The video is back to back 20 minute sessions. The last session we let 12 # of air out of the tires. This brought them to our cold pressures, after they had already heated up. Based on the outer wear on the front tires, letting the air out was a mistake.
I need to listen to the video to see if there is a difference in the singing of the tires after we let the air out. Especially the sound on the oval, that is steady state cornering and driver input is less of a factor.
With those pressures we lightly corded the outside of the left front at Inde a couple of months ago. That is the reason I increased the neg camber.
I need to go back to paying attention to tires more than I have been.
