Don't know if this is the case with wider tires, but one issue with some road tubeless tires is that they don't play nice with tubes. This spring I had a puncture that would not seal due to me being remiss in not adding fresh sealant. I had to limp back to the car because I could not get the tire (25c) to seat properly with a tube in it. Despite trying three times, it kept bulging at the valve stem hole. I would at least test fit a tube in your tire before embarking.
