Are My Michelin Tires Dry-Rotting?

OK, I just got back from the dealer who (of course) passed me along to Michelin's customer service and after finding someone who I could understand (why these companies us foreign speaking agents just eludes me)was told that they accept that the tires are defective, they call it "ozone damage" to which I called B.S. pointing out that the several other cars around me with various different makes of tires weren't "ozone damaged" including the bloody tires on my golf cart!! They claimed under-inflation(I have the Tire-Minder System that monitors my tire pressures constantly), lack of use(she's our daily driver), Canadian winter(baby's NEVER SEEN a Canadian winter), long and short is they will cover 50% of the cost of the tire and I'm out around a $1000.00! their explanation is that according to tread depth I used up 50% of the tire(so apparently their saying these LT235-80R17 tires only last some 60.000KLM's since there are less than 30.000KLM's on them now and their half used!!) again,,B.S.

I'm going to have a cold beer and grill up some ribs and consider my next move!
