25K miles without tire rotation -- tread measurements for factory 18” Michelin Primacy A/S tires

[jonathan1994]

I have gone 25,000 miles without my first tire rotation. Yes, my life is THAT busy. Yes, I know that’s horrible. Yes, every 5k or even 10k is best.

BUT… you can learn from what I did.

2022 Maverick Lariat HYBRID with the 18” Michelin Primacy A/S. Original depth is listed as 8.5/32nds. I run 35-39psi with about 200# of bed cover and tools in the back always. My wife only had a trailer behind it twice, and we have only had more than 600# in the bed for maybe 1,000 miles total. Most miles have been paved 2 lane roads.

FL 6.1/32 FR 5.9/32

RL 7.2/32 RR 6.7/32

I took 8 measurements on each tire, 4 across in the grooves at 2 different spots.

1 The front seems to wear evenly across each tire, but overall 20% faster than the rear axle which makes sense considering the truck has a 60/40 F/R weight distribution.

2 The rear tires wear more on the inside and outside despite carrying less weight at the same psi. The inside wears more than the outside, probably from the factory camber.

3 The right side wears about 5-7% faster than the left. Probably due to the weight of the batteries and my passenger side toolbox (~50#).

So instead of the typical rotation pattern, I just did an “X” pattern swap and I'll try for 1 rotation for the life of the tires.

Also, how do I program the tires to their new locations?

I would raise the rear pressure a couple psi

This is great info, thanks for posting. What are you using for tread measurement, just one of the analog gauges?

Looks like you will have no problem getting Michelin's 45k out of them. I am going to have my second 7k rotation tomorrow so I will see what I have left then. Michelin recommends 4-6k rotations depending on wear.

you don't have to do anything to the TPMS after rotation unless you change the transmitters.

 

[RR - All the way]

FYI, the X rotation swap which you did is what is recommended in the owner' manual!!

How do you even get 25k out of a tire? Come to SW Pennsylvania. I got 17k on my 4k stock Pirelli’s. I could have maybe pushed them another few thousand but that is it. And I drive slow.
Got to love tar and chipped roads.

These mixed decimals and fractions are hurting my brain. Numbers don't work like that.

Thought it was just me...lol

17/64ths. There, I fixd it for you. LOL

I have 20K on mine. Mostly highway. Rotated 3 times, the last a few days ago. Dude at Discount Tire told me 1 is getting close and all 3 are about to get in to the "not too many more miles on em" category. FLIPPING NUTS!

He said new car tires often wear out quickly.......they are "softer" if that's possible.

Flipside is, Michelin has a replacement with an 80K warranty. Keep em rotated, if they don't last, you get credit on the next set.

Very frustrating.

See below from the manual. Straight back and cross up to the front.

Those are very small differences for never rotating. A rotation now and you should have optimized the life of the tires to the max by the time they wear out. I'm not sure I'd change anything other than to rotate them somewhat earlier in the future while monitoring their ware to insure no alignment problems have cropped up.

you don't have to do anything to the TPMS after rotation unless you change the transmitters.

You do, if you want the onboard TPMS display to accurately reflect the position of the tire that is low (or high), so you can correct it easily. And I, for one, would consider a "low pressure" indication, plus a "pressure dropping" warning on a front tire to be a "pull over IMMEDIATELY" situation (FWD Hybrid), where I might continue to the next exit if I got the same indication on a rear tire.

If you take it to a tire store, they will reprogram the TPMS system for you - often at no cost if you're a regular customer. I use Discount Tire 100% of the time for my vehicles, and they've never charged me for stuff like this, even for OEM tires. Guess they know I'll be back soon enough to purchase tires from them!

You can also purchase a TPMS scanner tool on Amazon, but for me there just wasn't any point. Discount Tire does my rotations as well, and they reprogram the TPMS as part of that service. With an appointment, my wait is typically a LOT less time that it would take me to rotate the tires at home, and my hands (and shirt, and pants) stay a lot cleaner!

Thank you for the recommendation, and thank you for your patronage!
