21" tire tread wear and mileage.

[mkg3]

At 3000 miles of mostly flat and straight highway driving I got 9/32 on outside front, 10/32 on middle front. 8/32 on outside rear, 10/32 on middle rear.

Since you said straight and flat highway driving, your wear may show that your under inflating your tires.

There's a negative camber in the front that would cause the outside to wear slightly more than the middle or inside, but the rear is the reason why I think it might be under inflated.

Do you carry a load most of the time in your bed? Have you checked your tire inflation?

i checked once and they were on target. Will check again. Thanks for the reminder ?

Whole nutha level on tire expense for me if 10-15k is the norm. $$$

Yep. I'm hoping that turns out to be false. I know these tires won't last as long as other vehicles... But I was hoping for at least 20-25k.

BEV's are a tire companies new best friend. Add the 3.5 ton R1T to the list.

Time to create a long play position in some names....Short brake pads, long rubber.

I think this is location-dependent. The Costco locations I've checked all say they don't do rotations, at all.

In southern CA. All do

Would also need to know inside tire wear to fully assess that.

All driving conditions being equal. Is the 20" AT tire less likely to get a flat than the 21s..22s???

Another factoid - HQ will tell you that the SC have the ability to repair tires, but that is not true. I had a leak, and asked because I had an upcoming service visit, so didn't want to make an extra trip to Discount if they could do it. They said the SC could. When it got there, the SC confirmed I had a puncture, but they didn't have ability to repair. That being said, the puncture was in the shoulder and couldn't be repaired anyway, so they just replaced it ($425 with tax for the AT, which is same price as Tire Rack). I think they said the plan eventually is to have ability to repair tires, but not currently. This could also have just been that one center (Houston).

I picked up a nail within a few weeks of getting my truck and the Nashville service center was able to repair that tire.

That's a very broad question that depends on driving conditions. It is unlikely that someone with 22s would go "off road".

That said, in general, the 20s should be less susceptible. Deeper tread, harder compound, would make it less likely that a puncture from a nail with less length than the 20s tread depth would make it through, while the same nail may make it through the other tires.

More sidewall on the 20s also make them less likely to get a sidewall blowout from a deep pothole.

Passenger side rear tires seem most prone to punctures.

Debris is on the passenger side of the road and your front tire kicks it up and the rear tire usually gets the puncture.

In the 22” size Pirelli does make a tire with a 800 tread life rating. A little less load capacity than the OEM’s but unless you plan to test that 11000 lb. towing capacity it shouldn’t be a problem as they are only a few hundred lbs. less than the OEM’s rating.

How you drive can make as much impact on tire wear as how much you drive.

My first i3 didn't make it to 13K miles before I had to replace the rear tires. That's because I was gunning it at every light - and every opportunity I got because the torque and speed, especially off the line, is addicting.

I quickly realized I was going to blow through thousands of dollars in tires so I started putting the car in "comfort" or "eco" mode more often - and laying off the accelerator, and it make a huge difference. The second set lasted me over 20K miles.

So preliminary data would suggest a life of roughly 10-15k miles on a set. We'll see how that evolves as the data set grows larger.

Holy Fook!
