IMHO 'ME AGAIN' has the best answer above. The Michelin XPS all-steel cord tire is undoubtedly the best commercial tire on the market. That tire has been around at least 15 years and I have yet to see or hear of a single complaint (some complain about the initial price, but ................)
I was in the tire industry for 40 years, did many scrap tire analysis, and questioning of persons who had tire failures. Most is classified in this order:
- cheap tires to begin with, or tires too small or low load-rated.
- poor maintenance of air pressure.
- overloading, usually having no idea what their rig really weighs loaded.
- Impact damage, i.e., hitting something in the road, holding your breath for a
few miles, then breathing again 'because I didn't ruin a tire'. Well, guess
what, you really did, sometimes it takes a few hundred miles to actually blow.
- failure to have tires inspected by a qualified tire technician beginning in
their 5th or 6th year.
- Lastly, tire age. Don't be snowed into thinking tires will self-destruct
after 5 or 6 years. Properly maintained, they should last a good 10 years.
Could be more reasons, but these are the ones that come to mind; in that order.
