I was told by a wheel distributor that you could go with a
160 x 18 on the rear, said it would fit with no spacers.

 

I have another post going on this same topic...so i figured i would post this here as well.

Hey...good info on this gang!

I found the Pingle rear spacer.
http://www.pingelonline.com/rear_sprocket_spacer.htm
I will either order one from them today or contact my local aftermarket dealer and see if he can get one...I have a 10% discount with him, plus he can get parts quicker than I can.

Does anyone happen to have a pic of what the set up looks like with the spacer and the 140 tire installed. I would like to see the actual spacer attached to the bike and how it 'moves' the drive belt. There is quite a bit of 'play' room in the primary where the drive belt contacts the primary gears, I am just courious to how this looks.

 

The space issue is with 2000 - 2003 FLHRs. The Pingel spacer allows the 2004-and-up tire to be run with no cutting, rubbing, removing, ect. It tracks great and isn't noticeable on the rear wheel. The better stability is evident from the first time you hit the road at highway speed. Smile for the camera!

 

I tried the 140 on my 01 Ultra and it works going forward, but I changed back because of the tire rubbing so much going backward. It might be different with brands other than Dunlop. The newer bikes use a slightly narrower belt to accomodate the wider tire. ( At least that's what I was told! )

 

i run a 150 with no issues....140 on the front

 

I have the Pingel spacer and it works perfect...
