The speedometer reading differences should be negligible if you spec the tyres according to the manufacturer's manual because the tyre profile for a 15" wheel would have been fatter than that of 16" for the same car. The meter is calibrated to the inflated tyre mounted on the wheel and the reading is a close approximate of the actual speed only.
There are several things that one needs to take into consideration when switching from 17 to 26 inch wheels. The biggest thing to understand is that making this switch will have an affect on the speedometer by causing the speedometer to not have an accurate reading of your speed.
Do you have the correct size tires/wheels on the vehicle? Look on the driver's door post or in your owner's manual for the correct size. Incorrect size tires will effect the accuracy of the speedometer. If you are running the correct tires then the vehicle speed sensor (VSS) may need replacing.
Yes, as long as the hole pattern is the same. You should also check the offset, or how far the rim center is from the edge. You can keep the speedometer reading true by selecting 15" tires that have the same diameter as the 16" tires that you are replacing.
If larger wheels are used, the speedometer reading will be lower than the actual speed of the vehicle. This is because larger wheels cover more ground with each revolution compared to smaller wheels, resulting in fewer revolutions needed to travel the same distance.
The speed you read from your speedometer is called your "indicated speed." This value represents the speed at which your vehicle's wheels are rotating, not necessarily your true ground speed due to potential inaccuracies in the speedometer reading.
The speedometer measures the speed of a vehicle, which is a physical quantity related to the distance traveled and the time it takes to travel that distance. This involves concepts from physics such as velocity, acceleration, and motion. The speedometer works by converting rotational motion from the wheels into a linear speed reading.
The speedometer for a bicycle measures the speed at which the wheels are turning. By tracking the rotations of the wheels, the speedometer can calculate the speed of the rider based on the circumference of the wheel. This information is displayed on the speedometer, allowing the rider to easily monitor their speed while cycling.
Different size tires and wheels. The factory size tires and wheels are calibrated with the speedometer. If a different sized tires or wheels are put on the vehicle, the speed can be off.
There are several changes that happen when switching from 17 to 26 inch wheels. The biggest change that happens is that the speedometer does not accurately track the speed of the vehicle. Therefore you will need to have the speedometer readjusted.
Because when you look at the speedometer it is telling you your speed at that particular instant in time, it changes from instant to instant.
