Shaving new Tire for subaru AWD

Thought I would ask this question in this forum, as from what I read here, you guys seem pretty smart on mechanics.

So here is the story. Wife picked up a large hole in the right rear on our 2015 Suby Forester ( with 15K on the clock). Tire is not reparable. So options are 1)Replace all 4 tires, or 2) Dealer says they will get same tire and shave it down so it matches wear on the other 3. They say all will be peachy.

My understanding is Suby AWD, is extremely sensitive, and if tires don't match as to size (as in tread wear), you will blow the Tranny.

Until yesterday I did not know one could shave a tire. So any thoughts would be greatly appreciated.

Mod If I posted in the wrong place I apologize, please move as you see fit
  • If there are 15K miles on the original tires, I would go ahead and replace all of them. It's not like they are brand new. They are probably 40K mile tires so you are at almost the halfway mark.
  • As an afterthought, from what I have been told, and what I have Googled . Subaru's, Are in class by themselves when it comes to this sort of thing. Other make AWD's are much more forgiving.

    I am not trying to go for the cheapest option. However if I don't have to replace the other 3 tires, and can just have them shave the one, that would seem smart to me.

    I am just concerned that shaving a tire would create a whole new set of problems. ( as in tread, would be affected, and screw up handling in an emergency situation) Which is why, I posted, to gain wisdom from you guys.

    I very much appreciate anyone who takes the time to post and for your opinion
  • That has been done for decades to "true" an out of round tire. I'm surprised that the max 1/2 inch tread depth difference would be a problem, though.
  • I vote for a shave. Better to take the safe course and spend the few extra dollars than to replace costly drivetrain components.
