I had a set of Kuhmo KL71's on a Landcruiser, and while I found then to be very capable off road, on road was a different matter, firstly they are very loud, and they scare the out of you in the wet
The Coopers all be it still noisy, behave very well in the wet
Oh and was the TJ a 2.5 or 4 ltr? Spooky that its the same color And even more spooky its parked outside Christ Church on the common! Thought that I recognised the back ground! Yesterday I couldn't spell Engineer... Today I are one!

It was a 4.0 and much fun! Yes its Christchurch Chorleywood just up the road from me where my kids went to school. The TJ was bog standard when I bought it and I enjoyed the modification.

Same colour as the D3 or something else?

Hope I have done the right thing I have just taken the plunge and purchased these on here.

So your going to be 3.5 mm nearer the ground and you'll accelerate a fraction quicker, oh and you'll be going fractionally slower than the displayed speed, big deal!
If your that worried about it, find someone with a sat nav (after sales) that displays the current speed, they are very accurate, whizz the car up the road, I surgest that you employ the cruise control, and check the speedo against the sat nav. My FFRR does 69 MPH when the speedo reads 70 MPH, thats with std tyres. Yours will probably do 68 MPH when it says 70 MPH.
My Jeeps well out, reads 25 MPH when it's doing 30 MPH That will teach me to play around with wheel sizes  Yesterday I couldn't spell Engineer... Today I are one!

I am already rolling on 275 45 20s so no difference except for tread, Craig at Can Tech recons I have got a set of RRS wheels on as they are Stormers with directional grabber road tyres, they hold the road well.
So a set for Winter and a set for summer all is good.

Cooper LTZ are not winter tyres. Chunky tread does not make a winter tyre - it's probably counterproductive in every winter situation but deep fresh snow.

Mine work fine in rain, dirt, sand, mud, water, snow, sleet. You name it. Love them.

Maybe, but they aren't winter tyres and aren't sold as such - not a winter compound, not a winter tread pattern. Coooper make winter tyres but the LTZ isn't one of them.

unusually i find myself agreeing with trommel, the ltz is an all terrain tyre and not a mud and snow one,

I'm not trying to put a fly in the ointment, but aren't the LTZ marked up as M+S? I always took that to mean mud and snow, and while I will accept that they are not full blown winter tyres, surely they are alright for the white stuff.
The only thing that I've come across that tripps up a M+S tyre is ice, and as far as I'm aware the only thing that will cope with that is studded winter tyres, and Kevlar underpants  Yesterday I couldn't spell Engineer... Today I are one!

they might be marked M+S but that could stand for mud + sand...

cooper do do a specific mud and snow tyre in their range.. ... - .- -.

So M+S isn't worth the rubber it's printed on
And I know that Cooper do Mud tyres in their range, I've got them on my Jeep!

One of the markings on the sidewall of a tire is a Uniform Tire Quality Grading or UTQG grade.

The tire's UTQG rating provides information on three aspects of the tires durability and operational characteristics.
They are:

tread wear,
traction
and temperature.
The tread wear number comes from testing the tire in controlled conditions. The higher the number, the longer the life expectancy of the tread.

Since no one vehicle will be subjected to exactly the same surfaces and at the same speeds as the controlled conditions, the number can only be an indicator of expected tread life in 'normal conditions'.

The rating is based on a percentage of the projected wear life. For instance, a tire rated at 400 has a projected life twice that of a tire rated at 200.

There are many factors that influence wear, such as vehicle speed, road surface, climate, vehicle wheel alignment, and the driving characteristics of the driver. As such the rating can only be an indication of the anticipated wear characteristics of the tire in controlled conditions.

A traction rating is a letter based indicator system. The rating is based on the tire's ability to stop a vehicle on wet concrete and asphalt in a straight-line situation. It does not indicate the tire's cornering ability.

The Tire traction indicators are rated as AA, A, B or C. AA is the highest rating.

It is important to note that the test and relevant rating does not indicate hydroplaning resistance, dry or snow traction capacity, or cornering capability in wet, dry or snow conditions.

The Temperature rating of a tire is a letter based on a controlled step speed test. The possible ratings are A, B, and C. The rating is a measure of how well the tire dissipates heat and how well it handles the buildup of heat. Excessive heat buildup can reduce tire life, or even lead to tire failure. However, while temperature plays a role in the speed capability of a tire, it is not the only factor.

It is important to remember that these ratings are based on standardized test conditions, and the tests do not reflect tires that are operated in overloaded, under inflated, and/or misaligned conditions. It should also be noted that when rated one tire might be a low "A" and another a high "B", so the actual operating performance differences might be relatively small.

It is not uncommon for there to be differences in UTQG ratings within a given tire design. Sometimes a particular vehicle manufacturer will require certain properties for the tires supplied to their vehicles, which can affect the ratings, both positively and negatively.

Sometimes there are differences between small sizes and large sizes of tires in a given design. All of these aspects can affect the actual rating that is put on the sidewall.
