Disagree with you 100% on that. I've been driving on wide singles for 8 years with ZERO problems in rain and snow.They suck in the snow and even heavy rain!
For a guy like you Mike that picks his own loads and stays mostly south they might be a good fit.
Of course you are aware that if you blow a single tire, you are buying a new tire and a new rim too.
Not many roadside tire companies carry the wide based tire and tracking down a rim could be a problem.
My former boss tried them on a few of his trucks and he said he would never have them on any of his truck ever again.
