I bought a BMW F800 Adventure with Mitas front and back tyre already fitted. The bike has done about 500km with the tyres.
We went to the Hell & Baviaanskloof for a long weekend. I had the first flat tyre at Mooreesburg. We stop at a tyre fitment centre where the guys pulled the tyre of the rim and saw that it had a tear in the side wall of about 50MM.
Having no other choice they repaired the tyre with a patch on the inside and also the tube. We then left for Sutherland via the Tankwa Karoo stall which burnt down the next day.
Long story short the tyre started losing pressure again at Willowmore. (Rony AKA Malletjie) from Jumpers helped us out on Sunday with a secondhand tyre (Not Mitas) and a brand new tube. I was very greatfull! Everybody can definetely pop in there. We had cold beers afterwards and was on our way. Thanks again to him. To get back to the topic. The Mitas rear tyre had 2 extra tears in the side wall on totally different places. We left the tyre with him.
I have got no idea why this would happen?
Side wall failure
Generally Mitas E07 and E09's are known for strong sidewalls in my experience. Inevitably you will have hit sharp rocks hard … possibly with tyres that could have been over inflated for the conditions … Tankwa has some of the most abrasive rocks around 
Just for interest I watched the fitter here in Centurion fit my new E09 tyre yesterday. He tore my bead badly but no problem just coated it with more soapy stuff
and fitted the tyre just like that. I went to the manager and he had him take it off again. Promised me a new tyre (which apparently will be here today ),fitted my old tyre again and now I am nervously waiting,hoping,wondering if my nat. bash trip is now sunk.
So check while they are fitting your tyres so no damage is done at the fitting machine already.
