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.
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.
With the explosion of Boost, Plus bikes, Mid Fat and other portly new rim and tire sizes for everything from road to cyclocross to gravel to mountain bikes, it’s a wonder there isn’t more confusion as to what will actually work together. And by “work together”, we don’t just mean whether or not...
