Help with tire choices?
Ok currently I'm running stock 18 size tires. Continental contisport contact p5. They do not grip at all from a dead stop. If I gas it too hard the back end wiggles and throttle gets cut. I'm getting dedicated summer wheels 19s. I'm looking for the best possible traction for straight line. No track use. I want the least limited wheel slip. I have stock lsd. I don't want an r compound either. Needs to work in the wet too. It's a daily vehicle. What are your opinions on best tires from what I'm wanting in a tire. Pss seem to have good reviews however Iv seen them compared to my current p5's and they are supposedly comparable?? The p5's suck for traction. depending on the tire id be looking at either a 265 or 275 rear. Thanks for the help guys.

Happy enough (F:245/35-19 R:275/30-19). The stiff outer specific sidewall makes for crisp turn in and nimbleness but prevents flipping them on the rims to extend life. First season rear grip was excellent, 2nd season they did tail off as the compound degraded with wear.
I re-purchased the rears for this coming season.

Michelin PSS hands down. I've run the other two on my Porsches and while their initial grip is excellent, they're noisier, drop off a lot sooner than the PSS (as in after one season - they heat cycle out and harden) at which time they also get a bit lairy in the wet. I run PSS on all my street cars now.
We use the AD08R on the ChumpCar as a dry tire, but again, unless you're going to change them every three months, don't care about noise and not drive them in the wet there are better choices.

Actually, no - quite the opposite. The PSS have a tendency to get a lot greasier on the track than either of the other two, but they fare better on the street in the long run. They (PSS) provide similar, almost-as-good (or better when worn or wet) grip levels on the road but are a lot quieter and last twice as long, but for track use, both the RE-11s and AD08Rs are better tires. Both are sticker than the PSS to begin with and don't get "greasy", but they will heat-cycle out and get hard 3x faster than he PSS. If you're going to wear them out in one season, great - both of them provide more grip than the PSS. If you use them as road tires, they will get quite hard and drop off after 4,000 km or so, so the PSS is a better overall tire for the street as you can get 12,000 km from a set and the grip levels would be more uniform throughout their life.
We use the AD08Rs on the ChumpCar as they are better in the wet (especially if partially worn) compared to the RE-11s, and in the 16" size we use, they weigh 3 lbs less per tire. It doesn't seem like much, but we're talking about unsprung weight here on a 2,100 lb car, and the fact that you can stay out instead of having to pit if it starts to rain is a pretty big bonus.

Do you know Frank Ewald by any chance?

We run a 225/50-16 square setup on the ChumpCar.
Re Frank Ewald - I dont know him personally but the name sounds familar. Does he drive on one of the other ChumpCar teams by any chance (maybe I've seen his name on the roster) or in SCCA Solo / CASC-OR?

Diabolis, do you have any experience with the RE-71R by any chance? I also did not like how the PSS behaved on track when hot, and am looking to replace this upcoming season with either the RE-11, RE-71R, or AD08R. I don't intend to drive like they will last beyond the summer. Thanks for your thoughts.
