Saw something similar last year, shortly before investing in a set of Vredestein wintrac 4x4s from AJS. 2016 D4 Landmark SDV6 (Euro6), Zanzibar (late run D4)
2009 D4 HSE TDV6, Bali blue (first run D4)
2007 RRS TDV8 HSE, some blue

The average temperature here in the west country has been 13c since fitting winter tyres to our Saab in October
Some of the winter tyre tests are now inc. summer tyres to compare braking at higher temperatures . The results aren't as dramatic, but winter tyres take far longer to stop than summer tyres when it's warm and dry. I've noticed this with the Saab and it's why I always cringe when the subject of running a 3 ton D3/4 all year round on winter tyres comes up as it frequently does.

Not so in the testing we have done.
And many customers using my favourite flavour of winter tyre on all types of 4x4 are experiencing "NO" problems what so ever.
I still think it best to change to winters or summers when needed, but some can't be bothered.
I run a good AT tyre all year, because it suits my requirements, but if needed I have a few choices.

Last year I went from worn Scorpions to new Grabber UHPs the day the snows hit. The UHPs were excellent. I then got my hands on a brand new pair of Conti winter contacts (same as those in the test). The difference between new UHPs and new winter tyres was significant. I'm absolutely sold for that reason. With a young family I'm absolutely certain it's worth the dosh.
One last thing, if you're thinking about it, don't wait too long as when the snow falls prices will rocket and availability will tumble.

I ran wintracs all last winter and they were excellent. However, in the April heat wave I had the unpleasant experience of a skidding disco . Just a small slip coming up behind traffic at lights but it gave me a scare. Swapped back to my Scorpians that weekend. However, will be putting the winter tires back on soon!

Maybe wrong forum to ask Andy
Disco 2 we run on BFG A/T 235/65(?)/16
Defender 110 on BFG M/T 255/85/16 We have a pair of Pewag chains for the 110's
So what winter tyres would you recommend for our vehicles?

The most favourable test that I've read showed a winter tyre only 10% behind a summer tyre in braking tests during warmer weather. It was the 2010 Auto Bild All Season Tyre Test, comparing winter, summer & all season tyres.
But that was on a car which weighs a lot less than a D3/4.
Here's the test:
"The all season tyre had similar properties to the winter tyre, offering a little more grip in the dry and wet, and a little less grip. Summer VS Winter tyres - Warm weather performance
There's no arguing that winter tyres offer more grip than summer in temperatures below 5-7c, and that below 0c that performance gap is even wider, but how do winter tyres perform when the sun is out and the temperature is high?
To answer this we've used the 2010 Auto Bild All Season tyre test which was conducted during the summer months. Primarily an all season tyre test, Auto Bild were kind enough to include a summer and winter tyre for comparative purposes.
The results
Unsurprisingly the summer tyres won the dry and wet tests, but the winter tyre averaged just over 10% behind it's summer counter part which is closer than expected. During the snow test, the summer tyre had less than 50% of the grip in in the snow. This just goes to prove the naming terms the tyre industry use are too generalised, as we're quite confident another brand of ??all season tyre?? would mirror the summer tyres performance.
Our advice? If you commute during the winter and rely on your car to get to work, winter tyres will give superior grip on cold mornings without sacrificing more than 10% of summer tyre performance during the odd freak warm day.
The summer tyres were the Bridgestone ER300, the all season tyres the Vredestein Quatrac 3 and the winter tyres the Dunlop Winter Sport 3D".
Where I live in the west country the average ambient temperature falls below 7c for probably no more than 2-4 months of the year and in the summer can reach highs of around 30c.
I'm not aware that Vredestein have invented a magic tyre compound, their winter tyres have a higher silica content than their summer tyres.
I remain totally convinced that any suggestion of running winter tyres all year round is wrong.
But the facts are there for all to read and you can make your own minds up.

All the tests in the world will differ from who and what is being tested.
Our tests do not agree, sorry.

Typical behaviour for a high silica compound tyre in warm weather. But interesting to hear it first hand from a Disco owner/driver.

I agree, the Auto Bild test was the most favourable towards winter tyres at higher temperatures, most of the others were higher than the 10% difference. Inc. iirc the recent Auto Express test.
BTW, I'm not knocking your test Andy, I wasn't there and haven't read the data produced from it.

Winter Tyres
Converted just ordered 18 inch wheels and Pirelli ice and snow tyres to be fitted end of this week. I was unsure which way to go as per my original post I was intending to run BF Goodridge TAs on 17s but the more I look at the winter tyres they seem to stack up and I will fit AT after the winter
Hopefully I've made the right call time will tell ! Gerrymac
