They are 195/60/R15s 88V (Avon, not Continental as I previously stated). 22psi all round as per spec in the manual.
Thanks for the advice on trying LLOYDS in Hexham and the pros and cons of varying the tyre specs. It is troublesome with regards to ground clearance round here so I’d value a slightly higher ride. I’ll let you know how I get on! Maybe I shouldn’t have grumbled quite so much about continuously deteriorating road surfaces over the last 10-15 years
