- A90 tyres and tubes
-
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.
5.50x16 X-Stop
Marke: Michelin Dimension: 5.50R16 H(84) (175/80R16) Tubetype/
Tubeless:Tubetype Tragfähigkeit: 500 kg 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.
