Pontiac Solstice Forum - View Single Post - Factory Tires, Squealers?

All GXP's come standard with a "limited slip" differential.

This "limited slip"unit will at times force both rear wheels to the same speed resulting in chirping on low speed turns while under power.

As for "sticking to the road" thats a different matter:
You shouldn't be traction limited in dry curves unless there are insane speeds involved IMHO.
And yes I have tried these aforementioned insane speeds.... I know.
I am now limited by the nut behind the wheel...usually.
Of course it's another matter if you are "tracking" the car.

And yes there are better tires out there compared to the factory units.

Dunlop Sport Maxx"s gave me a perceived modest improvement over the stockers.
However I fully expect to see less tread life as the trade off for the extra traction.

FWIW I seem to have gotten the best performance from the stock Goodyears with 38 PSI front and 34 PSI rear...less understeer, close to neutral as in four wheel drift at the limit.
The same pressures are being tried on the Dunlop's.

Good Luck

Rickey.
