Winter tyres


ORIGINAL: grover

Thnx I was thinking the 18" with Dunlops from Porsche at c£1700 would do the job, summer ones are 21"

Fitted these on mine - seem absolutely fine. Nice to have the higher sidewalls now too; feels like a proper off roader (well at least I can go up the kerb now!) [8|][;)]

 
I've 20" for summer and 18" with Michelin Alpin tyres for winter. They are very good in snow and these are into their 4th winter. I went for the smallest rim size to get the deepest sidewall, more to do with preventing rim damage than looks. They are a comfier ride than the 20" wheels and with the state of the roads up here just now the extra sidewall is always welcome.
 
On 18s the comfort is so much better and with a tyre like Dunlop winter sports it will look like a proper off reader too,the grip in wintry conditions including snow is unreal,the packages you can get from Porsche centres are competitive too,I bought ours from Leicester.
 
I found the all season snow and mud tyres pretty good all year - front outside edges did start going at about 16k miles though from hard cornering with 2.2 tonnes...
 
Having done 4 years of winter driving over the alps and mostly the Jura in my S petrol there is
only one choice 18 inch wheels with Pirelli Scorpion Ice and Snow mid european spec not uk if you can get them .
You may be able to get Euro spec from My Tyres

I am interested in which rim size and preferred tyre brand people choose for winter tyres, I thought I would get a set for my 2014 Cayenne deisel, platinum model.

Ive been using Michelin Latitudes on an old set of 18" rims for the last couple of years , only thing I' m concerned about is that the incoming 2015 diesel has TPM as standard, so the winter wheels will need to have the correct valves or the dash will light up like another Christmas tree! Does yours have this system fitted?
 
In October 2013 I decided that winter tyres would be a sensible purchase for my Cayenne Turbo. Finding winter tyres for the existing 21 inch rims was impossible.

Having researched a number of Porsche documents and tyre reviews, my preference was for Pirelli Scorpion and Ice, as recommended by Porsche, and I knew I needed to buy a second set of smaller rims.

Although Porsche UK were unable to supply any rims with Pirelli Scorpion, my local dealer located a set fitted to a new car in the showroom.

I had them fitted last winter, whilst the dealership stored my summer rims. Now into my second winter, and there is no comparison.
They provide a much more re assuring grip. Sadly they don't defy all laws of nature, and black ice is still a problem.
 
I have now fitted the 18" wheel and new Dunlop winter tyre as the standard approved package for the 2014 model, bought though as a new set via Jasmin PorscheLink
saving money off the OPC package price

Summer alloys and tyres in garage until sun comes out again.

They look a bit puny compared with the 21" rims but handles ok

I bought 4 brand new Porsche Kn 18 inch wheels with the tyres for £400 on Ebay
Had to drive from Kent to Brum to collect them.My old wheels are on the car
car now fitted with the Scorpions.
It seems that a lot of people order a new car and change their wheels when they
get it ? Look on Ebay when searching for wheels. I did the same with my
Freelander .

I did the same and picked up a set on ebay in the summer.

Also running Scorpions [:)]
 
Hi

I put my winter wheels on late October (Standard Porsche 18" Dunlop Winter Tyres), we had a freak fall of snow here in Northern Ireland , West Coast Derry/Londonderry on Tuesday night , now i Mean about 300mm in places. This thing will go anywhere on these tyres absolutely brilliant.
 
I purchased a set of 18" refurbed porsche wheels off eBay for 400 and a set of Pirelli Scorpion winter tyres for under 600. These are something else. I was driving through snow in the Alps this year and we got through deep snow and ice tracks where other snow tyres needed chains. The cayenne gets a lot of looks in the Alps. We felt like film stars!

I just acquired a 2009 4.8S came with 22in rims. Just got a set of genuine refurbished sport techno 20in rims with winter tyres on ebay. Not much difference in ride quality, the air suspension makes a tremendous difference there even the 22 are OK in comfort mode on quite bad surfaces, but the 20in are quieter than the 22in. Debating whether to keep the 22in for summer use or stick with 20in all round, have heard the 22in are prone to damage.

Anyone had any problems with damage (other than kerbing) to 22in ?

Got some auto socks for a trip to the alps at easter as chains seem to be a major headache for wheels bigger than 19in and hopefully the auto socks (which are recognised as an alternative to chains in France now) will be sufficient at Easster time when serious snow fall less likely. Anyone used auto socks?

Unless the rules have changed in the last 3 years not all cars have to have chains
in Frog and Switzo. 4 wheel drive and Scorpions were deemed sufficient on my Kn
A Defender was also ok on their normal chunky tyres .
 
Don't know about Switzerland Austria etc but the rules have if anything been relaxed in France since 2010 to allow Auto sock type textile traction devices as an alternate to chains. Prior to that if the B26 Snow chain signs were on in the alps the Gendermarie wouldn't let you carry on if you didn't have chains to fit. see http://www.roofbox.co.uk/car-snow-socks/AutoSock_France.pdf

It seems like you've already made your decision.

I've got a 2011 Cayenne Turbo with winter rims and tyres. They are Scorpion 'ice and snow' tyres.

With 4x4 and winter tyres, no car will defy the laws of physics, but winter tyres are noticeably better on wet roads, and pouring rain.

I have winter tyres on my RS6, which I believe are a Dunlop brand, and again, excellent.

I think they are FAR from a big con.

I have to agree with Condor .. As I expected issues due to the "quattro" not being a true 4wd system I ran winter tyres on my C6 RS6 and never had any issues getting out of the garage in any weather (including the Jan 2013 snow) and up a 200yd 15degree ish "cul-de-sac" (so no snow clearing by council) up to to the main road, on my last Cayenne S Hybrid (958) I did not bother as we had a number of mild winters here in Hampshire/Berkshire and I hoped its more formal 4WD system would be ok -until we had a fair snow drop in Mar 2018 and could not even get the Cayenne (I admit it was on 21inch tyres) out the garage (RS6 was on 20 inch tyres and was a good few kilos lighter than a Cayenne). I now have the Gen 3 (Model 9Y0) Cayenne Hybrid (again on 21 inch tyres) . so again monitor the long range weather forecast re snow / bad weather and consider do I get a spare set of rims with "winters" on
 
Not a con ... on ice and snow they significantly improve traction and reduce braking distances, which can affect most places - all depends on one`s perception of risk. Have been using them for the last seventeen years, sometimes all year round without issue - some last as long as Summer tyres

(Muddy / slippery byways are not their design brief)

gdavison ... our Touareg also runs 21" rims and required fresh tyres recently. After consulting the `very long range` forecast I opted for a highly rated `wet` Summer tyre from Nokian. Many Summer tyres have better wet ratings than most Winters.

 
Winter tyres in the uk are a tad iffy. They are designed for temps sub 8 degs and really start working a few degs below that. The old winter tyres were basically tractor tyres designed to churn through snow and worked best in narrow widths. the modern tyres are quite different they are much softer than normal tyres and have slits called sips carved into the tyres designed to grip ice. Abuse them by running the pressure too high or running them in warmer temps and they will quickly degrade. They are also much less effective once the tread drops to 4mm indeed in some countries this is the min tread depth which is sometimes marked in the tyre. I normally do 3-5k in the alps every winter and get 4 years out of a set before they drop to under 5mm but i do very little milage in the uk on them. They do shift standing water much better but on a dry or damp road surface at above 2-3 degs your braking distance can be 25% greater. The following will give you some idea.

the current crop of winter tyres are staggeringly capable I haven't used snow chains for more than 10years in the alp and my drive there is a 25-30deg slope up normally covered in snow and or ice And the ski station car parks are often an ice rink. Thee is no way i would drive a heavy suv in those conditions on anything but winter tyres. Tye germans will fine if you get stuck while not using winters and switzerland and austria will deem you at fault in any accident regardless. The garages in switzerland are full of english suvs who think 4 wheel drive is a good substitute.
in the highlands yes but in England unless you are going skiing in the alps then i suspect you would be much better off using all season tyres in the winter.
 
I appreciate that in the wilds of Guildford winter tyres may not make much of a difference
Some areas of the UK do get snow, sleet and frost and as I live in one of these areas I can confirm that snow tyres and all season tyres DO make a difference. sometimes a dramatic difference
So I would advise keeping your ill informed comments to yourself for fear someone takes them seriously
Cayenne and 996
