In my opinion and the opinion of a couple of tyre fitters I do a bit of business with, alot of the chipping and wear issues are to do with tyre width in relation to how it's driven but in saying that, my Jeep used to take chunks out of S/T's on sandy gravel roads.
I know the wider tyres provide more stability and look a crap load better and I dont know the reason behind it but most of the people with chipping problems are running wide tyres and generally drive harder because they can on dirt roads.
I run 235 85 16's BFG AT's on my D1 and I dont find them unstable at all though I generally get a bit left behind by the big tyre crews until the slower stuff evens the score and then they dig much better and dont slde around as much as the bigger boys.
I know there are going to be people probably going to not like my comments but Im not saying you chouldnt have wider tyres, I have just noticed in 10 years of working in a tyre joint and what my suppliers have agreed with me about the wider tyres.
It's your choice in the end but I would stay well clear of coopers, too many horror stories and there's a constant there was a bad batch story but it seems that that bad batch was every thing up to when I need tyres.
Do a search for tyres and spend the next week reading about all the horror stories about all of them, I went back to BFG AT's as the last set got me 130000kms and I go 4wding about every second weekend when we can and only ever got 1 puncture in that set but there are people who havnt had a good run with them so make your own mind up.
