Re: Wheels for snow tires
MOPAR has an 18" steel wheel for the GC
Quick Google search shows they run about $150 per wheel.
Seems like the best bet since you would be sure it would fit properly, though you can buy cheap aluminum wheels for that much...
You would need 265/60R18 tires to keep the speedo accurate.
18" is the OEM size for the Laredo X and Off Road package.
