Hi,
Same here, the Tamiya tracks work well on tiled floors but are hopless on stone/concrete/tarmac/carpet etc.
Here is a more off road orientated Tamiya of mine -
Its a rock crawler so slow enough to convert to autonomous operation, its also supports front and rear steering. I image that the turning circle of wheeled vehicles would be a bit frustrating without this front/rear steering capability to tighten the turn radius.
It also supports crab steering so you could sort of 'side step' obstacles - might add another dimension to a project, when to turn and when to crab steer.
