I think Continentals are largely an excellent brand. I have them as I said on one of my Golfs, my Vanagon, and my Sprinter. And I have a set of Generals on my F150. Both my Passats, and my other Golf, have Michelins. I prefer Michelins, but they also cost more.
You started the thread wanting input on Continentals, I only made mention of General because it is part of the same company (and not everyone realizes this...FWIW, BF Goodrich and Uniroyal are part of Michelin, Kelly+Springfield and Dunlop are all Goodyear, and Bridgestone/Firestone are the same company).
You provided the rim size in inches... so for instance (just guessing) a 195-65-15-91H is available in the Contiprocontact in the "standard" version, and the "eco focus" version. Both are the same 500 treadwear, both are AA-A traction rated. The Eco-focus version is about $12 more per tire. Will you save $48 worth of fuel over the ~50k mile expected tread life? Maybe, maybe not.
The Truecontact Touring, again same size, has the Eco+tech rating I mentioned in the above post, and has a whopping 800 treadwear, but drops to A-A traction. They cost less than the Contiprocontact in this size, they will last longer, might net a wee bit better fuel economy, and since they should also last longer, they should overall be a lower cost tire in the end, even if the fuel savings is minimal. However, they won't stick to the road as well. Will you notice this loss of grip? Maybe, maybe not.
17 inch stuff is FAR more varied, because now you are getting into a more performance oriented sizing. The 215-55-17-xxx gives you some Purecontact and Procontact and Extremecontact models, some of which carry neither the Eco-focus or Eco+tech banners, and will almost certainly provide worse fuel economy at the expense of stickier compounds and of course shorter tread life.
