I've actually never heard of these tyre before, as the other say, the tyres are the only thing that can save your life...more prominent in the wet, so basically if the car in front of you (on good tyres) brake hard, and you brake, despite leaving sufficient distance, it is likely you will hit them, at least judging by tyre tests and their wet braking distances between premium and budget.

Have a look here, even the differnce between the 'best' and the worst (midrange) tyres is 5 meters wet braking. I can't imagine the best and the budgets!
