Default 08 SG wheel question

My winter project was to put a 21 inch spoke wheel on my 08 FLHX As always things are snowballing and I need some help. I am running the stock wheels and tire size with American Elite rubber. I know I will need a 120/70-21 radial tire up front so from what I have read I will need a radial back tire as well as you don't want to mix them. If I buy another tire for the rear I want to go as wide as I can. I have read many posts about fitting a 160 and up to a 180 with some mods. My question is can I grab up a used 2010 or later rear wheel to get to a wider rim? I see these on eBay for under $200 quite a bit. I am good with modding the fender but need an easy on the wallet option for the rear wheel.

Thanks

Can't speak to putting a 2010 rear wheel as I went with a matching rear when I bought my 21" front, but I do remember some saying the 160 was less stable at highway speeds than the 150. You might want to do a search on that aspect of it first.

Thanks pingman68 for the tip. I am hoping someone will chime in on the wheel question as I dont want to buy a custom rear wheel to get the added width if a stock take off from a later year will get the job done.

I've run both a 150 and 160 on my 07 which has the same size swingarm as your 08. The 150 fits easy on the factory 3 inch rim. The 160 was a real bear to mount and inflate. I mount my tires by hand so that adds to the difficulty. I've been in shops that refuse to mount 160's on 3 inch rims so that may hinder you as well. The 09 and up rear wheel is I believe 4.5 inches wide. I don't see how that would fit without some swingarm and fender alterations.

It is 16x5" wide rim on 09-later Touring with integral "cush drive". Those 09-later rear wheels it won't fit your 08 unless you have the skill or pay someone for the extensive modifications needed to make that happen. A couple members have done it

Also I think you'll find the 120/70-21 normally are a Bias tire.

FWIW there is a 130/60-21 American Elite (again also a Bias)

I have a 160/70 rear tyre in my 1990 Glide, along with several other mods, but on a 4.5"x17" rim. Doesn't seem very wise to me to squeeze a 160 on a stock 3" rim. My tyre is a radial, which I use with a bias front. That combo is fine, but as you point out, when using a radial front we should also use a radial rear. Having said that it is a long time since I saw anything in print confirming that.

So I did some more surfing and multihdrdr was right on with there being 120/70-21 options in a bias tire. It won't be a matching tire to the rear as Dunlop does not offer one but I can at least get the front end project knocked out without changing the rear tire.
