What does a bigger gear ratio mean?
The higher the number the better the car will accelerate, but at the expense of high speed cruising.
Now for the confusing part of the story.
A high numerical gear ratio is called a low gear or low rear end, and vice versa.
Low gears give fast acceleration, high gears give better cruising..
Does changing wheel size affect speedometer?
Changing tire size is one of the most common things car owners do that can affect speedometer accuracy. That’s because larger tires cover more ground in one complete revolution. … This has a tremendous affect on your speedometer, which will now indicate a speed that is too slow by almost 13 percent.
What gear ratio is best for 33 inch tires?
So if our truck had 30-inch tires stock, and a 3.73:1 axle ratio, that calculation would tell us we need a 4.103:1 (which rounds off to the readily available 4.10:1) gear ratio to get us back to stock with 33-inch tires.
What’s the best gear ratio for highway driving?
Rear end gears (2.79’s, 3.00’s, 3.25’s, etc) are great for freeway driving, bit not good for 0-60 MPH or accelerating from a dead stop. Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc. Always remember, for very “give” there is a “take”.
Are 3.73 or 4.10 gears better?
Vice versa, if the gear ratio is lower it has worse acceleration but a higher top speed. So, by changing your gear ratio, no power levels are being changed, just the torque….WHICH GEAR RATIO IS FOR YOU?3.73 RATIO4.10 RATIOBetter gas mileageWorse gas mileageHigher top speedLower top speed2 more rows•May 12, 2020
Is 3.42 or 3.73 better?
The 3.42 is fine for towing smaller boats, plus you will get better gas mileage for everyday driving. If I were towing frequently on hilly roads, I might would go for the 3.73 for better gas mileage while towing, but the 3.42 should be fine with a 205.
Do larger tires lower gear ratio?
Calculating Effective Drive Ratio As you can see, the larger tires reduce your final drive ratio to 3.30—a measurable difference. You can also do this to determine the effect of smaller tires on your final drive ratio.
How much will my speedometer change with bigger tires?
Up-sizing or Down-sizing. Up-sizing, or installing a taller tire, will lead to a speedometer reading that is slower than your actual speed. This is because a taller tire will have a larger overall circumference, which will cause it to travel more distance per revolution than the original equipment tire.
Does higher gear ratio mean faster?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential.
How do you recalibrate a speedometer for larger tires?
Electronic SpeedometerDetermine the distance of the test drive needed to recalibrate your speedometer. … Press and hold the calibration button on the speedometer, start the vehicle and release the button.Press the button again and drive the distance prescribed by the speedometer manufacturer.
Will bigger tires hurt my transmission?
Increasing Tire Size Will Reduce Your Vehicle’s Effective Gear Ratio. The increased size causes the tires to rotate slower to cover the same amount of ground. … If you are running an automotive transmission this can cause some serious strain depending on the current gear ratio if you choose not to regear your system.
Do bigger tires use more gas?
For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.
