Default Nitto 555G2 Long Term Testing

Nitto 555G2 Summer UHP review. 500 mile report.

I was lucky enough to be selected to test the new Nitto 555G2 Summer Ultra High Performance tires.

I received the tires and installed them April 29, 2016 and have put just over 500 miles on them now. The size is 255-45x18, just a little different from the stock 235-50x18 and the small difference in size has little effect on the speedometer. The extra width of the tire though looks great from the back of the car!

These are at least as quiet on the road as my Nitto Motivo were. That set has 7/32 or 8/32 of tread so that set may have a little more road noise. The ride is very smooth. First thing I noticed, the car handles like it is on rails. Definitely better handling than before. Dodging potholes, or having to make a quick turn, the car moves right away.

I had a chance to try them in the rain and grip was still very good. Hit the accelerator getting on the highway and firm, crisp, shifts with no noticeable tire spinning.

So far I am very pleased with this set of tires. During the next review period I hope to get a chance to try them out at the drag strip to see how they do on a pass there.

Update on my Nitto 555G2 tire test. I received the tires and installed them April 29, 2016 and no have just over 5,000 miles on them. I found that in order to get a better MPH on my car I needed to adjust the tire revolution per mile higher than the online sites were saying. Finally found the correct setting so that in 20 miles of driving my odometer is off by 0.2.

Now that summer is here and I am driving with the top down frequently I have noticed that the 555G2 has a little more noise than the Motivo that I was running previously. With the top up, about the same, but top down I can hear them more. Nothing annoying, just was looking for the difference as part of my review.

I had a chance to try them at the drag strip. Not as grippy as my drag radials, a little more than the Motivo or the stock Pirelli Pzero that the car came with. My impression is that they are more of a road course/street tire than a drag strip/street tire. The grip in cornering is still noticeable after 5,000 miles.

So how did these hold up while you still had the car? Anyone else using these on their car?

They were great. I am thinking of getting them for the 2017 EcoBoost because I liked them and living in North Carolina I don't really need to worry about having to swap to the snow tires in November.
