That's what's in my GC with the 'full size spare' that comes with the factory tow package.
Though I didn't check if there was any extra room between the tire and the lid.
That's the only tire that TireRack has in that size.
Yikes! Shipping from TireRack is $80.
You can pick one up at your local PepBoys for $200.
Found this if you want to stay close to the OEM 30.5 inch diameter:
30" Tire Diameter
175/90R18 = 30.4X6.9R18
235/65R18 = 30x9.3R18
245/65R18 = 30.5x9.7R18
255/60R18 = 30x10R18
265/60R18 = 30.5x10.4R18
285/55R18 = 30.3x11.2R18
