Tank slapper comes from the motorcycle world.... front forks oscillating from side to side so bad that they and you slap the gas tank. Very scary and almost impossible to recover from on a motorcycle.
When I did my first HPDE, my instructor told me, after making a few braking/turning mistakes, that if I was in any car besides an e46, I would of been in the grass...
I'd say the Blizzaks are one of the best HP snow tires on the market. I found them very predictable on the 135... even with the softer sidewall
