I got this set six weeks ago after much search and compare, I couldn't spend 2K on tires, and yet didn't want to compromise the characteristics of the Sports SUV with the hefty 5000 LB. My Q7 came in with the stock ContiPro H rated, worst tires ever 18K and got worn down to the bars with tire rotations at 5K Miles!! The long search yielded 3 tires that I considered very carefully.
1- The Firestone Destination with 40K Millage Warranty and 400 UTQG
2- The Hankook Ventus RH07 with 65K Millage Warranty and 420 UTQG
3- The Sumitomo HRT Sport with no Millage Warranty and 480 UTQG
I didn't get Firestones, as you end up having to deal with Firestone one way or another down the road, and my experience with the local shops was not good, zero customer service (even though the tire was very attractive see TireRack's test).
I didn't get The Hankook, as they become back ordered and they still are, even thought they had the best warranty in site and a nice tread pattern.
So I got the Summi's, even though the UTQG is higher than stock, so I was worried about the handling capabilities and stopping distance and the cornering ability for the 5K SUV. On day one it sprinkled and I was ready to exchange them right away, after I almost took a light pole at 25 MPH corner in the slick barely wet road!! However once the glossy materials got worn off, they performed much better than the Contis. I took them on a 700 Mile trip at highway speed and they stood their ground admirably.
1- Nice cushioning ride
2- Road noise was minimal, and better than the stock Contis
3- Very good handling, including slalom while avoiding crap on the road at hi speed
4- Great wet performance in heavy rain
5- I performed several straight line breaking tests including full stop from 60 MPH on an empty road, no problem and no squealing and very acceptable stopping distance.
That gave me back confidence with the Summis. Definitely recommended, they are no Michelin but they are superior
