Your car's speedometer is a vital instrument, providing real-time information about your speed. An accurate speedometer is a must for both safety and legal reasons. At Duffy's Auto Service, we offer speedometer services to ensure it is functioning properly.
Speedometers can become inaccurate over time due to wear and tear or after modifications to your car that affect wheel size or tire diameter. For example, after changing your tire size or wheels, our technicians will carefully inspect your speedometer for any signs of malfunction.
Speedometer Calibration
If your speedometer is inaccurate, we can use specialized equipment to calibrate it to ensure it displays your true speed.

If you suspect your speedometer is reading too high or too low, it's important to have it checked to be on the safe side. At Duffy's Auto Service, we use top-of-the-line equipment to diagnose and repair speedometer problems.

Why does my speedometer work but the odometer or other gauges don't?
When your speedometer works but the odometer or other gauges don't, the problem usually lies in the instrument cluster itself rather than the speed sensor.
Individual parts of the cluster can fail independently, which is why one reading can go out while the rest keep working. Bring your vehicle to Duffy's Auto Service in Saint Paul Park and we'll diagnose whether it's the cluster, the wiring, or a sensor behind the issue.
Will bigger tires or new wheels throw off my speedometer?
Yes, changing to a different tire or wheel size can make your speedometer read too high or too low, since it's calibrated to your original setup.
A larger diameter makes the car travel farther per rotation than the speedometer expects, so the displayed speed no longer matches reality. After a tire or wheel change, the professional
team at Duffy's Auto Service can recalibrate your speedometer so it shows your true speed again.
Can you fix a speedometer that jumps or reads erratically?
Yes, a speedometer that jumps, spikes, or bounces around can usually be repaired once we find the source.
Erratic readings often come from a failing speed sensor, a loose connection, or a cluster issue sending inconsistent signals. We're open Monday, Tuesday, Wednesday, Thursday, Friday, so call Duffy's Auto Service at (651) 459-9052 and we'll track down why your readings are unstable and get them steady and accurate again.
