Some Caravan Genius's out there with interesting theories on caravans popping tyres on one side? really?
I have thousands of hours on vans. So does our friend FS.
The strips here in Tanzania are bad, sharp stones, thorns etc. Also, many landings at Arusha and Kili are with cross-winds from the right. So, maybe, just maybe, the right mains are wearing down faster if the correct technique is used ie right main down first, with wind from the right. The valve may have pinched due to tyre creep. Maybe there are inferior quality tyres out there, but I've also had flat wheels with brand new tyres, no thanks to thorns and sharp rocks.
The van in question had a flat "right" main wheel. Ask FS, he was planking on it. funny guy!
