In what way is offering to check someone's tire pressure and then inflate it for a nominal fee, or a donation, "dishonest"? The first scenario is one a lot of Jiffy Lube-type garages and auto parts stores like Pep Boys do all the time (although typically with more than just tire pressure, e.g. transmission fluid). The latter -- asking for donations and letting people pay what they want -- is something the Boy Scouts in my hometown used to do all the time. Free air for your tires, free coffee by the side of the Interstate ... I saw them doing free brake light replacement once. In theory they'd do it for free if someone really couldn't afford it, but in practice people pay what they think the service is worth (or whatever of that they happen to have on hand), so it's a sort of self-defined "sliding scale." I don't see any misrepresentation there so I don't see how it's inherently dishonest.
