The blindingly obvious answer (or rather, question) is, what are you changing from and what do you want from new tyres? i.e. more comfort, less weight, more protection.

Did'nt you understand my post. What size continental gp4000

I'm in the camp of not understanding your question - the clarifications requested (and highlighted by Ugo in his response) make complete sense.
Incidentally I run 23mm on my 303FC - 25's don't fit my bike!

I'll try and explain, I'm purchasing a pair of Zipp 303 carbon clincher's, what size of continental grad prix 4000sII tyre's would give the best performance.
23 will be marginally more aerodynamic, 25 will have better rolling resistance if you are heavy. Both effects are very marginal and can be counteracted by eating one extra raisin in your porridge

At last, thank's Ugo. What length valve's would I need for the 303's

The 303 are 45 mm deep, so 60 is the very minimum... I'd probably get a longer one though

I stick a 40mm extender on a 38mm valve so 80mm all in is fine.
According to Zipp, 23mm front and 25mm rear is the best combination for aerodynamics and reduced rolling resistance - http://www.zipp.com/support/faq/faq.php

We're on tubs btw.

Bro, no one understands your post.
