I've had these on my truck now for about a year and a half still have 16/32 on them. i drive alot on the highway cause of work and have gone through a foot of snow in 2wd to see how they work and they are great. only time i have to use 4wd is when the wife is with me. I take my truck up in the mountians on my weeks off work fishing hunting and camping. been in deep mud and never had a problem going anywhere i would buy an other set when these are done.
