Tyre & Tube question

[rusky]

I have a 29er hybrid & have a pair of Continental Vapor tyres which are 54-622.

The tubes I have are also Continental & are 700 32-47.

Question: is it OK/advisable to use said tubes with said tyres since the tyres are 7mm bigger than the tubes?

I have checked t'interweb & can't see any 700 tubes that go bigger than 47.

Shouldn't be a problem. Tubes have to get very much bigger before they go bang.

But it's a great way of getting the neighbourhood worried about gun crime if you do ever to manage to burst an inner tube.....
