Hakka 1's sidewall problems

I had a set of Hakka 10s which developed a cracked sidwall roughly
2" from the bead on my 4kq; it looked as though the tires had
been run flat(they had not), and the sidewall rubber cracked.

3 of the 4 did it, all on the inside of the tires.  They were near
the end of their useful life anyway, and none blew out, but
they did do some odd sidewall-related things.

I have studded H10s on my 5kcsq now, all is well - but I will
check the inside sidewalls more frequently - the day I noticed
the sidewall cracks on the 4k, I'd spent a fair bit of time
prerunning/setting up a Solo Trials course (big, fast
autocross - not quite Solo1, as the course was laid out
with cones, but still fast - in setting up features,
I'd been mid-to-high 4th gear in the 4k).  Yeah, got me
a little nervous and a LOT thankful they did not let go
in the middle of a corner.

Iain(ymmv, I still love them, but I thought mine were a fluke)
