Hi help required ,
There is a guy quite local with a set off pilot3 225/40/18 ZR 92Y XL are these ok for a GTI or are they the runflat variant TIA
-
Will be perfectly fine for the GTi, my PS3s are marked up exactly the same :happy2:
-
Pilot Sport 3 are not run flats.
They are perfect for a GTi.
I have them on my vRS (Same Engine) and they are by far THE best tyre i've ever had and i've tried most of the performance ones.
Dry grip is at least as good as the rest if not better. But wet grip they come in to there own and are leagues ahead of any of the others.
I found road noise was reduced and i have even got a slight increase of around 1-2mpg with round town driving. M'Way mpg is still the same.

Beddie how do you find 1st gear grip in the dry with the PS3?

I've never noticed any issues tbh Rich, suppose that speaks volumes for how good they are at getting on with the job of getting the power down with no fuss :happy2:
Best tyres ive had on the '30 so far and strangely the cheapest if you get them via Costco when the 20% offer is on!
-
Right.... in that case im sold! My falken 452s (crap, rubbish, tat [insert your own]) dont like 230bhp never mind 300!! :sad1:
-
Anyone know if they can be got in 19"?
Thanks
-
i buried my right foot in 1st up a hill earlier in the damp and nothing but pure traction :smiley: best all round tyre goin!
-
Not trying to cause debate on my tyres here or anything but I've just fitted some contacts sport 3s and they are amazing, they have won 4 out of 5 tyre tests this year too.
Worth a shout if you can get a good buy !
-
Hope you are all sitting down - but I'm finding the PS3s a tad disappointing in the wet - or to be precise, in standing water. They aquaplane in standing water much more than the PS2s
-
Which is why I'm surprised when you stated this last weekend, T_T. Everyone else has positive reviews.
In theory, given enough water, wouldn't all tyres suited to the Golf aquaplane?

I have found the exact opposite today.
Been rainining heavily here and was out today in the vRS. Went through a couple of patches of standing water in a couple of dips and the car kept straight and true through it. Mind you I wasn't going too quickly (circa 40mph in a NSL) which may have helped.
-
PS3 are way better in the wet than PS2's IMHO :happy2:
-
Where is the best place to buy PS3's, price-wise?
Nearly finished the conti's that came on mine from new (which have been quite good actually) and would be keen on trying the PS3's having heard so many positive reviews on them.
-
If you have a Costco card the 17's are £117 ish fitted and sometimes they take 20% off :party: Not sure on the 18's prices but probably not that far away.
-
PS3 are way better in the wet than PS2's IMHO :happy2:
Exactly my findings too :happy2:
-
Great tyres thanks to people on here, the grip is really good & is great in the rain today as found out today givin it some after getting stage 2+ lol
-
Peeps keep going on about Costco. What's involved there then?
-
So . . . all you who are claiming the PS3s are better than the PS2s - exactly how are you coming to that opinion?
I have two cars - one with brand spanking new PS2s, and the other with virtually new PS3s - and I can assure you - the PS2s have a far better resistance to aquaplaning. All on identical roads (I have a geeky standard test route for all my cars, loaners, customers, etc.)
The PS3 is generally better in some areas compared to the PS2 - but the PS2 is noticeably better in the wet - particularly in standing water.
-
But your comparision is based on two different cars T_T?
Personally I fully agree with michelin's own comparision:-

This is based on running PS2 and PS3's on the same car :happy2:
-
^^^^ Your the only person I have heard say that Sean.
Every review I have read and my own experience say different and agree that PS3 are better especially in the wet than any of the other popular performance tyres (PS2, Sessantas, F1 Assymetric etc)
Maybe it's your driving :P :evilgrin:
-

And your comparison is based on what? Brand new PS3s replacing worn out PS2s? Most brand new tyres, even shyte ones, will perform better in the wet when compared to old tyres on the tread wear indicators.
But yes - they are on two different cars - but then those cars have tyres matched to their overall abilities. The GTI comes standard with 225s (and I upgraded to 235s), and my RS4 was standard with 255s (now upgraded to 275s). The new PS3s are on the GTI, and the new PS2s are on the RS4. The other important issue is that the wider the tyre, the more prone they are to aquaplaning - so my monster 275 PS2 boots on my RS4 should be far more prone to aquaplaning compared to the narrower 235 PS3s on the GTI - but the opposite is occuring.
I initially thought it might have been a dodgy batch of PS3s, and advised my local ATS (who I generally use, and who are owned by Michelin). ATS initially advised me they also never heard of any aquaplaning issues. I'm now on my second set of PS3s (different batches - I'm rather anal about checking and recording batch codes - I do the same with my oils) and they are exactly the same - and ATS are now confirming they are getting a few others who've advised them of similar aquaplaning issues - in standing water.
Personally I fully agree with michelin's own comparision:-

Marketing and statistics. Just remember what Mark Twain said! :wink:
And do you have a link to the specific data? I'd be interested in how deep the water was on their 'wet' tests.
Oh, and just for some balance - I don't agree with that diagram for dry handling and dry braking - I would personally state that the PS3 is noticeably better than the PS2 in those two measurements.

Maybe . . . maybe I'm unconciously aiming for puddles and standing water. But then I'd be doing the same on the PS2-shod charriot! :sad1:
I think the crucial issue of 'dispute' is the degree of wetness - on normally wet roads, ie, wet but well-drained with no standing water - I don't have any concerns. It is only with standing water, such as puddles at edges of roads - where the PS3s are worse.

To be fair both 2 or 3 s are amazing tyres

^^^^ - yes, now that I do agree with! :driver:

The RS4 would has much weight to force the tyres through the water and on to the tarmac in comparison to the golf. this would surely help?? but saying that they are wide tyres as well.....

My GTI kerb weight = 1454kg, tyre load index 95 (for the 235s) - which makes an individual tyre max load of 690kg, giving a total tyre/vehicle capacity of 2760kg (roughly 1.85 times the kerb weight).
My RS4 kerb weight = 1755kg, tyre load index 100 (for the 275s) - which makes an individual tyre max load of 800kg, giving a total tyre/vehicle capacity of 3200kg (again, roughly 1.85 times the kerb weight).
So like I touched on earlier - the tyres are fairly balanced between the two in terms of vehicle weight vs tyre spec. And this would still prove my opinion that the wider tyres on the RS4 will be more prone to aquaplaning. Unless there are any other geeky formulae or calculations. . . .

Surely the Quattro helps :confused:

EDITED for correct spelling - quattro is spelt with a lower case 'q'. :P
Not really, quattro only really helps with traction. If/when a tyre aquaplanes - it won't make any difference weather said wheel is driven or not.
-
Yes i know how Quattro ( :P ) works and also what Aquaplaning is.
The point im trying to make is thus…
The correct way to deal with aquaplaning is to hold the steering straight, don't brake or apply power, just lift your foot off the power and let the car gradually slow down until you have cleared the hazard or you are at a sufficient enough speed for tyres to effectively deal with removal of the water.
Therefore as your front wheels hit the water first (Unless your doing your own impression of Tokyo Drift) then maybe the car detects this and reduces the power to the front wheels and maintains it at the rear thus helping the car's stability and your impression of the tyre ability.
To quote Audi themselves
quattro continually adjusts to road conditions to permanently distribute power between the front and rear wheels precisely where and when required. It means the vehicle stays responsive even if only one axle has enough grip.
For you to conduct a true comparison you are going to have to have 2 sets of wheels with 2 sets of equal tread depth PS2 & PS3 and try them on the same car. Which is how any tyre test is done. You don't see EVO doing there annual tyre test on 2 different cars and then saying a tyre on a 4WD/AWD car is better than a different brand on a FWD car in the wet :confused: :P
-
But you do see EVO blatantly biasing their tyre tests!
-
Im not saying they don't. Most "Tests" like that in these magazines are biased in some way. Depends who is providing the biggest sponsorship that year :laugh:
The point i'm making is you are comparing FWD with a clever 4WD system that monitors the grip levels many hundreds of times a second and has 4 wheels to direct power to on 2 Axle's rather than 2 wheels on the same axle.
Hardly a fair comparison :smiley:

When did I say I had aquaplaning under hard acceleration? I didn't! It was at a fairly constant speed, with a very light throttle. So traction doesn't come into play - and nor does the specific type of drivetrain. Period. So there is no point trying to confuse traction with aquaplaning.
Secondly, the Torsen based quattro is purely an analogue system, and apportions the torque bias infinitely, steplessly, automatically, and purely mechanically. It is vastly different to say a Haldex based system which relies totally on electronics.
The ONLY time it becomes unfair comparing front wheel drive with four wheel drive is under hard accleration. Cruising at constant speed, or braking - the playing field is leveled, and neither has any distinct advantage.
-
Utter rubbish. How does a free rotating axle and a driven axle compare :confused: wether your accelerating hard or not if you are driving at a constant speed then you are providing power to that axle and therefore if the TCS detects the front wheels losing grip then it will compensate at the rear. On a GTi it has no power at the rear so nothing to push it through the standing water.
However I never once mentioned acceleration so stop trying to twist my post to make yourself correct. I also never once said what I was saying was gospel and correct. I was pointing out that 4WD is better in the wet (wether aquaplaning or wet traction) and that MAY have an effect on how the car deals with the standing water. The traction control system in your RS4 is a lot more advanced than in a FWD GTi and you don't have to be driving hard for it to work. If you don't believe me go and feather your throttle on ice and watch the light have a disco on your dash.
As I and others have found (apart from you) PS3 are better than PS2 in the wet. I even stated that I had been through standing water in my vRS and found the car held straight and true and didn't aqua plane. The only difference between my vRS tyres and your GTi tyres is the cross section. Mine are 225 and yours are 235. Now maybe the difference is your extra 10mm width makes your car more susceptible to aquaplaning. But I doubt it.
As I said and I maintain. You cant compare 4WD against FWD. Whilst I haven't gone from PS2 to PS3 I know people who have and they have a different opinion of the tyre to you.
No one is saying you are wrong as that is your opinion based on your experiences. What people (myself) included are pointing out is that it could be other factors apart from the tyres.
-
Carl - I think you are on your own with your thoughts on drivetrain. I respectfully suggest you study some professional vehicle dynamics subjects - taught by professional and university qualified engineers.
Traction does NOT induce aquaplaning - although I accept that excessive and agressive traction will aggravate aquaplaning. You need to speak to Michelin technical, (or any of the other tyre companies).
Aquaplaning is simply caused by the inability of the tread of the tyre to clear the water from the road surface. Front wheel drive, rear wheel drive, four wheel drive, six wheel drive - they all have no effect.
And - you are also confusing aquaplaning with loss of traction - again, the two are very different.
-
I suggest we just agree to disagree. As your obviously not understanding my point. Either because I'm not making it clear or your just interpretting it a different way.

i hear custom code remaps stop aquaplaning....
