I have CCD. No difference in mileage, ride is much better now, not sure if that’s from the size change or brand change. I attached a photo of the size difference. They are 3/4” taller and 3/4” wider. No rubbing at all. Much quieter on the road now too. I’ve ran defenders on 22’s for my last 4 suvs. I really like them. Great mileage warranty at 80,000 too. I have about 16,000 miles on these and they don’t look a day old.
