Continental makes some excellent tyres, but the OE tyre on the 4/4 is not one of them. Its performance is acceptable, but not very good, on dry surfaces. The problem is that in other circumstances, you can switch from modest grip to zero grip without any warning. The splendidly-named Henry Catchpole, who is a highly competent driver, ran a 4/4 as his EVO magazine long-termer. He memorably described the Contis as "trailer tyres" .
I ditched my original Contis long before they were worn out and switched to Vredestein Classic. This tyre is far superior on both dry and wet roads..
Henry Catchpole ran that car in 2012?
He mentions the tyres here at 2 mins 10 secs. the characteristics seem similar to my current GT80 fitted!
