After 40k miles the fronts are on 4mm. The easy choice is to go with Verde's again but National tyres has a special offer on zero's but struggling to find what the real differences are esp from the manufacturer.....;

​SCORPION VERDE™ ALL SEASON is a Pirelli’s Crossover & SUV tyre developed with focus on safety in a variety of conditions. The lateral stability and the traction on wet, ensure all season performances. SCORPION VERDE™ ALL SEASON features the M+S marking engraved on the sidewall.

SCORPION™ ZERO ALL SEASON is the UHP SUV M+S product developed for premium and prestige OE Car Makers engineered to maximize the performances during all the seasons, in various driving condition, also on light snowcovered roads. The perfect choice for sporty SUV, it offers excellent performance on dry and wet and is the perfect fit for every vehicle. The compounds combined with the asymmetric and optimized pattern provide UHP performance during All Seasons, provides high levels of safety and comfort and minimizing the noise level. 2012 TDV8 Vogue (L322)

You’ll be happy with either, so I’d just go for the best deal you can get.
IIRC, Verdes apparently get a bit more mileage, but Zero’s have the edge on performance, so your style of driving will largely dictate your choice, perhaps in London, Verdes make sense?
Make sure either have the “PNCS” stamp on the sidewall, (not old stock without noise-cancelling).

I am, (and drive like) an old f*rt, so it’s Verdes for me!  “If it ain’t broke, don’t fix it” -where’s the fun in that?

I'm most definatley a 'Verde driver' and reckon I could have got 50k out of the current set if I had rotated them....... 2012 TDV8 Vogue (L322)

That's bloody good mileage from any tyre, IMO.

Is there much in it though, really? I don't know. 2012 Vogue TDV8 in Aintree green

I [i]almost[/i] was going to say: “If it ain’t broke, don’t fix it”

Sceptically precise, Toby1kenobi: probably 90% Marketing Bullsh*t anyway, trying to corner both “steady” eco drivers and “sporty” boy racers at the same time with minimally cosmetically different products.  “If it ain’t broke, don’t fix it” -where’s the fun in that?

Just put some of the zeros onto my 4.4

I went 4 new Zero's as well 255/50 R20 's and PNCS, made a difference to my ears noise wise

I was sceptical at first but the price I got was almost the same as Non PNCS, so it was a no brainer !

Went with the Verde's again. Noticably less harsh ride at slow speed despite Kwikfit using the fully loaded pressures so wonder if tyres age harden or the design has changed since the last set?
Good for another 40k miles......... 2012 TDV8 Vogue (L322)

I'm not going outside in the rain to look but I bought 4 of either Verde or Zero - either is fine as I'm not sure they are much different from each other although I did read somewhere on the internet (so its probably not true anyway) that Verde's are a bit lighter, have lower rolling resistance and are more suitable for summer use. Geoff

Verde's have higher rolling resistance according to the labels so probably the other way round? 2012 TDV8 Vogue (L322)

You see this is what I read and its apparently : You cant trust the Internet.

About the Pirelli Scorpion Verde

The Pirelli Scorpion Verde is an ultra-high performance summer tyre that was manufactured to be fitted to SUVs and 4x4s. This tyre was created using Pirelli’s latest materials, structures and tread patterns. The Pirelli Scorpion Verde guarantees drivers a more fuel-efficient performance and a comfortable driving experience in both wet and dry conditions.

This tyre is part of the Pirelli Green Performance range, designed with low rolling resistance alongside improved fuel consumption and lower CO2 emissions. The Pirelli Scorpion Verde meets the 2012 EU Regulation for reduction of noise which allows motorists to enjoy a smoother, quieter driving experience. Geoff

The Verde and Zero both have summer and All season variants. 2012 TDV8 Vogue (L322)

Either way it’s a personal choice, I even have the additional benefit of my own PNCS - “Personal Noise Cancelling System”, i.e. turning gradually more deaf with advancing years and only occasionally corner on 2 wheels, so price is the biggest factor, they are both good tyres in any case, whatever your rubber fetish. “If it ain’t broke, don’t fix it” -where’s the fun in that?

I dont get on with them but I bought my Michelin Pilot sport and Goodyear ultra grip from Costco who were a great price brand new stock and did the TPMS sensor for 15 quid each as part of the deal - might be worth a look know they stock both the Verdes and Zeros as tried them

I’ve just ordered a set of the NCS Zeros at Kwik Fit. There’s a decent offer on a set of 4 at the moment if anyone’s in the market.

edit: I don’t think Costco do Pirelli do they? I could only see Bridgestone and Michelins when I checked.
