I have a technical question for the community. 

My dad's 4WD Honda CR-V picked up a nail in a non-fixable part of the tire.  2 different tire places have told him that since it is a AWD vehicle that he needs to replace all 4 tires at the same time.  I call bullsh*t, but pages of Google results have people who *think* that the same thing.  The theory is that since the new tire is a different overall diameter than the other 3, the traction system thinks that the new wheel is slipping because of a different wheel speed.  The constant slipping causes the differential to be always engaged and wears it out early and quickly.

This is all news to me.  I hesitate so quickly trusting tire shops and people on random forums that think they know or know a guy who's brother's girlfriend has the same problem.  What do you say OVR'ers?

depending on how many miles he has on the old tires
is the tread pretty worn?
depending on how comparable it is to a new one you could get by
it is for sure suggested to keep them similar though

I saw the car yesterday and looks like the other 3 are about half / more than half worn.  The nail is actually holding air really well with no detectable drop in PSI in the last 3 weeks since he picked it up.  I think he's going to replace all 4 anyway, but at least made sure his spare had air in it.

Maybe this more of an FYI.  I would have just thrown a new single tire on and never looked back.

Does the CRV have full time or part time 4WD?  If part time, you could probably get away with replacing a pair.

The other cheap alternative woud be to scour the many used tire places for the same make and size of tire.

Tire Rack shaves tires for $25 to whatever depth you want. Buy a replacement tire from TR, have them shave it to the depth of the other three good tires, and call it good.

I remember they do that for autocross/track tires.  Thanks for reminding me, a quick google came up with the tirerack article about doing it specifically for 4WD vehicles.
