The oil advice part of this forum is great, but I am surprised why there is no similar forum on tyres. Surely manufacturers initial recommendations are not always the best option, given how tyres develop so quickly...

Anyone know which winter tyres are best for a 2013 Cayenne Diesel S by the way...?

You'll get 100 different answers if you ask anything about tyres!

I suspect because tyres change quite regularly, even if only for cosmetic/marketing reasons. Most people when asked will only recommend what they are using, whether it is 'good' or 'bad' in reality. You might change the oil every 6 months, but tyres you would hope last a good bit longer - people's requirements in terms of journey type and trade off between dry grip/wet grip/life/noise/price all make it virtually impossible to give a straightforward answer.

Ref Cayenne, will depend on wheel size but Dunlop Winter 3D seem to get good reviews wink

You're best off on a porsche forum. Better yet a Cayenne forum.

Even so, prepare for conflicting opinions and internet hearsay presented as cast iron fact.

Tyre wise I'd just go with the correct load and speed rating for your vehicle, work out which offerings from the major tyre manufacturers offer best value somewhere like opneo/mytyres/etc and then research the specific tyre.

That's what I did and ended up with some Nokian WR3s to replace the Vredstein Wintracs that were on it before. Both good tyres BTW but neither as good as Michelin Alpins or Bridgestone Blizzaks which I'd previously used.

There is no subjectivity with oil. Oil has only 1 function. To keep the internal moving parts of your engine, moving. Just use what the manufacturer says you should use.

Tyres, there's bucket loads of subjectivity. One man's ditch finder is another man's track day weapon.

What is it with internet hand holding these days? Can't anyone make a purchase without an electronic committee?

Just buy the best you can afford and be done with it, or here's a radical idea, why not ask a Porsche dealer what tyres to put on a Porsche?

That's funny because some people will pay ££££ for Super Magnatec Enduro Fully Synth (or something like that) and some people swear any old oil will do provided you change it often enough, some will swear you must use low sulphate oils, gear oil you have to figure out if you can't put GL5 in or if you need GL4 to avoid eroding yellow metal synchros but the official oil in the manual is no longer made and there's no mention of whether the replacement is GL4 or GL5 and hardly any oils even state if they are but you don't want to need a gearbox rebuild do you?
Then there's the debate as to whether rotary engines and/or Subaru engines are better off on mineral rather than fully synth never mind the fact that there is or was a loophole on whether an oil can be described as fully synth despite not being fully synth.
Oils are complicated to!
Oil has one function, keeping your engine (and gear box) sliding instead of rubbing.
Tyres have only one function, keeping your car and the road rubbing not sliding.

Basic answer on tyres is you get what you pay for, buy expensive and other than that go by description, if they tell you it's an extreme summer performance tyre, it might not do too good in winter, if it says it's for winter, it's for winter.

Failing that, just get AD08s as they're the best tyres ever yes
(actually they're summer tyres and they do suffer a little in cold (subjectively) but will still be better than Ling Long winter tyres wink)

I believe the standard PH answer is if you get cheap tyres your car will explode at the first sight of a drop of water or a bend. Twice.

Be a wee bit carefull with your selection.

Porsche have their own ratings for tyres (certainly the case with the coupes) If you trade your car in, a Porsche center will not want to retail the car with non Porsche spec tyres and will knock the PX price accordingly.

Oh the joys of working an Dunlop aye

Tyres do no end of things rather than stop the underside from dragging the floor. The deformation of a tyre based on vrs things such as its corded structure , the type be it cords or wire plus the bias and amount and then wall thickness plus vrs other things means certain tyres work better than others if your after say smoothness of ride . Bung tread on top of that and it becomes impossible to simply say what is or isnt best on a car . There is personal preference and thats without every other consideration ( dont mention after market rims ,,,, just dont ) . So simply put its best to aim to ask what individuals think of what they have fitted to their own cars and yep a thread would be a good place to find out info

There are specs for oils - API / ACEA / Manufacturers. So there is at least a right answer (or normally, several).

But apart from tyre size and speed rating, there isn't any spec for tyres as long as they're legal

That is a piss take...

Similar to apple using non standard device connectors and charging £30 for a new USB cable. Considering it's a Porsche; (this next argument applies even more to the coupes that tend to have more petrolhead type owners) it's more likely to have had an owner who's not going to put ling long ditch finders on it.

All new tyres sold in the EU now have to have an EU tyre lable:
http://en.wikipedia.org/wiki/Tyre_label

Most tyres also have a UTQG rating on the sidewall:

And there's a really rather useful site which collects the tyre tests published by different magazines:

Plenty of info is available to make an informed decision on what's right for you - HTH

I wouldn't mind the 'what oil' thread if people with modified or unusual engined cars asked the questions...but it's mainly people who have a boring off the shelf rep-mobile like a BMW 320i (but they seem to think is special because it's 'mildly modified' by adding a magic tree air freshener), and who clearly can't read the owners manual to find the answer to their dumb retarded question.

...can you imagine how bad a 'what tyre' thread would be?

TyreReviews is my site, and I try and help in every thread I see.

I'm always happy to answer any questions. I did suggest to PH we have a tyre sticky like we have a oil sticky in which I would be happy to try and help where I can, however the money involved made it a none-starter. PH are commercial afterall.

There will always be someone with better advice than me, as unfortunately I've not been able to test every car / tyre combination on the market. What I can offer though, is a fairly good overview, after reading around 20,000 user reviews, every thread I can find, every test available, and I've been part of testing at plenty of tyre tests myself.
