I had a set about 5 years ago in their old school mud tire tread. Did NOT enjoy their customer service at the time and went through quite a hassle over a tread seperation after less than 400 miles and 2 days of use. Got a new tire and all seemed well for most of the next year when I started to notice the tread pulling off the carcass on the sides of two tires. A call to them resulted in me being told I could NOT get that same tire anymore (despite their site listing it and yes, it still does today). I ended up just giving up on High Tec and was about to buy new tires when my ex wife rolled the vehicle. I let the tires go with the SUV. Didn't want to hassle with them anymore.
All that said, that was 4-5 years ago and under High Tec's banner. I also know that several of the employees I dealt with are no longer there and one lady was actually fired for being rude to customers. I hope that under the new banner they are better than I and a few others were treated but we seemed to be the anomaly even then.
I've seen their stuff now and would consider it. I'm hesitant but hope they are better now than during my experience. The price of new tires now is so insane.
That said, check Ebay and the like. After the ex rolled her SUV I shopped around for a similar size tire for her new SUV (was the same make) and found a set of brand new Kumho MT's on Ebay for about the same price delivered.
One piece of advice, get the Green Diamond crystals or whatever they call it now. Little crystals of stuff that get embedded in the tread as they make it. Act like studs. I **** you not those tires, even being muds of an old school design, were some of the best winter tires I've ever owned. We buzzed through drifts and snow, ran over ice, and all sorts of other stuff that a Northern Michigan winter threw at us with little trouble.
