Dick Cepek FCII Tyre Failure?

I bought 8 of these when I first bought the LC100 in may 2004 (For camper trailer) I thought they were great (and still do ... sort of) - Originally I intended to rotate all 8 to maximise and evnely distribute wear. But I got lazy and only did it once at about 10,000k - I knocked 1 lug off during our 04 desert trip and consequently convenced them to replace it under warranty (Cost $60 after prorata wear and tear) - So these 5 tyres have been on since and the vehicle has done over 90,000k so I was pretty happy with them.

Late last year I did a couple trips up the bush and dropped my tyre pressures lower than usual down to just under 20psi. After the last trip I noticed at least 2 lugs gone on each of the tyres and cracks appearing between the main tread and the body of the tyre. Having traded the LC100 and waiting for a new 200 I wasn't about to put new tyres on it so I kept an eye on them.

Going up the hume a week or so back at 110kph I lost a tyre all together completely delaminated and basically shreaded it. BTW it handled beautifully giving ample time slow down safely and pull over.

So not wishing to push it any further with I pulled into the nearest tyre joint and a bought 5 good condition second hand tyres. (2 Coppers, 2 Bridgestones and a Japanese thingy as a spare)

I still reckon the tyres have served me very well at least 2 or 3 of them have done over 90,000ks so I don't feel ripped off except they had a good 10-15,000ks of tread left on them and then this.

So not sure what I'll put on the 200 yet but thought some might find this interesting.

PS: Tyres were 285/75/R16s so after a 5% correction the actual ground covered is closer to 100,000k
