How different it is to ride with same gear ratio with 26″ and 28″

Asked by: Landon Meyer

Assuming wheel with tires have an actual diameter of 28″ and 26″, a 28″ wheel gives 28/26 = 1.07 i.e. 7% higher gear ratio over a 26″ wheel.

Does gear size matter if ratio is the same?

There is more to the gearing on a bike than simply the size of the big ring. In short, size does not matter because it’s the ratios that are generated by each combination of the chainrings with the sprockets that are most important.

What gear ratio do I need for 28 inch tires?

Gear Ratio and Tire Size Chart

How much does tire size affect 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.

Do gear ratios make a difference?

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. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.

What gear ratio is best for fuel economy?

Best MPG ratio



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 speed?

In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears.

Do bigger tires raise or lower gear ratio?

When changing gears for taller tires, you are heading to a numerically higher gear ratio. The higher the gear ratio, the smaller the pinion gear.

What gear ratio is better for torque?

A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.

What is the best gear ratio for 1/4 mile?

In the quarter-mile, Fourth gear is equivalent to running a 3.79:1 rear gear. But shift into 1:1 Fifth gear and enjoy the highway cruising rpm of a 3.08:1 rear gear. The 60-foot times were exactly the same for both transmissions and no other changes were made.

Does higher gear ratio mean faster?

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.

How do I know what gear ratio I need?

Quote from video: What your new gear ratio needs to be you. Simply take the size of the new tire that you plan to install on your vehicle divide. It by the size of the old tire and multiply it by the stock ratio.

What does changing your gear ratio do?

Quote from video: The tire size and what you want to get out of it. So when you're talking about changing a gear ratio. Because you've got a lift kit and you've got your bigger tires on there and all of a sudden it

Does gear ratio affect horsepower?

A higher numeric axle ratio (4.11:1) keeps the engine running in the higher horsepower range, thus improving performance.

What is the best rear axle ratio?

The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy. This is a good ratio for the occasional towing or hauling individual. For a person who tows more often, and heavier loads, the 3:73 or 4:10 may be more appropriate.

How does gear size affect speed?

In a small/large gear set-up, when the small gear has made a full rotation, the large gear will not have yet completed a full rotation. Thus, the smaller gear makes more revolutions in a given time, rotating at a faster pace than the larger gear.

What happens when a small gear drives a larger gear?

If you use a small gear to drive a large gear, the large one will turn slower. fast speed, we use it to move the large one. gear turn more slowly.

Are bigger gears more efficient?

The gear ratio is exactly the same, the only possible difference is in the efficiency of the power transmission. Big/Big is generally more efficient, so it should be better for both, unless there is some reason that greater power losses in the transmission chain help “spinners”.

How do I figure out what gear ratio I need?

The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).

Does a higher gear ratio mean more torque?

Gear ratios are what engineers call “torque multipliers.” Higher numbers give more torque more quickly to allow better acceleration. Let’s compare that to, say, an early 1960s Ford truck transmission, with fourth gear at a 1:1 ratio, third at 1.69:1, second at 3.09:1 and first at a very short 6.32:1.

Do lower gears accelerate faster?

In general, you’ll want to keep this rule of thumb in mind: the lower the gear, the more power you have available. The higher the gear, the faster your engine runs! With both manual and automatic transmissions, you’ll generally move from lower to higher gears as you accelerate.

Can you have different gear ratios front and rear?

Yes. It is possible to have different axle gear ratios for the front and rear wheels of your car. However, the difference should not exceed the accepted range. There is a maximum accepted deviation between the front and rear axle gear ratios to keep your transfer case safe.
