Max PSI on tubeless gravel wheels?

Postby Chris K » September 13th, 2019, 4:39 pm

Hello all, I am hoping to tap into the collective brain trust of MMBA. I am putting some Kenda Slant 6’s (29x1 8 ) on my giant TCX Advanced SX. They are going on the stock PX2 rims which have a inner width of 19mm and outer width of 24mm and are tubeless ready.

My question is, since I do numerous mixed surface rides I sometimes like to air up the tires and hit some long stretches of tarmac....what is a safe max PSI for tubeless setup? I know generally from my MTB’s 45psi is the general rule, is that true on narrower rim as well? I’d hate to blow off a tire while bombing some down hill.

Thanks for the input.

FWIW, on my 43mm Gravel King SKs (about 1.7") I run 36 PSI front and 38 PSI rear. On 21mm internal width rims. On mixed dirt/pavement surfaces. Keep in mind that higher PSI doesn't mean lower rolling resistance.
