you. This is where the lower gears will really help.
