Tyre repair Bolton - recommendations please

[RRH]

Chaps (and ladies, obvs)

One of the staff at our Bolton factory (social enterprise) has a slow puncture.

Last time he went to a tyre place with a puncture, we got a bill for a totally unnecessary replacement tyre.

Can anyone recommend a sensible independent (that you have experience of) who won’t rip him off please?

Thanks muchly.
