Cheers guys. My LBS wil want £12 which I think = $20. They will mark up on the tube and the tyre though. Above posts make me realise i will need both. The tyre did have a couple of bulges and the tube has several punctures. Rim tape seems like a good idea. I did some youtubing last night and the whole process doesn't look as bad as I feared. Worst thing is that Im now on a bus bored while Mr Foldy mopes at home....
