you can now get to kwik fit in hexham without the need for a james bond style submersible car. you could try them or give SEM a call. they refurbish wheels in sunderland but I think they fit tyres to. and they always do a good job.
How very strange as every time I've asked if they have a part they look blank and ask what it is. Stupid things like fuel pipe, heat blankets, Fuel pumps, door mirrors... useless company IMO.
