That’s why I run a 4.56 gear ratio with 35″ tires. This gives me decent fuel efficiency at highway speeds, and enough low end power to throttle through difficult obstacles. Below I’ve outlined a gear ratio chart that cross compares tire size to gear ratio for the ideal RPM.
Do I need to Regear my truck with 35s?
Yes, going to 35s you should definitely regear. And yes, the 4.10 to 4.86 is the proper range for 35s. You trade off will be fuel economy vs towing power. Being that your probably not going to be towing that much weight, you would probably be fine with the 4.10.
What gear ratio is best for highway?
If getting the best fuel economy is priority, then choose the lowest numerical number offered, such as 3.08, 3.23 or 3.31. This applies to highway driving; city driving mpg isn’t really affected by the axle ratio. If you do a mix of both, go with the “standard” axle ratio offered by the manufacturer.
What gear ratio is best for gas mileage?
If you just want the best mpg and never tow or haul a load, get the tallest (3.23-3.42) ratio offered.
What gear ratio do I need for 35 inch tires? – Related Questions
Which gear ratio gives more torque?
Gear ratios can be boiled down to a single statement: Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds and better fuel economy. Higher ratios mean the engine has to run faster to achieve a given speed.
What gear ratio is better for acceleration?
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.
Is 3.55 or 3.73 gears better?
PERFORMANCE: The larger the axle ratio number, the quicker the truck will accelerate. For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. Similarly, a pickup with a 3.73 axle ratio will be faster than one with 3.55s.
Are 3.73 or 4.10 gears better?
ARE 3.73 OR 4.10 GEARS BETTER? Use this rule of thumb: The shorter the gear ratio (higher number), the easier it will be for the vehicle to start moving and accelerating! This will, however, lower the top speed of the vehicle.
Is a 7.5 1 gear ratio good?
So, in the case of a baitcasting reel, a reel with a 7.5:1 gear ratio will retrieve 60 feet of line much more quickly than a reel with a 4.5:1 gear ratio. This principle is what causes anglers to say that 7.5:1 is a high gear ratio. In reality, though, it’s not higher, just faster to retrieve line.
When should I shift gear for best gas mileage?
The ideal spot to get the best fuel economy is when you are cruising on the road at high load (a wide-open or nearly-wide-open throttle) and low RPM. The throttle of the engine in this situation will be wide-open.
At what RPM is the most fuel-efficient?
Between 1,300 and 1,500 RPM
Do you lift off gas when shifting?
Release your foot from the gas pedal while you are shifting. Practice upshifting and downshifting while pressing and releasing the clutch pedal while the car is off. To come to a complete stop, you must depress the clutch to shift into neutral. Then, take your foot off the clutch.
Why is 55 mph the most efficient speed?
So, why 55? Well, it has to do with wind resistance, actually. It turns out that when it comes to wind resistance, at 30 mph wind resistance is four times as great compared to when a car is going 30 mph.
What freeway speed saves the most gas?
About 55 miles per hour is the optimum speed for most cars. Kick it up to 65 mph and you are 8 percent less efficient; at 80 mph you are 28 percent less efficient. Slowing down can also mean reducing your carbon footprint.
Does driving fast burn more engine oil?
Driving fast, especially in a sports car, can burn gas more quickly. And while the result isn’t as drastic, driving fast burns oil as well. However, this is typically only true at high RPMs, and the burning of oil is negligible unless you have other engine issues.
How can I increase my gas mileage by 70 percent?
How to Increase Your Gas Mileage by 70 Percent

Does running AC affect gas mileage?
As a general answer, a Consumer Reports study found that, yes, running the AC does reduce gas mileage. Here are some tips to help you balance your fuel consumption with comfort. Generally, the air conditioner uses gas, so use it wisely.
What mods increase gas mileage?
