I need to get a new set of tires for my 2000 Super Glide, it has a 130/90B16 on the rear now but I want to go wider. Does anyone know what I can put under it without changing anything from stock?

 

You can go to the Metzler website and look up your year and Model. It will show the stock and optional size. I have a 99 FXD and I went with the optional 140. Not sure yours is the same.
It does look a bit wider on the bike.

 

That sounds more like it, I am in Germany for a few years and the HD shop said I could go with a 150, I don't see that fitting under. Thanks bro
