More progress!

I swapped my other wheel set over with new front tires. Still using same tire and size and pressure, just on a much lighter wheel. Never got to weigh them though, so the true gain is a mystery. It feels good though, and despite still missing smooth covers and center caps I think Iíve gained mileage with these. More data to come!

Worth noting that prior to the wheel/tire swap with careful throttle use and on flat ground I could manage 48-50mpg instant at 60mph. I guess ditching the mirrors and the fender vents and the front tire strakes were helping?
