If that were a auto tire I would say that it shows classic signs of underinflation. Never knew that a bike tire would show that much less ever seen that.
Do you need a new tire.... yes, you need a new tire, but you don't have to put it on until this tire gives up the ghost entirely by coming apart or goes flat more often than you wish to fix the flat. But have the new tire in stock so you don't miss out on any good days of riding. Tube too if you don't have one already as a spare unless that is tubeless.
Corroded spokes don't bother me either. But if they are making noises just rolling along, then you might need to have the wheels looked at and their spokes adjusted. The bike shop here will check them for very little cost. But it helps if you take the wheels off of the bike before showing up at the shop with them. That time saved of you removing them from the bike sometimes might be the difference of them looking at them right now or telling you a day or two.
