Tyre 37-622 - What Inner Tube?

Apologies - newbie question.

I have a tyre with the sizing description 37-622. It has a schrader valve.

According to the Euro sizing chart, this equates to:
700 x 37C
(28 x 1 3/8) or (28 x 1 3/8 x 1 5/8)
(sometimes labelled 700 x 35C)

I take it my wheel size is 700c. Width 37c.

What inner tube size can I buy?
I take it as long as the figure is 37 or above I will be fine?
Would a 28-37 be better than a 32-47?
Any recommendations?

adroit

pretty much any of those tubes will do the job, as they stretch when you pump them up to fit the tyre. Magic stuff, rubber.

Butters

28-37 will be a tiny bit lighter than 32-47, but the inner tube will be stretched more, potentially increasing the chance of puncture (kind of guessing this bit). The difference on both these points is likely to be so small that you can safely ignore. I guess the only choice influencing factor could be if you might run bigger or smaller tyres in the future.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
