Curious, but doesn't running the pressures low down to 26-27lbs offer higher risk in damaging the rim when it contacts a pothole? Meaning that the tires will collapse under the hit where then the rim connects on the impact zone directly. I've been running my tires at 42 front and 44 rear. I'm not pushing the car around corners hard and would like to preserve the tread life over the life of the tires. I can see how lowering the pressure up front can help prevent understeer as well as give a softer ride. The road on my commute, highway 17, isn't all that bad, so the higher pressure isn't beating me up. I'll try to search, but wondering if anyone has data on the rolling efficiency with the tires at max 44 PSI vs the lower 26f/36r combo.
