Tires

[G8GT4now]

My PS2 tires only lasted about 11,000 miles on my V

So far, I have 15,000 on my Continental Extreme DW with plenty of tread left.

Is there any accuracy to concerns about negatively affecting PTM, if one switched from the OEM Good Year spec... To a similar high end competitor?
Fbod Father? What wo
uld GM engineers have to say?

Love the G/Y's but would gladly trade off a little higher end, hot, track tackiness for better ride, quieter, wet traction, street use. More wear would be a bonus. Cost is not first consideration.
The Michelins seem to be the leading contender?

Glad you posted about your contis. I put these on my Z this past Monday. We now have 3 - 4 inches of snow so it may be awhile before I can really drive them but am super pleased at the mileage you are getting.

Good Luck

You'll need a lot of luck finding this tire since Bridgestone doesn't make it.

onlinetires.com has the G:2's for $310 fronts, $340 rears. They actually just increased price, I bought mine one month ago for $290 fronts and $320 rears and that was before applying the $80 Goodyear rebate.

[ZL1-V]

I ended up at America's Tire at $378 a piece for rears.

ItI have 5800 on mine right now and they look very goodstill. Only one autocross and the rest highway. I think they last longer in cooler climates. As i got it in october they have only seen 80 degees the weekend i was in scottsdale. Probably 6 to 8 32/nds left. I am thinking 12000. Seems accurate. About once a year for me.

[joes407]

i got 20k out of my first set of goodyears the Zl-1 came with. that was no track days and they were so bald i didnt dare put them on wet road.

[SlingShot]

For me I plan on going with Hankook V12. I don't track my car, only street and they are great on my SS.

[KKreme15]

8,000 aaaaaaandd they're bald.
Time for some new ones!

[joes407]

all of them or just the rears?
