Help me guys...

I have a 2007 HD Nightster 1200n and need to purchase new tires. Tire shop and online resellers say these are the specs for new tires:
Rear 150/80R16
Front 110/90/R19 ....however, the rim size is actually 18" and I have, from the last owner, 120/90/R18

Can anyone confirm the stock rim size? Based on every image i see online, my bike has stock rims, however no tire reseller sees anything other than a 19" on the front.

 

I think 19inch front wheel is original wheel size.

To be sure call your local dealer and give them the vin#. They can tell you for sure.

 

Front 100 90 19
rear 150 80 16

 

 

it's amazing what you can find in the owner's manual.....
