These tires are Bontrager H5 26x2.00, supposedly HardCase. They are marked to "inflate between 60 PSI/4.1 BAR to 80 PSI/5.5 BAR. Inflate to the lower end for gravel paths, upper end for paved paths. Since we ride both, ours are around 70 PSI. I'm told to check the pressures every 1-2 weeks if you ride a lot, as they will lose pressure over time. They are also "directional" tires, in that the tread should be properly oriented, and each tire is so marked with a directional arrow if you remove them for and reinstall them.

Hope this is what you wanted to know.
