VW Polo Wheel and Tyre (Bourne End SL8)

This was removed from my 2010 VW Polo.

I got a flat tyre and this was bought new to replace it. However, it still kept going flat, so I think the wheel itself Is the problem - the garage couldn't find the leak, suspected it might be due to some corrosion. I've since replaced the wheel and the new one came with a tyre.

So, this tyre has had very little use, but it has sat flat for days at a time. It passed a recent MOT.
