Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.
Discussions that report identifying a cause

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Leading evidence: 'tires themselves' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'tires themselves' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Disconnect battery' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
Disconnect the battery for 10-15 minutes to force the PSM's TRAC section to "recalibrate" the wheel sensors.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I just had the rears changed on my '99 c4 (factory spec 18" all around) and the PSM started going off for no apparent reason. First time was on the way home (after they closed so I didn't turn right around) and it's happened a few times since, both on and off the brakes. Pressures and sizes are correct on all four corners. Indy says it could be an ABS sensor in one of the wheels and it's going back tomorrow. Any other theories and is there any chance they could have contributed to this during the tire-changing process, either by banging into something or excess grease/tire shine? It seems a very odd coincidence.
You removed worn tires (well worn..??) and installed NEW tires and of course the circumference of the new tires is greater than those you took off, especially with reference to the remaining "old" front tires. Disconnect the battery for 10-15 minutes to force the PSM's TRAC section to "recalibrate" the wheel sensors.
Good news... Looks like it was the tires themselves. Guys, be careful out there when you put new tires on. They can be slippery as ice for the first few miles (esp in the rain), and apparently need a few (100 or so) miles before they break in.
Yes, new tires have a chemical on them which the manufacturers use in the tire mold as a "mold release." This helps them extract the tires from the mold. The chemical is very slick and takes a few miles for the chemical to wear off.
I guess it is like K-Y jelly for tires!
