Sorry but I also cannot agree that it is "just" a tyre problem.
If the OP had gone through one or two sets of tyres, then yes, probably due to cheap Chinese jobs with a questionable quality & lifespan. But FIVE sets in as many months??
I would like to see the wear patterns of the worn tyres - that would (should) give some indication to the problem. But I don't think any 1997 Boxster is going to handle very well with 19" wheels on anyway, especially if the larger wheels have caused wheel bearing or structural damage to the rear end as per what Jeff (JFP in PA) says.
If there is any weld or componant breakage to the rear structure, the rear end will move around like a dogs tail. Anyone having ridden a motorcycle with worn out swingarm bearings will know what I mean - feels OK in a straight line, but when you change directions its as loose as a drunken sailor, causing extreme tyre wear......
