I've got nothing but good things to say about mine...had them for 6 months and 5K miles now through all types of driving. So far they are wearing like iron, no loss in grip, and turn-in is as crisp as ever. I run mine at 34psi(F)/32psi(R).

Thanks, I will up the pressure a bit and see.
I was at around 32.5- 33 cold, but it was really freekin hot here lately.

Lance, I have the same size ES100's on the 968 and AVS in the same size on the TurboS and have been pretty pleased with both. As others have stated here, try running higher pressures - I run them at 35/36 cold and they are fine.

The AVS are a lot softer / stickier and on track, I can definitely tell how grippy the AVS are catching IanM's car in the corners while he gets away on the straights with all that extra HP. The ES100's may have less grip and not as progressive as the AVS, but for the street, I find them pretty decent all round - esp in the wet.

32/36 on mine...now that were talking about tire pressure :-p

That could be just the drivers

Thanks Randy I will try upping the pressure.

Of course your grip sucks when they are new! Kinda surprised nobody mentioned it yet, but you really can't judge a tire after 100 miles. In fact it usually takes around 500 miles of driving until the mold release is gone from the tires. Give it 500 miles, if it still sucks then take it back.

grip is not the issue, turn in response is slow and mushy, like driving on Krispy Kreme donuts
I dont think time will change the sidewall stiffness.

I'm happy with my ES100's on street and track.

BTW factory spec is 36psi front/rear on a 89 951.

Put air in. I noticed a difference when I put my crap tires up to 36 PSI all around (I was aiming for better mileage for my long trip). They were at 32 before. I suggest 34. At 36 I notice mine track the road a lot more, the steering is a lot more "mind of its own" now.

Note my tires arent ES100s... They are "Zexius"

I love my es100s same size. They drive like crape with under 36psi all around though.

From the pressures everyone else runs I wonder if my 215-60/15 is the reason mine seem fine at lower pressures than a 17" I also run 35/36psi on my Turbo (Kumho's) with 255-40/17 & 215-45/17. It must be a sidewall thing for the taller tire.

K27

You are absolutely right, I upped them to 36 all round and it was a marked improvement.
Never had a tire that pressure sensative.
Much better now, but I still feel they squirm a little more than I would like.
I dont want to go too high and have them wear down the center.

KuHL 951

If you can get 255's to wear in the center, I'll buy drinks for the house!

K27

Right then, my compressor goes to 110psi, I'll have a Bud please.

You got me! Hope you have a small house.
