Question about swapping out just 2 of my tires for new ones.
It seems one of my rear tires has a radial tire pull and discount tire has agreed to replace it and my other rear tire. I was told that there was a minimum amount of tire thread required that would allow only 2 tires to be replaced rather then having all four of them replaced.
Currently, my tires have 8/32's of thread remaining and come new with 10/32's.
Should I be ok replacing just 2 of the tires for new ones and running the 2 older ones at the same time?
I know normally this is a no-no, but they said it'd be ok since my tires aren't very worn.
These are the tires I have...

If they are too far off in tread depth and you only want to replace one, you should have the new tire shaved down to match the other. If you are doing two, then have them installed on the same end of the car. This way both sides of the differential are turning at the same rate. That's ok to do, just doing one fresh mixed with a worn down on the other side can cause issues.

Neal, thanks for the info. Yeah looks like i'll be getting both replaced. I'll see if they can shave down some thread, but I doubt they can do that. If they can't, I'll just run both on the same end. The tires that are on there now haven't worn much at all, they still have 8/32nd's left and they come with 10/32nd's new.

I know this thread (note threads are in forums and treads are on tires!) is a year old, but i'm having a wicked case of radial tire pull on some tires that are almost halfway through their tread depth. are you saying it's ok to replace the front two tires and leave the rear two as the halfway worn ones?

Depends on what Mitsu says is an acceptable tread depth from front/rear on the car. I know that my Audi with Quattro can have a 3-4/32nd tread depth difference from front/rear before I have transfer case issues.

if i call up a mitsu service department, you think they'll actually know the answer to that?
and that sounds sarcastic, trust me, it isn't. i really just wanna know if you think they'd know.

Yeah, so that doesn't actually say anything about the max difference between tread depths.
The really strange thing is that a stock tire compared to the spare is as follows:
Why is it OK to drive on the spare very much at all when it has 1.3 inches of difference in diameter?! That is huge relative to 2/32 or 4/32

Right, I'm not saying that you should run on spares all the time or anything... just that you would think Mitsu would have put some kind of a major warning that your transfer case might explode if you run on it for too long. I didn't really even think of the difference in size when I got caught off guard on a recent road trip and had to drive ~ 70 highway miles on it when I popped a tire. As far as I know all warnings related to it are about maximum safe speed (for both construction and safety).
...although I guess saying that running a spare can destroy your transmission might make for an easy legal target.
I guess this will make me feel a little better about driving 15 miles on a .622% difference in rolling diameter before getting the tire shaved....

Zing, sorry about that. Good catch!
Only thing is the size difference is even greater
