Wide Rear

What is the widest rear tire I can mount on the standard rear rim on a 2001 Softail Standard?

I’m hoping I can find someone with some experience with choosing the proper brand of tire for the rear wheel and still not rub the drive belt. Someone told me who makes a slightly wider tire than Dunlop but of course I can’t remember who told me or what brand I need. Thank you for any help.

The belt is not the only problem you will find when going with a wider tire. You also have to watch out for clearance issues up in the rear fender.

IIRC your bike came with a 130 width tire stock. I have seen some people fit a 140 but it was close.

The Metzeler ME 880 Marathon in 140/90B16 is a popular tire for this.

The Avon Venom is also another choice.
