Bridgstone RE71R
So after trying the cup2's, 2 sets of dunlops, and the trofeo R on my GT4 i decided to try the new bridgstones RE71r. I have to say I am VERY impressed with this tire. It acts completely different from the other 3 tires. The grip is great and the wear on the tires seems to be better than the others. They seem to work much better mid-corner when you apply the power it grips much better and acceleration out of the turn is great. The first time i took them out on track i beat my best time by 1 second. It was confusing a i wasn't pushing very hard!! The tires seem to have made the car much more effortless to drive. Highly recommended. Oh and tire pressure hot at 35PSI as opposed to 30PSI hot for the others for optimum grip.

Also, if you wear out one side before the other (e.g., the left before the right), don't be afraid to just swap the wheels from the left to the right and vice versa. Running them backwards is fine on the track. I would assume it would not be a good idea in the wet, but I don't know from experience.

So for track duty you would rate them higher than Trofeos? I'm going to buy a new set after the next event and the RE71Rs are really interesting since they are cheaper and so far the feedback is very good....on the other hand the Trofeos also have good feedback in terms of grip. If you had to pick, which way would you go?....no Hoosiers please as I like to use my car on the street also and trying not to find an excuse to buy dedicated wheels/tires for 6 events per year.

Interesting. I found 32 - 33 psi to be the sweet spot for me. 35 psi seemed a bit greasy to me.

What about flipping the tires from inside to outside. The outer sides of my tires are at about 20% left, while the inner portion is at 80% tread left. I'm wondering if it's worth $50-$100 to have the tires remounted/balanced to get an extra track day/weekend out of them. Will these tires perform decently down to the cords? How long before they heat cycle out?

I agree re the pressures... 33 psi all around.

Anyway, for my driving, at Road Atlanta, on a 70 degree Sunday, they tested temps of inner, center and outer on all four tires over two different sessions.
They found temperature swings over 20 degrees from inner to outer. They suggested I drop PSI into the high 20s, like 28ish, and so I did. What they found was much more even temps across the tire surface. I'm assuming that this results in more even wear across the tire. My tires look great and my lap times got a little better, even late in the weekend.
This is track day 4 or 5 on this set...
Front right....
Left front always takes a beating at Road Atlanta, especially that outer edge.

Nice. Might list your alignment specs to go along with the temp derived hot pressures. Was rear the same pressures and temp?

I was also running at this PSI, and then there was a trackside tire monitoring "service" at my last event with Chin. They wanted $50 to test temps with a pyrometer, but I ended up getting a complimentary test over a couple of sessions. This was my first time experiencing this type of analysis.

when I get to 35 I pit and let air out to 30-31 (always happens first session of day as I start 26-28 depending on conditions)
running 35-36 too long kills the tire; I did it on a set and it really does damage of 2 track days in a single session. lesson learned
