What size tubes for 27.5/650 x 40 tyre?

Hi,
I am new to 650 wheeled bikes and wider tyres. I have just bought a pair of Shwalbe 27.5 x 40 tyres and am wondering what are the best size tubes for them. Would the 1.5 to 2.4 be ok or would they be to big?
Cheers.

Hi,
I presume that the 40 you refer to is 40mm width, which is just over 1,5 inch - so the 1.5-2.4 tubes should be okay.
Vittoria do a 27.5 1.5 - 2.0 tube and Decathlon do a 650b 28-42mm tube if you wanted something a bit narrower.
