Welcome as a 'Guest' member anyway, David . If you haven't got the questionaire you need to become a full member, send a message asking for one with your email address for reply, to Tim as a private message, or as an email to mods.twosixties@gmail.com
As far as the owner's handbook is concerned, these MAY still be available on the 'Bay: https://www.ebay.co.uk/itm/MG-ZT-ZT-...sAAOSwJkJWjmMq . Reasonable price, I think.
Tyres are 34 lb/ft front, 36 rear (2.3, 2.4 bar resp.).
May I ask what the VIN of your car is, please? Last 3 digits enough. Maybe we know the car here?
David
