So instead of the tire pivoting cleaning around the pivot-point, it is now "wiping" around it. Effectively, you're swinging the tire to turn instead of spinning it in one spot.

Of course, stickier rubber also contributes, but it's mostly the scrub radius.
I was afraid this might be the cause. Which can only be fixed by changing to rims with correct offset.. but I love the looks of these rims..

There's only 5mm difference between stock offset and the Rotas, is that truly enough to make the steering so much heavier? That's less than a quarter inch...
