I changed from the Firestone Transforce to the Nexens because of the heavier sidewall than the Transforce. The tire store I do business with recommended them over the Firestone Transforce as their truck fleet tire. Of course the next tine I have to get tires they may have a tire they recommend that I have to make a decision on. Since they have a large customer base in our area with many repeat customers and trucking company contracts I take their recommendations and make a decision. I originally had Michelins but the sidewalls had scary sidewall cracks after 3 years. I liked the Firestone Transforce better than the Michelins for handling. I have no issues so far with the Nexens. The run of tires I have had installed is solid so far.
