I drove the van down to the tyre shop for them to have a look at the tire and put it right. Well that didn't work, they found a leak all right but in the wheel and not the tyre, so I had to go and find a new wheel.
I spent a day on the net looking for a wheel but they were all too expensive. So next day I phoned round the local scrap yards and got one local at a reasonable price.
I picked up the wheel and went back to the tyre shop, where they changed over the tyer on to the new wheel free of charge.
So a hole in a wheel coast me close to £100, a hole in a wheel, something I have never heard of before and I hope will never again.
