Perfect
I take my 05 Explorer on light off road trails on weekends but I still need it to ride nice and smooth during the week. The Ridge Grapplers handle both like a champ! Grip is solid on dirt and gravel but they don't feel rough on the highway. road noise is way lower than I expected. very happy with them!

Surprising Traction and Handling Response for Dodge Charger R/T AWD. A New Customer for Nitto
Originally my car was running Goodyears just because they were a brand the family has been running (including myself) for years. But this past summer season was coming to an end and along with it a tire change. I was planning on going with the tried and true again until one friend mentioned I should try some different tire brands out to see how they compare. So I parked the car in the garage and started on my journey to research for the best tires that would fit my driving style. From Falken to Toyo, Continental to Michelin, I found any information on the companies that I could. Then I found out about Nitto Tires, a branch company of Toyo (independently running from Toyo). They got their foothold by going to competitors & attending car enthusiast and asking what they wanted from a tire. Through listening to the intended customers, they honed their tires to meet these expectations. So I decided to give them a try and I have to say it was an amazing decision. Right in the beginning i noticed that i didnt have as much slip as what I used to have from Goodyear. So I put another 1000 miles on the tires to see if there would be any fade in the grip. To my surprise, I didn't feel any initial drop off. I was able to take corners a little faster, the rear end didn't want to step out from behind as often, and no spinning the rear wheels on take off. In summary, if you are looking for a new tire brand to try out for you project car, muscle car, or any performance oriented daily driver, the best suggestion would be to try some Nitto's.

Perfect for daily & weekend warrior
Been running these for a couple months now and I get why everybody recommends them. Theyre quite comfortable on the highway. No hum like full mud tires but still grip well enough on muddy back roads. Sidewalls are tough no worrying about punctures. I've got 35s with a 3.5" lift on my F150, no rub, no trimming needed. CARID had the best price I found. Solid experience.

Grips well, quiet
They do everything well. Mud, rocks, snow - they grip. They're way quieter than my old MTs. Can still hear them a little, but for a tire this aggressive I can't complain a lot. They're not as rough as some other all terrains I've had. Thinking of buying again when these wear out.

Good Tires
Way better grip than the stock tires especially in the rain. Ride is smooth and they're not as loud as I expected for all-terrains. Capable when I take it on gravel roads and trails.

Awesome Hybrid Tire
Installed them on my 2024 Wrangler with a 2.5" lift, couldn't be happier! They look just like I expected them to and I love how they perform off road. Grip was fine even on loose terrain. On the road they ride well but do have a slight hum at highway speeds which is expected with a tire like this. Not a dealbreaker.

Best Mud Tire I've Owned!
I've run several different mud terrain tires on my 2012 Silverado 1500 Z71 but these are easily the best. Good traction, they grip in mud, loose dirt, and they don't feel sketchy on wet pavement. I expected them to be loud on the highway, but they're surprisingly quieter than other M/Ts I've had. Running them on 18x9 wheels with +12 offset.

CARiD Answer:
Hello, the tread depth for the sizes that will fit your Cadillac are listed as 12/32. As for the noise, there is no dB scale for tires. Noise will vary based on vehicle weight and road surface. Being an all-season highway tread however, these will be on the less-noisy side of tires.
