My rear tire was a Dunlop 403 but I ordered a 140/90/16 as tire finder on Dennis kirk said. New tire is a lil wider, am I ok or is it gonna be an issue when I put it on tomorrow?
I recently put a Metzler 888 85 16 on my 01 Road King (should be same size as yours I believe???) and it is not only wider (and fits) but also taller. Now my speedometer matches my GPS speed.
The 140/90 is slightly larger in diameter than the MU. You may find you have very little clearance with a 150, if you have the 1 1/2" wide belt. I have used one, but only after changing to the later spec narrow belt.
