Upper door seals kill 70 to 80 % of highway wind noise. They were available in 70's on the squares but were later removed as cost savings(making an assumption on cost savings part). LMC sells new sets, or general 3/4 foam seal can be used instead. Tires are a bit rougher being E range rated. Wanted to ran D range, but tire store was resisting being that I have a 3/4 ton.
