My truck is fine at our altitude but 85 will ping driving in the mountains so I go no lower than 87 with an occasional 91 tankful to burn out the bad stuff.

out here today it was 90 degrees, and the run from DIA with luggage and a/c going it was pinging under load with our 87 "mid-range" colorado octane. most of the time it's OK, but pulling the tunnel during boarding season brings some ping. never an issue with 91, if you can afford it.
