Just a small update.
I went with a set of 185 Yokohamas in the end.
So far I'm very pleased with them. The steering is much lighter as predicted by everybody.
Charging through the deluge on the M2 at the weekend was very confidence inspiring too.
The bonus is that the road noise and thus the interior noise has dropped so dramatically that it has now become much less of a hair shirt on long journeys. Overall, a result.
The only minor side effect is that the acceleration is reduced by wheel-spin if you are not careful but a small price to pay.
