I just put a pair of 2.2 UST Conti rubber queens on my XT rims.
They inflate fine with a track pump but soon go flat despite being seated.
The air is leaking through pinhole leaks in the sidewalls.
I didn´t have much sealant to hand so it´s not really helping, will they be ok if I chuck in a bottle or so tomorrow?
Is it normal for these tires to leak like that?
My HR´s were fine on the same rims and held pressure (with sealant).
