Has anyone out there that has changed wheels and tires on ther Titan had any vibration in there trucks? I had a set of 18 centerline Lexi III wheels with the factory goodyear gsa, and had vibration at 45 and 70mph. The tires were road forced on a hunter machine and everything was good before mounting. I ended up sending the wheels back to centerline and bought a set of factory LE wheels from another member and I am having the same problem. The truck ran fine with the XE wheels. Any ideas?
