My manual shows a 8.5 x 19 55mm et by 11.5 x 19 67mm et. Does any body make this size in 18 in. diameter? Plus can I get Rival S 335 x 30 18 under my 07 NB with a 11 or the 11.5 in. wheel. And will a Rival 275 x 35 x 18 front fit.

 

When looking for wheels, I find Tire Rack a great resource. (Be sure to try searching for a few other vehicles that share the same bolt pattern as yours does; for example, I found wheels for my BMW M3 that were only listed for a 330i, and wheels for my C5 Corvette that were only listed for a C6.) Failing that, Google and eBay are also good places to search -- just enter your wheel width, diameter, and bolt pattern and see what turns up.

 

I think that is the size that the GT3 cars are running. Since they are running Rival's and the GT3 comes with 19 in. wheel. Since Rival doesn't make anything larger than a 18.
