If bolt on spacers (even the “infamous” lug centric) we’re an issue/liability than tire shops would not service your vehicle which they do. Those slap on spacers though, complete different story, won’t touch them.
I’m gonna go ahead put this out there... some are gonna flip shit, whatever. Rough country 2in bolt spacers are LUG centric. I’ve put my truck through complete hell! And have never had any issues with driveability from Rough Country’s spacers. My hoe is not some pavement princess and still rides as smooth as a Cadillac on black top.
