Can anyone tell me what size wheels and tires I can put on my 2012 Heritage Softail Classic. It has 16" wheels front & back now. Do I have to stay with 16"? I don't want to modify the fender or bike, not ready for that yet. I appreciate any help with this. Thanks.

 

18's 21's. I had an 18 in front, 16 in the rear, went back to my OEM wheels. I have brand new tires for them so I think when the tires on my 16's wear out I'll put the Fat spokes on just to save a little money.
