Apart from that they are lethal on standing water, drove on mine in rain on the M3 and struggled to keep the car pointing the right way doing 50mph in the slow lane. In the end I had to pull off at the services and wait for the rain to stop and the traffic to clear the standing water off the motorway.
My mate Chris who races a 09 Mini Cooper S on them reckons you can be ok in the wet if you keep plenty of heat in them but that's not really possible while stuck in traffic driving to work is it?

I have ran these in the summertime for the last 2 years on my Mk4 (not this year, though, as they're now very close to the depth markers!

), & Chris is absolutely right.......................... They're awesome in the dry, no worse than road tyres when damp, but are pretty scary on puddle ridden roads, IMO. They are good when warmed up, but like you said, is this possible on your commute?? Having said all that, as long as your careful in attrocious conditions, then I can't see the problem.
There is talk in the mags about the legislation on this type of tyre, being changed for sometime in 2011, IIRC.
