My ML came with mismatched tyres front to rear. All of them cheap Chinese carp.

I’ve been offered a set of used BF Goodrich All Terrains for a keen price (a set is nearly £800 new). Two at 4mm tread, two at 7mm.

Is this likely to be too far out of tolerance? I was thinking I could fit them and drive it and if it doesn’t throw a traction control fault, it’s all good. If it does, I could get two of them skimmed a bit.

Any thoughts? I’ve read a few people saying they’ve had similar differences with no problem but I don’t know enough about it

Not too sure what you mean by "Get them skimmed a bit" but it sounds from your description of the tyres as if they are a little out of kilter wear-wise: well, for me anyway. The two with 4mm tread depth are not far away from the wear safety bar.
The best solution is to bite the bullet and buy a set of new tyres, dependent on your budget and my advice would be not to try and save a few pence where such a safety aspect is concerned. Get the best you can afford.

They'll be fine.

Depends on the price though.

I can afford the new ones, but wouldn’t spend that much on tyres for a car that’s probably not worth much more

I’d probably get Yokohama or Goodyear all terrains otherwise. But these would be next to free so it seems worth a try if they’ll not do any damage

They've come off a pickup, so the rear tyres have worn quite a bit quicker than the front
Oh, and I meant that the 7mm tyres could be shaved to 4mm to make it match. This is more of an effort to reduce waste than to save money, as I'll just go for brand new Yokohama Geolandars or similar once I've used them up

Jimmy, I didn't mean to offend you with my comments. It's just that tyres are an essential safety asset on the car and I
personally would think hard about doing this. I don't think I have ever heard of tyres being "shaved" before but then I have
led a very sheltered life!! angel

No worries goddo, no offence taken!

Tyre shaving is fairly common for matching tread depths on 4x4s,
I think smile also in some race series that have specific tyre regulations
