    Been over inflating tires by 4 pounds for many years. 😁

    Been overinflating my tires by much more than 4 PSI for decades. I've never had a problem with unusual tread wear, though that may be in part due to the fact my cars' tires tend to be relatively narrow width. (Never had a car with wider than 185's.)

    claims that he can get an extra 3-5 litres per 100 km
    I don't think it's going to be that big an effect. Mythbusters ran a test (admittedly not the most scientific) and found:

    Control, 35psi (manufacturer recomendation)
    tyres at 10psi = 3.7% increase in consumption
    tyres at 30psi = 1.2% increase in consumption
    tyres at 40psi = 6.2% decrease in consumption
    tyres at 60psi = 7.6% decrease in consumption
