i have had terra grapplers since november 2002 and put about 8000 miles on them. they look like they have minimal wear.it really looks like no wear but that is impossible.i get compliments on them all the time.i saw an ad on the back of a magazine,nitto is going to be making a mud tire that looks awesome.i checked there website and they have not listed it yet.that will be my next tire for sure. shawn
