Hi again - some useful information has come through from Toyota UK - they sent out a general e-mail to all Toyota groups and have had, sadly and surprisingly?, only a limited response - three Toyota Centres have replied to confirm that they have the equipment necessary to deal with SR180 run flats - Sheffield, Colchester and Leicester - it would appear that there is not that much call for it these days, most owners of 'ancient' RAV4s it would appear have opted to replace the run flats with standard tyres - I'll be heading to Sheffield in the not too distant future! - many thanks for you
