I have a question about tire pressure.
These are on a hardtail MB that weighs about 36 pounds.  I weigh another 155. 99 percent road use. I have been keeping them at about 50 psi as recommended by a friend.
I've been reading that they should be more around 60 to 65 psi. Any recommendations would be appreciated.
Thanks

From the Serfas website:


Pressure:
65 PSI

*29 x 2.0   60 PSI
*700 x 32c   80 PSI

Yeah, max is 65. Is it safe to run at max psi?

I used to run them. But sold the bike.

I ran them lower like 40 but the roads, sidewalks and trails are bad here.

You can run whatever you want as long as it does what you want and the tires do not shift or snakebite.

PS: Tubed? Or can you do these tubeless?

I think you can go tubeless, but I use tubes (27.5").

What's snakebite?  Is that when the tire kicks sideways when you hit a pebble?

Thats when the tire deforms too much hitting a sharp edge like rock or curb causing the rim to puncture the tire in two places, looks like a snake bite.
