May be I can add my experience. I am not an attorney, but I've appeared in several small claims courts as an expert witness for the defense. So I may say some things that aren't technically correct, but that's only because I'm not schooled in "The Law".
The basic principles are:
1) There has to be a "loss".
2) The burden of proof is on the plaintiff
3) The evidence has to be weighted in favor of the plaintiff.
4) The remedy is "to make them whole".
"Loss" - Well, corrosion by itself is not enough. The corrosion has to be a "problem". If the problem is "appearance", then this isn't a very costly "loss". If the problem is "rim wouldn't hold air", then that's a bit more costly, but it could be argued that this is a common problem with alloy rims and that it is inevitable. That the corrosion is part of the "normal wear and tear".
"Burden of proof" - the time element has been extensively discussed. But the plaintiff has to say HOW the tire shop damaged the rims - and unless the plaintiff watched the procedure, there is going to be a disconnect there.
If the plaintiff was there, then he should have pointed out the damage at the time. If the plaintiff wasn't there, then it is conjecture that the rims were damaged at the time of mounting the tires.
"Make him whole" - In other words, put the plaintiff back in exactly in same position before the incident. In this case, that would mean "rims without corrosion with some usage on them." This does not mean "NEW". Since the current rims are "serviceable", this reduces the monetary value of the "loss" to a great extent.
If I were the shop owner I would argue:
- That alloy wheels are prone to corrosion, That it is only a matter of time before it appears.
- That the mounting machine doesn't touch the rim where it was damaged. Only the tire does, and the tire is ALWAYS going to touch the rim during the mouting process - there is no other way.
- That the problem occurred in the subsequent use of the rim and that would explain the time lag.
- That the monetary loss is pretty low. New rims cost (say) $600, that used rims (even in almost perfect condition) would sell for $200, and damaged by serviceable rims can be purchased for $100. That would make the "loss" a total of $200.
- That the problem is only "appearance" and to fix that only takes an hour of buffing and clear coating to return the appearance to its "Before" state - may be $100.
My experience is that Judges bend over backwards for the "Average Joe" (I'm sure there's a Joe the Plumber joke in there somewhere!). Judges will allow all kinds of evidence and testimony in a small claims court where there aren't attorney's present (I don't know what the requirements are in Pennsylvania, but most states ban attorney's from small claims courts.)
So, AJ, make sure you have a receipt showing the transaction and it's date. Try to find a way to explain the connection between the damage and the tire mounting machine. Bring an estimate for a new rim so the Judge has a cost basis from which to work. (Small claims court judges don't want complexity - they want money to exchange hands.)
And lastly, be prepared to walk out of court with very little, if anything, to show for your efforts.
