Tubes for Schwalbe Marathons

My Catrike Trail has Schwalbe Marathons (20x1.5) and I am constantly getting flats. Not while riding, but I'll go out to the garage and a fresh tube will be flat.

I am inflating to the specified pressure (even less sometimes because I thought that was the issue) and am still having issues. I ride on clean surfaces and I have found no punctures in the tires. I'm wondering if the tubes I'm using are too big. I've tried 4-5 different brands, the most recent being Sunlite and Specialized.

I've probably gone through 10-15 tubes in the last year, and that's with minimal riding (I've been out of town at school). What are other people using with these tires?

How are the inner surfaces of your rims?
How are your rim strips?
Is the hole in the tube always in the same place?
How is your installation technique?
Haven't found anything sticking through on the inside of the tire?

Marathons are not known to be delicate tires.

You want a 20x1.5-1.75 tube but should probably be thinking about the questions above and maybe these extras. Are the flats always or almost always associated with the same wheel and tire? Have you very very carefully examined the tire or tire? By feel? Under excellent light? Small pieces of metal wire can hide well. Do you live in goat head torn territory?

If these questions don't lead to an answer you might take some time to view this installation video. When ever I think Schwalbe Marathon I wince at the thought of mounting them without ruining the tube. The video helped me, perhaps you'll find it not only entertaining but also helpful.

I'll go a different direction.....

I have found it necessary to add air every 2 to 3 to 7 days which I've always found to be necessary on any bike tire to maintain proper inflation. Heck, even on a car you have to add air in normal usage without a leak. You say you don't ride very often.... and that you have found no punctures. It may be just common pressure loss the rest of us check every day or two - and top the tire off.

I'm out on tour now and I check my tires daily and add air every 2-3 days.

Thanks for all the info. I just took two pictures with a Sunlite 20x1-3/8 tube in the tire (slightly inflated).

Here are the pics (2): https://imgur.com/a/T2pbv

See how much slack there is? What do you make of this picture? This isn't normal right?

Ah, light dawns. You want to get some tubes marked in decimal sizes, 20x1.5-1.75. With tubes, 1.5 is not the same as 1 1/2. As is often the case, the late great Sheldon Brown explains the strangeness well.

I've folded tubes like that and it works for a while. For instance, in one case it too a year before it wore through at the fold and caused a flat. It's definitely the wrong size tube, but there's something else going on if it flats all the time. Or, if it gradually goes flat over the course of a couple weeks or months, then it's just normal leakage.

I hear Marathon Plus tyres are notoriously hard to fit.

The first time I ever removed a tyre in my life I took off a worn out Marathon Plus (that the bike shop fitted) and fitted a Marathon Extreme to replace it. Yes it was fiddly but having never done anything quite like it in my life I wasn't exactly an expert.


Add another vote for slow leakage which is normal. Something else I learned when I was new to cycling when my 70psi tyres seemed soft and had dropped to more like 30psi, over the course of a few weeks.

That picture is a Marathon, not the Plus version. The non-plus tires are not hard to fit.

Tubes do slowly lose air, but thicker ones (like the expensive ones Schwalbe sells) lose it slower. My recumbent has Schwalbe tubes, and I only need to inflate the tires about once a month.
