Well, with the conti's you're gonna be in cruise control at about 5 mph
over the limit, probably correcting papers or yakkin' on the phone.
Fuel economy expected: about 5-10% better than EPA estimates.

With the yoko's, you're left foot braking and trying to get tire squeal
on every turn (and you take the route with the most turns to get
*anywhere*!) by accelerating into and out of it.  If you happen to get
stuck on a highway, every other vehicle becomes a bollard to be
negotiated as tightly, precisely, and quickly as possible.

Fuel economy expected: about 70-80% of EPA estimates, if you're lucky.
