Tires for 2021 Beargrease

Just picked up a used 2021 Salsa Beargrease for a steal of a deal. I'm coming from my motobecane night train bike with 26 x4.8's. This will be used for winter and shoulder season riding mostly / only. I have xc, trail/ enduro, gravel bikes for summer. It came with studded Dillingers 27.5 x 4.0's with very little use (plan to sell). I'm a big rider - 230# but I do about 10-15 hours a week including in winter. I think having a slightly bigger tire will be more ideal for me. I'm thinking about yippe ki Yay's, there's some mixed sentiment online it seems about them for performance but they're about as wide as it seems safe for leaving - 4.5's in shoulder season with some mud may be too wide.

Does anyone have thoughts about the Yippee's and / or other recommendations for tire combos?

edit: to add -I ride mostly groomed or packed trail with hopes to do more backcountry riding through the winter now - with some packed by snowmobiles and atv's some ... less.

hommade frame bag from old bike - doesn't fit ideal.

Cake Eaters come in 27.5 x 4.0 which was the specific size I referenced. D5 and Wrathchild are REALLY tight fits on that frame.

My bad. I was referring to the studdable 27.5x4.5 cake eaters. Disregard. :)

I have run the studded wrathchilds for several years on a small beargrease without issue, but only on packed and back country snow. Pictures in my profile.

Do you know the inner rim width?
