Very amateur PR by Outwell, with the 'stay around the pitch all day' business. Not good.
As for the pressure, I think I saw a theory on this forum a while back suggesting that temperature rises are not likely to be enough to cause enough of a pressure increase to blow the tubes. I'd agree. By my school-boy physics, (rusty these days, I'll admit) a temperature rise from say 20 degrees to 40 degrees is only an increase of less than 7% (measuring from absolute zero of course...). So, if you've inflated to 0.7 bar at 20 degrees and the temp rises to 40 degrees, then the pressure would still be less than 0.75 bar, which is within the recommended limits. Feel free to shoot me down, I'm no professor.
However, if the reinforcing sleeve, which gives the inflated tube its strength, splits, either through disintegration, or because the seam glue gives up because it's hot, (not necessarily because the force of the pressure within is too high), then yes, you're in the 5h1t.
