Carlsson into an off road car.
The kit contained 8 foam tires, 4 tracks, replacement rear suspension arms and chaindrive.
The instruction showed how you should glue the foames on your existing rims
and then glue the tracks to make a rings wich then should be glued on the outside of the foames.

The result should have looked as this picture.

But most likely the end result looked like this.

Glue everywhere and the track is not fixed properly to the foames.
At least the screws should give you traction.
Carlsson abandoned the concept after a while and made regular off road tires for later kits.

But all off road Carlssons were based on on road chassis.
This is the last model i know of.
