I’m intrigued, could you share the source of this information?
As far as I know it's what we have been told from my employer as common knowledge within the tyre industry. It's like Porsche cars must be fitted with N rated tyres which have been designed for extra grip on the wet.

I also had the same factory fitted Continental EcoContact 6 and found them horrible in wet conditions. Watch the video from minute 4, it has some interesting data on EcoContact (and e.Primacy).

Despite BlackCircles listing both SUV and non-SUV versions of the CC2 (both of which are marked a XL) with different prices and different fuel economy rating I shall go for the non-SUV version. Partly because an XC40 isn’t really an SUV, it’s just a jacked up saloon, and partly because the standard EcoContact 6 doesn’t appear to have an SUV variant.

Who knew that buying replacement tyres could be so complicated! Seems like smoke and mirrors to me.

Are the Vol and JLR more expensive?

OE tyres, the only ones that I have seen were fitted to Peugeot 108's only 5mm tread as the tyre cost was reduced for manufacturers. I have never come across any demounts that had tread depth less than 7mm. So I fitted CC2 235/55/18 104 XL H VOL because they are rated A for rolling and three peaks plus M&S. Because when I go away caravaning it's on fields not proper sites and mud is likely!

If you look on mytyres there are two different codes for EcoContact 6s in 103V Vol spec - wonder if they amended the compound of carcass ?

If wet grip and fuel efficiency class are identical for both I doubt they made changes to the compound. Would be interesting to see if there are tread depth differences, but I can’t find that piece of information online.

My eco contact 6 tyres had 6mm at the back and 5.5mm at the front after 1500 miles of sensible driving whilst breaking the car in. Volvo had no interest in replacing them for a tyre that was less dangerous on a brand new car - appears their concerns for safety don't extend to tyres.

I got my D4 XC40 AWD three and a half years ago and they gave me EcoContact 6 (235/50 R19 V XL) as summer tyres, which they just removed from a XC40 the salon employee drove that summer. They had some 4k miles.
This is their 4th summer and they have been driven for more than 32k miles. Still have tread above the borderline, still feel good and are a fuel saver! Winter ones (Pirelli) have some 25k miles and are still great!
OK, the car is driven mostly on highways and between 70-80 mph (115-125 km/h) with no heavy braking or turns. I thought I'd replace them before this summer, but everyone keeps telling me they are still good, which I also think.

So, I really don't know what tire type am I having and what are you all talking about (although, I know I'm a majority here). Are hybrid or petrol versions that heavier than mine D4 with AWD? The app says my car's Gross Weight is 2.250 kg.
