D2's came with 2 tire size options, 16" and 18". Any issues switching between the two sizes either way (up or down)? I guess the speedometer/odometer will be off? Other than obvious things such as ground clearance, looks, anything to worry about? Were the brakes set-ups the same?

 

nothing should change and no issues either way. changes come from overall diameter and size of the rubber

 

yes, I do see that the OEM available sizes have just about the exact same diameter. I just assumed the 16" would have a smaller diameter Thanks
