Hi,
I have a Wahoo Speed Sensor connected to my Garmin 935
Tire Circumference is set to auto - will a calculation be made or do I require a Garmin Speed Sensor?

It should, but why not just set it for better accuracy?
I'm having trouble accurately measuring Circumference whilst on the bike - seems to be a good 20mm difference when weighted or not. I am trying to ride in a straight line with Garmin auto calculating to get an accurate Circumference. However, after seting to Auto no estimate is displayed
Yes, it is 700x40 (2200mm) running at 60PSI
But when sitting on the bike this changes by at least 20mm rough measurements using tape measure and a dot of paint on tire
I could just enter 2180mm, however, hoping to utilise GPS over a few kms to get a good calculation.
My Wahoo App auto calibrates @ 2150mm but this seems a bit low, was hoping to see Garmin guestimation
Should the auto calculation be displayed?
I'm not sure if there's any notification, but after the ride you can check the auto-calibrated wheel size in the sensor settings.
