Is that 5db estimate based on an actual db meter reading, or your personal audio estimate?Same - went from K02s to a ridge Grapplers and dropped about 5db in Road noise. Seem much smoother and quiet but they are new compared to K02s. Love the Grappler look. Much more aggressive. Off-road performance has been great too.
Thanks for the db info. Yes, miles on the tires makes a bit difference in noise.I used dB Meter app, same road and similar speed, mounted to dash. I got 75 dba with K02s (40k miles) and dropped to 70 dba with Nitto Ridge Grapplers (new). It’s unfair to say it’s apples to apples. I am tracking over time to see how they hold up. I posted earlier to simply say I feel the Nittos are smoother and look so much better on the truck from how I remember the K02s.
Initially they are more quiet - time will tell. I am very happy with them. I run K02s on my jeep and had to replace one this week - Costco was unable to get the tire. It turned into a huge hassle. I won’t buy from Costco again, and it appears BFG may not be manufacturing???
