The tire pressures, wheel camber and toe limits are set by Pirelli, but are not part of the tech regs themselves. They're usually addendum or technical notes issues at each race. The reason for this, as far as I believe, is because rule changes require an OK from all of the teams - but technical notes are not covered in the same ways because they may need to change depending on the track.
Compliance is enforced by the Race Director, so if he instructs a team that's outside of the tire limits set my Pirelli to change them, failure to do so amounts to a sporting reg penalty, which may be a drive through, stop and go, a DSQ or forced retirement (the "Meatball flag").

“Not that the rule book counts for much the stewards were quite happy to make it up as they went along when Williams ran two tyre compounds. It wasn't like they even changed it straight away so I am fairy sure that was a breach of the technical regulations and generally thr punishment for that is disqualification. They got off quite lightly with a drive through which I don't think is defined anywhere for a breach of tyre regulations.”
It's covered by the racing regulations. Section 25.2c says;
Quote:
“A set of tyres will be deemed to comprise two front and two rear tyres all of which must
be of the same specification.”
The stewards can then decide which penalty applies by looking into section 16 of the sporting regulations. You can download all of the relevant info from
