Iv got about a thousand miles on the Nitto NT555s now and am super impressed with the traction from them. rolling at 5mph in 1st and floor it and theirs minimal wheel spin, bang 2nd and it chirps and goes. a vast improvement. As far as wet weather traction i cant report much because my truck usually doesnt get driven if it rains. But last week my daily was off the road for a few days so I had to drive the truck and the one day it rained. only got on it once or twice and wet traction was very good as well.
