Here's what I'm noticing after a few hundred miles.
Aside from efficiency, the ride quality is about as good as you're going to get with AT tires if you get the SL load rated version.
- Trips between 5-10 miles with stop and go traffic: Efficiency is significantly less than the stock dunlop PT22 all season tires at ~15-16mpg. My city is at the foothills of a medium sized mountain range, so my local driving is mostly going up and down hills. The stock tires were doing around 17-18mpg locally.
- Trips over 20 miles w/ highway driving: Efficiency is almost as good as the stock tires at ~20mpg.
