I have recently gone over from BB's to Avons as well.

My BB's had less than 500 miles on them and after the car sat for several months in the garage they started cracking and splitting, then one by one just blew out (literally) from the sidewalls.

I also spoke to a Goodyear Racing rep who told me that the compound in these tires have no preservative or plastisizers. He said they are made to buy on Friday, race all weekend and toss them on Monday. I asked why they don't make the BB's in a modern radial like Avons and he said the demand was not big enough for that investment.
