275/65/20 winter tires on 2023 Tahoe high country

[olyelr]

Olyelr, if one goes with toyo MT's in that size, its exactly 34.5 in diameter and 11" wide. This is 1.07" taller than the stock tire. I removed the metal bracket behind the front tires and trimmed a bit in the back and measured about 1.25" before the stock tire would hit the metal framing at full crank. With 1.25" of space before hitting and given that the Toyo MT's are 1.07" taller than stock, there is about 0.18" of space before a toyo MT at 34.5" x 11" wide would hit. At stock height with no lift...this is cutting it very close but does this sound dangerous to drive on road?

I wouldnt say dangerous. But its possible you may have to do a bit more clearancing.
