Tires should be checked when cool. Set the pressure to the amount shown on the frame sticker. If you don't have the frame sticker a good pressure to use is betwen 30/33 and 33/35 psi. Some folks use the lower pressure in winter. Also, when tires are new they have a release compound residue that needs to be gradually scrubbed off with riding wear. It is slippery so if you ride really hard on new tires you might do some sliding.
