Guys, looking for a new set of rear tyres - 265 or 275/35R18 inch on a 9.5 inch wide rim. Budget around $500 each.
What street tyres are going to give me full traction in 1st gear in the dry? Or am I going to have to go semi slick? I'm running hankook K104s and can't even get full traction in 3rd in the dry
I have a set of Goodyear eagle F1 GSD3s on the front which seem great... - but wouldn't have any idea how they do acceleration wise.... ideas?

At 250rwkw, full race slicks are still going to spin at full throttle in 1st gear, there is no way of avoiding it!
If you're willing to spend that kind of cash (why?) then I'd be looking at a Pirelli P-Zero Rosso, the Michelin equivalent, or possibly even a Yokahama semi-race tyre. Only problem is that with that power (assuming that you like to 'utilise' the power) you'd be luck to get 15,000km out of them.
So you're not going to get full traction no matter what tyre you use, so in my opinion, you'd be better off spending that cash on 2 sets of reasonable tyres, instead of 1 set that still won't fulfill your requirements.

Chris, I am willing to lay money down that there is something else to do with the loss of traction in 3rd gear (if its in the straight line). Presuming you have overdone coilovers or an unevenly matched spring/shock combo causing the dramas, no tyre is going to get traction easily.
If you were being money critical, a good dry road-tyre like the Federal R595 RS is a great option if they make them in a 265/275/285. Planet Soarer - MOTOR Tyre Comparison
For more expensive semi-slick options, Bridgestone Potenza RE050's are your best bet for track like handling, and i'd suggest the Falken Azenis RT215 as a cheaper alternative thats more daily driving friendly due to stiff sidewalls.
Another thing to consider is camber and worn bushes, get a wheel alignment done and ask them to make it even at all costs, not 'as close to spec as possible'. If you have an aftermarket swaybar and overly-stiff suspension, its usually disastrous in terms of power oversteer and a handicap no matter what tyres you decide to use.

Ok, clarifications about what's happening. It's manual gear ratios I'm talking about and 3rd gear loss of traction is not severe - it's usually accelerating onto the freeway on ramp at 90km/hr - it's barely noticeable - I can live with it
The reason I think it's the tyres - is that when the tyres are cold, I get bugger all traction. But when they've got a lot of heat into them (say after driving for 30mins) - there's only a lot less wheelspin - and a lot more acceleration
My suspension mods - Torsen diff stock, Tein HAs and whiteline sway bars. I've got my rears set on 7 clicks from softest. I've tried the softest setting on the rears, but it barely makes any difference to traction (although it makes a big difference to ride comfort!)
Camber is set on -1 degree both sides, toe in .5-1mm (i think)- tyre wear is very even

If you like the Goodyears on the front, try some on the back. They grip very well and price tends to be reasonable for such a good quality tyre. I agree with several of the other suggestions as well. The Michelin equivalent of the P Zero Rosso is the Pilot Sport II. It is the best current street tyre at the highest price. I class the Pilot Sport Cup as semi-street or something like that, but it is certainly better in the dry. It wears a lot faster the the PS 2.

I'm using Falken Azenis RT215 semi slicks, in size 255/40/17. Work pretty good with a torsen. Depending on the road, it can grip in 1st if its good road, if its bad road, it'll spin thru 2nd. They cost me $290 each in that size.

I got quotes for Michelin Pilot Preceda 2 in the size of 275/30/19 (rears) at $670 each (OMG OMG!). I'd hate to see how much more the Pilot Sports 2 would be
