Does it exist any device in high cruising aircraft which reduces wheel pressure in order to adjust with decrasing ambient pressure at high altitudes?
No, and it is not necessary. Tire pressure is not like for cars, it is much higher, 200psi / 15bar to give a rough estimate. Therefore the additional .7 bar / 10 PSI due to the atmospheric pressure change is not relevant (< 5%). The pressure change due to heat from the brakes after landing is worse.
