I would consider the test loops to be normal driving conditions for
central west Texas only. All of the test routes are rural and San
Angelo is a small town. Rural roads in Texas are usually in superb
condition without potholes and are essentially flat with long sweeping
curves. Its easy to go 100+ mph for long distances. The bad part of
the test loops is the summer temperature. 115F air temp in the shade at
5' above grade in the summer and 150+F on the roadway. I used to live
and work in the area.
There is no comparison to Houston's bumper to bumper traffic with
corresponding slamming on the brakes, making sharp turns, and running
over road debris. If the test loops predict 50k miles usage from a tire
then I'd probably half that for Houston, or 25k miles. However, the
test loops would be good for a comparison / ratio between tires instead
of using for a discrete number.
