Just had a run to Wales and back in them. Much quieter on the road than I would have thought. Seemed well behaved too, although I didn'thave any "incidents" to test them.
Off road, can't really comment. It was far too hard under the wheels to need any tread. Wales seems to be about 20mm of soil, then hard rock underneath. So on the lanes we did, we were driving on rock 99% of the time.
That's my 2p worth. So far very pleased.
Try Sowden tyres for good prices and top service.
