Anyone running this tire which I would get the 275/60/20. Was wondering if you have lost any MPG since they are a little on the heavy side for an SL tire at 49 lbs. Wondering if they are quite on the highway like the Hankook AT2's I have to replace? Last do they wander on the highway at all? Thank you

 

I have been running the Sumitomo AT (P275/65/18) for 30k miles now. It's been a good tire and my only real complaint is the weight and high rolling resistance. I did loose about 1.5 mpg with these tires comparing to the OEM Goodyears. Slightly more road noise comparing to the Goodyear HT's which is not bad at all and track very well on the highway.
