I'd just like to clarify, camber does eat the edges, camber is the angle that the wheel sits relative to the hub, or vertical (dependant on application).
I just had a look at those tyres, not much good for my old dear as she drives all year round and according to black circles aren't much cop in the cold/ near freezing, thanks for your advice though. I'd give bead sealer a go before loctite stuff, I've not looked into that yet- I'd want to know it wouldn't cause any problems to the tyre, e.g. causing it to split as it cures (it may be made specifically for tyres but I'm in a rush and don't have time to check right now! It could be a gasket paste for all I know, lol.)
Is there an online manual anywhere with diagrams etc (Like ETKA for VW), I'm not that familiar with Fords.
Cheers.
