Deciding to go with the Continental ProContact EcoPlus+ tires and going up one size from OEM. 600 A B
They rate pretty well in these tests...
Eco-Friendly All-Season Tires — How Does Performance Measure Up?
Also I have a sub to ConsumerReports and this tire is the second best rated tire in the
all season touring category. RollResist is rated as excellent.
Assuming a LRR tire does 5% better than the avg tire as far as mpg...over the life of the tires...they could pay for themselves...maybe at least partially.
* turns out they don't have this tire in the size I need...still a good tire though
