The G20 had been feeling a bit podgy of late so checking pressures I found the change to winter temperatures had lowered the pressures in all the wheels to 30 psi. (Michelin pilot sport ZP) but not enough to trigger the warning light. Putting the pressures back up to 33psi I was surprised the amount of difference the small change made to the ride and steering but also the reduction of speed decay on coasting. Will keep an eye on the pressure display to ensure they stay at that.
