Spoke strike on innertube...?

I dunno what the correct term is for this is but after hitting a really deep pothole yesterday I got a flat, but after pulling aside and inspecting the inner tube, I found there were two parallel 5mm slit marks (on the inside, where tube rests with the rim) possibly caused by the spokes?
I got nylon rim tape on both front and rears so im well confused as to how this can happen...anyone help?
Do I need rubber rim tape or something more flexy?

thanks!

prolly a pinch flat not a spoke poke
if you do a spoke, you'll see it puncture through the rim tape and it will be noticeable and loose
you probably just compressed the tyre and squished the inner tube against the rim pinching it and causing a puncture

Pinch flat also known as a "snakebite" flat for that very reason - two holes, side by side like a snake bite.

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.
