I have noticed a slight decrease in coasting ability so that does make perfect sense.
To the others: I do check tire pressure regularly. It's been a week or so but temps have't fallen that much in that amount of time. I'd guess them to be at around 40psi (from the 44 I usually run). I'll definately be checking again though.
