17 Μαρ 2023 · There are three elements involved in determining the best gear ratio: engine rpms, vehicle speed, and tire diameter. Below is a gear ratio chart showing what your engine RPMs would be at 65 MPH based on your tire diameter and differential gear ratio in third gear (1:1 transmission ratio).
23 Φεβ 2024 · The proper rear-end gear ratio can be selected using the following simple formulas whether using a direct-drive (1to1) or overdrive (usually 30%) transmission. FIGURING TIRE DIAMETER (Height) FORMULA: Tire Size / 25.4 x Aspect Ratio x 2 + Wheel Diameter = Tire Diameter in Inches (Height)
Use our simple Gear Ratio Calculator to quickly find the correct gear ratio for your ring and pinion gear set. Save yourself the headache and let us figure out your ring-and-pinion gear ratio! Select the value you want to solve for. For the Tire field, enter your tire diameter in inches.
Use our Differential Gear Ratio Calculator page to determine the best ring and pinion gear ratio for your vehicle. Installation of the correct ring and pinion gear ratio will help optimize performance, fuel economy and overall driveability.
Rear end gear ratios can be boiled down to one statement: higher ratios – i.e., with lower numerical value – give better acceleration/torque and lower ratios yield to better fuel economy and higher top speeds.
The rearend gear ratio refers to the relationship between the driven gear (ring) and the drive gear (pinion), and is easily calculated by dividing the ring gear tooth count by the drive gear tooth count.
4 Οκτ 2024 · Understanding rear end gear ratios is crucial for anyone interested in the performance and efficiency of a vehicle. The gear ratio between the transmission and the wheels ultimately determines how an engine’s power is used to turn the wheels.
