It's a 2014 America LT.(12000 miles...9 k of theses by me since last November) alloy wheels....no dings or obvious signs of running out of true.
Does its trick only in 2nd gear 25-30 mph....more evident under load..This morning tried lugging it 25-30 in 3rd...no vibes. Tried screaming it up to 25-30 in first....no vibes.
