Poorly made, craptastic unbalanceable tires
These tires have been a headache from the start. Part of it is my fault. I should have checked the reviews of the installer before I chose them (Firestone, Garner NC). The shop never balanced them so the driving vibrations could make your butt go numb. It took contacting the regional manager of Firestone to get the issue fixed at a different location because that Firestone took it upon themselves to break other components on my car (long story). When that shop went to balance the tires, they discovered that the road force was so high on 2 of the tires that they were unbalanceable. Now I have had to replace my rear shocks because the back end of my car bounces down the road. When replacing the shocks, it was discovered that there is a bulge in the sidewall of the inside of the right rear tire which is the one with the highest road force. Basically I was sent 2 "OK" tires and 2 craptastic tires that ultimately cost me much more. I messaged simpletire with no response. I've been a customer of simpletire for years for multiple vehicles. I hope they get on the ball and fix this.
