I have the General Grabber 275/55r20 XL on my truck now. I like them,good ride,fairly quiet. I haven't had them on long enough to comment on tire life. I have 2 winters on my General Grabber Arctic and I will get another winter 5 months out of them so roughly 30000 miles. The General is made in USA
My dealer has been happy with them. I've had Toyo summer and winter tires. Winter tires were fantastic but only could get 2 seasons out of them. Summer tires last a long time but they are very hard. I also had Kuhmo summer and winter tires and I wouldn't recommend them. Not a bad tire but they don't last . The factory Good Year that came with the truck were a pretty good all around tire I got a little over 60000 miles out of them.
