We are phasing out Steelmate Tyre Pressure Monitoring Systems, this category of products will be replaced by a newer and better Tyre Pressure Monitor brand. Note that since Steelmate TPMS quality is very high, these external sensors will technically be able to last the user more than 5 years, as long as the sensor itself does not get significantly damaged. Thank you for your understanding while we go through this transition.
