The trail grapplers are loud, and pretty rough. They aren't much better than mud grapplers IMO. (I actually like mud grapplers, but they are loud) I wouldn't even consider them. 99% of people that have them get them because they saw them in a magazine, or on some company truck, or because they are new or whatever the hype is. It happens every time. Even with wheels, think about all the rockstars in the late 2000s. On every truck in the world. And tire wise, trail grapplers and those federal M/Ts (which I can assure you are terrible riding too) are both trending.
Anyways.... Toyo M/T is the quietest and best riding m/t you can find. They were super popular around the time of the rockstar wheels too, but kind of fallen off now because they are so old. People like new styles but there is a reason toyo has been so successful for the past decade with their M/T.
The trail grappler is patterned a lot like the BFG KM1 and the Goodyear MTR, ever had experience with either of those after about 10k miles? Good luck. Ive owned Boggers and TSLs that rode better.
Point of this, I wouldn't buy the trail grapplers. And as suggested, stay with a D range tire for the best ride.
one last though, **** cepek Fun country 2.... friend of mine had them, great tire. sold a few sets too. Everyone seems to like them, they do have a slightly louder than average hum for an all terrain I would say but its not bad.
