Will this fit 20 x 1 3/8 tires?

Hello. The specs on the Schwalbe tube box state the tube will fit tires of 20 x 1.10 - 1.50. Your tire is 20 x 1 3/8" converted to decimal = 1.375" so it should fit fine.

What's the width of the valve ?

Well no matter what the width was i bought 2 of them and they last exactly a week each😵💫!?!?! So I bought a third one at my bike shop and they are still on my bike. There is something wrong with these sold here… I DO NOT recommend it AT ALL.

what pressure can they handle, I need to go to 110PSI

I’m pretty sure it should be able to handle 110PSI. However, I would check the PSI range printed on the sidewall of the tire.

So is it 4 tubes total for one purchase?

2 tubes, however they lasted only a week.:((( I had to change it again for the second one and got another flat tired. So I went to my bike shop and noticed that the same tube was in a different box… so I CANNOT recommend this tube…:((((
