I did notice about a 2 mpg drop in my mileage after changing over to the car tire, thanks for asking, I had forgotten about that. The winter gas may be hurting my mileage some too and I think I'll add some carb cleaner this week and see if that makes any difference. Someone on another forum asked about my chain and although I keep it well maintained and it doesn't have any noticeable wear on it and the sprockets look like new except for missing the paint on the teeth, it does have over 30,000 miles on it, so maybe it could be adding some resistance just through friction of the old pins or something. Thanks for the ideas and advice guys.
