    Jumbo Jim 4.8 air pressure

    Does anyone run pressures lower than 4 psi when tubeless? Had an issue leaking from the bead when running 3.5 psi in the rear tire. I only tried this low of a pressure for snow riding. Rims are mulefut 80ís with their yellow tape. Thanks

    So, 3 psi works. Oops. Turns out my last dose of stans was from last season but after adding some I went for a quick ride but maybe it needed more time cause it was still weeping some and loosing some air by the time I made it back. Right now tho it stopped leaking. Iíll air down and go for a ride tomorrow and see what happens

    Ditch the Stan's and go with Orange Seal Subzero!!!! I cannot emphasize enough that Stan's purchased within the last 2-3 years is terrible and does not seal very well at all!
