Are sheffield bus tickets valid to tinsley?

Just wondered if anyone can confirm if sheffield bus tickets such as sheffield citywide and firstday sheffield tickets are valid to Tinsley?. not sure because rotherham day tickets are valid through to Meadowhall. Some bus drivers seem to think that the motorway is the boundary for sheffield tickets. Tinsley is most definately in Sheffield so i believe sheffield tickets are valid to there.

Magna

Bawtry Road/Ackworth Drive

Tinsley is included.

Use the links from this page, and you will end up with a list:

It is very complex, they are valid to Tinsley from Sheffield as has been stated as far as the magna stop (note big Rotherham sign there) and to Ackworth drive ( note big Rotherham sign there as well) they are also valid to Brinsworth ( in Rotherham) but only via Catcliffe not via Tinsley.

So you can use it from Meadowhall / Sheffield to Tinsley via Meadowhall or Sheffield to Brinsworth via Catcliffe but not Brinsworth to Tinsley. Could they make it any more complex?
