    2015 TRD Off Road Prerunner
    I just put new 265/70r16 Cooper Discovere ATS 4s on my 2cnd gen TRD OR Prerunner. The sill sticker says to run 29 psi front /32 psi rear but the tire shop filled them to 35 psi all around. Should I lower the pressure to the factory spec? I'm going to be towing an 1100 lb camper trailer on a 1500 mile trip soon. Does that affect what tire pressure I might to run at?

    I just put these on my 3rd gen albeit a larger size
    285/70/17. I emailed Cooper and ask the question because of having a larger tire, of course they recommend using the OEM placard. I did a chalk test and ended up with 34-35 psi. Hope that helps.

    I'd run 35psi in the rear for towing ~1500lbs on a SL P metric tire.

    You run lower pressure in the front, especially towing as there is less weight on the front axle. I'd run 29-30psi on the front.

    Also, before you go, check your spare!!!

    I have the AT3 4S and I just did my first rotation. Very happy with them.
