This was in sharp relief to at least one of the tires tested that actually went ~ .98G dry, but ranked waaaay down on the wet (to something like .5G).

I had the first hand experience with some tires on a rental car that gave it up on a wet curve WAY before those "D3s" did on an equally wet surface. Just sayin.

I'm thinking if I never did another drag race, I might be more skewed toward the GY "D3s". But, as pointed out, GM is/was putting P2s on the Corvette says "something" about those tires. (I'd like to get the chance to drive on some one day and see how they compare to the Nittos on dry and especially on the wet. Something tells me I'll prolly like them better ESPECIALLY ON THE WET [NO CONTEST there]).

Some of the Battlefield Corvette Club members (Fredericksburg Va.) are going to be at Dominion Raceway this Sat. to introduce the track to people who have not been there. I plan to go and gather info and insights.

Neat tip about tire psi while sitting.



Thanks to all for taking the time to answer!

Don’t get too confident, if the temps dip below 50 degrees or more, Summer tires are terrible. What you can do speed wise in Summer are not there in cold weather. I wiped out twice at VIR in cold weather on GS-C’s. Changed to Michelin, but expect the same “in the weeds” experience if I go there later this month.

Many places are not dreams but nightmares. After doing this for 39 years, have seen the good, the bad and the ugly.=D>

I replaced the hard, dry rotted/flat spotted sumitomos on my car with the nittos when I bought it. I couldn't justify the Goodyears for the insanely high price compared to the nitto's (I'm going to burn through these tires pretty quick with the way I drive the beast.) Wet weather performance on the Nitto G2's is exceptional. I drove the car 4 hours in a moderate to heavy downpour and they performed flawlessly. Very predictable at their limits in the wet. No flat spots to speak of (yet, we'll see after the car sits all winter.) Dry performance is good but the sidewalls seem a bit soft so I run 40psi all around (drop the rears if you want more bite for standing starts obviously.) Dry track performance I'd rate 7 out of 10 for a street tire, but I'm not an experienced racer.

Paul,
My thoughts on wet driving; during a heavy downpour my 335’s will hydroplane above 50mph making my cars fishtail.

[lfalzarano]

No tire can standup to deep standing water on roadways above 50 mph. GY GSC’s provide excellent performance in wet and dry. I’ve been using the on my Z got over 18 years, BUT I recently switched to the PS2’s. My current experience in the dry they are superior to the GY’s. The ride is smoother and quieter than the GSC’s. I don’t drive in the rain anymore, but I would venture above 50 mph. ZR-1 tires are just too wide not to aqua plane above that speed. Real world experience! JMHO
