I’ve actually been reading my manual and the more I read the more unsure I am about getting new 20” rims and tires. The manual talks about improper tires and rims affecting the VTM-4, ABS and VSA Systems. Are these trucks so advanced that tire/wheel change could impact these systems in an emergency situation causing them to fail or overcompensate? Have any of our fellow members with 20” tires had them on long enough to find out if these systems are adversely affected, even if you stay within the same overall tire dimensions, or is this just another corporate out should something go wrong? Any comments out there fellow members? Still on the fence!
