When I bought my Spyder the pressure was way over the recommended limits. So I let out air and have my tires set at the max recommended PSI. Interestingly, my Spyder now feels a little more "squirrely" or "loose" than it did before. I'm wondering how everyone else has theirs set up. For reference, I'm riding in 60-80 degree temps in Albuquerque, with very low humidity and dry roads. (It's only sprinkled 3 times here in the last 6 months).
