They do sing a little but I just installed a good radio last night so I dont mind. I do know that with brand new mud grip tires until they break in a little they seem a little loose on the highway. Like they want to float around. I'm pretty sure they will calm down and drive a lot better. But the best part is since i live in the country and it rained a little yesterday and today I drove straight through my driveway and out in the pasture and tried them out in 4x4 mode and wow I love em off road.

 

Those tires look pretty serious and beefy. They have a real mud terrain look to them kinda like TSL Super Swampers. I like them kind of tires. Now I have to save up about $1300 for new mudders for my Ford. Adding a 4" lift and going from 38.5" to either 40" or 42" TSL Boggers. Not sure on the size yet, need lift first.

 

My 82 k5 blazer has the rough country 4 inch lift and 3 inch body lift with 37inch boggers. But it is just about only raced in the mud drags. It very seldom see's trail riding. I do have another k5 that I am planning to build up as soon as I come up with a tranny for it. I aquired a set of brand new 44inch tractor turf tires on 20 inch wheel. The tread depth is about an inch and a half and I plan to cut every other tread out to make them more like super swampers. Its already got a 4 inch susp. lift and I will build another 3 inch body lift for but I have a pretty good idea already that I will have to do some serious fender trimming to make em work.
