@Josiah, hehehe..! that is correct, the default sizes and pressure in on a tag sticker. :-)
IMHO, The problems start when :
a) Changing RIM size b) Changing Tyre Profile Size c) Smooth Ride versus Economy d) Economy versus safety e) Safety versus performance
IMHO, should not be a problem, if you follow the info on the door sticker or the owner's manual.
And pressure seems to be a crazy topic. How detailed do we get to achieve the correct pressure. Asking local tyre experts, opp tyre importers, has not helped much before. Also, petrol stations tend to give different PSI readings with their pressure facilities which makes it more difficult to know.
Now that's true. Recently I checked my pressure at one station, which had the old-fangled dial type gauge. Wasn't satisfied, so went to another place where they had the digital gauge. That one showed me I'd over-inflated each tyre by 14 PSI, and I corrected that. Just up the road, decided to triple-check with another digital pump, and now that one showed under-inflation.... I think Weights and Measures dept. should randomly check if these gadgets are correctly calibrated, since it's got a direct bearing on safety and economy. BR, S -- Sent from my socks®
