I understand going larger on replacement tires will throw the speedometer off a little, but I'm wondering if anyone has ever had theirs recalibrated? Can you do it yourself? I didn't find anything in the thread search and I'm by no means an expert on it.
Speedo Calibration

I run 18s on front and stayed with 20 on back 305 30zr20. No recalibration needed. How big do you want to go?
-
I went with a bigger tire on the back and my speedo is off about 3 mph -- I don't think I'm going to bother recalibrating it

What size tire? That's critical information.

Actually, I checked into this a couple years ago. (Maybe here or the other dark site.) Speed sensors are located in the front wheels, not the rear or transmission. I could find no way to recalibrate at that time.
Maybe Dave@DDMWorks cracked the code when he made his new code reader?

Thanks to everyone for the input. I'm still running stock Kendas with only 10,000 miles on them and they're in great shape, however, when comes the time for replacements, I want to take it up a notch and have a little more profile between me and the road all the way around. There's a fella on here that posted a photo of three magnificent looking tires that I want. I believe they were Michelin tires, but I'm still searching through the gallery trying to find that photo. All I remember was the tires were sitting in his garage and his cap was sitting on top of one of them... lol So, anyway, if this only drops the speedo by about three mph, I probably won't bother with recalibration. I was just curious how difficult, or expensive, it would be and if anyone had ever done it.

I went with 22s all around and honestly don’t see too much change in speed and I’m scratching my head on that one

If you run with a GPS check the mph there... A friend I ride with has 20 inch wheels all the way around and he is off 2 or 3 mph. Be nice to LEO when he stops you.

When I do rides with my HOG group most of us are connected through an intercom system. Speedometers are close but still all over the place. The GPS units have proven to be very reliable. My slingshot speedometer has always had a high reading. 70 is actually about 67.

I use a speedometer app on my phone that has huge letters. I have a hard time seeing the dash readings.

The factory computer can only be set, by the dealer's Monkey Wrench diagnostics computer, to recognize the two factory size front/rear tire combo's.

I remember seeing speed correction decals that could be inserted inside the speedometer display for motorcycles to correct the built-in under display of speed for Japanese bikes, among others. This required disassembly and reassembly of the speed gauge. I had thought about designing a speed correction overlay that could be placed on the outside of the display, avoiding the disassembly/reassembly. I decided it was just easier to mentally apply the speed correction in my head, but placing an overlay over the display should work for any vehicle where the driver is basically sitting directly in front of the speedometer. The overlay won't correct any odometer discrepancy, but should correct the speed display.
This method would require a somewhat opaque self-stick plastic with the Speedo markings inboard from the area blocking the stock speedo numbers or the corrected speedo numbers might be placed over the stock area, but with some type of opaque color blocking all but the corrected speedo numbers. No idea if the stock speedo lighting will still provide enough illumination using a corrective overlay.

You can do your own speedometer recalibration easily with a bottle of white out and a black sharpie

Shatneyman welcome back old friend🍻good to see you posting. Hope all is well and please keep your selfies to yourself 🤣😂

Btw, mine are factory size, and about the same 3-4 mph off above 50 or so. Use Garmin on board for better accuracy.
