I just had a set measuring 255/55/18 V mounted on a set of black 18"x8.5" Voxx Maglias a couple weeks ago on a 2010 Mazda cx 7 turbo. I really like how they grip in dry conditions over the original tires it came with, especially under "spirited" acceleration from a dead stop or on a roll. The old 235/60/18s would spin under the same acceleration. In my opinion they handle very well in wet rainy conditions as well. They handle water puddles very well. The Mazda's handling has improve a bit in the turns, probably due to the increased tire width by approximately one inch on all four corners. This tire is also more comfortable, again due in part to the extra cushion the 255s are offering over the 235s from before. I do not notice any increased noise from these tires at all. Overall, I would recommend these to someone else with a Mazda cx 7.
