Michelin & Big O

When I put mine on I was going for the fact that there are Big O dealers most everywhere here in the west and I was using my truck alot for business at that time and wanted to have service available if needed.
I was going to use Michelins but have been told that service is sometimes hard to come by in some remote areas.
I've never had problems with a Michelin LTX that needed repair or replacement (other than wearing them out), in any area. Since my first set of Michelins in 1973, I have had exactly four flats over 30 years and all on passenger car models. I've found that if you are in an area so remote that you can't get a Michelin fixed, you can't get anything fixed. Keep in mind that most (maybe all) Big O stores sell Michelin tires. I suspect that they make more money on the house brands, though. Michelin isn't a high markup line.
There is a serious problem with heat buildup in the southwestern states. The Arizona Dept. of General Services settled with Firestone over those ghastly Wilderness AT tires several years before the news broke nationwide. The settlement agreement requred that the State not issue a press release. Meanwhile, more people were killed.
Some brands of tires are better able to handle the heat than others. Generally speaking, tires made in segmented moulds are much better than those made in clamshell moulds. How do you tell the difference? Several mould lines cross the tread on a tire made in a segmented mould. There is a single circumferential mould line down the center of a clamshell-moulded tire.
However, in cooler country, most tires seem to do very well. A colleague in northern Idaho has gotten 60K miles out of a set of Goodrich tires that often separate at 20K here. Similarly, another colleague just north of Butte, Montana routinely gets 50K mile and up out of Goodyear Workhorse tires, and whatever variety of Toyo is popular there. Here, they are bad news. One of my OEM Goodyear Wrangler AT tires went 50 (yes, fifty) whole miles before it separated.
It's true that any tire (even a Michelin) will separate if it is not maintained correctly, overloaded, or properly inflated. The 80 PSI maximum inflation for a Load Range E tire is based on 70 degrees F. When it's 100 degrees F outside, the pressure needed to carry the same weight is closer to 90 PSI. Bleeding off air from a hot tire can kill.
