Yes, according to this I am. So what are the drawbacks of having an over inflated tire? I would think the extra PSI would reduce rolling resistance, so is it just a comfort thing? Also, the rated range for my tires begins at the top end of this chart - if I was significantly lighter which should I adhere to - the tire rating or the chart? (ie, if I was 120 lbs (I am not, just hypothetical) rolling on 700x23 the chart suggests 94.5 psi, or 6.5 bar, yet the tire is rated for 8-12 bar.) I was running on the assumption that I should at least hit the minimum rating even though it is much higher than other wheels I have had.
