Tough sidewalls can be the cause of blowouts and not the solution to the issue. Radial tires work well because of their thin supple side walls. A when a tire flexes it generates heat. The thin sidewall of a radial tire is designed to dissipate the heat. An underinflated or overloaded tire can generate enough heat to delaminate the tire. Often you can't tell by inspection that it has an issue, but sometimes a bubble will appear.
BFG beefs up their sidewalls on the radial to prevent rock damage, but there is a compromise because of it.
Check your sidewall tire temperature sometime after extended offloading when you air down to 12 psi or so. It may surprise you how hot it gets at low speed driving, especially with BFG's.
That said, I love my BFG A/Tís never failed me YET
