Street or less rolling resistance Replacment tires ? for the fat rims...I'm in Canada

Okay, a little more info would be helpful for me. I've got Kenda Juggernaut 4" tires (98-559) front and rear on a Shaka cruiser that I've had a few weeks.
I had bought a Duro Beach Bum 3" tube and tire (70-559), more a street tread to install.
But it looks so much narrower than the Kenda that I'm wondering if it will seat on the rim.
The outside measurement of the rim is 3.25 inches which translates to 82+mm.
How much reduction to get to the internal rim dimension should I figure?
Don't want to remove the 4" if the 3" won't work. Appreciate any input.
Thanks. Jeff

Jeff, I don't think the tire/rim tables really address your specific combination.

I would recommend mounting the new tires and then checking the profile.

You want a nice round shape... try to avoid a lightbulb or bell-shaped profile.

I hope this helps... take a look at the referenced article for more details. ;)

This is from Duro site and it is on a 100mm rim 😲

Dono Be - thanks! That's just what I wanted to know. I was concerned about the bead seating properly; didn't really think about how it would spread out the tread against the road. Or the sidewall. I was also concerned about the reduced height of the whole wheel compared to the 4" knobby. Was thinking it would drop the height by about 2". I'll report back if I put it on. Thanks again.

FlatSix - thanks, thats very helpful. Looks like the 3" tire might work but not be ideal.

Hey Great ! Im trying to get my hands on those tires as well. Don't forget to change the wheel diameter on the display computer. It will be different from the VOLT BIKE but here is how the YUKON bike is done.

Dono Be - thanks again, that's also helpful. My display manual says to set it for 28" (on a 26" rim) if its a fat tire. But the display shows 70. which I now interpret to be 700 mm, which translates to 28+ inches. Voila! So, my speed and mileage in MPH is accurate after all.
