Not necessarily. I put on 275/70-18s (~2720mm), after adjusting to get the speed accurate I ended up with 2550mm. This size seems to be within the tolerance and parksense works for me.

The default tire size for me was 2462. I emailed the developer of alfa and he recommend to revert back to that and increase in small increments to determine when the fault started to throw. By doing this I was able to determine the fault kicked in somewhere around 2560mm tire circumference...

I tried it again over lunch to no success. I did notice that under Parking -> Parktronics module there is a B222A - Vehicle Line Mismatch fault present that comes back after clearing. Once I switch back tire size to what was stock the fault clears. I may just have to settle with my speedometer...

I put on a set of Goodyear Duratracs off of 2020 Rebel (275/70/R18), but didn't see them in the list of available options, so I ended up measuring the tire with a level on top and calculating the circumference that way (2590mm).

Yeah, I did the ABS initialization, Static ECU Initialization, and Clearing Rolls Information. I tried it three times followed by setting the size back to stock and lost ParkSense every time I was on something other than stock. If you’ve successfully done it that gives me hope that I can get it...

I just got started with alfaObd on my 2020 Big Horn and was able to update my tire size to get the speedometer spot on, but lost ParkSense in the process. I know people were having this issue with the Rough Country speedometer calibration tool, but supposedly a software update fixed this on that...
