3 It seems more probable that the combined effect of heat, and due to the fact that the [armoured crossed out] tyres were run at low pressure so as to stop sinking in soft sand, coupled with the maximum load that was being carried, should have been responsible for the trouble. We should point out the Dunlops recommended that the tyres could have been deflated to 17 lbs, actually they were never let down to less than 23 lbs, and had they been let down to the recommended figure the bursts would have occurred at an earlier stage. The tyres were run @ 35 lbs for the first part of the run, over hard rocky outcrops surfaces and were | ||
