Bit early to be pissed duncan :hahaha:

Its NEVER too early for that mate !

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

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

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:.

ideally left overnight first :smokin:

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

Cheers guys :beer:

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.

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_csl]

Fook off Duncan! :bigcry: :bigcry: :bigcry:

Good enough for me Shim :smokin:
