Tire size for 650Bx47 WTB Byways

I am not sure what tire size to select for 650Bx47 tires. I am trying to get setup with wahoo speed and cadence sensors on a fluid2 trainer. Can someone help please?

I have some of those tires - what choices do you have?

650c several 700c’s but nothing that seems to equate to 650Bx47. Wondering if there is a close enough choice out there.

If you have 700-30c then that’s about spot on. Anything in the 700-28c to 700-32c range will be fine too.
