I was reading through the GCR and I ran across a discrepancy.

9.1.3 Section 7 Wheels/Tires

In the first Paragraph 1. it states... "Cars may not fit wheel diameters smaller then those listed on their spec line. All other cars shall retain the wheel diameter fitted as original equipment for there make, model, and type. " but he GCR states in italics two lines down "Cars classified in ITR may utilize any wheel diameter up to 17" or retain their stock diameter wheels if larger."

The car I am building is a 2000 Celica GT-S it came with a 15 inch wheel from the factory but most of the cars were equipped with the optional 16 Inch wheels. The Spec line states a 16 inch wheel but according to the italicized ITR rule I can run any wheel as long as it is less then a 17. My question is can a run a 15 Inch wheel? It came with them from the factory and the ITR rules say I can run whatever wheel I want as long as it is not larger then a 17, but the spec line says 16, and the GCR says no wheels smaller then the spec line.

I don't want to order 15 inch wheels and tires only to find out they won't work in the class.
