Is it ok to use a solid rubber tyre for my tail dolly wheel, or do I
risk damaging the glider?

You don't say what the glider is or how your tail dolly works, which
would be useful information.

That said, I think a solid rubber tyre is fine *provided that* the dolly
is off the ground when the glider is being towed by a vehicle, i.e. the
weight of the dolly and rear end of the glider is carried by the tow
ball. The dollies for both gliders I've owned have been lifted off the
ground when the tow bar is attached to a vehicle. With this arrangement
the only time you'll move the glider on the dolly when is when the towbar
is detached and you're moving the glider slowly by hand, so having a
solid tyre is no problem.

The type of dolly that rolls along the ground when being towed by a
vehicle may benefit from having a larger wheel with a pneumatic type
fitted, but I have no experience of using this type.
