Most people keep both tyres at the same pressure, or only slightly lower in the front, not nearly low enough to "equalize" contact patch size. I ride 85 rear/60 front, after I actually weighed the front & rear axle weights, however no-one else I know ever does that.
Rain washes the lube off the chain/cassette as the bike is being ridden, hard to ride a bike with newspapers on the back wheel.
Is there an emoticon of a little yellow face slapping his forehead?
