Update
At the end of September the P6 was transferred from the old Garage to a new one. Unfortunately, the new is more than 50 km far away from my home address. But for the winter season the problem is solved and everything is ok. It was necessary to do this using a trailer because the ignition lock didn't work. In the next weeks I will try to repair it. Also, I want to reassemble the parts below the dashboard which I had removed to change the choke-wire.
In March 2014 I will mount the rostyles which I have bought. As I have heard here in Austria from the former president of the Rover Club Austria, Rostyles are never around, a car with this wheels will always vibrate. But I think I have learned from my old Mini a lot of years ago, how I have to mount wheels correctly. It was important to mount the nuts one after the other and to shake the wheel so that all cone do fit properly. Otherwise, the car has vibrates even though the wheels were balanced. Hopefully this method will work also in case of Rostyles?!
Or what are you thinking is important that Rostyles generate no problems?
And finally: what tyres would you prefer in conjunction with Rostyles?
