Tires spin without squeal when broken loose

I've noticed that anytime I break the back end loose and spin the tires, they just spin without any squeal. Having watched the vids of the car on YouTube, it seems easy to squeal the tires, chirp them into 2nd, etc....yet I can't get any sound out of my rubber when it's spinning loose.

What's up with this? I know tires need to be broken in a bit but I have 800 miles on them already. The absence of any tire squeal makes me wonder if I'm losing out on some grip as well. They just don't seem all that 'sticky'.

Here is some of the nitty gritty details:
6MT Touring Sport (19" stock sport wheels/tires)
Ambient temp: 45-65F
Tire temp: car driven roughly 10-30min prior to wheel spin
Tire/car mileage: ~800mi
Tire pressures: 35psi front and rear
Road: city asphalt and concrete

Any ideas?
