Hi Chalk 2,
Interesting, hope they might be better than the Karoo 3�s.
They were hard wearing but leathal on a wet road.
Part of the reason is the profile and also mine were 3-4 years old, really hard wearing.
Loved the Karoo and Karoo 2�s.
Using an electric plane to take a small amount off the older surface rubber helped; I currently use TKC-80�s now which seem to handle better off and on road, but wear a lot faster.

What tyres are you currently running?
