I see the matrix/sheet on tires here. They appear pretty tame when I look them up.
I also see images of RRS with beefy off-road tires - even though the tire manufacturers sites do not pull up a compatible option. Realizing there is more rubber = rub with lugs, does anyone have experience with a specific 20" mud or off-road tire and size that I can reference as compatible? I'm looking for a second wheel/tire set. TIA
