anyone running Cup's yet?

Yes it's a 'feel thing', but you can also tell by the touch (if stationary) - just put your hand on them, they feel like chewing gum!
But beware.......... the slip angles......... sudden breakaway and you have to be quick to catch.

Sounds good.

IIRC, Elliot said on Mtorque its difficult to get them to temp on public roads?

[derek]

i agree with that you probably end up with less grip on the road especially in scotland, ps2 work better on road

[SMD]

Cups will be fine! After a few miles have some fun!

They are fine on the road and despite other comments, you can generate adequate temps on road. Just adapt and change your driving style. You can feel the grip levels build very easily once you get to know them.

Just one word of caution. When they're brand new they are VERY slippy slidey. They need a scrub in. On track be very cautious for 2-3 laps, as Mark found out in his post.

Sounds good thanks for the info Alex!

[SpineOnABap]

Yeah as Alex says you can get to "adequate" temps on the road, enough to still be miles ahead of the PS2, but you'll never get to the levels you can on track.

[AlexGTT]

Agreed Elliot, they are in their element on track and to be honest, if I drove my CSL every day, all through winter, I'd probably run PS2's and save the Cups for Summer only.

On your favourite, deserted, roller coaster A/B road (we've got loads in Wales ) you can work up decent temps to outperform pretty much any other road tyre. I usually stick in 26-27 psi cold, check temps half way through my run and they've levelled nicely at around 31-32psi which feels just right.

On track you'll find yourself dropping the pressures quite considerably as you build up speed and temp, usually way lower than 26psi cold, especially if the ambient temps are high. So remember to put some pressure back in when they've cooled down for the drive home.

so 26-27 psi in cups for road use?

If you plan on pushing up the pace and depending on road conditions. I'd say find what works best for you. Mine only comes out for fun and this works well for me (maybe I should write a disclaimer here )

I've seen so many Cups worn out because they are over inflated. They'll go in no time with 33psi cold in them, that's for sure. Unless you drive like Miss Daisey.
