Rear tyre by Hola Siesta, on Flickr

This is my back tyre. Schwalbe Marathon Mondial. Amazing tyres and this one still has lots of tread on it.

But as you can see, there are angled wear lines equally spaced all around the tyre. Which then started to split.

Am I just too powerful and applying too much torque? I used to track race as a kid.
Riding with too lower pressure?
Defect?
It is not the load. I am big but riding light. And these are the best tyres for loaded touring.

Any ideas?

stress tears?
Looks like the tyre is ripping to me in the same "band"
Too low pressure means tyre goes soft and twists/stresses as it is at the contact point and can Fold?

Never seen anything like that and guessing tbh at the causes.

Looks to me like too low pressures John

I usually get crossing threads under wear with little pressure (fatbike and plus bike).
Is it possible that this tyre hasn't got crossed threads?

a bit to little pressure, and that is what happens when cornering.
I used to get it quite a lot on mtb tyres with narrow rims. the tyre is put under massive force when cornering.

and from looking at your bike set, you must be pretty big, like me, so there are massive massive massive forces going through the tyre when cornering.

Low pressure with wider tyres on narrower rims and my lump sat on top has got those checkered patterns for me, but not tears like that. Took a while though.

Thanks for the replies.
I've ordered another one as there isn't anything much better for desert thorns.
I am pretty sure that the pressure is high enough but I do feel it roll a bit when cornering tightly.
