Vehicle - 2012 Hyundai i30, petrol, hatch.
Driving conditions - mostly highway and motorway commuting.
I’ve been running about 45 PSI until recently when my FE started dropping.
I realized I’ve been checking pressure on weekend afternoons when the weather’s mild (for winter time), but I’m driving late at night and early morning when temps are 10+ degrees less.
Now I’m running about 50 PSI and FE has stabilized again.
