Mk2 inner tube and tyre conversion

[wonkywheel]

Hi,
Need a bit of advise for a Mk2 inner tube for the front wheel.
Can't find a 80/100/16 tube.
This is what I have found:
250/275/16
275/300/16
Would either be ok?
I'll probably be fitting the standard 80/100/16 tyre- so i recon the 250/273/16 would be the best option.
Saying that- what tyres are you fitting to the front, as the standard tyre is hard to find?

225 250 16 is what your looking for . so id go with the smaller of what you can get as its the closest . or I have the 225 if you need one .
