thinking of looking for the G8GT 18" wheels and tires, have G8GT 19" wheels and summer tires with 600 miles, what would be price difference? anybody interested?, Im 90 miles north of NYC off NYS thruway.

Wish I was on your side of the country I'd gladly trade you my 18's and cash for your 19's.

nybob, why the switch to 18's???

want 18" GT wheels and tires because they are all season, I live in NY state and I dont want 2 sets.

want 18" GT wheels and tires because they are all season, I live in NY state and I dont want 2 sets.Shortly GM will offer 19" wheels with all-season tires which means that they will be more redily available to us with 19's in the near future (read before winter).

There are all seasons already in the 19" size, Tire Rack lists the following:

Performance All-Season (if there is such a beast)
Michelin Pilot Sport A/S

Grand Touring All-Season
Continental ContiProContact
Kumho Ecsta LX Platinum

Once the 09's come out or the GXP then you can see which ones GM thinks work best, or even a new version will come out, such as from Goodyear, like the 18's.

Don't give up on the 19's for snow just yet.
