Hi - Have been looking for tyres suitable for classic sidecar racing, currently run 16"-3 front and 15"-3.5 rear rims. Tyres are Bridgestone BT45 120/70/16 front and Maxxis 130/90/15 rear. What i am chasing is a more suitable front tyre especially as front pushes in corners even with 18psi in it - works ok but looking for improvement. The old Dunlop sidecar racing tyre is what i am after, does anyone know where or if they can still be found and what size they where. Bike is '61 A10 sidey.
