I was riding in my C5 today, and did a turn in the road. It's a huge road, so it allowed for the massive area needed to acheive a full turn without reversing (luckily).
When I turned, I was travelling with power on, and I heard the rear tyres 'dragging'. It was as if they were flat, but I can assure you they're certainly not flat. Could it be that the way the C5 turns could cause the tyres to pull sideways on the tarmac, causing this sound? I wouldn't want to find that the tyre gets 'ripped' from the wheel when I turn.
When I take my C5 to work tomorrow, I plan to visit the local cycle shop. They've asked to see it for old time sake. I've asked them to look it over, as I haven't a clue what kind of tyres my seller has fitted, and also my wing mirrors have both fallen off, and I think the clips which hold them on have both broken! It'll give them something to do. It's too fiddly for me. I haven't the patience. If I were to try and fix them, I'd lose my temper with them and they'd be in the bin by now!
