Tyre comparison.

[rstoughy]

I need a comparison on 888's and Cups.

Got my prices for both and they come in at around the same so no issues there.
However Cups have very little tread depth compared to the 888's so my main concern is that they wont last any time at all.

So i need a comparison on,

Wear rates of both tyres?
Performance of both tyres?
If anyone has ran both and can give me non biased reply that would be good.

Thanks,

There's plenty of threads on here asking a similar question Paul. The general consensus is that 888's don't cope too well with the M3's weight & don't fare well.

If both 888's & Cups are of similar price, I know which ones I will be buying! ;)

BTW, I've only got experience of Cups...

Sorry i cant help at all,the only experience i have had with cups are double fs;):whistle:

R888 in 19 inch have only been available in CSL sizes for a year do not many have run both

the Porsche guys however have found that R888 have a shorter track life before going off, even as few as 3 hot laps, which means first you get less value out of the day and second the R888 are more likely to get cokes and be ruined

I would try Corsa Race or Dunlop Direzza before R888

I ran R888s last year as I have run them on other things before, the Porsches run R888s and are a fraction lighter than us.! although I'm 100+ kg lighter this year, so may be better. I have found them a great tyre, better than the PS2 on road and track in the dry of course, but I have run the Medium compound and do seem to go off a little early on UK circuits, but heat up nice & quick too IMO. A great fast road tyre/ good track tyre. Should be fine for the Ring IMO. I find they wear very well on road and track. May be worth trying harder compound but think that has been tried on here before and discovered they're no better. Toyo prices have also gone up this year like all, so around £700+ a set.
I would go the Dunlop Dz03 £1200+ route but prices are stupid this year, so opted for 18" PS Cups @ £900, after all they were designed for the car! ;)

Brilliant thanks guys :thumbs:

The 888's are actually coming in @ £28 more than the Cups :shock:

Guess that's it decided then. Cups it has to be :thumbs:

I have 2 confirmed track days / weekends this year, Croft in June and the Ring in Aug so hopefully they last :bigcry: :bigcry: :bigcry: as also an Insp 2 due before the ring :banghead:

[shimmy]

one recommendation is to get the Cups heat cycled either by you on the car OR by a specialist. It will add life to the tyres:thumbs:

Cups every time... no doubt about it...got to be the way to go .... no doubt in my mind... not that I have ever driven on any of course ! ...but I have read the threads !:hahaha:
Slightly worn PuSsy'2s in the warm at the Ring last week end after about 3 laps were giving me understeer, and werent turning in ...whatever T$ comes back and says !!
I may need to buy a full set in the Fatherland sometime this/next week, as I shall need them for the big TD there on the 19th April, unless your gearbox isnt done T$ ! THEN WE COULD SWAP THEM OFF YOUR MORTAR :thumbs:.. bollox, and I wasnt doing too bad with caps..or is it Cups until then ...ass !

Please explain more on this Shim? :bigcry: ;)

Bit early to be pissed duncan :hahaha:

Run them up to temp, so they have a full heat cycle in them before you go on track hard with them, like running them in for example, it helps prolong the wear, and keeps them in tip top shape ;)

Defo cups got bloody 888 on the gayman at the mo sounds like the wheelbearing have gone:bigcry:

[shimmy]

Please explain more on this Shim? :bigcry: ;)

as Daz says a heat cycle will bring them up to temp for a period and help to change the nature and format of the rubber which prolongs the life. Basically it sops you shagging them first time out.

The best way to do it si to pay someone (Like Track Club) £10 a tyre and it takes them a couple of hours on the machine that looks like a sun bed.

Other way is to give them a good run out BUT NOT TRACK SPEED and then rest them overnight. So a trip on new rubber to Spa or the Ring, then parking overnight before hitting the tarmac is pretty much perfect

HEre is a better explaination from Tyre Rack:

The first time a competition tire is used is the most important. During that run, its tread compound is stretched, some of the weaker bonds between the rubber molecules will be broken (which generates some of the heat). If the tires are initially run too hard or too long, some of the stronger bonds will also be broken which will reduces the tire's grip and wear qualities. Running new tires through an easy heat cycle first, and allowing them to relax allows the rubber bonds to relink in a more uniform manner than they were originally manufactured. It actually makes them more consistent in strength and more resistant to losing their strength the next time they are used. An important heat cycling step is that after being brought up to temperature, the tires require a minimum of 24 to 48 hours to relax and reform the bonds between their rubber molecules.
Looking at the heat cycling system, it positions a mounted and inflated tire between rollers which apply pressure while the tire is rolled up to speed. It is very important to note that this allows heat to be generated as a result of deflecting (stretching) the tire within its normal operating range. There is no "artificial" heat added (no oven, no forced air, etc). Then they receive the stamp showing they are Tire Rack heat cycled.


Bit early to be pissed duncan :hahaha:


:hahaha::hahaha::hahaha: although it is never TOO early tbh

[rstoughy]

Good stuff,

So basically if i fit them here in aberdeen and drive the 3-4hrs to croft (sensibly) then they should be ok?

Could always take them for a spin out Royal Deeside B roads and heat cycle them that way.

ideally left overnight first :smokin:

Its NEVER too early for that mate !

[DuncanR]

Bugger, I could do with a set of Cups , 19" being done for next week at the Ring TD.... any ideas ?:banghead: i dont have the tyres as yet ! Would need to sort it out early next week in time to ship them out tut Ring for next Saturday.
Free beer to best answer...even if not the cheapest solution!
I would work it all out myself but i simply have to make myself a toasted anchovy sandwich for lunch !:smt055

Yeh they do that John, when you first hit the track you will think your diff is fooked too, the noise is quite bad. :banghead:.

Easy peasy, drive down on the Fri, Track on the Sat :thumbs: :thumbs: :thumbs:

Cheers guys :beer:

Cheers Shim, I assume that the ones I've got off you are pretty much good to go!? :thumbs:

Good to go Dan ?? from the tread they have already gone mate !! :hahaha:

[shimmy]

If they are used they are heat cycled Dan

the ones you have got have already seen a lap or two :)

[Dan]

Fook off Duncan! :bigcry: :bigcry: :bigcry: ;)

Good enough for me Shim :smokin:
