Default Rear wheel upgrade ...size?

I have upgrade the front wheel and now its time to upgrade the rear.

Up front I am running : 21x3.5" Fat wires on 120/70 Wwall


I want to do a 18" rear....but unsure of the width and rear tire size.

Any recomendation, that'll fit the rear stock fenders, and 1" drop brackets.

Many thanks:

Pics would be awesome....

If memory serves...

140 tire on Touring models through 2003.

150 tire (may have to trim the belt guard) on 2004-2008.

180 tire on '09-up.

04 and up will take a 160 if you cut the bolts down

Only problem is 160 from metzler has lower load rating

If you change the rear fender to 07 se road king rear fender can get a 170/60/17 on a 17x4.5 rim or 180/55/18 on an 18x5.5

You got to run the 1 inch belt with the 180

If you do not want to change the fender a 18 x 4.25 wheel and 150 is abut as wide as you can go
