Inner tubes for 700x40c tyres

[Firmo]

For those of you that use cyclocross and similar bikes, what inner tubes do you use?

I'm running a pair of WTB Nano 700 x 40c tyres and the normal 700 x 18-25c tubes are just not enough.

lots of 700 x 32/38 availability which are suitable

Specialized do some 32-50mm IIRC

Pretty sure that is what I have incase tubeless fails. Incidentally, Nano's were super easy to get set up tubeless

Nutrak do a 700 x 35/45 tube. I bought some yesterday for my cda. Was going to go tubeless but the tyres aren't tubeless and too loose on the rim. I'll go tubeless eventually when the tyres need swapping.
