I posted to this thread last year and will take this opportunity to follow up.
I went with stock-size 27" Interco Sniper 920's for my 2021 P1K5 LE.
I don't have enough miles, terrain or winter seasons on the tires to say much other than they seem to be pretty good tires. My rig is street legal and I ride pavement and gravel roads a lot, and at high speeds. I also need to plow snow that gets super deep with an ice rink underneath. I am happy with the tires so far, but this will be my first winter. (It's coming . . , sorry cliche).
My
huge gripe and dumb sh_t regret is that I didn't go with 28's. This tire comes in 28" 11-14 and 9-14 and I should have done it. I'd like a little more clearance and the posts state that 28" tires don't need modifications---not that there's anything wrong with modifications. [I can't modify or lift much because I'm an inch clear under a garage door that would take load-bearing structural work to change.]
The photos are of my rig with the 27" 920's and my newest purchase: v-bar chains. I'm at 8,000 feet in Utah's Wasatch Mountains - tons of snow and ice. I'm now scrounging for carpet remnants so those v-bars don't cleat the cement in the garage. The chain tensioners showed up today.
Good luck.
