Where did all the tread go?
Discussion
Not my car, but I spotted this rear wheel some weeks ago in a parked car:
The points of interest are:
(1) the opposite side tyre (still) had tread markings go across the tyre from the edge to the outer circumferential band. You can probably work out that the tyre in the image originally had them going across the tyre but they have worn flat;
(2) it's a "22" reg plate car that must have been no more than a month old when I took the photo
(3) it's on a big heavy Volvo SUV
I must admit I was puzzled when I saw one tyre looking entirely bald except for the circumferential bands, and the other side still having the crossways tread markings. Are they essential for safety and would the tyre fail its MOT, as long as the circumferential bands were more than 1.6mm deep? Or are the bands all that counts for MOT? How could the tyres have worn down that quickly? And if so, why bother having such a pattern if it wears down within a few weeks?

I'm guessing there's something wrong with the suspension or geometry on that side, pretty impressive..The points of interest are:

Maybe was a front tyre and rotated to get some more wear out of it, maybe the driver lives in Milton Keyes, maybe had a puncture and/ or damaged a wheel and borrowed a wheel whilst waiting for replacement.
Certainly would like to know.
Found a pair of front tyres similar to that on a noughties hot hatch, except completely shredded with the excess melted rubber stuck to the inner wheel arches, brand new unregistered car which i picked up from the docks as part of a load...obviously reported it immediately which is when all hell broke loose, doubt it happened in the UK port (cameras everywhere) which meant it happened at the export port.

Lifted this from another thread but it shows the Michelin PS4S has a higher wear, more grippy compound on the outside edge.

Wouldn’t surprise me if the P Zero had similar treatment.

Some UHP tyres have very minimal lateral tread sipes on the outside shoulder but I'd be surprised if this kind of tyre was being fitted to Volvo SUVs from factory and the OP has said that the tyre on the other side was the same make and model and apparently has tread there.
Given that the car is so new, I'd say that it's not the original tyre fitted to the rear of that car. Very unlikely to be able to inflict that kind of wear on the rear of a big SUV in that amount of time. Any misalignment that could cause that wear in that time would be very apparent to the driver.
Maybe the wheel or tyre was defective or damaged when it arrived with the supplying dealer and they sent it off with a substitute while they waited for a new wheel or tyre.

You'd be surprised how many people would drive a car with a suspension issue thinking it was 'normal'. Never over-estimate the general public..Given that the car is so new, I'd say that it's not the original tyre fitted to the rear of that car.

You'd be surprised how ignorant drivers may be to an alignment problem and also being on the rear it may not impact things as much as you would think.......Given that the car is so new, I'd say that it's not the original tyre fitted to the rear of that car.

That is an alignment issue
The tyre hasn't cracked , the tread hasn't fallen off, it's simply mis aligned, I would suspect the toe adjustment is a mile out either from factory or the owner has bunged it into a curb or something which has caused a mis-alignment
Might have been on a track day going round in 1 direction (anti clockwise, turning left a lot) or handling day on a runway? Big heavy car like that could easily kill a set of tyres.
Some sort of police evaluation vehicle or enthusiast?
One of the first things I do with a new car is to find out its limits on various IAM days, including on track.

That would be quite incredible wear in 1 month......even if thats on a motorway mile muncher.
So others are as perplexed as me. The tyre the other side was the same type, just that it had lateral tread whereas this one didn't. So seems rather unlikely to have been a temporary swap onto a defective tyre as implied by someone above.Are tyres required to have lateral tread, would this be an immediate MOT failure (is the MOT even relevant in a one month old car?) The circumferential tread was way more than 1.6mm deep still.
