I agree, no chains necessary. We're heading up for our 10th summer trip in 2021 and although we've hit occasional snow squalls, we never needed chains. As jsummers72 pointed out, if roads get bad all you need to do is pull over for a day or so and things will be clear. One year we were told that Tok Alaska had 27" of snow 5 days before we arrived and we never even saw a white spot on the north side of the hills. Go and enjoy, just don't be so fixed on your plans that you can't modify things as needed. We travel up in May and down in September.
