Replacing one tire on AWD?

[Colorider]

During the last cold snap, I had a tire drop to 30 psi and it threw a low pressure alert. I pumped it up and it hasn’t dropped since. However, yesterday I looked more closely at the tire and found an electrical staple in it. I know from a similar experience that Costco won’t repair a staple so I am really bummed—the tires are Blizzaks with only 3,000 miles and were a $1,000 for the four of them…

I know in prior ICE cars with AWD, running different size tires is frowned on because the difference could cause an issue with the differential. Is it possible to replace one tire with an electric motor? I would hate to replace all 4 tires…

Also, would an internal patch fix a staple? I am going to change back to my all seasons so I will have the Blizzaks off and could repair from the inside.

Usually the location of the puncture determines if the shop will make the repair. Where is the staple?

A new tire won't affect the sensors in any way.

The staple is enough in the tread that it could be repaired if it were a nail.

I am not concerned about the sensors though, my concern is the rear differential (or whatever deliveries the rear power in the Mach E).

If the puncture is not within about 1” of the edge, it’s reparable. If Costco won’t do it, go to a tire shop. I have similar issues at Sam’s Club, they find all kinds of excuses not to fix a tire. I don‘t take my tire business there any longer.

The proper way to repair a puncture is with an internal patch. Discount Tire does that. @Colorider there are numerous ones by you.

Thanks, I will try them. I have purchased tires there for years before Costco and this is a reason I should probably go back there…

Go to a place that knows how to do an internal patch.

Typically for AWD if your tires are all wearing evenly, you need to replace all the tires when a new tire would be more than about 4/32" (3.175 mm) different from the others. I'm guessing that unless you've been tearing up your tires, you're still within the reasonable replacement tread depth. You can measure it and look up the tread depth at new to confirm.

The transmission gear set is able to deal with variances between wheel speeds. It will be fine.

The rule-of-thumb is that a hole in the tread is repairable, a hole in the sidewall is not. Most reputable tire repair shops only use internal patches. Take it to Costco.

Previously it’s not that it was a staple that made Costco refuse repair, it’s where in the tire the staple was.

My wife had a similar staple and Costco wouldn’t fix it. In fact, we had to drive home on the spare because they wouldn’t put the old tire back on (obviously not an option on the MME…).

They should have known they wouldn’t repair it before dismounting.
I assume Costco told you you’d need 4 tires. What did you end up doing?

Bought 4 new tires and 4 new rims since I couldn’t get my favorite Michelin Defenders in a 20” and was sick of the bad tire selections in that size. They got me I guess…

If you got them at Costco, I think you get free road hazard insurance with them.

Your right with AWD ICE typically is there is more than 2/32 difference in the tread depth you need to replace all 4 tires. That's because the ICE setup has a transfer case EV has two motors and differentials in the front and rear = tread depth does not matter
