Considering buying a aftermarket wheel and tire set for my 2015 Street Glide... I'll run a 21" up front with a 130/60 tire. A bit confused with the many rear options 16" 17" or 18" rims and then what size tire? Any suggestions?
Chose your style of wheel, then contact a suitable supplier! We have HDF sponsors who sell wheels and will be pleased to help you decide. Just as there are several options of front wheel sizes, there are ditto for the rear. The larger the rim diameter, the lower profile will be the suitable tyre to go with it. If you have a preferred brand you can check their website to see if they have suitable tyres for the larger rim diameters.
I went with 16 to the rear and 21 front. Main reason is I wanted the widest whitewall for the rear. If I didn't have the white walls I would still go with 16 to the rear.
I'm considering a 21" front too but I'll probably leave the rear stock....for what a rear wheel costs I can get the bags that drop down so it wouldn't show.
