I need more traction. My car is an 82` SC with a standard narrow body. My rear wheels are 17x9" HRE 540 series with Kumho esta cheapies. The hp is at least 375 to the wheels from a 965 engine in a 2500lbs car with close geared g50 from a 89` carrera.
The problem is that first gear is 100% useless(instant rev limiter and backfire) and second gear gives an pedal controlled tire spin. 3rd gear is the only gear I can keep my foot in it.
There are many brands to choose from but the 255/45/17 size is not available by most manufacturers. I dont think I stand a chance to fit 275`s under there so its either 255 or 245 for me.
I would really prefer to have a fairly stiff sidewall and run 18+ psi for street driving. I dont often go over 120mph but at those speeds I dont want crossing wind to shift the a$$ of the car around.
Im considering the Yokohama soft compound ADVAN A032R but im not sure if these are sticky enough.
I do not plan to road race this car at all so having a different front tire compound is no worry. I have other 911 cars for that. This car is for the sole purpose of straight line acceleration during daily use.
Im hoping someone here has found success with a particular tire and will pass on the info. I suppose a mention on what not to buy will help as well.
Should also mention that I always avoid driving in the rain and I am aware of the wet traction these tires have.

That car yearns to turn. Let it live it's dream.

This data is from about 5-7 years ago, but this was my breakdown of drag radials:

Nitto and BFG drag radials - stiffest sidewalls/weakest traction (these were for the guys with bigger than 15" rims who needed somewhat good cornering)

Mickey Thompson sportsman pros - cheapest priced/very good traction (the best all around for me)

M&H racemasters drag radials - best grip/higher priced than MT (friend had got a lot more traction with these over the others, a car with a tad over 900hp on the street)

Cant speak for Hoosiers or any other, this was my experience on the ones above. Like I said, this was from years ago and I do not know what is offered anymore, especially if you are looking for a stiff sidewall.

I ran Nitto's on my old car, hit 1.5X 60's. Running them on the Porsche now, but haven't had the damn thing out on em' yet. Couple mustang guys I know run them, hook 1.7's on stock susp. It depends how tall of a tire you can go with, I couldn't fit a 26" tall tire, and I have 17" rims for my drag radials. This severly limited the choice on what tires I could run.

If I could have, M&H all the way.

I think ytou will get enough traction by getting an ultra high performance tire instead of a drag radial. Falken Azenis 615s are available in that size and have fantastic traction and grip. Toyo ra-1s are a good choice as well.

I had BFG DR's on my Carrera at ~430rwhp. They gripped really well, even with a damp road surface, and even when they were very worn out with lots of miles on them. However, handling sucked, they floated around alot at highway speeds, and they overall did not feel very confidence inspiring. Just FYI, but I fit a 285/35/18 on 18x10's on the rear of my Carrera, so there is room back there on the narrowbody with the right offset. You could do a 265 on a 9" wheel, or even larger like a 275, however I think much over 265 and it will start to "balloon" outwards causing negative handling characteristics. As far as A032r's, from what I've seen they need to be warmed up to really grip well, and they don't sound like the best tire for what you are looking for. Try out something like a Falken Rt615 that's not quite an R compound but offers excellent grip. With any street tires, I'd pretty much expect to spin them at least a little bit in 2nd making over 300rwhp. That's just normal. When you are spinning all 4 in a 4wd car in 4th gear at 120mph, then you might have a problem. An acquaintence with an 850awhp Skyline has that problem.

I had 265's on the back of my 1984 model 3.2 carrera sport coupe.
