You can do the 3.5 rear. That's what I have on mine. It's a custom rim. I also know on 98's you can do a 140 rear without changing anything and it should leave about an 1/8"from the stock 1 1/2" belt but if you widen the rim a 1/2" it will also widen the tire a little so the next thing you'll need to do is a sprocket spacer of 1/4" to be able to use the 140 tire. There is still enough movement on your drive pulley to be able to move the rear pulley to the left a little and still track on the drive pulley properly.

Recommended wheel size for a 120/70/21 is 3.00-3.75...130 and 140 are available.

The chart posted in the below link is for model year Fatboys 2000 - 2015. Since you don't have a signature on your profile, I'm assuming you have a model year 1998 Fatboy from your profile name.
Didn't Harley in model year 2000 on the Softails go to the Twin Cam 88B counter balanced engine with a different frame, along with a new rear suspension, one piece fuel tank, and better brakes? If so, isn't it than possible the chart is correct for a Fatboy?

I totally disagree with that chart for a Fatboy. Stock is correct. However there is no way you can get a 21" rim on the front with a stock fender. I am running a 19x3 w/120/70/19 Metzeler and only have a 1/2" clearance to the fender. Also a 3" rim is doable for 120 series tire but if you go beyond that you would be pushing it.

Keep in mind that mounting the same size tire on a wider than stock rim will bring the sidewalls further out. You say you have no clearance now, going to a wider than stock rim isn't going to improve the situation.

Was gonna put this in the tire section but figured someone here would know. I have a 1998 springer softail and I want to get new rims. I know the front is a 21x2.15 and the back is a 16 but not sure how wide. The website with the rims I want have 16x3.5 and 16x5.5 so not sure what it would be. Thanks
