I think you will be happy with the G003 tires. They are a very aggressive MT, and put about 200 miles on them today. Quiet for an MT, but def hear them vs stock and louder than Nitto RG I had on last truck. Interesting though you hear the hum more at 35-55 MPH but then at 70+ MPH they are somehow quieter it seems. So if you do a lot of highway miles, this is a great MT and ride well, better than Toyo MT and closer to a Duratracs IMO. No issues with the RC coilovers so far, ride is similar to stock I believe.
I have no doubt there will be better, more expensive lift options made for the Tremor in the future, but RC seems to get the job done and I’ll likely have a new truck in 24+/- months so I think it should hold up just fine.
