TPMS ISSUES

[limechallenger]

So I finally bought my new tires, Cooper Discoverer AT3/XLT's my new issue is the installer put them at 40psi, so now my TPMS fault is always screaming at me! I'm driving a 2020 Rebel with the Coopers in a 295/70 r18, I want to get the most out of these tires mileage wise and longevity. So do I bring the pressure up to 55 in the front and 45 in the rear to match the trucks settings or adust the settings to match the tires? I will need to make a adjustment for the larger diameter anyway ,so do I buy something to do both adjustments?

Alfaobd can change both settings I believe. Do the chalk test for psi if you are unsure.

If the coops are P and not LT rated, they max out at 51. If they’re LT’s just air them up.
