I have 36. 0" Parnelli Jones Dirt Grips on my truck. Recently the truck was getting a little squirley on the road and kind of hopping in the rear. I put the truck on jack stands, started it up, put it in 4 wheel drive and transmission in drive. I was shocked what I saw. The left rear tire is about 1 inch out of round. Went back to where I bought them to complain. These tires have only 17,000 miles on them. He measures my tire tread depth which measures 10/32". A new Dirt Grip measures 21/32" tread depth. Shop calls the distributor, who states that the tires are only warranteed for out of roundness for the first 9/32" of tread wear. So for 2/32" they will not warranty this. So now my $320. 00 tire with half tread wear is useless. I'm fuming. Still waiting to hear from Dirt Grip. I e-mailed them nicely with my concerns. Now I'm forced to buy a new tire. So buyer beware. I thought I finally found a quality big tire, NOT!!!! I was very pleased with these tires up to this point. Oh well, I'm done venting. I guess that old adage applies, if you want to play, you gotta pay. -Glen
