Agree with both replies above.

I towed snowmobile trailers in the Bighorn Mts, and there are steep climbs coming from the east. Even in Winter the road from Buffalo, over powder river pass was good, but around 10K summit.

I also rode motorcycle through the Bighorns, both routes, rode/camped near Cody, road all through Yellowstone. Riding MC much more enjoyable than towing!

Curious why you chose Ten Sleep to overnight? Not much there, should be quiet though.

Did the same route last fall...

US-16 is the better route across the Big Horn Mts (vs US-14) but still a decent climb and drop. That's really the mountainous part of getting from Devils Tower to Fishing Bridge.

At 10 Sleep you are past the worst, the route isn't bad at all (north to Greybull then west to Cody). No reason to go way south to Thermopolis.

As far as tires, assuming there are no other issues (balding, bubbles on the sidewall, etc...), 3yrs is fine. Typically around 6-7yrs is when you start to consider tires having aged out.

The road east of Ten Sleep goes thru a high mountain pass and was very snowy when we went thru west to east last late September. Cody thru the park on 14 was also high altitude and actively snowing hard and being plowed at the time. The hot springs at Thermopolis were a major disappointment, concrete pools inside a building.
So be prepared for weather in the park. Of course I have been in snowstorms there in July. The park is high altitude 9000ft more or less. Cody rolls up the sidewalks at the end of September and all the RV parks close. Be sure to visit Lamar Valley if you want to see critters.
I could not believe the prices at Fishing Bridge now.
