    Maxxis Raze max load

    I just noticed that my Maxxis Raze have a max load of 165 lb written on the sidewall. I have not seen anything like this before and I weigh 30 lb more than that. Is a max weight common? And is it commonly ignored? Thanks

    The tire doesn't know what you weigh. It only knows what air pressure is in it. It'll deform until the contact patch is big enough for any given air pressure. On the web site it has a max. pressure of 75 psi. I'd say as long as you run less pressure than that (please tell me you do) it should be fine.

    Are you saying you weigh 330lbs? Or did you forget that load is spread across more than one tire?

    Well I pop wheelies and ride manuals all day long, so I gotta worry about this stuff. J/K
    I didn't think of my weight distributed between the tires, though
    I weigh 195 and have been riding at 52/60 psi fr/rr.

    Seems high. I know the max is 75, but I think you'd be happier in the 40's.

    Big person, little tire - I was running 37 and 45 psi front and rear on my Hutchinsons. Sidewall gives them at 34mm, and I weigh about 150 lb. I found "my" pressures by experimentation, and while 45 rides a little harsher than I'd like, I got pinch flats at 40.

    So 52 and 60 could be right on.

    I am, as AndrwSwitch states, relatively heavy at 195lbs. So I'm running a bit higher psi than the lighter folk. As a mountain biker that has been riding tubeless for years, I'm well aware of the concept of using lower pressure for better traction, comfort, rolling resistance, etc. I run my MTB tires (2.0-2.2 widths) between 25-30 in the front and 28-35 in the rear. But "real" cross tires are new to me, I raced before on my 29er with the 700x40c Ritchey Speedmaxes at about 40/45 psi fr/rr. Now that I'm on a proper cross bike with more proper cross tire widths, I am definitely a newbie at the pressures. The 52/60 is my starting point and I expect to work downwards. Although I did pinch flat the rear this morning and I don't even remember hitting anything.

    I'm your weight too. Sounds like you've got it under control - though I'm definitely surprised you pinch flatted at 60.

    I'm surprised, too. But to be honest, it has been one of those days where I'm the nail instead of the hammer. Hopefully this is the negative karma getting worked out beforehand so I have great luck in my 38-mile mountain bike race on Saturday!
