You notice a strange noise coming from one of your tires as you are driving. You're not sure which tire is making the noise though and a visual inspection doesn't show anything obvious wrong.
You decide to switch the bad tire and replace it with a good tire.
What is the fewest amount of "moves" you could perform to determine the bad tire?

With two new tyres you can do it in 2 changes.

You could fix the problem in a max of 2 changes with 2 new tires but would you be able to determine the bad tire?
2a)If noise persists its one of the back ones so just replace with one of the ex-front ones.
2b)If noise has gone its one of the front ones, put one of them onto the back to find out which.
Originally posted by wolfgang59What if the problem goes away after changing the front two? You still don't know which of the two were bad, you just know the problem went away. It could have an internal defect not visible.
1. Change the two front tyres for new.

Originally posted by sonhouseIn two changes, I think you can either a) identify the bad tire, or b) fix the problem, but not necessarily both.

Even for driving a car only one change is needed to determine the bad tyre.
You do that James Bond trick where you flip the car up on two wheels.
If you cannot hear the noise you know it's one of the tyres n the air.
You change one of those tyres. Drive normally.
If you still hear the noise you have determined which tyre is bad.
It may be possible to do with it no changes by covering each tyre with
a fine powder and driving 50 metres. The tyre makng the noise will
have shaken off the most powder. (I think.)
