Looking into the pros and cons of increasing your tyre pressures for lower rolling resistance and better mpg and I have confirmed that here in the UK it is illegal to operate your vehicle on the highway with tyre pressures above or below the manufacturers recommended figures for your vehicle.
What I am doing though, is I have dug out a second inflator pump to keep in the garage, one that I don't have to coil up and tuck away the cable (as I do the one in the boot/trunk), so that I am much more likely to check and adjust my tyre pressures every couple of days.
