Is this tire pressure increase telling something?
Warm summer sunday drive, I control my tires before doing my usual 30 miles sunday morning drive and they are 36 front 38 rear - what I usually use for street driving - but this time I check again tires after the run (mostly highway running with some 100 miles/hour sprints) and they are 38 front 42 rear!!! I wasn´t expecting such an increase in the rear, specially since last 5 miles were cooling down miles
Is this pressure increase normal in highway driving o should I be using more pressure in the rear?

That appears pretty normal increase.
The rule-of-thumb is about 1 PSI increase per 10 degees of temp increase (air temp). Should be the same for surface increase. This assumes "dry" air in the tires.
A "5 mile cool down" is not really that much, in the larger scope of things.
