M+S on it's own on a tyre these days is nothing more than a sales gimmick, unless it's accompanied by the "Three Peaks and a Snowflake" logo. Then the M+S does mean that they're usable in snow (colder temperatures).
they are for my D3 , owners book says H speed rating
can't see my disco ever doing 130 mph
would have thought they may be required on the newer rangies but certainally not mine
wouldn't think theyve got those markings, assume them markings are only on winter tyres only
manufactures quote mine as an all season/ on/ off road terrain tyre , which i assume is only by its tread and not by using the softer rubber that winter tyres have

My apologies. Finger trouble!
I meant to say that the M+S mark does NOT mean that they're suitable for use in snow or lower temperatures, although, many users in the UK will get away with using these types of tyres with no adverse effects for years.

If you have temporarily fitted snow tyres for the winter - many of them are way below the speed limit of the car. It's perfectly legal to do so if you don't exceed the limit of the tyres - and a sticker indicating max speed that the driver can see is recommended so you can demonstrate that you know this..

As for why LR picked H rated tyres I bet that is because the RR or Disco can go fast enough to need them, and LR don't want the hassle of two speed ratings in the supply chain, accidentally fitting a Disco/RR with Defender tyres... easier to just fit everything with the same H rating and spec it for the Defender as well.
This is always a good reference I found... http://www.btmauk.com/wp-content/uploads/2014/12/Replacing-car-tyres-important-information.pdf in particular they state that you only need tyres rated to 70mph - but it's usually a good diea to have better spec ones for braking and cornering reasons..

Theres a long writeup here which is quite illuminating..

many thks, a good read
surprising what u find out, know @brian47 is extremely knowledgeable concerning tyres
read this bit
As for the M+S mark itself, this is just a manufacturer’s statement that the tread, alongside the materials used in the tyre construction, is of a suitable standard to operate as a mud and snow tyre. While this is certainly better than a standard tyre

I do remember a discussion once when the other person said that there was no need for cold climate tyres in the UK because the temperature hardly ever went below -7degrees C.
He was wrong, cold climate tyres start working as they should below +7degrees C. And that temperature happens on many nights and even days in almost all areas of the UK during the winter months.
They don't just work better in snow, that's why I prefer to refer to them as cold climate tyres, but they're better in cold wet, cold dry. They corner and brake better in the cold too, even when it is dry.

I ran proper winter tyres on my previous cars for years and I could swear that the tyres had more feel to them even when it just a bit chilly rather then cold. When my current tyres (Geolanders) expire, I will probably get winter tyres again for the Disco.
it's opened my eyes after reading through the links ,ref winter tyres and certainally know the north of the uk gets considerably colder than minus 7 c, that's why i'm a softy southerner
didn't realise at first they also improve cornering , braking etc due to there special compounds
can't argue with such irrefutable evidence that winter tyres should indeed be fitted , especially in the northern parts of the uk due to the lower temperatures
also didn't release of the different mixtures that winter tyres provide, i.e. winter/ off road etc
imagine there pretty good off road due to there softer materials ,
i'm also going to invest in a set of winter tyres when mine wear out , never had them before and will be interesting to see how they differ
wonder if u can mix them, i.e. getting a set fitted on the back and m and s tyres on the front

I can't see any reason why not, but that said, as the winter tyres will provide more grip, would it cause any issues with the TC?

I strongly recommend to not do that.... it can cause many problem not just TC, don't ask me to explain please

id be interested to know ,mixing tyres is a poor idea especially on an equal four whee drive but tc is only goes off differential wheel speeds above whats given for turning in full lock etc

If you'd rather not type out an explanation, do you a web link or something?

I'd like to know too. Can't see any issues with the TC. Else it be like saying having the front wheels spinning on a muddy slope will cause issues with the TC.

Coo! You lot are quite pedantic about tyres. The only thing I look for is a bit of tread and that they are round and pumped up. I could understand all this bollox about speed rating if you had fast cars that corner really well but come on. When you are looking at a car to buy, do you check the tyre reference letters and numbers with the same detail as the chassis?
