I swapped the eom size Michelin tires for Goodyear plus zero 25570r16 Wrangler RT/S tires. I am experiencing severe vibration from the wheels and they were just balanced. The vibr comes at about 50mph and increases w/speed increase. Would the plus size have anything to do w/this or is it just the Goodyear tires? Any help appreciated. No vibration until I switched to the new tires?
