if you pay my insurance im sure its cheaper for me... if u do it that way

lol

Ha ha ha! To let you know why I'm keeping the tires as is, I have 18,000 miles with a ton of treadwear left. Do you see how I drive? The dealer said they hadn't seen a Z come in with tires in that great of shape after so many miles. I'd put the car at about 85% highway cruising.

But those stoplights on occasion, are killing me!

I hear ya, gotta live life a quarter mile at..........:wtf2:nevermind

Granny shifting... Not double-clutching like you should... You had me? You never had me. You never had your car. :rofl2:

:happydance: put 305's in the rear

The Bridgestones, as you've noted, are very temperature dependent. Having done about 6 track days on my original set, I've now felt the progression of not only decreasing tread depth but also aging rubber. The heat cycling has taken a toll on the tires, and I now understand why one would replace them even with tread remaining...they're just rubber bricks. Anything below 70F and the tires are like rocks with diminished grip. I notice it on a spirited corner and the back end comes loose. Then after some aggressive driving, the rubber gets much tackier and the grip improves dramatically. During my last track day, I could literally put my nail into the tire. One way to judge your tire temp is how the tires sound when you spin them. A cold tire gives a silent spin while a hot tire squeals like a stuck pig. At 18,000 mi, your rubber may have heat cycled enough that its lost its grip unless you really get them warm.

i drive mine city so mine are almost gone
