DO you 'need' a turbo trainer tyre?

[Kell]

What's the rationale for having a separate tyre for turbo trainers?

Is it just a wearing out issue, or something else?

It was more a case of I don't have an spare wheels lying around and if I wanted to do an hour or so at night while my daughter's asleep, I don't want to faff about changing tyres to do that and then have to change again to go out at weekends.

Noise and dirt aren't an issue as it would be used in the garage.

Thanks all. I think I'll give it a go as it is for now. The rear tyre's not great anyway.
