I've had a set of Treadwright GuardDog 315/75/16's on my '05 chevy 2500hd for approx 1 year. They currently have approx 8k miles on them.
Waited about 10 full weeks from order to delivery.
They have molding imperfections that I was assured would not be an issue (and havn't been so far)
Within 6 weeks of having them mounted, there was a large balloon bulge about the size of a softball that appeared on my right front tire in the tread portion. Thank God it first appeared when I was stopped and picking my son up from school and not going 70 down the freeway.
(pics are on another computer)
Contacted them with pics of both the outside and inside of the tire and they replaced it at no charge to me, and I had the tire in hand within one week.
They ran fine, not louder than any other MT, nor any quieter.
I monitor my air pressures regularly and keep them and my overload bags on the rear axle all equal. The left rear has worn CONSIDERABLY worse than the rest, with zero reason other than poor construction. It's approx 1/4" more worn in the center of the tread than the other three (which are wearing GREAT IMHO).
It's a toss up. You get what you pay for. At $140 ea, they are considerably cheaper than new MT's of any flavor, but they are not without their issues.
I will not be purchasing another set because I value steering, braking, acceleration, towing, and above all the safety of my family and myself as well as others on the road.
I'm currently researching replacements and going to relegate the last 3 good ones to off road trailer and spare tire usage.
