We installed the same rim/tire on the front as are currently on the rear and what a difference in the ride! Better control on the highway against those annoying cross winds, no more bone jarring experiences! The car rides much smoother! The only item we noticed is a slight reduction in zip in the first gear, say 10% or so, but what a difference! It was well worth it!
Milwaukee Smart car technition Eric had mentioned the difference and that other owners had made the change.... ran into another owner "Jim" whom recently did this too, all very positive...Thanks for the suggestion!
