So let's take a look at running down the freeway using this same car set-up and numbers. If you aren't into drag or street racing and you live in an area where you mostly do freeway driving for extended periods of time, you won't want (or even care about) a low gear ratio for jack rabbit starts. You'll instead want something that'll get you better gas mileage and cruise down the highway at a decent RPM. So let's look at a couple of equations for determining what speed and RPM you'll be at for a given gear ratio and tire diameter. I'm going to use 70 MPH as our cruise speed with the same 28" tire diameter we used before. This is a slightly different equation so pay attention to the numbers. 70 MPH x the axle ratio you want to see about x 336. So 70 x let's try a gear set of 3.50's, x 336 = 82320. Now divide that number into the tire diameter which will give us the RPM at 70 MPH. 82320 28" = 2,940 so at 70 MPH with 3.50 gears and 28" tall tires you'll be at 2,940 RPM

Tak się zastanawiam czy axle ratio jest tym samym co rear and gears czyli przełożeniem głównym
