It's pretty clear to me this is a design or manufacturing fault since the tyres are being used at their factory inflation level and have never gone over their max weight.
Looking at the location it appears as if the material there is being pinched during use. It's possible that the area around the valve is reinforced and this transfers stress to the nearest unreinforced portion of the tyre thus pinching it and causing it to weaken due to repetitive pinch/release cycles. At least that's my guess.
What pressure is in the tyres? Have you checked them.

I had one replaced by Hobie a few years back, same problem exactly.
On the other hand you have to be really careful not to over inflate them as they are easy to blow up.

Factory pressure. I can't check them as the only gauges I have are intended for cars and cannot reliably read anything under about 10psi.

I found my wheels to be under pressure (1lb) from the dealer, I run them at the max 4lb under inflation can be worse than over inflation as the side wall flex's more.

Followup: Hobie agreed to replace both tyres ... so a good resolution as far as I'm concerned. I'm not using them anymore as I'm launching from a spot where there's not much sand but will keep them set aside for times when I really need them .
