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.
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.
If by wheels you mean the steel rims, most Catalinas were equipped with 14 inch wheels. You can increase the size of the wheels, but that requires buying different tires. Often times changing the wheels and tires from stock will require calibrating the speedometer. A larger tire spins fewer times per mile which causes the speedometer to indicate a slower speed. A change from 14 to 15 inch wheels won't make a huge difference in speedometer error (8%) unless you are driving at a very high rate of speed. As speed increases, error increases. Mounting wheels above 15 inches runs the risk of a speeding ticket unless you have a GPS unit that can be used as a fallback speedometer.
Yes, they will fit. Be aware that if the wheels are not the same diameter your speedometer will be off unless you change tires to compensate.
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.
keep the tire ride height the same.
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.
try checking the connection between the speedometer and the engine or wheels
they used to be on the front wheels?
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.
yes 17 in. wheels will work on your sierra i have 15 in. and all i had to do was calibrate the speedometer
Well both of those are from sensors in the wheels so maybe make sure you are using the correct wheels.
