Opinions on replacing one tire

And forget about tire rotation?

Since our cars only have 4 tires, you would rotate normally after the rear tires have been on for a while. The rears will go to the front axle, and the fronts cross to their diagonally opposite positions on the rear axle. ??

The exception is on an FWD only car where the new ones go in front and the best of the olds go on the rear. Since we have either RWD or AWD, this is moot. ??

I understand, ant totally agree - newer tires need to be in the rear. But after another 10K miles they are still newer, so will you do the normal rotation at this point? Or get a new pair and place it in the rear?

Isn't it better at some point, if you want to keep the car, replace all of them?

Once they are within 2 or 3/32 then you are fine. You just don't want fresh new tires on the front with older half-worn tires on the rear. with 12k miles on them, wear would be close to 1/32 with normal driving.

I had the same thing happen to me and I replaced 2 tires only. Then, I started getting "AWD not available" errors. This happened at highway speeds after a certain length of time.

One of the motors was overheating due to the slight difference in tire diameters from front to back (one set was spinning at a slightly different speed).

After a few minutes, AWD would reengage, then drop out again as the motors overheated. This would continue over and over again.

Replacing the other set of tires was the solution for me. If this set of tires gets half worn and I get one that can't be repaired, I'll just replace all 4.
