I bought now (March 2010) new tyres from Munich (www.oldtimer-reifen.de).
There is a Radial tyre made by Michelin. I choose the radial type instead of the diagonal type for security and comfort, the price was nearly the same as for the diagonal type.
|Dimension:||5.50R16 H(84) (175/80R16)|
|Zul. Höchstgeschw.:||210 km/h|
|Max. Breite:||175 mm|
|Max. Höhe:||685 mm|
The correct tube for the A90 Atlantic convertible rim is the TR-15 one.
The TR-13 also fits, because its smaller, but to avoid movement of the tube, the TR-15 should be taken.
|Recommended Tyre Pressure:|

|Atlantic||26 lbs./inch² 1,79 bar||26 lbs./inch² 1,79 bar||26 lbs./inch² 1,79 bar||28 lbs./inch² 1,93 bar|
