Ride quality is great, better than stock tires IMO and noise is virtually non existent. They are an E rated tire which is nice if you are going to be towing. They are a tad heavier and I feel it some, but I have 3.55 gears and it isn't really that much difference. Mileage has dropped some with the most noticeable being in town with all the stop and going. I'm getting between 12-13 mpg in town but haven't been on the interstate much but I'm doing 1000 miles next Friday so I can PM you if you are interested.

currently cant change the speedo as they dont make tuners for the 2011's yet. But from whtat i can gather there will be a 4% difference in the speedo slower. so 50kph is actually 52kph. So until diablo comes out with the latest tuner, my speedo will be off a bit.
