I love the Bonti set up and the tyres as well(Not the juice, though).
Are you sure the tyres are tubeless ready? Trek (and others) sometimes fit shit OEM tyres that look the part but are made of plastic.
I can't understand this as I am sure it puts people off buying their brand of tyres period. First impressions and all that.
Should pump up easy with a track pump especially if they have been on the rim before so have a good "shape".
You can use the rimstrips and valves on other rims too as long as they are wide enough(WTB Lazerdisc Trails).
Also I have had a couple of real tight tyres – I bust the bead in one.
