Okay, I was not aware of that. I heard of Perilli tires. Not sure if I spelled it correctly. Would you know anything or heard from these brand?

 

I've heard the Pirelli Night Dragons are pretty good. Otherwise I haven' heard much about Pirelli.

Michellin seems to be a new favorite tire of some small shops and maybe even HD.

You should be ok with either one. Still; the E3's are some dang good tires. The grooves are all but eliminated.

 

Not a problem. I know I have 'issues' any more as I have aged it has just gotten worse..

 

Hi there, I noticed that it was common that a size bigger would most likely fit on a 2006 road king custom from its original size. But I was wondering if you or if anyone has had to make any type of modifications to the belt or any of the parts by the rear wheel area. I wish to research this before making the expense...Also can radial tires be used?

 

Yes. You can use a radial on the rear.

Can't tell you for sure if you can go one size wider but as a general rule it's ok to do. If you want to be sure you can check the clearance with your existing tire, measure the tire width, and figure out how wide you can go. Then go down to the shop where the tire is and measure it to be sure.

 

Before taking that as gospel, visit the tyre maker of choice and check their recommendations for your model! It is true they seem to mix tyre types more these days than of old. It is all very well for us novices out here to think things like that, but the experts are the tyre firms. If it will help email them with specific questions about their tyres.

I have just fitted a 2007 swingarm with 2005 wheel to my old Glide, along with a 150 Avon Venom. There is plenty of room with the later spec narrow belt to get the belt guard in as well. Beware however that the nominal width of any tyre is probably different to its fitted width. I estimated that I could get my earlier wide belt in with the 150, but it didn't work out, because the 150/80 was actually wider than on Avon's website. Some tyres are stated as being significantly wider than their nominal size.

 

My '05 UC just barely had room for the standard size tire. I can't imagine attempting to fit a larger one in there.

 

Great advise, Thank you all for your response.
