AKo unimproved ip vs an 80/10

villain is 80/10 over 35, but also makes what seem to be spewy steal the pot kind bets. Theyve worked so far and i havnt seen him show down much - he can fold if the pot starts getting big.

CO ($10.32)
Button ($10.05)
SB ($11.79)
BB ($16.42)
UTG ($8.70)
Hero (UTG+1) ($10)
MP1 ($4.97)
MP2 ($8.90)
MP3 ($11.63)

Preflop: Hero is UTG+1 with A, K
1 fold, Hero bets $0.40, 6 folds, BB calls $0.30

Flop: ($0.85) 8, 7, 5 (2 players)
BB checks, Hero checks

Turn: ($0.85) 9 (2 players)
BB bets $0.40, Hero calls $0.40

River: ($1.65) 8 (2 players)
BB checks, Hero checks

Total pot: $1.65 | Rake: $0.08

I planned on folding to a river barrel.

Is my turn call silly? Turn did make a lot o draws which makes me lean more toward fold now but what about if it was a blank like 2h?

edit: at the time i still put him on a v wide range at turn, presuming he'd make a stab at the pot with air since i'd not cbet the flop..is this dumb?
