The front rims would have to be the same as the back, wouldn't they?< Erik - Not a good idea. The tire size, along with the rest of the suspension package was designed and developed by the best suspension people in the business - Lotus Engineering. The tires were sized to give predictable handling given the weight distribution of the car, the roll center, and the polar moment of inertia. The results are quite good. Changing the size of the tires on the front of the car to match the size on the rear will tend to bias the handling from mild understeer (which is what you want) to oversteer - the back end of the car will tend to come around at the worst possible moments like braking in a turn, lifting in a turn or anything else that would unweight the rear of the car. You could potentially have problems with brake bias as well. The same behaviour would occur if you tried to make the rear tires the same size as the front. The front end of the car, already high to begin with will be even higher throwing off airflow and headlamp aim, plus you will probably have some interference between the tires and the front bodywork. Properly sized Yokohama AVS Intermediate tires are available from places like the Tire Rack for well under $100 per wheel shipped and installed. There really isn't any reason to tamper with the tire formulas until correctly sized tires are no longer available.
