Going to throw this one out there to get some info/real world examples as plenty of you US based people get the chance to do serious rock crawlling.
I was taking my D3 (LR3 to others ) around some lanes on Monday and Tuesday with Defender driving mates. One lane we did is very rocky and even though i've driven it before without incident with the same tyres.
This time i suffered a blow out half way up the lane. It was a front left tyre that let go. The inner sidewall blew out with a hole large enough to put a thumb into.
Tyres are Goodyear Duratrac's in 19 inch size.
I had the pressures set at 38psi all round. I've ran that pressure before and had no issues, i've used the car in every terrain bar sand at that pressure and have not suffered because of it.
Now. The lane does have sharp rock areas along it's length and the area i was on when it let go didn't have any sharp bit's that the group could see to be the main reason for the failure so could have been damaged earlier and driven on till it failed.
I've been told that i should have lowered my pressures to 15psi max and driven over the rocks in that way.
I'll be very honest and say, i have only been doing this off road driving for 2 years and i've only been driving for 10 years, i'm 27 and passed at 17 which is when you can learn in the UK. So i'm not sure if that info is correct or wrong.
No one in the Defender's lowered their pressures or suffered failures. My car was being used as the supply/back up truck and was loaded accordingly and had 4 people in it.
What would you have done?
I can get pictures of the lane in question if that would help give more info/answers.
