Not sure how many are still visiting here as once before, but since I received no reply from the "Ask a Question" entry from AM site, figured I would try here...

I'm looking to get another set of 315/35/17's for my FR500 17x10.5's and currently am running Sumi's which have really done well and since I drive about 100miles a day thats really important to me along with traction and all the other criteria that can fall into play when choosing tires.

I wasn't sure how the Nitto 555R's tread-were holds up compared to Sumi's, see I have had these Sumi's for about 1.5yr now and have had no complaints out of them what so ever. I don't ever see the track, so not really concerned with there take off and stickiness as reported by many. More concerned with how the rubber compound is between the Nitto's to the Sumi's and don't mind paying a little more for the tire's if they are going to give me the same longevity as I have experience with the Sumi's. and heck if they were a little quieter wouldn't hurt any either, so some reason I get a good bit of road noise from them, but could also be since the tread is wearing down some too. ( Nothing a little turn up of the tunes doesn't cure ).

So if anyone can pipe in and give me your thoughts on this, looking to make a decision very soon.
