Tire Pressure - Hutchinson Cross Comp(5 posts)

Tire Pressure - Hutchinson Cross Complexington476

I just got a set of Hutchinson Cross Comp size 26x1.3, for my mountain bike (hardtail - no lockout). They look just like cross tires for 700c. The pressure recommendations I am getting form Hutchinson are 57 PSI to 71 PSI regarding the terrain (71 on stony or dry terrain and less on muddy terrain).

Now, on the side of the tires it says 36 PSI for competition. I am 155 pounds. I have cross practice tomorrow and a race on Saturday, this will my first time with these tires. Racing in Michigan.

What should I be setting the PSI at on these tires (min-max)?

Thanks

youll find that the numbers are just a refrence tool. in general softer for rough(bumpy)and mud. harder for dry and rocky. try both and somewhere in between during practice so that race day youll know exactly what youll need.
I'd start somewhere in the middle of the range...AJS

...of what Hutch recommends, so 60-65 PSI, then adjust accordingly to course conditions, my weight, riding style, etc.

60-65, that high... Is it common to run CX tires that high? I was thinking in the range of 40...
Lower range...Spunout

my newbie comments, I have been training on these tires for three weeks (came on my '03 Jamis Nova) and I have the front as low as 42. Hit some pretty big holes, no problem. I would increase for a rock-strewn road maybe. Also use 50 at the back, no problems either. Off camber descents (grass) feel like I'm on rails. I weight 160 btw.
