Also remember that when talking only rolling resistance in same tire size effect to fuel consumption is only max 7-8% better fuel consumption between best and worst. Now you can easily make calculations is it worth to buy brand tires or not. Based on Finnish tire magasize tests usually it is as brand tires tend to last up to twice the miles longer.

I would not fully trush the wear ratings or what you think Capriracer is there some legislation that manufacturers cannot lie on that rating?

If you open the door to changing size totally different the bigger diameter (longer distance travelled) and aerodynamics (narrow) effect more than the LRR compound.

I would go for 175/80R14 if you can find a good set (if your state laws allow them). In finland you can find over 35 manufactuers for that size so there must be some importers to US also... At least in Finland you can buy used set easily 50-100$ so you can test their effect. If they dont work sell them and buy different size.
