I'm not due for new tires for a while, but I would rather plan ahead than wait till mine wear out. I am looking at these two tires for my next set. They are both thin, LRR, and roughly the same diameter. The Continental tires come on SmartCars, and the Potenza's on the Insight. Now I do know that the RE92 is the king of fuel economy. However, the Continentals are 20mm thinner for better aero, so they might be a competitor to the RE92s. I do not mind getting new rims for the Continentals. I will get 15x4 spacesaver wheels for them if they are decided on.

So, what says you?
