Had a good clean of the Bus wheels today and noticed that the tyre wall in the middle of one of the rear tyres is starting to crack and split most of the way round. I am surprised that this wasn't noticed in the MOT. The tyre is a brand called Cheng Shan, not a brand I have ever come across before.
I will have a new tyre fitted tomorrow.
More expense, although you can't feck about for the sake of a few pounds were safety is concerned.
