I like the Suami tires, but I will have to request that they make heavy duty 20”x 2.25” cycle truck tires. Even if they need to call them Moped tires.
I did find a Moped tire I like; the Pirelli-ML75 2.5”/16” rim and approximately 22-inch diameter. But I can't help wonder what the rolling resistance is, not that I really care, I have bionic legs.
How ever I will need to find an easy way to build a fork that will hold it. But it's worth a try.
those Big ****** rims look ok but I used to use Sun rim's BFR until they stopped making them. then I was thinking of using steel rims with disc brakes.
