Treadwright Tires Houston,TX Treadwright Tires Will not honor warranty Houston Texas

Purchased (4) 245/75/16E load range Warden A/T II s with premium wear and extended warranty for additional 49.96$ on 05/14/18,tires arrived on 5/18/18 and I had them professionally installed by GMC dealer, 3 out of the 4 tires took a lot weight to balance them because they were out of round,4th tire needed 83 lbs of road force to balance,and it called for 18 ounces of weight to balance,theTire tech deemed 4th non useable do to huge hump present in the tread area that made it severely out of round,i called Treadwright Tires,they shipped out a new tire, tire was installed, it took more weight than what they normally see, but it was on our with the three I had already. I was on interstate running 72mph when I felt a major sudden vibration, I immediately pulled off on the next exit,

the right rear had a huge bulge in the center of the tread, so a blow out was imminent,i put my spare on called Treadwright, dad online chat & emailed them, finally was able to get someone on the phone, they said send in a picture, I sent them a picture showing the flawed tired, there email response was that it wasn't under warranty. The truck it was installed on is a 2500 series avalanche with 73,000 miles. I previously had bfg ko2 on it and they were flawless.smooth till tread was gone, towed 30,000 miles. So now I have 0 confidence in these tires. I logged a complaint with the BBB of greater Houston,TX and with the Attorney General of NC (purchased online shipped to NC). My opinion,skip Treadwright and go with the (((REDACTED)))s, pay more and feel confident the tire will deliver as promised.
