Four-wheel drive 225/45r18 + 255/40/r18. Runflat. For the city - a super option. Quiet and comfortable, even on a runflat there is no furious effect when driving over bumps. Excellent grip on the pavement, no hint of slip. But on ice - he passes (however, like other stickies). The main trouble is not to get out of the icy rut that occurs after the thaw in the yards.
