Got new tyres for the commuter. Ones fine the other has two bulges one either side but not in the same place.
43mm most of the way round then 47mm at the bulge. Got 65psi in it says 50-70 on the tyre.They’re Schwalbe Marathon with snake skin is it a problem? Thanks.

Wrong size inner tube?

Well yer it’s a bit big. Says 1.75 – 2.35 it’s a Bontrager and looks bigger then the one that went in the other tyre.
Didn’t think it was much of a issue but if that’s a possible cause I’ll get something else. Cheers.
