Default Gear ratio differences

Does anyone know the difference in engine rpm between3:70 vs. 3:50 vs.
3:36. Gear ratios? I have P255/60-15” tires. I`m just curious as to the
Drop in RPM between the different gear ratios.

Thanks guys.

There are loads of gear ratio calculators out. Google is your friend.

Not trying to be harsh here friend, but that's fourth grade math that can be done on a calculator in about 15 seconds. Honestly, just put in a little effort.

75 mph your rpm is your rear gear ratio in direct, not OD.
