I have the 2.50x16 cast wheel on the back of my RetroStandard bike, with a 130/90-16 tire.  The fitment chart shows the tire is acceptable on that narrow rim (taller profile tires allow for more fitment than short profile tires).

I have no idea what size tires are available in whitewall....that is a research project for someone else!

Buying/changing tires and wheels is a time consuming and costly project.

I can't help but think this whole thing would be far easier/cheaper to buy a set of portowalls and see how they hold up!

Well my portawalls showed up today wasn’t expecting them till next week, so I was too excited and couldn’t wait so I started doing it.  First tire off and installed port wall and back on bike in 30mins the rear tire ….. well that was another story lol it was a real PITA !!! hard time trying to break the bead seal for one and then two the darn portawall kept popping out after filling with air lol after a couple hours of wrestling with it I got it all back together and set on the bike and cleaned up

What do you guys think ???

Ya I guess we will see how long they last and hold up lol

A couple months in now, how're they doing? I'm needing to replace my tires sooner rather than later and this thread's lead me to the same conclusion of just getting porta walls and saving myself some braincells hunting down  real white walls. Still though I would love to hear from a fellow savage rider
