The TPMS in my 2018 Ti is based on a tyre pressure of 35 psi. However, when towing my van I increase the rear tyre pressures to about 46-48 psi. Likewise, on unsealed roads I may go down as low as 25 psi and 16-18 psi on the beach. Is it possible to adjust the TPMS to accommodate these changes in tyre pressure? Thanks.
