    Tire pressure for gravel grinder?

    wondering what the folks who do gravel grinders do for tire pressure. I will be doing a multi-day GG next week on my Nature Boy with CST Servant tires. The roads/trails range from bad to worse...lots of loose gravel.

    Depends on your body weight and riding style, but I would start at 50 psi (for 38c CST Servant tires) and go down from there. The lower the pressure - the better traction you will have around the corners at speed.

    I am about 200.... I am not worried about corners as this is mostly straight and flat. I am more concerned with soaking up chatter from ATV ruts.

    Wow, chatter from ATV ruts is hard to soak up since it is so rhythmic - you can get quite a bounce going. Just run the highest volume tire that will fit. If you can swap a fork that takes a 2.1" or larger 29er tire, and run it at like 30-40psi - it will help alot. Otherwise - bring a bottle of Advil!

    I'm also 200 lbs. I use 45 front & 60 rear on 700x40 tires.
    When I ride my bike I feel free and happy and strong. I'm liberated from the usual nonsense of day to day life. Solid, dependable, silent, my bike is my horse, my fighter jet, my island, my friend. Together we will conquer that hill and thereafter the world.
