I purchased a set of tyres and rims a long while back, they sold me insurance on the tyres too.
Unfortunately one tyre was damaged and not repairable, went back to claim for insurance. They replaced the tyre, but the problem was when they measured my damaged tyre, thread remaining was 5mm, but that was measured towards the flanks of the tyre, so I asked they measure the new tyre, they measured on the center, I then asked why not measure my tyre on the center too, consultant refused saying thats how they do things, I insisted and they measured it to be 8mm, so i said that therefore I do not have to pay anything since it is still 8mm as a new tyre, guy refused.
I then asked he measures the new tyre on the flank too same way he did with damaged tyre, he refused, as I was pressed with time i paid and left, went to another tyre fitment center, they tested the new tyre and it measured 6mm on the outer parts of the tyre.
I sent the proof to their insurance admin, they promised to sort this out, later they told me there is nothing they can do, called TWT head office, a guy by the name of Chris called saying he would call me back later, that was last year around June.
