Rear axle ratios and impact on towing
Suppose you have a choice between two axle ratios, say they are a 3.09 and a 3.45. And let's say the vehicle has an 8 speed transmission, so there's plenty of gear flexibility. Ok, so there's roughl...

Ok, I think I get it. If I get a 3.09 instead of a 3.45, that's about a 10% higher amount of wheel turn for each rev of the engine. And if the transmission wants to shift up at a given RPM each time, in theory (all other things being held equal) my acceleration span would be 10% greater while in the given gear before the next upshift. "In theory," because the system is always sensing variables like throttle, inertial and environmental resistance, etc.
