    This is a 2013 P85+ with 275/40-20 tires and it's triggering the low pressure monitor I'm assuming because of the size differential to the front 245/40-20.

    Will a 295/35-20 fit with the T-Sportline +40 offset???

    Probably best to pose this question to T-Sportline. Can also check the wheel/tire guide on their website

    We recommend the 275/40-20 tire size which is inline with the factory performance parameters.

    Performance Model S:
    245/35-21 Front Outer Diameter: 27.8"
    265/35-21 Rear Outer Diameter: 28.3"

    Our Recommendation:
    245/40-20 Front Outer Diameter: 27.8"
    275/40-20 Rear Outer Diameter: 28.7" (1.4% larger)

    *Outer diameter slightly varies from manufacturer to manufacturer.
    *Using a tire within a +/- 3% outer diameter of the factory tire is within tire industry accepted tolerances.

    What PSI are you filling it to? Are you sure you don't have a leak?
    I had the same 275/40/20 on my rears and I filled them to 42psi and never had a low pressure issue.

    If the rim is 10" wide, they will fit. Will it rub, I don't know.
