DRW vs SRW safety, tire blowout
Every time the DRW vs SRW debate starts up, dually owners always point to the safety of having 4 rear wheels in case of a blowout while driving. What I am wondering is has anyone actually experienced ...

Nah, I looked up tire and wheel weights real quick. It’s close but depends on exact size/model etc. and someone on this forum is bound to nit pick the lack of absolute proof…lol.
Yes spring pack may be a bit heavier too. But it’s not the sprung weight that adds “much”. It’s the unsprung weight. Which the truck can handle just fine and minimal effect on braking distance either.
But when that weight becomes rotational, our little friend inertia shows up and poops all over some folks’s uninformed “theories”. (Or all those classes I paid a lot of money for to become an engineer were a farce….but I doubt it)
The 7lbs per lb is a rough rule of thumb but the point is, is rotational mass has a FAR greater effect than static mass.
