"Also make sure you tell the tire fitter that there are TPMS sensors fitted
behind the valves so that they don’t damage them !"
By all means!!! Especially if it is not a Triumph dealer. And if they will allow it, ask to be able to tell the technician that is mounting the tires, FACE TO FACE! Experience speaking after telling TWO different individuals (sales person, and service manager), and it never got relayed to the tech, who broke mine. Replaced at their cost, but delayed getting it back together.
