Hey everybody I'm new to this so bear with me if this is a no brainer question! I am trying to find 80 spoke wheels for an 03 Heritage. I do know the front tire size is 130/70 B 18 m/c 63H and the rear is 150/70 B 18 m/c 76H. I know the wheels are 18's but I don't know how to tell what width to get. The wheels are on the bike so I can't lay them down to measure them. Is there a way to tell what width they are by the tire size? Any help would be appreciated.

 

My guess is the ft. would be 3", the rr. 4.25".
Note; that I said guess!

 

18x4.25 for the rear.
