Not so much for traction but tires are part of the spring package too. Radials have a different spring rate than bias plies. This is the secret that was given up by the successful teams at the Indy 500 the 1st year they ran on radials.

I had one of those moments too and witnessed it on 2 other cars. It is definitely the car oscillating on the tires/suspension in a weird way.
