No, larger tires do not affect the odometer. The size of the tire does not change the number of revolutions per mile.
One of the most frequently asked questions we get here at Tire Rack is whether or not installing larger tires will affect a vehicle’s odometer and, as a result, its fuel economy readings. The quick answer is “no,” but there are a few things to keep in mind when making the switch to larger tires.
First, it’s important to know that modern vehicles are equipped with what’s called a tire pressure monitoring system, or TPMS.
This system uses sensors to monitor the air pressure in each tire and will alert the driver if any tire is significantly low on air. When switching to larger tires, it’s important to make sure that the TPMS sensor can accommodate the new size. If not, you’ll need to purchase an aftermarket TPMS kit that’s compatible with your new tires.
Second, while installing larger tires won’t affect your odometer readings, it can have an impact on your fuel economy. That’s because bigger tires typically have wider treads which create more rolling resistance than narrower ones. As a result, you may see a slight decrease in fuel economy after making the switch to larger tires.
However, this decrease is usually less than 1%. So unless you’re extremely concerned about every last mile per gallon, don’t let this deter you from installing those bigger wheels and beefier treads!
How Tire Size Affects Speed
Odometer Difference With Bigger Tires Calculator
If you have ever wondered if there is a difference in the way your car’s odometer reads with different sized tires, wonder no more! There is in fact a difference, and it can be easily calculated using our Odometer Difference With Bigger Tires Calculator.
Here’s how it works: simply enter the original tire size and the new tire size into the calculator, click calculate, and voila!
You’ll instantly know how many miles per hour faster or slower your car will go with the new tires.
This information can be extremely useful when deciding whether or not to switch to bigger tires. For example, if you frequently drive on the highway and are looking for a way to improve your gas mileage, bigger tires may not be the best option since they will cause your odometer to read higher speeds than you are actually going.
However, if you do mostly city driving and are looking for a smoother ride, bigger tires may be just what you need.
So whether you’re trying to save money on gas or improve your ride quality, be sure to use our Odometer Difference With Bigger Tires Calculator before making any decisions!

How Do You Calculate Odometer With Bigger Tires?
Odometer calibration is the process of resetting a car’s odometer to zero miles. This can be done for a number of reasons, such as when changing the size of the tires on the vehicle. When changing tire size, it is important to recalculate the odometer so that it accurately reflects the distance traveled by the vehicle.
There are a few different ways to calculate odometer with bigger tires. The most common method is to use an online calculator. These calculators take into account the new tire size and circumference, as well as the old tire size and circumference, to determine how many miles have been added to the odometer reading.
Another way to calculate odometer with bigger tires is by using a mileage chart. These charts are available from most auto parts stores and list various tire sizes and their corresponding circumferences. Using these two pieces of information, you can determine how many additional miles have been added to the odometer reading.
Once you have determined how many additional miles have been added to the odometer reading, you can reset it accordingly. In order to do this, simply subtract the number of extra miles from your current reading on the odometer. This will give you your new zero point for future readings.
How Does Tire Size Affect Mileage?
Tire size can have a significant effect on fuel economy. In general, wider tires are more efficient than narrow ones because they have less rolling resistance. This is because a wider tire has more contact with the ground, which makes it easier for the tire to roll.
Wider tires also tend to be lighter than narrower ones, which further reduces fuel consumption.
Fuel economy is also affected by the inflation pressure of the tires. Tires that are under-inflated have higher rolling resistance and thus consume more fuel.
Conversely, over-inflated tires will result in less contact with the ground and will also lead to increased fuel consumption. Therefore, it is important to maintain proper tire inflation in order to maximize mileage.
There are other factors that can affect fuel economy as well, such as tire tread depth and wheel size.
Worn-out tires will have greater rolling resistance than new ones, while larger wheels can make a vehicle’s engine work harder and thus use more fuel. However, these effects are generally small compared to those of width and inflation pressure.
Conclusion
Many people believe that having larger tires on a vehicle will cause the odometer to show less miles than it actually traveled. However, this is not the case. The size of the tires does not affect how the odometer works and only displays the number of miles that have been traveled by the car.
