Hi all thanks for the forum, me and my wife have just entered into cycling for the first time and have 2 Cube Acid Hybrid ONE 400 29 black´n´green E Bikes.
I am thinking of fitting some puncture resistant inner tubes or airless tires if possible, the tires have the following marking son the tires

I can only seem to find treated inner tubes like Slime that go to from 29/ 1.85 - 2.20.

The main question is, does the inner tube have to be the exact same size as the tire or would this be OK also are there any airless tires out there this size I cant seem to find any. Thanks in advance.

Really no response to this please I would like to order for 4 wheels so not cheap and want to be certain that 29/1.85-2.20 will be OK or should I match the tire size to 29/2.25 if possible.
Please I can only order online and really would like to know the answer asap.
