I have an 09 FLHRC and I got a real good deal on a friends take-off tires and rims. That being said the rear tires are the same size 180/65B16. But my front tire is 130/90B16 M/C 67H and the new one is 130/70B18 M/C 63H. I am changing the rims and tires so what I'm asking is will it handle differently with the new front rim and tire being bigger?
