Only by people with altered trucks. Everyone had an opinion but never proved 285/60/20 would actually fit on a STOCK truck...or provided pics confirming this. That's the problem..opinions from people with altered trucks..no pics and facts. The original question was how big on a stock HD? A recent poster just confirmed 275/65/20 fits, but will a 285/60/20 fit = a bigger tire again? And even more recently and specifically the BFG KO2? As it sits this forum is still waiting +80 posts later for an actual answer on the BFG 285. At least no one started an entirely new post and utilized the current threads to be efficient and keep data consolidated.
