When we first built the car, we had put 245/50/16's (25.7") on all 4 corners with the old wheels 16x8" with 5" BS. The fronts were so tight I never even attempted to drive it and went with 225/50's (24.7") on the front. I worked with Shawn at Newstalgia Wheel - we both agreed that 235/45/17's (25.3") were the "safe" size to go with considering we have the Eibach lowering springs up front. I needed to go safe because we were ordering the tires through the Continental Employee Purchase plan (our grandson works for them). If I had been purchasing through a local tire shop - I would have had them have both sizes in stock and tried the 245's (25.7") first. The 235's are .6" taller than the 225/50/16's and fill the wheel well nicely. Do I think that the extra .25" of BS on the new wheels might have worked to run the taller wider 245/45's? They very well may have with the extra .25" of BS on the Win Lites. But we're happy with the results - and the fact that the tires were only $370.00 including the shipping charges.
