So 50 sets of car tyres in 15 years, so you go through over 3 sets a year then? And out of those 50, how many have been on a EP3?
Wheels bend up in potholes? WTF is that supposed to mean? and Running higher pressure's decreases traction, so your theory about traction and wheel spin 'leaving you behind' is absolute rubbish.
And, going by your statement of carrying a buggie and a baby bag therefore I can only conclude you carry a baby at times, so why would you even care about being 'left behind'
The Bridgestone is such a stiff walled tyre that 32/30 for normal use is absolutely fine if you're running fully loaded then yes increase it, but how often are you actually fully loaded.
And why ask a question, when you've already decided the answer so anyone elses opinion get's shot down by your irrational logic and sketchy posts.
Peace
