If I understand this correctly the puncture to flat I’ve just recieved can’t be repaired?
Its about 5mmm slice on the shoulder hissing air, tyre deflates within 15 mins. The tyre sealant solution will hold it to my choice of tyre shop. It’s a rear on a RWD.
The next question becuase it’s a fairly new conti all season, can I replace the one tyre with a new one (7mm) with the other one at 4mm tread depth? Seems a waste to throw the good one away.
I don't see why not – as far as I am aware, only certain old 4x4 systems required both tyres changing (Vauxhall Vectra was one IIRC).
Just don't fit cross-ply and radial on the same axle 😉
They never repair shoulder or side-wall punctures as far as I know. I had a puncture fixed recently and talking to the fella I mentioned MTB tyre sealant. He said if you put that in a car tyre he'll just bin it if it punctures.

it’s be the same tyre. Ffs, got 13 months / 4k miles out of the punctured one 🤷♂️
Not a bad idea in case this happens again….
Edit, just look at the service report, 2 weeks ago and when the car was last driven - all tyres at 7mm, god knows where I got 4mm from. Think I’ll get just the one… and seeing it’s the left hand side rear taking most load from roundabouts it’ll probably even up over time 😂
If it's an audi quattro, it's recommended to change both tyres on the axle.
It’s a BM 320d. But FFS, I was reviewing the BMW health check video they send you for the depth check, and I found the prior one for which they said they were 6mm. So they’ve added a MM in 6 months ? 🤔

Not just old . Xdrive and quattro also hate odd tires . my mates ABS on his Xdrive Beemer went mental and he was chasing a mad vibration for ages - till they changed his tire.
Resulted after the BMW garage replaced a single tire on the drivers side after he was tBoned.
New matching tires cured it.
Crossply tyres were probably last used in the 70's and made for Morris Minors, Ford Anglia's and maybe if you had a 1964 Austin 1100
Even an Austin Allegro would have had radial tyres
as long as the one that's staying is newish - you say 6-7mm - then should be OK.
A new and an old with very different tread (and grip, and....) I wouldn't chance.

And rally cars and various race cars . Still made to this day.
You can get it repaired but only at a specialist if you can find one.

This is excellent advice. But also, don't fit them on the same car. If you do, fit the cross-plys on the front, radials on the back.
BITD I fancied myself as a driving god, potential F1 champion, inherited an old Vauxhall Victor with cross-plies all around. We went down to the wreckers yard and bought two half worn radial tyres on rims that fit the Victor and fitted them on the front assuming that our driving prowness would make up for a car where the back axle was constantly trying to overtake the front. Luckily for us, it was drizzling the day we tried it so we never got above about 40 mph, the bloody thing would just fishtail in a straight line and you'd need the reflexes of Aryton Senna to keep it within your lane. Utterly terrifying experience.
I know, I was just referencing the shitty 1970s public service announcement
That's a '68 Morris 1100/1300 rather than the Austin
No wonder all these British car makes ended up BL, the were all making the same cars and competing against each other
Wolesley, MG, Austin, Morris, Riley , Vandem Plas
The posher ones had walnut veneer and twin SU carbs but they all had the same failing rusty rear subframe and chills
I had a B reg Morris, cost me my wage packet of £22.50, great wee car it was
Theres two different converstaions here...
1.The puncture can be safely fixed or not. If yes, no problem.
2. If not, and the car has AWD, LSD, 4x4 etc, then you want the same level of grip on both sides of the 'axle'.
2a. That might mean buying two new identical tyres if they are very worn, you don't want a tyre on one side with 2mm tread, and one with 7mm on the other.
2b. Dont mix and match tyres on the same 'axle'.. you need symmetry in terms of grip and tread depth.
